What Is Climate Change?

what is climate change essay

Climate change is a long-term change in the average weather patterns that have come to define Earth’s local, regional and global climates. These changes have a broad range of observed effects that are synonymous with the term.

Changes observed in Earth’s climate since the mid-20th century are driven by human activities, particularly fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere, raising Earth’s average surface temperature. Natural processes, which have been overwhelmed by human activities, can also contribute to climate change, including internal variability (e.g., cyclical ocean patterns like El Niño, La Niña and the Pacific Decadal Oscillation) and external forcings (e.g., volcanic activity, changes in the Sun’s energy output , variations in Earth’s orbit ).

Scientists use observations from the ground, air, and space, along with computer models , to monitor and study past, present, and future climate change. Climate data records provide evidence of climate change key indicators, such as global land and ocean temperature increases; rising sea levels; ice loss at Earth’s poles and in mountain glaciers; frequency and severity changes in extreme weather such as hurricanes, heatwaves, wildfires, droughts, floods, and precipitation; and cloud and vegetation cover changes.

“Climate change” and “global warming” are often used interchangeably but have distinct meanings. Similarly, the terms "weather" and "climate" are sometimes confused, though they refer to events with broadly different spatial- and timescales.

What Is Global Warming?

global_warming_2022

Global warming is the long-term heating of Earth’s surface observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere. This term is not interchangeable with the term "climate change."

Since the pre-industrial period, human activities are estimated to have increased Earth’s global average temperature by about 1 degree Celsius (1.8 degrees Fahrenheit), a number that is currently increasing by more than 0.2 degrees Celsius (0.36 degrees Fahrenheit) per decade. The current warming trend is unequivocally the result of human activity since the 1950s and is proceeding at an unprecedented rate over millennia.

Weather vs. Climate

“if you don’t like the weather in new england, just wait a few minutes.” - mark twain.

Weather refers to atmospheric conditions that occur locally over short periods of time—from minutes to hours or days. Familiar examples include rain, snow, clouds, winds, floods, or thunderstorms.

Climate, on the other hand, refers to the long-term (usually at least 30 years) regional or even global average of temperature, humidity, and rainfall patterns over seasons, years, or decades.

500+ words climate change essay.

Climate change refers to the change in the environmental conditions of the earth. This happens due to many internal and external factors. The climatic change has become a global concern over the last few decades. Besides, these climatic changes affect life on the earth in various ways. These climatic changes are having various impacts on the ecosystem and ecology. Due to these changes, a number of species of plants and animals have gone extinct.

what is climate change essay

When Did it Start?

The climate started changing a long time ago due to human activities but we came to know about it in the last century. During the last century, we started noticing the climatic change and its effect on human life. We started researching on climate change and came to know that the earth temperature is rising due to a phenomenon called the greenhouse effect. The warming up of earth surface causes many ozone depletion, affect our agriculture , water supply, transportation, and several other problems.

Reason Of Climate Change

Although there are hundreds of reason for the climatic change we are only going to discuss the natural and manmade (human) reasons.

Get the huge list of more than 500 Essay Topics and Ideas

Natural Reasons

These include volcanic eruption , solar radiation, tectonic plate movement, orbital variations. Due to these activities, the geographical condition of an area become quite harmful for life to survive. Also, these activities raise the temperature of the earth to a great extent causing an imbalance in nature.

Human Reasons

Man due to his need and greed has done many activities that not only harm the environment but himself too. Many plant and animal species go extinct due to human activity. Human activities that harm the climate include deforestation, using fossil fuel , industrial waste , a different type of pollution and many more. All these things damage the climate and ecosystem very badly. And many species of animals and birds got extinct or on a verge of extinction due to hunting.

Effects Of Climatic Change

These climatic changes have a negative impact on the environment. The ocean level is rising, glaciers are melting, CO2 in the air is increasing, forest and wildlife are declining, and water life is also getting disturbed due to climatic changes. Apart from that, it is calculated that if this change keeps on going then many species of plants and animals will get extinct. And there will be a heavy loss to the environment.

What will be Future?

If we do not do anything and things continue to go on like right now then a day in future will come when humans will become extinct from the surface of the earth. But instead of neglecting these problems we start acting on then we can save the earth and our future.

what is climate change essay

Although humans mistake has caused great damage to the climate and ecosystem. But, it is not late to start again and try to undo what we have done until now to damage the environment. And if every human start contributing to the environment then we can be sure of our existence in the future.

ENCYCLOPEDIC ENTRY

Climate change.

Climate change is a long-term shift in global or regional climate patterns. Often climate change refers specifically to the rise in global temperatures from the mid-20th century to present.

Climate is sometimes mistaken for weather. But climate is different from weather because it is measured over a long period of time, whereas weather can change from day to day, or from year to year. The climate of an area includes seasonal temperature and rainfall averages, and wind patterns. Different places have different climates. A desert, for example, is referred to as an arid climate because little water falls, as rain or snow, during the year. Other types of climate include tropical climates, which are hot and humid , and temperate climates, which have warm summers and cooler winters.

Climate change is the long-term alteration of temperature and typical weather patterns in a place. Climate change could refer to a particular location or the planet as a whole. Climate change may cause weather patterns to be less predictable. These unexpected weather patterns can make it difficult to maintain and grow crops in regions that rely on farming because expected temperature and rainfall levels can no longer be relied on. Climate change has also been connected with other damaging weather events such as more frequent and more intense hurricanes, floods, downpours, and winter storms.

In polar regions, the warming global temperatures associated with climate change have meant ice sheets and glaciers are melting at an accelerated rate from season to season. This contributes to sea levels rising in different regions of the planet. Together with expanding ocean waters due to rising temperatures, the resulting rise in sea level has begun to damage coastlines as a result of increased flooding and erosion.

The cause of current climate change is largely human activity, like burning fossil fuels , like natural gas, oil, and coal. Burning these materials releases what are called greenhouse gases into Earth’s atmosphere . There, these gases trap heat from the sun’s rays inside the atmosphere causing Earth’s average temperature to rise. This rise in the planet's temperature is called global warming. The warming of the planet impacts local and regional climates. Throughout Earth's history, climate has continually changed. When occuring naturally, this is a slow process that has taken place over hundreds and thousands of years. The human influenced climate change that is happening now is occuring at a much faster rate.

What is climate change and why does it matter?

Climate change is the defining issue of our time . We have reached a pivotal moment in deciding our planet's future.

Find out what climate change is, why it matters and what it could mean for our collective future.

What are weather, climate and climate change?

Weather refers to atmospheric conditions, such as rain or snow, happening in a place at a specific moment in time. Climate is how much, on average, a type of weather will occur over a longer period.

Dr Joeri Rogelj is a climate scientist at Imperial College London's Grantham Institute who has contributed to and led several major climate change assessments. He explains, 'Climate change is how the characteristics of the weather we experience in a certain place change.

'It can get hotter or wetter on average or have more concentrated rain in a short period, but then get longer dry periods. All of that can be a result of climate change.'

Global warming is a term used interchangeably with climate change, although the latter is preferred because the warming atmosphere and oceans are just some of the effects we see.

'It's not just about temperature. Places are also becoming wetter or drier, and in some the seasons are moving. Most importantly, in a few regions and seasons, it may actually at times be cooler than we're used to. That's confusing if you just talk about global warming.'

Causes of climate change

The main driver of current climate change is the emission of greenhouse gases, most importantly carbon dioxide and methane . These are primarily released when fossil fuels are burnt. Meat and dairy production, producing cement and some industrial processes, such as the production and use of fertilisers, also emit greenhouse gases.

Greenhouse gases trap heat in our atmosphere. Since the mid-nineteenth century , the world has emitted over 2.2 trillion tonnes of carbon dioxide.

Joeri explains, 'Energy from the Sun falls on our planet and normally gets reflected back as infrared radiation. But instead of escaping back out into space, this radiation gets absorbed by molecules of greenhouse gases, which then emit them in all directions.'

This process causes more heat to be kept near Earth's surface, warming our world.

How do we know climate is changing?

There are measuring stations all around the world that keep track of air and sea temperature. From these measurements it's clear that temperatures are rising.

'There are many more indicators that tell us that the Earth is warming. For example, on a warming planet we would expect polar ice caps and glaciers to melt. It is clearly observed that those are melting,' explains Joeri.

We know that greenhouse gases are causing change. Thanks to studies that look at how carbon dioxide absorbs infrared radiation, for example, there is a scientific understanding of how the planet would warm as a result of emissions. This has allowed climate scientists to discount the theory that global warming is being caused by an increase in the Sun's intensity, for example.

It's also known that greenhouse gases are primarily emitted by fossil fuel combustion.

'To burn carbon and produce carbon dioxide, you need oxygen. The amount of oxygen that is in the atmosphere is reducing at exactly the right amount for the increase in carbon dioxide to be caused by combusting fossil fuels,' explains Joeri.

