Burning Fossil Fuels: Can We Stop Climate Change?

Burning fossil fuels has had a devastating impact on the planet, and it is clear that humanity must wean itself off this cheap and abundant source of energy. Fossil fuels are the dominant cause of global warming, and the large-scale use of them tops the list of factors contributing to climate change. The burning of fossil fuels releases carbon dioxide, a greenhouse gas that traps heat in the atmosphere, causing global warming. Other harmful pollutants are also released, including sulfur dioxide, ozone, nitrogen oxides, and soot, which have detrimental effects on human health and the environment.

However, despite the urgent need to address climate change, simply burning less fossil fuel may not be enough to stop it.

Fossil fuels are a cheap and abundant energy source

There are three types of fossil fuels: coal, oil, and natural gas. They are formed from the decomposition of carbon-based organisms that died and were buried millions of years ago. Over time, the remains of these organisms were compressed and heated, forming carbon-rich deposits of coal, oil, or natural gas.

Fossil fuels are abundant because they were formed over millions of years, essentially storing the sun's energy over time. They are cheap because they are widely distributed and easy to extract, transport, and use. Oil, for example, is a liquid, which means it can be pumped and transported easily. It is also energy-dense, which means a small amount of oil contains a lot of energy. These qualities make oil ideal for transportation.

Fossil fuels have allowed humanity to move away from relying solely on current solar flows (i.e., real-time solar energy). Before the widespread use of fossil fuels, solar energy met all of humanity's energy needs. People burned biomass (plants) for heat and light and used horses for transportation. As the human population grew and became more urban, this bio-based energy system became problematic. In England, for example, wood became scarce and expensive in the 1500s and 1600s as the growing population used it for fuel and building material.

The discovery and utilization of fossil fuels opened new doors for humanity. They allowed us to use more energy than today's photosynthesis could provide and freed us from our reliance on current solar flows. Fossil fuels powered the industrial revolution, pulled millions of people out of poverty, and shaped the modern world.

Burning fossil fuels releases carbon dioxide, a greenhouse gas

Carbon dioxide is a greenhouse gas, meaning it traps heat in the Earth's atmosphere. This process, known as the greenhouse effect, is essential for making the Earth warm enough to support life. However, excessive greenhouse gas emissions have led to global warming and climate change. The burning of fossil fuels is the primary cause of current climate change, as it releases large amounts of carbon dioxide, a major driver of global warming.

The effects of burning fossil fuels are far-reaching and impact both human and environmental health. The release of carbon dioxide and other greenhouse gases, such as nitrous oxide, intensifies the greenhouse effect, leading to an increase in the Earth's average air temperatures. These greenhouse gases can remain in the atmosphere for decades to centuries, continuing to trap heat and contribute to climate change.

In addition to carbon dioxide, burning fossil fuels also emits other pollutants, including sulfur dioxide, nitrogen oxides, and soot. These pollutants contribute to air quality issues, such as smog, and have detrimental effects on human health. Respiratory diseases, asthma, bronchitis, and lung cancer have all been linked to the inhalation of these pollutants.

The large-scale use of fossil fuels has severe consequences for the planet and humanity. To mitigate climate change, it is crucial to reduce greenhouse gas emissions and transition to cleaner, renewable energy sources. While this transition may be challenging, it is necessary to protect the environment and ensure a sustainable future for generations to come.

Fossil fuels are the dominant cause of global warming

The Intergovernmental Panel on Climate Change (IPCC) has confirmed that emissions from fossil fuels are the dominant cause of global warming. In 2018, 89% of global CO2 emissions originated from fossil fuels and industry. Fossil fuels, including coal, oil, and natural gas, are formed from the decomposition of carbon-based organisms that died millions of years ago. These fossil fuels are extracted and burned to generate energy, produce plastic, steel, and various other products.

Coal is the most polluting fossil fuel and is responsible for over 0.3 degrees Celsius of the 1-degree increase in global average temperatures. Oil, on the other hand, releases a significant amount of carbon when burned, contributing approximately a third of the world's total carbon emissions. Natural gas, often touted as a cleaner alternative, is still a fossil fuel that accounts for a fifth of global carbon emissions.

