Fossil fuels emit harmful air pollutants, causing asthma, cancer, heart disease and premature death
Burning fossil fuels emits harmful air pollutants, which have severe impacts on human health, causing and exacerbating asthma, increasing the risk of several types of cancer, contributing to cardiovascular issues, and leading to premature death.
Air pollution from fossil fuels includes the release of nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), and methane (CH4). Breathing in NO2 can cause asthma and worsen existing lung conditions. SO2 is also harmful to the lungs and plants. CO is dangerous when it builds up in enclosed spaces, and CH4 contributes to air pollution. Ozone, an irritating pollutant for the lungs and airways, is another trigger for asthma. Research has shown that air pollution can cause asthma and worsen symptoms, leading to increased hospital visits and, in some cases, premature death. In the United States alone, there are approximately 28 million people with asthma.
The processing and consumption of fossil fuels are associated with an increased risk of several types of cancer. For example, exposure to benzene, a substance used in fracking wells and oil refineries, has been linked to various blood cancers, liver cancer, and bladder cancer. The transportation of fossil fuels can also increase communities' exposure to carcinogens, as seen in the Ohio train derailment incident.
Particulate air pollution from fossil fuel combustion has been linked to cardiovascular issues, including ischemic heart disease events and increased cardiovascular hospitalizations. Climate change, fueled by greenhouse gas emissions from fossil fuels, contributes to cardiovascular risk through increased wildfires.
The burning of fossil fuels releases carbon dioxide (CO2) and nitrous oxide (N2O), greenhouse gases that accumulate in the atmosphere and contribute to global warming and climate change. The net effect of burning fossil fuels is warming due to the long-term presence of these greenhouse gases in the atmosphere. The health impact of burning fossil fuels is significant, with research attributing approximately 8 million premature deaths globally in 2018 to fossil fuel pollution. This accounts for about 1 in 5 deaths worldwide, with even higher proportions in certain states and countries.

Burning fossil fuels releases carbon dioxide, causing climate change and global warming
The burning of fossil fuels has been a primary source of energy for over a century, powering our cars, businesses, and homes. Fossil fuels refer to oil, natural gas, and coal. However, burning these fuels releases carbon dioxide and other greenhouse gases, which have far-reaching effects on our climate and ecosystems.
Carbon dioxide (CO2) emissions from burning fossil fuels trap heat in the Earth's atmosphere, leading to the greenhouse effect and causing global warming and climate change. The net effect of burning fossil fuels is warming, despite the slight cooling effect of airborne particles like soot and sulfate aerosols, which reflect sunlight back into space. The heating caused by the greenhouse effect is more significant as the gases remain in the atmosphere for decades to centuries.
The release of carbon dioxide and other greenhouse gases from burning fossil fuels has severe consequences for the environment and human health. The Earth's ecosystems are being altered, with glaciers and land-based ice sheets melting, resulting in global sea-level rise, more frequent flooding, and destructive storm surges. Climate change also contributes to more frequent and severe extreme weather events, including wildfires, hurricanes, wind storms, droughts, and flooding.
Burning fossil fuels also emits harmful air pollutants, including nitrogen oxides, which contribute to smog and acid rain. Oil spills during the extraction, transportation, and refining of fossil fuels can have devastating impacts on communities, wildlife, and habitats. Additionally, air pollution from burning fossil fuels is linked to respiratory illnesses, asthma, heart disease, and premature deaths.
The combustion of fossil fuels has significant climate, environmental, and health costs, and it is essential to transition to cleaner energy sources to mitigate these impacts and reduce global warming and climate change.

Oil spills from extraction, transportation and refining harm wildlife, destroy habitats and erode shorelines
Oil spills are a significant consequence of the extraction, transportation, and refining of fossil fuels, and they have devastating impacts on the environment and wildlife. Oil spills harm wildlife, destroy habitats, and erode shorelines, leaving long-lasting ecological damage in their wake.
Oil spills can have immediate and lethal effects on marine and coastal wildlife, including seabirds, marine mammals, and sea turtles. Seabirds are particularly vulnerable, as their feathers can become coated in oil, reducing their ability to maintain body temperature and causing them to succumb to hypothermia. Oil can also cause skin and eye irritation, alter immune systems, and lead to reproductive and developmental issues. In some cases, oil spills can directly result in the mortality of wildlife, as seen in the 2010 BP Deepwater Horizon spill, where countless birds, turtles, fish, marine mammals, and plants perished.
The magnitude of harm caused by oil spills to wildlife depends on factors such as the duration of exposure, the amount of oil ingested or inhaled, and the life stage of the affected organisms. Eggs, larvae, and juveniles are often more susceptible to the toxic effects of oil, and disruptions to their life cycles can have ripple effects throughout the food chain. Additionally, carnivorous wildlife that feed on prey exposed to oil sediments along shorelines can suffer indirect health complications.
Oil spills also have long-term ecological consequences, eroding shorelines and destroying habitats. They can smother small fish and invertebrates, and when oil washes ashore, it can harm terrestrial creatures such as snails, clams, and other animals. The use of dispersants to break down oil can further impact shoreline habitats and harm benthic animals in deeper waters.
The response to oil spills, including cleanup operations, can also have unintended consequences. While dispersants can reduce the toxic effects of oil on wildlife, they may also increase the harmful impact on bird feathers, making it more difficult for birds to regulate their body temperature.
Overall, oil spills from the extraction, transportation, and refining of fossil fuels have far-reaching and detrimental effects on wildlife, habitats, and shorelines. These impacts underscore the urgency of transitioning to cleaner energy sources and mitigating the environmental and ecological costs of fossil fuel use.