There is additional evidence in the ratios of different types of carbon. Fossil fuels are, essentially, ancient plants . Plants now and in the past preferentially take up carbon-12. In normal conditions, the ratio between carbon-12 and carbon-13 is constant.

'What we can see is that the ratio of carbon-13 in our atmosphere is going down at exactly the rate you would predict if the carbon dioxide increase was due to burning fossil fuels.'

Effects of climate change

Climate change does not have the same effects everywhere. The planet is generally getting hotter, but some regions and seasons can at times be temporarily cooler. Some places will see drawn-out seasons, while others may experience concentrated bursts of extreme weather.

Extreme weather events - such as hurricanes, floods, heatwaves , drought and  wildfires  - are predicted to become more intense and frequent.

'Pretty much any weather event is influenced by climate change. As scientists we can estimate how much climate change has made a certain event more likely or more intense than it would have been without climate change,' explains Joeri.

When the world warms, ice melts. Arctic sea ice could disappear entirely in a warming world, and Greenland and Antarctica's ice sheets could be destabilised. This would result in large sections melting, which would add more liquid to the ocean.

Ice also reflects the Sun's energy, so without ice, more heat is absorbed by the ocean . Water expands as it warms - this is known as thermal expansion. This effect means that the ocean takes up more space, causing sea levels to rise. Even with rapid emission cuts, sea levels are expected to rise by around 26 to 53 centimetres by 2100.

Along with melting ice sheets and glaciers, rising global temperatures could cause rainforests to die and widespread species extinctions.

The effects of climate change on us

How climate change will affect you depends on who you are and where you live.

Around 190 million people currently live in areas that, due to rising sea levels, are expected to be under high tide levels by 2100. This could cause a massive displacement of populations. Low lying atoll nations such as Tuvalu and the Maldives are incredibly vulnerable to this change and could be lost to the sea.

Hundreds of millions of people rely on seafood as their main source of protein. Warming and more acidic waters could destroy marine food chains by affecting their base, such as krill or coral reefs .

Longer-lasting drought could devastate crops, threating food security. Reservoirs drying up , as well as the loss of glaciers, could make drinking water scarce.

Increased precipitation can cause deadly flooding, as well as lowering indoor air quality. This could affect our health as dampness benefits moulds and fungi.

Around four billion people live in urban areas, and by 2050 this will have risen to an estimated 6.7 billion.

City dwellers are not exempt from climate change's effects. Urban populations usually rely on rural areas for inputs such as food and water. If climate change disrupts these important connections, it could heavily affect those in urban areas.

Natural disasters impact poor and vulnerable populations disproportionately hard and clearly expose the consequences of ignoring social inequalities . With extreme weather increasing, these populations face a heightened level of risk.

For example, the urban heat island effect amplifies the effects of temperature extremes in cities. Those unable to afford to buy and run air conditioning may find their health compromised.

The hazards of climate change also do  disproportionate harm to women and girls .

Joeri says, 'We don't know what will happen when, exactly. It's really hard to anticipate, particularly for populations that are already on the edge every year.'

People are also seeing climate change impact their mental health, experiencing a phenomenon known as eco-anxiety .

How does climate change affect biodiversity?

The natural world is delicately balanced . No species - including ours - is completely independent of all others. A 2019 report confirmed that over one million animal and plant species are now at risk of extinction as a result of human activities.

In the UK, an analysis of over 700 species has shown that more than 80% of trends between 1976 and 2005 indicate seasonal events are happening earlier. Differing rates of change could mean that species' lives are no longer synchronised with those they rely on.

Many plants are flowering earlier. Migrating birds arrive earlier, leave later and some even are getting smaller . Butterflies are emerging earlier . Birds and amphibians are laying their eggs earlier in the year. Some species are moving into new areas, such as kelps which form vital marine habitats.

A display of seaweed specimens at the Museum

Seaweeds are important for many reasons . They act as vital habitats. Some also help protect coastlines from erosion.

Insects are one of the most vulnerable groups, with less ability than mammals or birds to escape warmer temperatures. Loss of insects, which are a primary food source for many animals, a key pollinator of plants and whose numbers are already plummeting , could cause the ecosystem to collapse.

In aquatic ecosystems, activities to mitigate the side effects of climate change, such as building hard flood defences, can have negative effects. As sea levels rise, sea walls reduce the space for intertidal ecosystems. A rising sea could also damage important coastal habitats like sand dunes and cliffs.

Joeri says, 'The ocean looks homogenous, but it also experiences variations. There are ocean heatwaves, where if a particularly warm mass of water comes to an area like coral reefs, it induces loss and mass dieback.'

The loss of Arctic sea ice takes away a key habitat from animals including polar bears, seals and walruses. The ice is now declining at a rate of more than 12% per decade .

Climate change is just one of the stressors currently impacting nature. Sea use, invasive species, pollution and the exploitation of organisms are all factors in the threat to nature. Without drastic changes , it's expected that there will be devastating changes in biodiversity and ecosystems.

Is there any hope for the future?

Climate change has been a known problem for around 30 years. Starting to fix it earlier might have made this daunting task much easier.

Joeri says, 'We definitely know how to reduce emissions to a significant degree. We are seeing more impacts of climate change, but we can also see a heightened interest and concern in the general public.

'Ultimately, reducing emissions is really an issue of public and political will.'

Scientists taking samples from patches of ice

By understanding more about the planet, such as by studying the poles, scientists are able to estimate the consequences climate change will have © NASA Goddard Space Flight Center via Flickr ( CC BY 2.0 )

Over the past decades, scientists have estimated the potential impacts of the planet's average temperature rising by different amounts.

'Based on that information, governments have come together and decided that they don't want to exceed a 2°C rise. They want to be well below that and pursue efforts to make it as close as possible to 1.5 °C.'

The difference in outcomes between 1.5 and 2°C are considerable. The impacts are the difference of 70% or 99% of coral reefs dying or a summer free of Arctic sea ice once every 100 or 10 years.

Scientists have determined how much carbon dioxide can still be emitted before this temperature rise limit will be exceeded. This is called the carbon budget and it's relatively small.

Joeri says, 'It's currently 420 to 580 billion tonnes of carbon dioxide for having a two-in-three or a one-in-two chance of limiting warming to 1.5°C, starting to count in 2018.

'Today we are roughly emitting 42 billion tonnes a year. So, if you start today and are going to net-zero emissions , if you want a one-in-two chance, we should there by around mid-century.

'These numbers define the geophysical requirement. Scientists then use engineering and economic models to understand how we can transform society to stay within that emission limit.'

This transformation could include changes such as increasing the share of energy produced by renewables , changing the way food is produced , changing our diets to have a lower carbon footprint and changing the way we build houses and design cities .

Moving to net-zero emissions will not be a perfectly co-ordinated transition . It will take some countries to lead and show the world that moving to this new way of living and functioning is both possible and beneficial for other sustainability objectives, such as public health and food security.

But on whether we'll ever see a change for the better, Joeri says he's hopeful.

'Preferably we would have started 25 or 30 years ago, but I will take any year at which we start declining steadily towards net-zero.'

Climate Change Essay

500+ words essay on climate change.

Climate change is a major global challenge today, and the world is becoming more vulnerable to this change. Climate change refers to the changes in Earth’s climate condition. It describes the changes in the atmosphere which have taken place over a period ranging from decades to millions of years. A recent report from the United Nations predicted that the average global temperature could increase by 6˚ Celsius at the end of the century. Climate change has an adverse effect on the environment and ecosystem. With the help of this essay, students will get to know the causes and effects of climate change and possible solutions. Also, they will be able to write essays on similar topics and can boost their writing skills.

What Causes Climate Change?

The Earth’s climate has always changed and evolved. Some of these changes have been due to natural causes such as volcanic eruptions, floods, forest fires etc., but quite a few of them are due to human activities. Human activities such as deforestation, burning fossil fuels, farming livestock etc., generate an enormous amount of greenhouse gases. This results in the greenhouse effect and global warming which are the major causes of climate change.

Effects of Climate Change

If the current situation of climate change continues in a similar manner, then it will impact all forms of life on the earth. The earth’s temperature will rise, the monsoon patterns will change, sea levels will rise, and storms, volcanic eruptions and natural disasters will occur frequently. The biological and ecological balance of the earth will get disturbed. The environment will get polluted and humans will not be able to get fresh air to breathe and fresh water to drink. Life on earth will come to an end.

Steps to be Taken to Reduce Climate Change

The Government of India has taken many measures to improve the dire situation of Climate Change. The Ministry of Environment and Forests is the nodal agency for climate change issues in India. It has initiated several climate-friendly measures, particularly in the area of renewable energy. India took several steps and policy initiatives to create awareness about climate change and help capacity building for adaptation measures. It has initiated a “Green India” programme under which various trees are planted to make the forest land more green and fertile.

