Fossil fuels cause climate change, leading to extreme weather events
Fossil fuels, including 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 greenhouse gases, such as carbon dioxide, which trap heat in the Earth's atmosphere, leading to climate change and global warming. This, in turn, has severe consequences, including extreme weather events.
Climate change, driven by the burning of fossil fuels, is causing more frequent and intense extreme weather events worldwide. These events include wildfires, hurricanes, wind storms, flooding, and droughts, resulting in costly disasters. From 2016 to 2020, the United States incurred estimated costs of $606.9 billion due to these extreme weather events. As global temperatures continue to rise, the frequency and intensity of these events are expected to increase further.
The Intergovernmental Panel on Climate Change (IPCC) has warned that urgent action is needed to halve fossil fuel emissions within a decade to limit global warming to 1.5°C above pre-industrial levels. Despite the Paris Agreement's commitment to reduce carbon emissions, global fossil fuel production is projected to exceed the limits required to meet this target. This inaction will likely result in severe consequences, as outlined by the United Nations Environment Programme's (UNEP) 2023 report, which predicts that more than double the amount of fossil fuel production planned for 2030 will be inconsistent with the goal of limiting warming to 1.5°C.
The impacts of extreme weather events disproportionately affect low-income countries and communities of color, exacerbating existing inequalities. Additionally, rising temperatures and climate change have led to increased sea levels, causing more frequent flooding, destructive storm surges, and saltwater intrusion. With a significant portion of the global population living along coasts, the costs of defending coastal communities from sea-level rise will be substantial.
It is evident that the continued reliance on fossil fuels is driving climate change and leading to increasingly severe and frequent extreme weather events. To mitigate these impacts, a transition to renewable energy sources and improved energy efficiency is imperative. Reducing the supply and demand for fossil fuels is crucial to limiting global temperature rise and its consequent effects on extreme weather events.

They are the dominant cause of global warming
The combustion of fossil fuels releases carbon dioxide (CO2), a greenhouse gas that is the most significant human-induced contributor to climate change. In 2019, fossil fuels accounted for 74% of US greenhouse gas emissions, with nearly 25% of emissions originating from fossil fuels extracted from public lands. 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 were attributed to fossil fuels and industry.
Coal, the dirtiest fossil fuel, has contributed over 0.3°C to the 1°C increase in global average temperatures, making it the single largest source of global temperature rise. Oil, another fossil fuel, releases approximately one-third of the world's total carbon emissions when burned. Natural gas, often promoted as a cleaner alternative to coal and oil, is still a fossil fuel that accounts for one-fifth of the world's carbon emissions.
The combustion of fossil fuels has severe health consequences, particularly for children and vulnerable communities. Fossil fuel emissions contain toxic air pollutants that contribute to global warming and have detrimental effects on human health. These pollutants include benzene, linked to childhood leukaemia and blood disorders, and formaldehyde, a known carcinogen. The health impacts of fossil fuel emissions are widespread, with one in five deaths globally attributed to fossil fuel pollution. In the United States alone, 350,000 premature deaths in 2018 were associated with fossil fuel-related pollution, disproportionately affecting communities of colour and low-income communities.
The extraction and processing of fossil fuels also have significant environmental impacts. Strip mining, for example, can destroy vast areas of terrain, including forests and mountaintops, to access underground coal or oil reserves. The unearthing, processing, and transportation of fossil fuels disrupt landscapes and ecosystems, requiring extensive infrastructure and generating toxic waste that can contaminate groundwater and drinking water sources.
To address the issue of global warming caused by fossil fuels, urgent action is needed to transition to renewable energy sources and reduce fossil fuel emissions. The 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. While governments have committed to reducing carbon emissions through agreements like the Paris Agreement, more decisive action is required to align with these targets.

Fossil fuel extraction damages precious land and people's livelihoods
Fossil fuel extraction has a profoundly negative impact on the environment and the people who depend on the land for their livelihoods. The process of extracting fossil fuels, such as drilling and mining, can cause irreversible damage to ecosystems and natural habitats. For example, strip mining involves scraping and blasting entire swaths of terrain, including forests and mountaintops, to access coal or oil. This destruction of land not only harms wildlife and biodiversity but also disrupts the livelihoods of people who rely on these ecosystems for food, income, and cultural identity.
Indigenous peoples are disproportionately affected by fossil fuel extraction due to land grabs, as most remaining fossil fuel deposits are situated on their ancestral lands. In many cases, they are forcibly evicted from their homes to make way for extraction projects. Their cultural connections to the land and natural environment are threatened, and they face attacks, arrests, and even death when they peacefully protest to protect their land. For instance, members of the Amazonian Women collective in Ecuador received death threats and were forced to leave their homes due to their opposition to fossil fuel extraction.
The infrastructure built for fossil fuel extraction, such as roads, facilities, pipelines, and drilling sites, can also fragment habitats and destroy large areas of wilderness. The construction process requires heavy equipment and can leave behind permanent scars on the land. Even after fossil fuel companies abandon these sites, the land may take centuries to recover, if it ever fully does. The noise, human activity, and vehicle traffic associated with extraction operations can disrupt wildlife communication, breeding, and nesting patterns, further endangering already vulnerable species.
Additionally, fossil fuel extraction poses risks of toxic spills and water contamination. Oil spills during extraction, transportation, and refining can devastate nearby ecosystems, destroy biodiversity, and contaminate drinking water sources. Coal mining and fracking generate toxic waste that can pollute water bodies, and fracking uses enormous amounts of water, producing wastewater that often contains harmful substances like arsenic, lead, and mercury. These spills and contamination incidents have severe consequences for both the environment and the people who depend on these natural resources for their survival.
Fossil fuel development can also have direct health impacts on nearby communities. Toxic substances can leak into the soil and drinking water, leading to various health issues, including cancer, birth defects, and liver damage. Air pollution from extraction operations, such as drilling and processing facilities, exposes people to harmful pollutants, causing respiratory problems and contributing to premature deaths. Vulnerable communities, including Black, Brown, Indigenous, and low-income groups, bear the brunt of these health risks as they are more likely to live in areas with higher pollution levels.

