The combustion of fossil fuels is the leading cause of global warming and climate change. Fossil fuels are responsible for the emission of billions of tons of carbon dioxide into the atmosphere annually, with CO2 concentrations at their highest in 800,000 years. The burning of fossil fuels like coal, oil, and natural gas releases a large amount of carbon dioxide, which is the most important human-produced climate-altering greenhouse gas. Other greenhouse gases like methane and nitrous oxide are also emitted from burning fossil fuels, and these gases have a much higher heat-trapping capacity than carbon dioxide. The Intergovernmental Panel on Climate Change (IPCC) has warned that fossil fuel emissions must be halved within 11 years to limit global warming to 1.5°C above pre-industrial levels. Despite commitments made by governments to reduce carbon emissions, fossil fuel companies continue to be major polluters, and strong action is needed to transition to renewable energy sources and sustainable practices.

What You'll Learn
Fossil fuels are the dominant cause of global warming
The Intergovernmental Panel on Climate Change (IPCC) has found that emissions from fossil fuels are the dominant cause of rising global temperatures. In 2018, 89% of global CO2 emissions were from fossil fuels and industry. Of all fossil fuels, coal has the most significant impact on global warming, responsible for over 0.3C of the 1C increase in global average temperatures. Oil releases a significant amount of carbon when burned, contributing approximately a third of the world's total carbon emissions. Natural gas, often promoted as a cleaner alternative, still accounts for a fifth of the world's carbon emissions.
The burning of fossil fuels has significantly increased the concentration of greenhouse gases in the Earth's atmosphere. Carbon dioxide, methane, and nitrous oxide levels are now higher than at any time in the last 800,000 years. Human activities, particularly the combustion of fossil fuels, have increased atmospheric carbon dioxide concentrations by more than 40% since pre-industrial times. Methane concentrations have more than doubled, and nitrous oxide has increased by 18% in the last century.
The impact of fossil fuels on global warming is not limited to direct emissions. Fossil fuel companies are major polluters, and their products contribute to climate change through various industries. Despite commitments to reduce carbon emissions, such as the Paris Agreement, fossil fuel companies continue to prioritize profit over the environment. For instance, BP spent millions on advertising its low-carbon energy and cleaner natural gas while maintaining high expenditures on oil and gas.
To address global warming, a transition away from fossil fuels is imperative. This includes ending fossil fuel subsidies, adopting renewable energy sources, and implementing sustainable practices. While individual actions are important, collective efforts and policy changes are necessary to create a substantial impact.

Coal is the dirtiest fossil fuel
Fossil fuels are the dominant cause of global warming. In 2018, 89% of global CO2 emissions came from fossil fuels and industry. Among all fossil fuels, coal is the dirtiest. Coal is a solid, carbon-heavy rock that comes in four main varieties: lignite, sub-bituminous, bituminous, and anthracite. Nearly all of the coal burned in the United States is sub-bituminous or bituminous, which are middle-of-the-pack in terms of carbon content and the heat energy they can produce. Coal is responsible for over 0.3 degrees Celsius of the 1-degree increase in global average temperatures, making it the largest single source of global temperature rise.
Coal is the most carbon-intensive fossil fuel we can burn. It emits much more greenhouse gas than other sources—more than a hundred times more than nuclear. The process of extracting coal from the ground is also extremely destructive. Underground mining uses heavy machinery to cut coal from deep underground deposits, while surface mining (also known as strip mining) removes entire layers of soil and rock to access coal deposits below. Strip mining accounts for about two-thirds of coal sourced in the United States. This process destroys critical wildlife habitats and forces animals to compete with existing wildlife for resources in less-than-ideal habitats.
The Intergovernmental Panel on Climate Change (IPCC) has warned that fossil fuel emissions must be halved within 11 years if global warming is to be limited to 1.5 degrees Celsius above pre-industrial levels. In 2015, governments around the world signed the Paris Agreement, committing to reduce carbon emissions. However, fossil fuel companies remain huge polluters, and scientists say we need a mass switch to renewable energy. Fossil fuel advertising often fails to communicate the whole truth about their products, and policymakers must be pressured to create change and protect the planet.
To stop climate change, we must transition away from fossil fuels to nuclear and renewable energy sources. This will not only protect future generations but will also bring huge health benefits for the current one.