We need to follow the path of sustainable development to effectively address the concerns of climate change. We need to minimise the use of fossil fuels, which is the major cause of global warming. We must adopt alternative sources of energy, such as hydropower, solar and wind energy to make a progressive transition to clean energy. Mahatma Gandhi said that “Earth provides enough to satisfy every man’s need, but not any man’s greed”. With this view, we must remodel our outlook and achieve the goal of sustainable development. By adopting clean technologies, equitable distribution of resources and addressing the issues of equity and justice, we can make our developmental process more harmonious with nature.

We hope students liked this essay on Climate Change and gathered useful information on this topic so that they can write essays in their own words. To get more study material related to the CBSE, ICSE, State Board and Competitive exams, keep visiting the BYJU’S website.

What Is Climate Change?

Climate change is the significant variation of average weather conditions becoming, for example, warmer, wetter, or drier—over several decades or longer. It may be natural or anthropogenic. However, in recent times, it’s been in the top headlines due to escalations caused by human interference.

What are the Causes of Climate Change?

Obama at the First Session of COP21 rightly quoted “We are the first generation to feel the impact of climate change, and the last generation that can do something about it.”.Identifying the causes of climate change is the first step to take in our fight against climate change. Below stated are some of the causes of climate change:

  • Greenhouse Gas Emissions: Mainly from burning fossil fuels (coal, oil, and natural gas) for energy and transportation.
  • Deforestation: The cutting down of trees reduces the planet’s capacity to absorb carbon dioxide.
  • Industrial Processes: Certain manufacturing activities release potent greenhouse gases.
  • Agriculture: Livestock and rice cultivation emit methane, a potent greenhouse gas.

What are the effects of Climate Change?

Climate change poses a huge risk to almost all life forms on Earth. The effects of climate change are listed below:

  • Global Warming: Increased temperatures due to trapped heat from greenhouse gases.
  • Melting Ice and Rising Sea Levels: Ice caps and glaciers melt, causing oceans to rise.
  • Extreme Weather Events: More frequent and severe hurricanes, droughts, and wildfires.
  • Ocean Acidification: Oceans absorb excess CO2, leading to more acidic waters harming marine life.
  • Disrupted Ecosystems: Shifting climate patterns disrupt habitats and threaten biodiversity.
  • Food and Water Scarcity: Altered weather affects crop yields and strains water resources.
  • Human Health Risks: Heat-related illnesses and the spread of diseases.
  • Economic Impact: Damage to infrastructure and increased disaster-related costs.
  • Migration and Conflict: Climate-induced displacement and resource competition.

How to fight climate change?

‘Climate change is a terrible problem, and it absolutely needs to be solved. It deserves to be a huge priority,’ says Bill Gates. The below points highlight key actions to combat climate change effectively.

  • Energy Efficiency: Improve energy efficiency in all sectors.
  • Protect Forests: Stop deforestation and promote reforestation.
  • Sustainable Agriculture: Adopt eco-friendly farming practices.
  • Advocacy: Raise awareness and advocate for climate-friendly policies.
  • Innovation: Invest in green technologies and research.
  • Government Policies: Enforce climate-friendly regulations and targets.
  • Corporate Responsibility: Encourage sustainable business practices.
  • Individual Action: Reduce personal carbon footprint and inspire others.

Essay On Climate Change in 100 Words

Climate change refers to long-term alterations in Earth’s climate patterns, primarily driven by human activities, such as burning fossil fuels and deforestation, which release greenhouse gases into the atmosphere. These gases trap heat, leading to global warming. The consequences of climate change are widespread and devastating. Rising temperatures cause polar ice caps to melt, contributing to sea level rise and threatening coastal communities. Extreme weather events, like hurricanes and wildfires, become more frequent and severe, endangering lives and livelihoods. Additionally, shifts in weather patterns can disrupt agriculture, leading to food shortages. To combat climate change, global cooperation, renewable energy adoption, and sustainable practices are crucial for a more sustainable future.

Climate Change Sample Essay 250 Words

Climate change represents a pressing global challenge that demands immediate attention and concerted efforts. Human activities, primarily the burning of fossil fuels and deforestation, have significantly increased the concentration of greenhouse gases in the atmosphere. This results in a greenhouse effect, trapping heat and leading to a rise in global temperatures, commonly referred to as global warming.

The consequences of climate change are far-reaching and profound. Rising sea levels threaten coastal communities, displacing millions and endangering vital infrastructure. Extreme weather events, such as hurricanes, droughts, and wildfires, have become more frequent and severe, causing devastating economic and human losses. Disrupted ecosystems affect biodiversity and the availability of vital resources, from clean water to agricultural yields.

Moreover, climate change has serious implications for food and water security. Changing weather patterns disrupt traditional farming practices and strain freshwater resources, potentially leading to conflicts over access to essential commodities.

Addressing climate change necessitates a multifaceted approach. First, countries must reduce their greenhouse gas emissions through the transition to renewable energy sources, increased energy efficiency, and reforestation efforts. International cooperation is crucial to set emission reduction targets and hold nations accountable for meeting them.

In conclusion, climate change is a global crisis with profound and immediate consequences. Urgent action is needed to mitigate its impacts and secure a sustainable future for our planet. By reducing emissions and implementing adaptation strategies, we can protect vulnerable communities, preserve ecosystems, and ensure a livable planet for future generations. The time to act is now.

Climate change refers to long-term shifts in Earth’s climate patterns, primarily driven by human activities like burning fossil fuels and deforestation.

Five key causes of climate change include excessive greenhouse gas emissions from human activities, notably burning fossil fuels and deforestation.

Essay on Climate Change

Climate Change Essay - The globe is growing increasingly sensitive to climate change. It is currently a serious worldwide concern. The term "Climate Change" describes changes to the earth's climate. It explains the atmospheric changes that have occurred across time, spanning from decades to millions of years. Here are some sample essays on climate change.

Essay on Climate Change

The climatic conditions on Earth are changing due to climate change. Several internal and external variables, such as solar radiation, variations in the Earth's orbit, volcanic eruptions, plate tectonics, etc., are to blame for this.

There are strategies for climate change reduction. If not implemented, the weather might get worse, there might be water scarcity, there could be lower agricultural output, and it might affect people's ability to make a living. In order to breathe clean air and drink pure water, you must concentrate on limiting human activity. These are the simple measures that may be taken to safeguard the environment and its resources.

The climate of the Earth has changed significantly over time. While some of these changes were brought on by natural events like volcanic eruptions, floods, forest fires, etc., many of the changes were brought on by human activity. The burning of fossil fuels, domesticating livestock, and other human activities produce a significant quantity of greenhouse gases. This results in an increase of greenhouse effect and global warming which are the major causes for climate change.

Reasons of Climate Change

Some of the reasons of climate change are:

Deforestation

Excessive use of fossil fuels

Water and soil pollution

Plastic and other non biodegradable waste

Wildlife and nature extinction

Consequences of Climate Change

All kinds of life on earth will be affected by climate change if it continues to change at the same pace. The earth's temperature will increase, the monsoon patterns will shift, the sea level will rise, and there will be more frequent storms, volcano eruptions, and other natural calamities. The earth's biological and ecological equilibrium will be disturbed. Humans won't be able to access clean water or air to breathe when the environment becomes contaminated. The end of life on this earth is imminent. To reduce the issue of climate change, we need to bring social awareness along with strict measures to protect and preserve the natural environment.

A shift in the world's climatic pattern is referred to as climate change. Over the centuries, the climate pattern of our planet has undergone modifications. The amount of carbon dioxide in the atmosphere has significantly grown.

When Did Climate Change Begin

It is possible to see signs of climate change as early as the beginning of the industrial revolution. The pace at which the manufacturers produced things on a large scale required a significant amount of raw materials. Since the raw materials being transformed into finished products now have such huge potential for profit, these business models have spread quickly over the world. Hazardous substances and chemicals build up in the environment as a result of company emissions and waste disposal.

Although climate change is a natural occurrence, it is evident that human activity is turning into the primary cause of the current climate change situation. The major cause is the growing population. Natural resources are utilised more and more as a result of the population's fast growth placing a heavy burden on the available resources. Over time, as more and more products and services are created, pollution will eventually increase.

Causes of Climate Change

There are a number of factors that have contributed towards weather change in the past and continue to do so. Let us look at a few:

Solar Radiation |The climate of earth is determined by how quickly the sun's energy is absorbed and distributed throughout space. This energy is transmitted throughout the world by the winds, ocean currents etc which affects the climatic conditions of the world. Changes in solar intensity have an effect on the world's climate.

Deforestation | The atmosphere's carbon dioxide is stored by trees. As a result of their destruction, carbon dioxide builds up more quickly since there are no trees to absorb it. Additionally, trees release the carbon they stored when we burn them.

Agriculture | Many kinds of greenhouse gases are released into the atmosphere by growing crops and raising livestock. Animals, for instance, create methane, a greenhouse gas that is 30 times more potent than carbon dioxide. The nitrous oxide used in fertilisers is roughly 300 times more strong than carbon dioxide.