Burning fossil fuels releases harmful air pollutants, causing health issues
The burning of fossil fuels releases harmful air pollutants, causing a range of health issues. Fossil fuels, including coal, oil, and natural gas, have a high carbon content. When burned, they emit greenhouse gases, such as carbon dioxide (CO2) and nitrous oxide (N2O), which contribute to global warming and climate change. These gases can remain in the atmosphere for extended periods, intensifying the greenhouse effect and increasing the Earth's average air temperatures.
The combustion of fossil fuels also releases toxic air pollutants, including benzene, formaldehyde, sulfur dioxide, nitrogen oxides, and particulate matter. These pollutants have been linked to various health problems, including respiratory diseases, asthma, cancer, and heart disease. Globally, fossil fuel pollution is responsible for a significant number of premature deaths, with vulnerable communities, such as low-income areas and communities of color, disproportionately affected.
In addition to the direct health impacts, the burning of fossil fuels also contributes to climate change, which further exacerbates health issues. For example, climate change leads to more frequent and severe extreme weather events, such as wildfires, hurricanes, and droughts, which can have detrimental effects on human health and well-being. The combustion of fossil fuels also contributes to ocean acidification, which disrupts marine ecosystems and has indirect health consequences.
The release of toxic air pollutants from burning fossil fuels can have transgenerational impacts, potentially affecting newborns and future generations. Exposure to these pollutants during early life stages can impair cognitive and behavioral development and increase the risk of respiratory illnesses and other chronic diseases. The health impacts of fossil fuel combustion disproportionately affect children, especially those from underprivileged backgrounds, highlighting the environmental injustice associated with fossil fuel usage.
Furthermore, the combustion of fossil fuels has been linked to global pediatric health threats, particularly among the poor and certain minorities. The combination of air pollution and climate change resulting from fossil fuel combustion synergistically magnifies the harm to children's health and development. This includes impairments in cognitive and behavioral development, respiratory illnesses, and other chronic conditions, underscoring the urgency to address the unsustainable practices associated with fossil fuel usage.

They are a leading cause of environmental injustice, impacting vulnerable communities
The use of fossil fuels has significant climate, environmental, and health costs. These costs disproportionately affect vulnerable communities, making fossil fuels a leading cause of environmental injustice.
Fossil fuel emissions are the dominant cause of global warming and climate change. In 2018, 89% of global CO2 emissions came from fossil fuels and industry. Climate change disproportionately affects people who already face discrimination and marginalization. People in countries that have contributed the least to climate change suffer the worst of its impacts. For example, the health impacts of extremely high temperatures disproportionately affect Black and Hispanic Americans, who are exposed to 56% and 63% more particulate matter pollution, respectively, than they produce.
Fossil fuel pollution is a leading environmental threat to global pediatric health and equity. The combustion of fossil fuels releases toxic air pollutants that harm the health of workers and neighbouring communities. These pollutants can cause neurodevelopmental impacts, respiratory illness, and other chronic diseases, with children being more vulnerable to these adverse effects than adults. Fossil fuel pollution also contributes to global inequality and environmental injustice, as the young, the poor, and certain minorities, especially in developing countries, are most vulnerable to the impacts of toxic air pollutants and CO2-driven climate change.
The extraction of fossil fuels also damages precious land and the livelihoods of people who live on that land. For example, strip mining can release giant carbon stores held naturally in forests and scrape away entire swaths of terrain, including forests and whole mountaintops. This can lead to the displacement of communities and the loss of their ancestral land. In Ecuador, members of the Amazonian Women collective received death threats, were attacked, had to leave their homes, and were arrested due to their work to protect their ancestral land from the damages of fossil fuel extraction.
The combustion of fossil fuels also contributes to water pollution. Oil spills and fracking fluids can contaminate groundwater and drinking water with substances like arsenic, lead, chlorine, and mercury. This can have disastrous impacts on the health of people who rely on these water sources.
