What You'll Learn
Fossil fuels and climate change
Fossil fuels are dead plants and animals that decomposed over millions of years. Heat and pressure from the Earth transform those remains into fossil fuels, like coal, oil, and natural gas, underground. Fossil fuels have been used for more than a century to generate most of the energy required for transport, electricity, and businesses. Even today, fossil fuels serve about 80% of our energy needs.
However, the burning of fossil fuels releases gases like carbon dioxide into the atmosphere, which trap heat and lead to climate change. The more greenhouse gases there are in the atmosphere, the hotter the planet gets. Since humans began using fossil fuels, the concentration of carbon dioxide in the atmosphere has rocketed past 400 parts per million, and the global average temperature has increased by 1.2 °C. The use of fossil fuels is the leading contributor to global warming and has caused local pollution where they are produced and used, with their ongoing use causing lasting harm to the climate of our entire planet.
The fossil fuel industry also requires drilling and mining, which leads to environmental destruction and fragmentation and destruction of critical wildlife habitats. Additionally, coal mining operations wash toxic runoff into streams, rivers, and lakes, and oil spills and leaks during extraction or transportation can pollute drinking water sources and jeopardize entire freshwater or ocean ecosystems. Fossil fuels also emit hazardous air pollutants, including sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury, all of which are harmful to the environment and human health.
To tackle climate change and protect the planet, it is essential to phase out polluting sources of energy like fossil fuels and transition to renewable energy sources such as wind and solar power. While this transition is challenging, it is necessary to ensure a sustainable future for the planet.

The environmental impact of fossil fuel extraction
Fossil fuels, including coal, oil, and natural gas, have a significant impact on the environment and human health. The extraction and use of these fuels result in climate change, air and water pollution, and global warming.
The process of extracting fossil fuels through mining, drilling, and fracking harms the environment and human health. Mining operations for coal often involve washing toxic runoff into streams, rivers, and lakes, and dumping vast amounts of unwanted rock and soil into water bodies. Drilling and fracking operations generate enormous volumes of wastewater, which can be contaminated with heavy metals, radioactive materials, and other pollutants. This wastewater is often stored in open-air pits or underground wells that can leak, contaminating drinking water sources and ecosystems.
Extraction processes also have a significant impact on landscapes and ecosystems. Leasing land for infrastructure and operations can result in the destruction and fragmentation of critical wildlife habitats, as well as the displacement of animals. Strip mining, for example, can involve scraping and blasting entire swaths of terrain, including forests and mountaintops, to access coal or oil deposits.
The burning of fossil fuels is a major contributor to global warming and climate change. When fossil fuels are burned, they emit greenhouse gases, such as carbon dioxide, which trap heat in the Earth's atmosphere. This has led to rising global temperatures, with coal being the single largest source of the increase in global average temperatures. Oil, when burned, releases a significant amount of carbon, accounting for about a third of the world's total carbon emissions. Natural gas, while promoted as a cleaner alternative, still accounts for a fifth of the world's carbon emissions.
Fossil fuel-powered vehicles, such as cars, trucks, and boats, are major contributors to air pollution, emitting poisonous carbon monoxide and nitrogen oxide. These emissions produce smog and contribute to respiratory illnesses for those exposed. Additionally, the combustion of additives in gasoline produces ultra-fine particles and aromatic hydrocarbons, which are linked to cancer. Fossil fuel pollution is responsible for one in five deaths worldwide, with 350,000 premature deaths in the United States in 2018 attributed to fossil fuel-related pollution.
The environmental and health impacts of fossil fuels disproportionately affect communities of color and low-income communities. For example, in "Cancer Alley," a predominantly Black and low-income area in Louisiana, the cancer risk is nearly 50 times higher than the national average due to the proximity of numerous chemical plants and oil refineries.
The transition to cleaner and renewable energy sources is essential to mitigate the environmental and health impacts of fossil fuel extraction and use.