How to Prevent Climate Change

We need to look out for drastic steps to stop climate change since it is affecting the resources and life on our planet. We can stop climate change if the right solutions are put in place. Here are some strategies for reducing climate change:

Raising public awareness of climate change

Prohibiting tree-cutting and deforestation.

Ensure the surroundings are clean.

Refrain from using chemical fertilisers.

Water and other natural resource waste should be reduced.

Protect the animals and plants.

Purchase energy-efficient goods and equipment.

Increase the number of trees in the neighbourhood and its surroundings.

Follow the law and safeguard the environment's resources.

Reduce the amount of energy you use.

During the last few decades especially, climate change has grown to be of concern. Global concern has been raised over changes in the Earth's climatic pattern. The causes of climate change are numerous, as well as the effects of it and it is our responsibility as inhabitants of this planet to look after its well being and leave it in a better condition for future generations.

What Is Climate Change?

Climate change refers to long-term shifts in temperatures and weather patterns. Such shifts can be natural, due to changes in the sun’s activity or large volcanic eruptions. But since the 1800s, human activities have been the main driver of climate change , primarily due to the burning of fossil fuels like coal, oil and gas.

Burning fossil fuels generates greenhouse gas emissions that act like a blanket wrapped around the Earth, trapping the sun’s heat and raising temperatures.

The main greenhouse gases that are causing climate change include carbon dioxide and methane. These come from using gasoline for driving a car or coal for heating a building, for example. Clearing land and cutting down forests can also release carbon dioxide. Agriculture, oil and gas operations are major sources of methane emissions. Energy, industry, transport, buildings, agriculture and land use are among the main sectors  causing greenhouse gases.

Illustration reads: $90 Trillion for infrastructure by 2030

Humans are responsible for global warming

Climate scientists have showed that humans are responsible for virtually all global heating over the last 200 years. Human activities like the ones mentioned above are causing greenhouse gases that are warming the world faster than at any time in at least the last two thousand years.

The average temperature of the Earth’s surface is now about 1.2°C warmer than it was in the late 1800s (before the industrial revolution) and warmer than at any time in the last 100,000 years. The last decade (2011-2020) was the warmest on record , and each of the last four decades has been warmer than any previous decade since 1850.

Many people think climate change mainly means warmer temperatures. But temperature rise is only the beginning of the story. Because the Earth is a system, where everything is connected, changes in one area can influence changes in all others.

The consequences of climate change now include, among others, intense droughts, water scarcity, severe fires, rising sea levels, flooding, melting polar ice, catastrophic storms and declining biodiversity.

The Earth is asking for help.

People are experiencing climate change in diverse ways

Climate change can affect our health , ability to grow food, housing, safety and work. Some of us are already more vulnerable to climate impacts, such as people living in small island nations and other developing countries. Conditions like sea-level rise and saltwater intrusion have advanced to the point where whole communities have had to relocate, and protracted droughts are putting people at risk of famine. In the future, the number of people displaced by weather-related events is expected to rise.

Every increase in global warming matters

In a series of UN reports , thousands of scientists and government reviewers agreed that limiting global temperature rise to no more than 1.5°C would help us avoid the worst climate impacts and maintain a livable climate. Yet policies currently in place point to a 3°C temperature rise by the end of the century.

The emissions that cause climate change come from every part of the world and affect everyone, but some countries produce much more than others .The seven biggest emitters alone (China, the United States of America, India, the European Union, Indonesia, the Russian Federation, and Brazil) accounted for about half of all global greenhouse gas emissions in 2020.

Everyone must take climate action, but people and countries creating more of the problem have a greater responsibility to act first.

Photocomposition: an image of the world globe looking worried to a thermometer with raising temperatures

We face a huge challenge but already know many solutions

Many climate change solutions can deliver economic benefits while improving our lives and protecting the environment. We also have global frameworks and agreements to guide progress, such as the Sustainable Development Goals , the UN Framework Convention on Climate Change and the Paris Agreement . Three broad categories of action are: cutting emissions, adapting to climate impacts and financing required adjustments.

Switching energy systems from fossil fuels to renewables like solar or wind will reduce the emissions driving climate change. But we have to act now. While a growing number of countries is committing to net zero emissions by 2050, emissions must be cut in half by 2030 to keep warming below 1.5°C. Achieving this means huge declines in the use of coal, oil and gas: over two-thirds of today’s proven reserves of fossil fuels need to be kept in the ground by 2050 in order to prevent catastrophic levels of climate change.

Growing coalition

Adapting to climate consequences protects people, homes, businesses, livelihoods, infrastructure and natural ecosystems. It covers current impacts and those likely in the future. Adaptation will be required everywhere, but must be prioritized now for the most vulnerable people with the fewest resources to cope with climate hazards. The rate of return can be high. Early warning systems for disasters, for instance, save lives and property, and can deliver benefits up to 10 times the initial cost.

We can pay the bill now, or pay dearly in the future

Climate action requires significant financial investments by governments and businesses. But climate inaction is vastly more expensive. One critical step is for industrialized countries to fulfil their commitment to provide $100 billion a year to developing countries so they can adapt and move towards greener economies.

Responding to the Climate Threat: Essays on Humanity’s Greatest Challenge

Responding to the Climate Threat: Essays on Humanity’s Greatest Challenge

A new book co-authored by MIT Joint Program Founding Co-Director Emeritus Henry Jacoby

From the Back Cover

This book demonstrates how robust and evolving science can be relevant to public discourse about climate policy. Fighting climate change is the ultimate societal challenge, and the difficulty is not just in the wrenching adjustments required to cut greenhouse emissions and to respond to change already under way. A second and equally important difficulty is ensuring widespread public understanding of the natural and social science. This understanding is essential for an effective risk management strategy at a planetary scale. The scientific, economic, and policy aspects of climate change are already a challenge to communicate, without factoring in the distractions and deflections from organized programs of misinformation and denial. 

Here, four scholars, each with decades of research on the climate threat, take on the task of explaining our current understanding of the climate threat and what can be done about it, in lay language―importantly, without losing critical  aspects of the natural and social science. In a series of essays, published during the 2020 presidential election, the COVID pandemic, and through the fall of 2021, they explain the essential components of the challenge, countering the forces of distrust of the science and opposition to a vigorous national response.  

Each of the essays provides an opportunity to learn about a particular aspect of climate science and policy within the complex context of current events. The overall volume is more than the sum of its individual articles. Proceeding each essay is an explanation of the context in which it was written, followed by observation of what has happened since its first publication. In addition to its discussion of topical issues in modern climate science, the book also explores science communication to a broad audience. Its authors are not only scientists – they are also teachers, using current events to teach when people are listening. For preserving Earth’s planetary life support system, science and teaching are essential. Advancing both is an unending task.

[Leer en español aquí]

The scientific consensus that climate change is happening and that it is human-caused is strong. Scientific investigation of global warming began in the 19th century , and by the early 2000s, this research began to coalesce into confidence about the reality, causes, and general range of adverse effects of global warming. This conclusion was drawn from studying air and ocean temperatures, the atmosphere’s composition, satellite records, ice cores, modeling, and more.

In 1988 the United Nations and World Meteorological Organization founded the Intergovernmental Panel on Climate Change, IPCC, to provide regular updates on the scientific evidence on global warming. In a 2013 report , the IPCC concluded that scientific evidence of warming is “unequivocal” and that the largest cause is an increase of carbon dioxide in the atmosphere as a result of humans burning fossil fuels. The IPCC continues to assess this science, periodically issuing new reports.

Climate change is real and caused by humans

The IPCC is not the only scientific group that has reached a clear consensus on the scientific evidence of human-caused global warming. As this NASA page points out, 200 global scientific organizations, 11 international science academies, and 18 American science associations have released statements in alignment with this consensus.

Amanda Staudt is the senior director for climate, atmospheric and polar sciences at the National Academies of Science, Engineering and Medicine, where she has worked since 2001. The Academies, she said, first began studying climate change in 1979, researching how much warming would likely happen if the amount of carbon dioxide concentrations in the atmosphere were doubled.

Four decades later, those findings have held up and have been strengthened based on scores of continued studies and analysis. “The remarkable thing about that study,” she said, “is that they basically got the right answer” from the start. This 1979 study by the National Research Council, Staudt said, led to investment in climate science in the U.S.

Though this consensus has been thoroughly established, scientific research and new findings continue. Staudt said countless attempted rebuttals of climate science findings have been researched and disproved.

“We did a lot of studies in that time period, looking at those questions,” she said, ”and one by one, putting them to bed and convincing ourselves over and over again, that humans were affecting climate, and that we could document that effect.”

At the National Academies, reaching consensus requires open sessions and dialogue with scientists and agreement from committees, which typically consist of 12-15 experts. Their draft reports go through peer review, and reviewers’ concerns are resolved before publication is approved. The goal is for the complex science of climate change to become as thoroughly researched and substantiated as possible.