The burning of fossil fuels is causing sea levels to rise, leading to flooding and destructive storm surges
The burning of fossil fuels is a major contributor to climate change, and one of its most significant impacts is the resulting rise in sea levels. Fossil fuels, formed from the remains of ancient plants and organisms, have been a primary energy source since the 1700s. However, the combustion of these fuels releases vast amounts of carbon dioxide (CO2) and nitrous oxide (N2O) into the atmosphere, leading to the greenhouse effect and global warming. This warming causes glaciers and ice sheets to melt, adding water to the oceans and leading to a rise in sea levels.
The consequences of rising sea levels are far-reaching and devastating. One of the most immediate impacts is an increased frequency of flooding. High-tide or "nuisance" flooding, while not generally deadly, has become 300-900% more frequent in the last 50 years. This type of flooding can be highly disruptive and costly. As sea levels continue to rise, more severe and deadly flooding events will become more common.
Additionally, rising sea levels exacerbate the impact of storms and hurricanes. Higher background water levels mean that storm surges, such as those associated with Hurricane Katrina and "Superstorm" Sandy, push farther inland, leading to destructive consequences. The combination of rising seas and more intense storms poses a significant threat to coastal communities and infrastructure. Roads, bridges, subways, water supplies, power plants, and other vital systems are all at risk of damage or destruction.
The burning of fossil fuels is driving a positive feedback loop that intensifies the impacts of climate change. As sea levels rise due to melting ice, more liquid water is transferred from land to the ocean, further contributing to sea level rise. This process threatens to reshape the Antarctic ice sheets irreparably, leading to a potential 50- to 60-meter (160- to 200-foot) rise in sea levels if all remaining fossil fuel resources are burned. Such a rise would submerge many highly populated areas, including major cities like New York and Washington, DC, affecting over a billion people.

Fossil fuel combustion is the leading environmental threat to global paediatric health and equity
Fossil fuel combustion releases large amounts of carbon dioxide (CO2) and other greenhouse gases, such as nitrous oxide (N2O) and methane. These gases trap heat in the Earth's atmosphere, contributing to global warming and climate change. The warming effect of greenhouse gases far outweighs the cooling impact of airborne particles like soot and sulfate aerosols, which only remain in the atmosphere for a short period. The carbon dioxide released from fossil fuel combustion also leads to ocean acidification, as the oceans absorb a significant portion of this CO2, altering their chemistry.
The emissions from burning fossil fuels include a range of toxic air pollutants, such as nitrogen oxides, which contribute to the formation of smog and acid rain. These pollutants have severe health consequences, including respiratory illnesses, asthma, heart disease, and an increased risk of cancer. Globally, fossil fuel pollution is linked to one in five deaths, with 350,000 premature deaths attributed to fossil fuel-related pollution in the United States alone in 2018.
The impact of fossil fuel combustion on paediatric health is profound. Air pollution from fossil fuels can impair cognitive and behavioural development, with potential neurodevelopmental effects. Studies have found links between maternal exposure to particulate matter (PM2.5) during pregnancy and an increased risk of preterm birth and low birth weight, which are themselves risk factors for various neurodevelopmental disorders. Additionally, children born prematurely or with low birth weight are more susceptible to malnutrition and infectious diseases, further exacerbating the health risks associated with air pollution.
The effects of fossil fuel combustion contribute to global inequality and environmental injustice, disproportionately impacting the young, the poor, and minorities, particularly in developing countries. The socioeconomic burden of air pollution and climate change falls heavily on vulnerable communities, and the lack of comprehensive policies to protect these groups exacerbates the problem.
Addressing the threats posed by fossil fuel combustion requires a holistic approach, including the development and implementation of global mitigation strategies and policies to reduce disparities and protect the health and future of children worldwide.

Frequently asked questions
Burning fossil fuels releases greenhouse gases, such as carbon dioxide, into the atmosphere, contributing to climate change and global warming. It also emits harmful air pollutants, which can cause respiratory illnesses and other chronic diseases, including asthma, cancer, and heart disease.
Fossil fuels are formed from the burial of photosynthetic organisms, which, during their growth, removed carbon dioxide from the atmosphere and the ocean. Burning these fossil fuels returns this carbon to the atmosphere as carbon dioxide, at a rate much faster than it was removed and faster than the carbon cycle can remove it. This carbon dioxide accumulates in the atmosphere, intensifying the greenhouse effect and causing global warming.
The combustion of fossil fuels releases toxic air pollutants, including nitrogen oxides, which contribute to the formation of smog and acid rain. These pollutants have been linked to a range of health issues, including respiratory illnesses, asthma, cancer, and heart disease. Globally, fossil fuel pollution is responsible for one in five deaths, with 350,000 premature deaths in the United States in 2018 attributed to fossil fuel-related pollution.