Fossil fuels and air pollution
Fossil fuels, such as coal, oil, and natural gas, have been the primary energy source for over a century, powering our vehicles, businesses, and homes. However, the burning of these fuels releases gases, such as carbon dioxide, that contribute to the greenhouse effect and drive global warming. This has led to rising global temperatures, with fossil fuels responsible for over 0.3°C of the 1°C increase in average global temperatures.
The combustion of fossil fuels also emits harmful pollutants, including nitrogen oxides, which contribute to smog and acid rain. These emissions have severe health impacts, causing respiratory illnesses and contributing to millions of premature deaths worldwide. In 2018, 350,000 premature deaths in the United States were attributed to fossil fuel-related air pollution. The health risks disproportionately affect vulnerable communities, including children, older individuals, low-income groups, and people of color.
The extraction and transportation of fossil fuels also contribute to air pollution. For example, coal mining operations release toxic runoff into waterways and generate enormous volumes of wastewater containing heavy metals and other pollutants. Oil spills during extraction or transportation can devastate ocean ecosystems and harm wildlife, as seen in the 2010 BP Deepwater Horizon spill in the Gulf of Mexico.
To address these issues, a transition to renewable energy sources is essential. While fossil fuel companies have made net-zero emissions pledges, these often overlook the emissions from burned products like gasoline. Phasing out fossil fuels and embracing clean energy alternatives is crucial to mitigate climate change and reduce the health and environmental impacts of air pollution.

Fossil fuels and water pollution
Fossil fuels are dead plants and animals that decomposed over millions of years. Heat and pressure from the Earth transform those remains into fossil fuels, like coal, oil and natural gas, underground. Drilling, mining, and burning fossil fuels are all contributing to environmental destruction.
The environmental impacts of fossil fuels extend beyond air pollution to water pollution. Coal mining operations wash toxic runoff into streams, rivers, and lakes, and dump vast quantities of unwanted rock and soil into streams. Oil spills and leaks during extraction or transportation can also pollute drinking water sources and jeopardize entire freshwater or ocean ecosystems.
Fracking, a method used to extract natural gas, has been linked to groundwater pollution. A study found that in areas with shale gas development, there is 17 times more methane in the drinking water. All drilling, fracking, and mining operations generate enormous volumes of wastewater, which can be laden with heavy metals, radioactive materials, and other pollutants. Industries store this waste in open-air pits or underground wells that can leak or overflow into waterways and contaminate aquifers with pollutants linked to cancer, birth defects, neurological damage, and more.
In addition to the direct pollution caused by fossil fuels, the carbon dioxide released when they are burned traps heat in the atmosphere, leading to climate change and rising global temperatures. This, in turn, leads to extreme weather events, wildfires, and rising sea levels, which can further contaminate water sources.

Fossil fuels and extreme weather
Fossil fuels are dead plants and animals that decomposed over millions of years. Heat and pressure from the Earth transform those remains into fossil fuels, like coal, oil, and natural gas, underground. Drilling and mining for fossil fuels lead to environmental destruction. When burned, fossil fuels release gases like carbon dioxide into the atmosphere, which trap heat and cause global warming.
The burning of fossil fuels is the leading contributor to global warming. Coal-fired power plants generate dangerous mercury emissions, sulfur dioxide emissions (which contribute to acid rain), and soot. Fossil fuel-powered cars, trucks, and boats are the main contributors to poisonous carbon monoxide and nitrogen oxide, which produces smog on hot days and leads to respiratory illnesses.
Rising global temperatures caused by the burning of fossil fuels have increased the likelihood and intensity of extreme weather events. Heatwaves, droughts, and floods have become more frequent and intense due to the influence of fossil fuel-driven climate change. Higher temperatures also lead to drier conditions, causing droughts and water scarcity.
To limit the impact of extreme weather events, it is necessary to reduce the supply and demand of fossil fuels. This involves transitioning to renewable energy sources and improving energy efficiency. Litigation is also being used to hold fossil fuel companies accountable for their impact on climate change and their denial of responsibility.
The effects of extreme weather events caused by climate change disproportionately impact low-income countries and contribute to global economic inequality. It is crucial to address the role of fossil fuels in driving climate change and to take action to mitigate its impacts.