“One of the things I think about scientists is that we’re all inherently skeptics at some level,” Staudt said. “That’s what drives us to science, that we have questions about the world around us. And we want to prove that for ourselves.”

Scientists consistently reaffirm evidence that climate change is happening

Climate scientists worldwide go through similar processes before their findings are published. And their research papers, too, show a strong consensus about global warming. As NASA states on its website , “Multiple studies published in peer-reviewed scientific journals show that 97 percent or more of actively publishing climate scientists agree: Climate-warming trends over the past century are extremely likely due to human activities.” (By sound practice, scientists resist saying science is for all times “certain” or that its findings are “final,” and the “extremely likely” language respects that practice.)

One of the studies about the consensus was led by John Cook, a fellow at the Climate Change Communication Research Hub at Monash University in Melbourne, Australia. Cook and colleagues reviewed nearly 12,000 scientific papers to examine how aligned published research is on major findings on climate change. That study found that 97 percent of scholarly papers that take a position on climate change do endorse the consensus. The papers that rejected the consensus position contained errors, according to subsequent research .

In reviewing the papers, Cook has said he and his colleagues found the consensus to have been so widely accepted by 2013 that many researchers by then no longer felt a need to mention or reaffirm it in their research papers.

What Are the Causes of Climate Change?

We can’t fight climate change without understanding what drives it.

At the root of climate change is the phenomenon known as the greenhouse effect , the term scientists use to describe the way that certain atmospheric gases “trap” heat that would otherwise radiate upward, from the planet’s surface, into outer space. On the one hand, we have the greenhouse effect to thank for the presence of life on earth; without it, our planet would be cold and unlivable.

But beginning in the mid- to late-19th century, human activity began pushing the greenhouse effect to new levels. The result? A planet that’s warmer right now than at any other point in human history, and getting ever warmer. This global warming has, in turn, dramatically altered natural cycles and weather patterns, with impacts that include extreme heat, protracted drought, increased flooding, more intense storms, and rising sea levels. Taken together, these miserable and sometimes deadly effects are what have come to be known as climate change .

Detailing and discussing the human causes of climate change isn’t about shaming people, or trying to make them feel guilty for their choices. It’s about defining the problem so that we can arrive at effective solutions. And we must honestly address its origins—even though it can sometimes be difficult, or even uncomfortable, to do so. Human civilization has made extraordinary productivity leaps, some of which have led to our currently overheated planet. But by harnessing that same ability to innovate and attaching it to a renewed sense of shared responsibility, we can find ways to cool the planet down, fight climate change , and chart a course toward a more just, equitable, and sustainable future.

Here’s a rough breakdown of the factors that are driving climate change.

Natural causes of climate change

Human-driven causes of climate change, transportation, electricity generation, industry & manufacturing, agriculture, oil & gas development, deforestation, our lifestyle choices.

Some amount of climate change can be attributed to natural phenomena. Over the course of Earth’s existence, volcanic eruptions , fluctuations in solar radiation , tectonic shifts , and even small changes in our orbit have all had observable effects on planetary warming and cooling patterns.

But climate records are able to show that today’s global warming—particularly what has occured since the start of the industrial revolution—is happening much, much faster than ever before. According to NASA , “[t]hese natural causes are still in play today, but their influence is too small or they occur too slowly to explain the rapid warming seen in recent decades.” And the records refute the misinformation that natural causes are the main culprits behind climate change, as some in the fossil fuel industry and conservative think tanks would like us to believe.

Scientists agree that human activity is the primary driver of what we’re seeing now worldwide. (This type of climate change is sometimes referred to as anthropogenic , which is just a way of saying “caused by human beings.”) The unchecked burning of fossil fuels over the past 150 years has drastically increased the presence of atmospheric greenhouse gases, most notably carbon dioxide . At the same time, logging and development have led to the widespread destruction of forests, wetlands, and other carbon sinks —natural resources that store carbon dioxide and prevent it from being released into the atmosphere.

Right now, atmospheric concentrations of greenhouse gases like carbon dioxide, methane , and nitrous oxide are the highest they’ve been in the last 800,000 years . Some greenhouse gases, like hydrochlorofluorocarbons (HFCs) , do not even exist in nature. By continuously pumping these gases into the air, we helped raise the earth’s average temperature by about 1.9 degrees Fahrenheit during the 20th century—which has brought us to our current era of deadly, and increasingly routine, weather extremes. And it’s important to note that while climate change affects everyone in some way, it doesn’t do so equally: All over the world, people of color and those living in economically disadvantaged or politically marginalized communities bear a much larger burden , despite the fact that these communities play a much smaller role in warming the planet.

Our ways of generating power for electricity, heat, and transportation, our built environment and industries, our ways of interacting with the land, and our consumption habits together serve as the primary drivers of climate change. While the percentages of greenhouse gases stemming from each source may fluctuate, the sources themselves remain relatively consistent.

The cars, trucks, ships, and planes that we use to transport ourselves and our goods are a major source of global greenhouse gas emissions. (In the United States, they actually constitute the single-largest source.) Burning petroleum-based fuel in combustion engines releases massive amounts of carbon dioxide into the atmosphere. Passenger cars account for 41 percent of those emissions, with the typical passenger vehicle emitting about 4.6 metric tons of carbon dioxide per year. And trucks are by far the worst polluters on the road. They run almost constantly and largely burn diesel fuel, which is why, despite accounting for just 4 percent of U.S. vehicles, trucks emit 23 percent of all greenhouse gas emissions from transportation.

We can get these numbers down, but we need large-scale investments to get more zero-emission vehicles on the road and increase access to reliable public transit .

As of 2021, nearly 60 percent of the electricity used in the United States comes from the burning of coal, natural gas , and other fossil fuels . Because of the electricity sector’s historical investment in these dirty energy sources, it accounts for roughly a quarter of U.S. greenhouse gas emissions, including carbon dioxide, methane, and nitrous oxide.

That history is undergoing a major change, however: As renewable energy sources like wind and solar become cheaper and easier to develop, utilities are turning to them more frequently. The percentage of clean, renewable energy is growing every year—and with that growth comes a corresponding decrease in pollutants.

But while things are moving in the right direction, they’re not moving fast enough. If we’re to keep the earth’s average temperature from rising more than 1.5 degrees Celsius, which scientists say we must do in order to avoid the very worst impacts of climate change, we have to take every available opportunity to speed up the shift from fossil fuels to renewables in the electricity sector.

A graphic titled "Total U.S. Greenhouse Gas Emissions by Economic Sector (2020)"

The factories and facilities that produce our goods are significant sources of greenhouse gases; in 2020, they were responsible for fully 24 percent of U.S. emissions. Most industrial emissions come from the production of a small set of carbon-intensive products, including basic chemicals, iron and steel, cement and concrete, aluminum, glass, and paper. To manufacture the building blocks of our infrastructure and the vast array of products demanded by consumers, producers must burn through massive amounts of energy. In addition, older facilities in need of efficiency upgrades frequently leak these gases, along with other harmful forms of air pollution .

One way to reduce the industrial sector’s carbon footprint is to increase efficiency through improved technology and stronger enforcement of pollution regulations. Another way is to rethink our attitudes toward consumption (particularly when it comes to plastics ), recycling , and reuse —so that we don’t need to be producing so many things in the first place. And, since major infrastructure projects rely heavily on industries like cement manufacturing (responsible for 7 percent of annual global greenhouse gas), policy mandates must leverage the government’s purchasing power to grow markets for cleaner alternatives, and ensure that state and federal agencies procure more sustainably produced materials for these projects. Hastening the switch from fossil fuels to renewables will also go a long way toward cleaning up this energy-intensive sector.

The advent of modern, industrialized agriculture has significantly altered the vital but delicate relationship between soil and the climate—so much so that agriculture accounted for 11 percent of U.S. greenhouse gas emissions in 2020. This sector is especially notorious for giving off large amounts of nitrous oxide and methane, powerful gases that are highly effective at trapping heat. The widespread adoption of chemical fertilizers , combined with certain crop-management practices that prioritize high yields over soil health, means that agriculture accounts for nearly three-quarters of the nitrous oxide found in our atmosphere. Meanwhile, large-scale industrialized livestock production continues to be a significant source of atmospheric methane, which is emitted as a function of the digestive processes of cattle and other ruminants.

But farmers and ranchers—especially Indigenous farmers, who have been tending the land according to sustainable principles —are reminding us that there’s more than one way to feed the world. By adopting the philosophies and methods associated with regenerative agriculture , we can slash emissions from this sector while boosting our soil’s capacity for sequestering carbon from the atmosphere, and producing healthier foods.