The impact of fossil fuels on climate change is evident. The average global temperature has already increased by 1 degree Celsius, and warming above 1.5 degrees Celsius will lead to dire consequences, including sea-level rise, extreme weather events, biodiversity loss, species extinction, food scarcity, and worsening health and poverty for millions worldwide.

To limit global warming to 1.5 degrees Celsius above pre-industrial levels, the IPCC warns that fossil fuel emissions must be halved within 11 years. This will require a significant reduction in the use of fossil fuels and a transition to renewable and low-carbon energy sources. While burning less fossil fuel is a crucial step in mitigating climate change, it must be accompanied by broader systemic changes to effectively address this global challenge.

Fossil fuel companies are aware of the climate crisis

In 2024, leaked documents revealed that major fossil fuel companies, including Exxon, Shell, BP, and Chevron, had privately acknowledged the dangers of burning fossil fuels. These companies had also lobbied against climate laws and regulations that they publicly claimed to support. In some cases, they even went as far as to spread disinformation and fund ongoing efforts to delay action on the climate crisis.

This is not a new development. As early as 1954, the fossil fuel industry funded some of the world's most foundational climate science, including the early research of Charles Keeling, which tracked the steady increase of atmospheric carbon that drives the climate crisis. Despite this knowledge, the industry publicly denied the science for decades and continued to produce and promote the use of fossil fuels.

The large-scale use of fossil fuels is the top contributor to climate change. Fossil fuels, when burned, release carbon dioxide (CO2), a greenhouse gas that traps heat in the Earth's atmosphere, causing global warming. CO2 emissions from fossil fuels are the dominant cause of global warming, with the Intergovernmental Panel on Climate Change (IPCC) finding that 89% of global CO2 emissions in 2018 came from fossil fuels and industry.

Fossil fuel companies have not only been aware of the climate crisis but have also actively worked to prevent or delay climate action. They have engaged in campaigns of deception and disinformation, with internal documents revealing their efforts to confuse and mislead the public. They have also influenced politicians and regulators through lobbying and funding.

The role of fossil fuel companies in the climate crisis is clear, and they must be held accountable for their actions.

Fossil fuels also produce other harmful pollutants

Fossil fuels produce a range of harmful pollutants, which have significant impacts on both human health and the environment. These pollutants are released at every stage of the fossil fuel supply chain, from extraction to combustion.

Air Pollution

The burning of fossil fuels releases a variety of harmful substances into the atmosphere, including sulfur dioxide, ozone, nitrogen oxides, and soot. These pollutants contribute to air pollution, which has been linked to a range of respiratory and cardiovascular issues, including asthma, bronchitis, and lung cancer. According to the World Health Organization, air pollution from fossil fuels leads to around 7 million deaths worldwide each year.

Water Pollution

Fossil fuels are also a major contributor to water pollution. Oil spills, for example, can have devastating effects on aquatic ecosystems, killing wildlife and damaging habitats. Additionally, the extraction and transportation of fossil fuels can lead to water pollution, as fuels like oil are often transported over long distances, increasing the risk of accidents and spills.

Plastic Pollution

Plastics, which are predominantly made from fossil fuels, also contribute to environmental pollution. Around 300 million tons of plastic waste is produced globally each year, with a significant amount ending up in the ocean. This plastic pollution harms marine life and pollutes the food chain.

Climate Change

In addition to these direct health and environmental impacts, fossil fuels are a major driver of climate change. When burned, fossil fuels release large amounts of carbon dioxide, a greenhouse gas that traps heat in the Earth's atmosphere, leading to global warming. This, in turn, contributes to rising sea levels, extreme weather events, biodiversity loss, and species extinction.

Social and Economic Impacts

The impacts of fossil fuel pollution disproportionately affect vulnerable communities, including communities of color and low-income communities. These communities often bear the brunt of the health and environmental consequences, such as increased rates of respiratory illnesses and exposure to toxic pollutants. Additionally, the economic costs of fossil fuel pollution are significant, with the health impacts of fossil fuel-generated electricity in the United States estimated to cost up to $886.5 billion annually.