Oil releases a third of the world's carbon emissions
The Intergovernmental Panel on Climate Change (IPCC) has found that emissions from fossil fuels are the dominant cause of global warming. In 2018, 89% of global CO2 emissions came from fossil fuels and industry. Oil releases a huge amount of carbon when burned—approximately a third of the world's total carbon emissions.
Oil, along with coal and natural gas, is a fossil fuel. Fossil fuels are formed from the decomposition of buried carbon-based organisms that died millions of years ago. They create carbon-rich deposits that are extracted and burned for energy. They are non-renewable and currently supply around 80% of the world’s energy. They are also used to make plastics, steel, and a huge range of products.
When fossil fuels are burned, they release a large amount of carbon dioxide containing the lighter carbon isotope (12C), which tips the ratio of the two variants in the atmosphere. Carbon dioxide is a greenhouse gas, and greenhouse gases act like a blanket, trapping warmth in the Earth's atmosphere. About 90% of the heat radiated from the Earth's surface is absorbed by greenhouse gases and re-radiated, slowing heat loss to space.
The burning of fossil fuels is not the only human activity that releases carbon dioxide. Deforestation and farming practices also contribute to carbon emissions. However, the production and burning of fossil fuels are major contributors to global carbon emissions. In 2021, an analysis by Richard Heede at the Climate Accountability Institute in the US found that the top 20 fossil fuel companies have contributed to 35% of all energy-related carbon dioxide and methane worldwide, totalling 480 billion tonnes of carbon dioxide equivalent since 1965.
Scientists say that a mass switch to renewable energy sources is necessary to limit global warming.

Natural gas is a fossil fuel
The Intergovernmental Panel on Climate Change (IPCC) has found that emissions from fossil fuels are the dominant cause of global warming. Fossil fuel companies remain huge polluters, producing and selling fossil fuel products while scientists say we need a mass switch to renewable energy and efficiency.
Natural gas is often promoted as a cleaner energy source than coal and oil. However, natural gas is still a fossil fuel and accounts for a fifth of the world’s total carbon emissions. The IPCC warns that fossil fuel emissions must be halved within 11 years if global warming is to be limited to 1.5°C above pre-industrial levels.
Natural gas can be found in underground geological formations, often alongside other fossil fuels like coal and oil. Most natural gas has been created through either biogenic or thermogenic processes. Thermogenic gas takes a much longer period of time to form and is created when organic matter is heated and compressed deep underground. Methanogenic organisms produce methane from a variety of sources, principally carbon dioxide.
The extraction and consumption of natural gas is a major industry. In the United States and a few other countries, natural gas is produced from shale and other types of sedimentary rock formations by forcing water, chemicals, and sand down a well under high pressure. This process is called hydraulic fracturing or fracking.

Fossil fuel companies are huge polluters
A report by The Guardian revealed that just 100 fossil fuel companies and their investors are responsible for 71% of global emissions since 1988. These companies have accelerated their extraction of coal, oil, and gas, even as the devastating environmental impact becomes increasingly clear. Despite commitments to reduce carbon emissions, such as the Paris Agreement, fossil fuel companies continue to invest heavily in coal, oil, and gas instead of renewable energy sources. For example, in 2019, BP spent millions on advertising its low-carbon energy initiatives, while over 96% of its annual expenditure remained focused on oil and gas.
The top 20 fossil fuel companies have contributed 480 billion tonnes of carbon dioxide equivalent since 1965, with 90% of their emissions attributed to the use of their products, such as petrol, jet fuel, and natural gas. Chevron, Exxon, BP, and Shell are among the top investor-owned corporations responsible for more than 10% of global carbon emissions. These companies risk wasting trillions of dollars by pursuing fossil fuel projects that may become worthless due to international action on climate change and the growing transition to renewable energy.
While some fossil fuel companies have begun investing in renewable energy projects, it is not happening at the scale or pace required to address the climate crisis. As Michael Mann, a leading climate scientist, stated, there is a "great moral failing" in allowing a small number of polluting interests to continue making record profits at the expense of a degraded planet. To combat climate change effectively, strong action is needed from policymakers, industries, and individuals alike.