Oil and gas lead to emissions at every stage of their production and consumption—not only when they’re burned as fuel, but just as soon as we drill a hole in the ground to begin extracting them. Fossil fuel development is a major source of methane, which invariably leaks from oil and gas operations : drilling, fracking , transporting, and refining. And while methane isn’t as prevalent a greenhouse gas as carbon dioxide, it’s many times more potent at trapping heat during the first 20 years of its release into the atmosphere. Even abandoned and inoperative wells—sometimes known as “orphaned” wells —leak methane. More than 3 million of these old, defunct wells are spread across the country and were responsible for emitting more than 280,000 metric tons of methane in 2018.

Unsurprisingly, given how much time we spend inside of them, our buildings—both residential and commercial—emit a lot of greenhouse gases. Heating, cooling, cooking, running appliances, and maintaining other building-wide systems accounted for 13 percent of U.S. emissions overall in 2020. And even worse, some 30 percent of the energy used in U.S. buildings goes to waste, on average.

Every day, great strides are being made in energy efficiency , allowing us to achieve the same (or even better) results with less energy expended. By requiring all new buildings to employ the highest efficiency standards—and by retrofitting existing buildings with the most up-to-date technologies—we’ll reduce emissions in this sector while simultaneously making it easier and cheaper for people in all communities to heat, cool, and power their homes: a top goal of the environmental justice movement.

Another way we’re injecting more greenhouse gas into the atmosphere is through the clearcutting of the world’s forests and the degradation of its wetlands . Vegetation and soil store carbon by keeping it at ground level or underground. Through logging and other forms of development, we’re cutting down or digging up vegetative biomass and releasing all of its stored carbon into the air. In Canada’s boreal forest alone, clearcutting is responsible for releasing more than 25 million metric tons of carbon dioxide into the atmosphere each year—the emissions equivalent of 5.5 million vehicles.

Government policies that emphasize sustainable practices, combined with shifts in consumer behavior , are needed to offset this dynamic and restore the planet’s carbon sinks .

The decisions we make every day as individuals—which products we purchase, how much electricity we consume, how we get around, what we eat (and what we don’t—food waste makes up 4 percent of total U.S. greenhouse gas emissions)—add up to our single, unique carbon footprints . Put all of them together and you end up with humanity’s collective carbon footprint. The first step in reducing it is for us to acknowledge the uneven distribution of climate change’s causes and effects, and for those who bear the greatest responsibility for global greenhouse gas emissions to slash them without bringing further harm to those who are least responsible .

The big, climate-affecting decisions made by utilities, industries, and governments are shaped, in the end, by us : our needs, our demands, our priorities. Winning the fight against climate change will require us to rethink those needs, ramp up those demands , and reset those priorities. Short-term thinking of the sort that enriches corporations must give way to long-term planning that strengthens communities and secures the health and safety of all people. And our definition of climate advocacy must go beyond slogans and move, swiftly, into the realm of collective action—fueled by righteous anger, perhaps, but guided by faith in science and in our ability to change the world for the better.

If our activity has brought us to this dangerous point in human history, breaking old patterns can help us find a way out.

What is climate change mitigation and why is it urgent?

  • Climate change mitigation involves actions to reduce or prevent greenhouse gas emissions from human activities.
  • Mitigation efforts include transitioning to renewable energy sources, enhancing energy efficiency, adopting regenerative agricultural practices and protecting and restoring forests and critical ecosystems.
  • Effective mitigation requires a whole-of-society approach and structural transformations to reduce emissions and limit global warming to 1.5°C above pre-industrial levels.
  • International cooperation, for example through the Paris Agreement, is crucial in guiding and achieving global and national mitigation goals.
  • Mitigation efforts face challenges such as the world's deep-rooted dependency on fossil fuels, the increased demand for new mineral resources and the difficulties in revamping our food systems.
  • These challenges also offer opportunities to improve resilience and contribute to sustainable development.

What is climate change mitigation?

Climate change mitigation refers to any action taken by governments, businesses or people to reduce or prevent greenhouse gases, or to enhance carbon sinks that remove them from the atmosphere. These gases trap heat from the sun in our planet’s atmosphere, keeping it warm. 

Since the industrial era began, human activities have led to the release of dangerous levels of greenhouse gases, causing global warming and climate change. However, despite unequivocal research about the impact of our activities on the planet’s climate and growing awareness of the severe danger climate change poses to our societies, greenhouse gas emissions keep rising. If we can slow down the rise in greenhouse gases, we can slow down the pace of climate change and avoid its worst consequences.

Reducing greenhouse gases can be achieved by:

  • Shifting away from fossil fuels : Fossil fuels are the biggest source of greenhouse gases, so transitioning to modern renewable energy sources like solar, wind and geothermal power, and advancing sustainable modes of transportation, is crucial.
  • Improving energy efficiency : Using less energy overall – in buildings, industries, public and private spaces, energy generation and transmission, and transportation – helps reduce emissions. This can be achieved by using thermal comfort standards, better insulation and energy efficient appliances, and by improving building design, energy transmission systems and vehicles.
  • Changing agricultural practices : Certain farming methods release high amounts of methane and nitrous oxide, which are potent greenhouse gases. Regenerative agricultural practices – including enhancing soil health, reducing livestock-related emissions, direct seeding techniques and using cover crops – support mitigation, improve resilience and decrease the cost burden on farmers.
  • The sustainable management and conservation of forests : Forests act as carbon sinks , absorbing carbon dioxide and reducing the overall concentration of greenhouse gases in the atmosphere. Measures to reduce deforestation and forest degradation are key for climate mitigation and generate multiple additional benefits such as biodiversity conservation and improved water cycles.
  • Restoring and conserving critical ecosystems : In addition to forests, ecosystems such as wetlands, peatlands, and grasslands, as well as coastal biomes such as mangrove forests, also contribute significantly to carbon sequestration, while supporting biodiversity and enhancing climate resilience.
  • Creating a supportive environment : Investments, policies and regulations that encourage emission reductions, such as incentives, carbon pricing and limits on emissions from key sectors are crucial to driving climate change mitigation.

What is the 1.5°C goal and why do we need to stick to it?

In 2015, 196 Parties to the UN Climate Convention in Paris adopted the Paris Agreement , a landmark international treaty, aimed at curbing global warming and addressing the effects of climate change. Its core ambition is to cap the rise in global average temperatures to well below 2°C above levels observed prior to the industrial era, while pursuing efforts to limit the increase to 1.5°C.

The 1.5°C goal is extremely important, especially for vulnerable communities already experiencing severe climate change impacts. Limiting warming below 1.5°C will translate into less extreme weather events and sea level rise, less stress on food production and water access, less biodiversity and ecosystem loss, and a lower chance of irreversible climate consequences.

To limit global warming to the critical threshold of 1.5°C, it is imperative for the world to undertake significant mitigation action. This requires a reduction in greenhouse gas emissions by 45 percent before 2030 and achieving net-zero emissions by mid-century.

What are the policy instruments that countries can use to drive mitigation?

Everyone has a role to play in climate change mitigation, from individuals adopting sustainable habits and advocating for change to governments implementing regulations, providing incentives and facilitating investments. The private sector, particularly those businesses and companies responsible for causing high emissions, should take a leading role in innovating, funding and driving climate change mitigation solutions. 

International collaboration and technology transfer is also crucial given the global nature and size of the challenge. As the main platform for international cooperation on climate action, the Paris Agreement has set forth a series of responsibilities and policy tools for its signatories. One of the primary instruments for achieving the goals of the treaty is Nationally Determined Contributions (NDCs) . These are the national climate pledges that each Party is required to develop and update every five years. NDCs articulate how each country will contribute to reducing greenhouse gas emissions and enhance climate resilience.   While NDCs include short- to medium-term targets, long-term low emission development strategies (LT-LEDS) are policy tools under the Paris Agreement through which countries must show how they plan to achieve carbon neutrality by mid-century. These strategies define a long-term vision that gives coherence and direction to shorter-term national climate targets.

At the same time, the call for climate change mitigation has evolved into a call for reparative action, where high-income countries are urged to rectify past and ongoing contributions to the climate crisis. This approach reflects the UN Framework Convention on Climate Change (UNFCCC) which advocates for climate justice, recognizing the unequal historical responsibility for the climate crisis, emphasizing that wealthier countries, having profited from high-emission activities, bear a greater obligation to lead in mitigating these impacts. This includes not only reducing their own emissions, but also supporting vulnerable countries in their transition to low-emission development pathways.

Another critical aspect is ensuring a just transition for workers and communities that depend on the fossil fuel industry and its many connected industries. This process must prioritize social equity and create alternative employment opportunities as part of the shift towards renewable energy and more sustainable practices.

For emerging economies, innovation and advancements in technology have now demonstrated that robust economic growth can be achieved with clean, sustainable energy sources. By integrating renewable energy technologies such as solar, wind and geothermal power into their growth strategies, these economies can reduce their emissions, enhance energy security and create new economic opportunities and jobs. This shift not only contributes to global mitigation efforts but also sets a precedent for sustainable development.

What are some of the challenges slowing down climate change mitigation efforts?

Mitigating climate change is fraught with complexities, including the global economy's deep-rooted dependency on fossil fuels and the accompanying challenge of eliminating fossil fuel subsidies. This reliance – and the vested interests that have a stake in maintaining it – presents a significant barrier to transitioning to sustainable energy sources.

The shift towards decarbonization and renewable energy is driving increased demand for critical minerals such as copper, lithium, nickel, cobalt, and rare earth metals. Since new mining projects can take up to 15 years to yield output, mineral supply chains could become a bottleneck for decarbonization efforts. In addition, these minerals are predominantly found in a few, mostly low-income countries, which could heighten supply chain vulnerabilities and geopolitical tensions.

Furthermore, due to the significant demand for these minerals and the urgency of the energy transition, the scaled-up investment in the sector has the potential to exacerbate environmental degradation, economic and governance risks, and social inequalities, affecting the rights of Indigenous Peoples, local communities, and workers. Addressing these concerns necessitates implementing social and environmental safeguards, embracing circular economy principles, and establishing and enforcing responsible policies and regulations .

Agriculture is currently the largest driver of deforestation worldwide. A transformation in our food systems to reverse the impact that agriculture has on forests and biodiversity is undoubtedly a complex challenge. But it is also an important opportunity. The latest IPCC report highlights that adaptation and mitigation options related to land, water and food offer the greatest potential in responding to the climate crisis. Shifting to regenerative agricultural practices will not only ensure a healthy, fair and stable food supply for the world’s population, but also help to significantly reduce greenhouse gas emissions.

What are some examples of climate change mitigation?

In Mauritius , UNDP, with funding from the Green Climate Fund, has supported the government to install battery energy storage capacity that has enabled 50 MW of intermittent renewable energy to be connected to the grid, helping to avoid 81,000 tonnes of carbon dioxide annually. 

In Indonesia , UNDP has been working with the government for over a decade to support sustainable palm oil production. In 2019, the country adopted a National Action Plan on Sustainable Palm Oil, which was collaboratively developed by government, industry and civil society representatives. The plan increased the adoption of practices to minimize the adverse social and environmental effects of palm oil production and to protect forests. Since 2015, 37 million tonnes of direct greenhouse gas emissions have been avoided and 824,000 hectares of land with high conservation value have been protected.

In Moldova and Paraguay , UNDP has helped set up Green City Labs that are helping build more sustainable cities. This is achieved by implementing urban land use and mobility planning, prioritizing energy efficiency in residential buildings, introducing low-carbon public transport, implementing resource-efficient waste management, and switching to renewable energy sources. 

UNDP has supported the governments of Brazil, Costa Rica, Ecuador and Indonesia to implement results-based payments through the REDD+ (Reducing emissions from deforestation and forest degradation in developing countries) framework. These include payments for environmental services and community forest management programmes that channel international climate finance resources to local actors on the ground, specifically forest communities and Indigenous Peoples. 

UNDP is also supporting small island developing states like the Comoros to invest in renewable energy and sustainable infrastructure. Through the Africa Minigrids Program , solar minigrids will be installed in two priority communities, Grand Comore and Moheli, providing energy access through distributed renewable energy solutions to those hardest to reach.

And in South Africa , a UNDP initative to boost energy efficiency awareness among the general population and improve labelling standards has taken over commercial shopping malls.

What is climate change mitigation and why is it urgent?

What is UNDP’s role in supporting climate change mitigation?

UNDP aims to assist countries with their climate change mitigation efforts, guiding them towards sustainable, low-carbon and climate-resilient development. This support is in line with achieving the Sustainable Development Goals (SDGs), particularly those related to affordable and clean energy (SDG7), sustainable cities and communities (SDG11), and climate action (SDG13). Specifically, UNDP’s offer of support includes developing and improving legislation and policy, standards and regulations, capacity building, knowledge dissemination, and financial mobilization for countries to pilot and scale-up mitigation solutions such as renewable energy projects, energy efficiency initiatives and sustainable land-use practices. 

With financial support from the Global Environment Facility and the Green Climate Fund, UNDP has an active portfolio of 94 climate change mitigation projects in 69 countries. These initiatives are not only aimed at reducing greenhouse gas emissions, but also at contributing to sustainable and resilient development pathways.

Investigating the Impacts of Climate Change on National Park Ecosystems and What Students Can Do to Help

Every person who has ever visited a national park absolutely loves them. Each national park is an incredible standard of perseverance and trepidation in the eternal struggle to preserve nature. National parks are beautiful and outstanding; they allow every tourist to breathe the air of pristine nature and feel the vibes of untouched wilderness. You should do it next weekend if you’ve never visited a national park. We all need a breath of fresh air and an escape from city fatigue occasionally. 

However, national parks are in danger. Global climate change affects each park’s ecosystem, and the devastating consequences become more noticeable yearly. Humanity loses the battle for preserving nature, and in today’s environment, every vote counts. Every student can contribute to the fight against climate change and global warming; there are several ways to help the single voice make a difference. 

You can start small: write academic papers on ecological topics, practice and promote waste management among friends and relatives, and join environmental activist communities. If you need more free time, consider letting expert services fulfill the “ write my essay ” request and provide necessary assistance with academic assignments. 

The Destructive Influence of Climate Change on National Park Ecosystems

Yosemite national park.

One of the most essential locations in the Sierra Nevada is already feeling the effects of climate change. Over the past few years, Yosemite National Park has been closed multiple times due to heat waves, devastating wildfires, and unhealthy air quality caused by smoke from these fires. By the end of the century, Yosemite’s average temperature might rise by 10 degrees Fahrenheit, which is far more than the expected climb in world temperatures.

Less snow, dried-up waterfalls, more fires, and more tree die-offs like the ones Dickman saw are all things that park rangers and scientists have noticed. The average temperature directly correlates to the maximum height at which trees can grow. Research has also shown that, due to the area’s warming over the past century, the range of small mammals in Yosemite has moved uphill.

Glacier National Park

Some of Montana Park’s 26 glaciers have shrunk by as much as 80% in the last half-century. The melting glaciers greatly threaten the aquatic habitats within the park that depend on cold waters. Additionally, they raise the risk of floods in nearby areas. 

The climate catastrophe is anticipated to cause further flooding at Glacier, similar to the June floods at Yellowstone. At the same time, Yellowstone was closed to the public due to the devastating flooding, so officials in Glacier National Park issued a similar warning. Another major contributor to rising sea levels is glacier melting. Glacier National Park’s glaciers are few, but in the context of a warming globe, their combined melting will be sufficient to generate substantial global sea level rise.

Sequoia National Park

The megadrought in the West is eroding and killing the country’s most extensive and oldest trees in Sequoia National Park, located just south of Yosemite Valley in California. According to the National Park Service, more than 85% of the giant sequoia grove land across the broader Sierra Nevada was destroyed in six years of fires , an increase from roughly 25% over the previous 100 years. 

Officials closed Sequoia and Kings Canyon National Parks to the public and took drastic measures to protect the trees after three of those flames crossed into the parks. Scientists have already witnessed the “major effects” of climate change, which primarily manifest as hotter and drier droughts that ignite devastating wildfires.

How Students Can Help in the Global Struggle Against Climate Change

Conserve energy and water .

Reduce water and energy use around the house and in the classroom. When not in use, switch off lights and electronics and use those with energy-saving features. Cutting back on shower time, removing the water supply while brushing your teeth, and repairing any leaks are all great ways to reduce water usage. Suggest that your institution implement strategies to reduce its water and energy consumption. 

Promote Waste Management 

Personal waste management is the simplest and most effective way to contribute to the global environmental fight. There is no need to doubt the significance of your contribution because waste management is a significant and valuable initiative. 

Start with yourself and always segregate waste as diligently as possible, even if it takes a little longer. Learn the theoretical basis and tell others about the importance of waste management. If you convey the importance of waste sorting to at least a few people, then this will already be a colossal contribution in the long term.

Support Eco-Friendly Initiatives 

Join a school or neighborhood group that focuses on environmental issues, such as recycling and conservation. Help out with community green projects like tree planting, cleanups, or anti-single-use plastic efforts. If you don’t see any existing groups actively working to combat climate change, you might want to consider forming one yourself. 

Write Academic Papers on Eco Topics 

You may think that the contribution of such an approach may be negligible and insignificant, but remember that in such an essential matter as preserving our planet, no contribution is too small. Make it a habit to always write papers on environmental topics when the professor allows you to choose the subject yourself. If you write high-quality papers and raise exciting topics, your arguments have a chance to interest readers. If at least a few people think about the issues you raised after reading your essay, then you have not written your paper in vain. 

In addition, environmental topics are a fertile topic for writing a high-quality paper, as they allow you to write a complex, structured essay with many implications and meanings. To add depth to your essay, you can always contextualize global economic problems and different perspectives on how to solve them.

Educate and Inspire Others 

Tell everyone you know about the impacts of climate change and what you’ve learned about the topic. Get them on board with sustainable practices and green projects just like you are. Keep in mind that you, the student, can make a difference with your small but significant efforts. By implementing these habits and encouraging others to do the same, you can aid in the fight against climate change and build a better, more sustainable future for everyone.

It’s Not Your Imagination. Your Allergies Are Getting Worse.

A photograph of a cloud of pollen being released from the cones of a pine tree.

By Margaret Renkl

Ms. Renkl is a contributing Opinion writer who covers flora, fauna, politics and culture in the American South.

It’s spring, and I love spring more than I love almost anything else about the natural world, but I don’t love the pollen. My eyes itch. My nose is stopped up. First thing in the morning I sneeze. Last thing at night I sneeze. My husband turns away from me to sleep because the pollen grains clinging to my hair make him sneeze, too.

I was never prone to seasonal allergies before I moved to Middle Tennessee, which is not even one of the 10 most challenging places for allergy sufferers in this country. I am now up to three over-the-counter medications a day, and I have developed a tiny dependence on Fisherman’s Friend lozenges, which work a bit like the Vicks VapoRub of my childhood memories. Vicks is still around — the comedian Wanda Sykes has a wonderful bit about it — but Fisherman’s Friend doesn’t announce my presence in advance the way Vicks would.

I also drink gallons of an herbal tea labeled “congestion relief,” though I no longer believe that relief is possible. The hill of spring allergies, which in Middle Tennessee used to be on the downslope by now, has become an all-year mountain, with tree pollen and grass pollen and ragweed pollen rolling together in great clouds from late February right up till Thanksgiving.

But it’s worse in spring. I can stand at my back door and watch a white pine like this one sending out waves of pollen that remind me of the crop-duster scene in “North by Northwest.” In spring, my glasses are coated with pollen outside and in. In spring, my little red Nissan Leaf looks like a little orange Leaf, and the gray boards of our back deck look as though they’ve grown a coating of new moss.

The only relief for any of it is a good soaking rain, but the reprieve of rain is only temporary. Increased rainfall prolongs the blooming season of many trees, grasses and other plants. (Most wildflowers are pollinated by insects and therefore aren’t prime allergy-inducers, but some, like ragweed, are wind-pollinated, which means they literally throw their pollen to the winds — and into human faces.) A prolonged blooming season in turn allows plants to produce more pollen.

Seasonal allergies are nothing new, but they’ve been worsening as the climate grows warmer. The growing season starts earlier now — in North America an average of 20 days earlier — and lasts longer, too, extending the length of time when plants are pumping pollen into the air. And the resulting misery arises not just because there’s more pollen to breathe in or because it’s around for increasingly longer seasons . At least one study has indicated that the more carbon there is in the air, the more potent the pollen itself is .

Hay fever kicks in when the immune system isn’t able to distinguish between a genuine threat (like a virus) and particles like pollen that are harmless. That’s why adults can develop seasonal allergies when they move to a new region and encounter pollens their immune system doesn’t recognize. Now, thanks to climate change, you don’t even need to move: The warmer climate is shifting growing zones northward, allowing plants to extend their natural range .

In human beings, this all adds up to seasonal allergies that are more widespread and more severe , and it’s only going to get worse: One study predicts a 200 percent increase in pollen production by the end of this century. “In 2018, 7.7 percent of American adults experienced ‘hay fever,’” noted the science journalist Yasmin Tayag in The Atlantic last year. “By 2021, that proportion had risen to about a quarter.” The article is titled “ There Is No Stopping the Allergy Apocalypse .”

Weighed against true climate calamities like deadly heat waves and inundated coastal communities, hay fever may seem like little more than an inconvenience. What’s a few weeks — even months — of itchy eyes and runny noses compared with the global population migrations that are coming? But allergies aren’t mere irritants.

Someone who is suffering from seasonal allergies may be less able to exercise, more vulnerable to infection, less productive at work (if not actually absent), more likely to require treatment in an emergency room. Seasonal allergies have been linked to an increase in both the prevalence and severity of asthma, which is particularly worrisome for children .

None of this is surprising to anyone who’s paying attention to the way the changing climate affects everything nowadays. Wherever you live, even if you aren’t evacuating to avoid a hurricane, or keeping a go bag by the door in case of a wildfire, or wondering if it’s time to move to higher ground, climate change is now affecting your daily life. It’s making wine taste different , sleep more fitful , air travel more turbulent . It’s making the very air harder to breathe .

Meanwhile, the planet will continue to warm, and plants will continue to produce more pollen, and in more concentrated doses, for a longer period of time each year. People who suffer from seasonal allergies will feel worse, and people who aren’t currently troubled by allergy symptoms may yet find themselves sneezing and rubbing their eyes. As Ms. Tayag points out in her Atlantic article, “At this point, not much can be done to stop it.”

That’s true, but a lot can be done to keep it from getting incomprehensibly worse. In the doom versus optimism debate about the climate, much of the optimism lies in the way technology, shored up by policy and legislation, is rising to the challenge faster and more effectively than we ever imagined it could. “Stunning, record-breaking gains in wind and solar power around the world,” David Geddes of The Times writes, means that “a full 30 percent of global electricity was generated by renewables last year.” The time we have left to change our climate’s devastating trajectory is dwindling, but we are finally beginning to take the steps necessary to change it.

But we are only beginning, and beginnings can be snuffed out. At his Mar-a-Lago resort last month, Donald Trump told a group of oil executives and lobbyists that they should donate $1 billion to his campaign because he plans to reverse Joe Biden’s clean energy policies, among other environmental protections opposed by Big Oil, if he is returned to the White House.

NY must make the electric school bus transition

New York State has mandated that by 2035 all school...

New York State has mandated that by 2035 all school buses in the state be zero-emission, like the electric buses above.

  Credit: Logan Bus Co. Inc.

This guest essay reflects the views of Bella Cockerell, New York organizing manager for Mothers Out Front, and Joseph Ambrosio, chief executive of Unique Electric Solutions Inc., a Holbrook-based company that repowers diesel buses into electric buses.

When New York’s all-electric school bus legislation passed in 2022, environmentalists lauded it as a visionary plan and a victory in the climate fight, while school administrators and parents cheered the health and safety benefits it would provide for the state's more than 2 million children who ride to and from school each day.

In the two years since that groundbreaking legislation passed, questions have been raised about the feasibility — both financially and operationally — of meeting the 2027 deadline for new purchases and the 2035 deadline for the entire fleet.

These concerns are misplaced, and the urgency remains to address the detrimental effects of diesel-powered buses on the environment and our children's health.

Air pollution inside a diesel bus can be as much as 12 times higher than outside the bus. That’s because when a school bus stops at a traffic signal, is stuck in traffic, or pauses to pick up or drop off students, the filthy tailpipe emissions drift back into the cabin for the children and driver to breathe in.

This is a major contributor to the surging asthma epidemic, which is especially prevalent in low-income communities and communities of color. For these children, that means difficulty breathing, regular visits to the emergency room, and missed classes. In fact, asthma affects 10% of children and is the leading cause of school absenteeism in New York, according to the state Department of Health. In the long term, it contributes to poorer learning outcomes, lower earning potential, and chronic health conditions.

Alongside the public health benefits of electric school buses are unquestioned environmental benefits. With the transportation sector making up nearly 30% of statewide greenhouse emissions, transitioning our school bus fleet to electric is crucial to the climate fight.

Fortunately, substantial funding is available right now at the state and federal levels for electric school buses and charging stations, as well as for a pragmatic alternative to purchasing new buses — retrofitting existing gas buses to make them electric. Changing over an entire fleet to electric in one year is not always practical; retrofits can address cost concerns and provide more flexibility for a phased transition.

Funds from New York’s Environmental Bond Act and the state's School Bus Incentive Program are already easing the financial burden on school districts, as are the federal bipartisan Infrastructure Act and the Environmental Protection Agency's Clean School Bus Program. The state incentive program alone can provide up to $171,000 for each electric school bus purchased, which would pay for most of the cost of a repower or nearly 50% of a new electric bus. Enough resources exist for school districts to begin the transition immediately.

Even in rural upstate districts, where bus routes face longer commutes and colder temperatures, electric buses have the juice to make these journeys. In Havre, Montana, for example, a sparsely populated rural county, electric school buses have handled temperatures as low as minus-40 degrees.

With school budget votes taking place next week, the time is now for parents to tell their local school officials that they will not stand by while dirty diesel buses compromise their children’s health.

Starting small and learning as we go are key principles. School districts can begin with just a single bus, gaining valuable insights into the operational and logistical aspects.

As the saying goes, “Start small, but start now.”

This guest essay reflects the views of Bella Cockerell, New York organizing manager for Mothers Out Front, and Joseph Ambrosio, chief executive of Unique Electric Solutions Inc., a Holbrook-based company that repowers diesel buses into electric buses.
