Climate Change: Damaging Fossil Fuels And Our Future

The burning of fossil fuels is the primary cause of climate change, with fossil fuels accounting for over 75% of global greenhouse gas emissions and nearly 90% of all carbon dioxide emissions. When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. These gases trap heat in the Earth's atmosphere, causing global warming and climate change. The effects of burning fossil fuels are far-reaching, impacting both human and environmental health. Climate change, caused by the burning of fossil fuels, contributes to more frequent and severe extreme weather events, including wildfires, droughts, and flooding. These events have led to disasters costing billions of dollars and have had devastating impacts on ecosystems and communities. Additionally, the extraction and transportation of fossil fuels can result in irreversible spills, damaging nearby ecosystems and contaminating drinking water. With the understanding that humanity's use of fossil fuels is severely damaging our planet, there is an urgent need to phase out fossil fuels and transition to renewable energy sources.

Ocean acidification

When carbon dioxide dissolves into the ocean, it triggers a chemical reaction that increases its acidity over time. The carbon dioxide forms carbonic acid, which releases hydrogen and bicarbonate ions. The more hydrogen ions there are, the more acidic the water becomes. This process is called ocean acidification.

The effects of ocean acidification can ripple through the entire food chain, impacting both aquatic and terrestrial life, including humans. It also affects important sectors of the economy, such as fisheries and tourism, and food supply. For example, the U.S. shellfish industry is expected to lose more than $400 million annually by 2100 due to ocean acidification.

To tackle ocean acidification, the transition to clean energy sources and the reduction of carbon emissions are crucial. Additionally, protecting and enhancing carbon sinks, such as forests and wetlands, can help mitigate the impacts of carbon pollution on the oceans.

Extreme weather events

Fossil fuels are the dominant cause of global warming and climate change. The burning of fossil fuels releases large amounts of carbon dioxide, a greenhouse gas, into the atmosphere. Greenhouse gases trap heat in the atmosphere, causing global warming. The Intergovernmental Panel on Climate Change (IPCC) has found that emissions from fossil fuels are the primary cause of global warming. In 2019, fossil fuels accounted for 74% of U.S. greenhouse gas emissions.

Rising global temperatures caused by the burning of fossil fuels have increased the likelihood and intensity of extreme weather events. Climate change, driven by the burning of fossil fuels, is contributing to more frequent and severe extreme weather events, including wildfires, hurricanes, wind storms, flooding, and droughts. These extreme weather events have led to disasters costing billions of dollars and causing widespread damage and disruption.

Wildfires:

Wildfires have become more frequent and intense due to rising temperatures and drier conditions caused by climate change. Wildfires burn longer and wider, destroying vast areas of land and causing hazardous air pollution that can spread beyond the affected region. In 2023, smoke from nearly 900 wildfires in Canada triggered air quality alerts affecting 70 million people in the eastern United States. California, Oregon, Washington, and Colorado have experienced explosive fires, forcing evacuations and causing loss of life, property, and businesses.

Hurricanes:

Hurricanes draw their energy from warm ocean water, and as global temperatures rise, hurricanes are becoming more powerful and intense. In September 2024, Hurricane Helene caused historic flooding in the Southeast United States, resulting in fatalities and power outages. Warmer ocean waters also fuel the formation of intense hurricanes earlier in the season, such as Hurricane Beryl, the earliest Category 5 hurricane on record.

Flooding:

Climate change has led to an increase in the frequency and severity of flooding events. Rising global temperatures cause glaciers and land-based ice sheets to melt, resulting in global sea level rise. Sea levels have risen by about 9 inches since the late 1800s, leading to more frequent and destructive flooding events, storm surges, and saltwater intrusion. Coastal communities are particularly vulnerable to the impacts of sea-level rise, and defending them is expected to incur significant costs.

Droughts:

Droughts have become more severe and long-lasting due to climate change. Higher temperatures cause moisture to evaporate from water bodies and soil, leading to drier conditions. The American West is currently experiencing a mega-drought that ranks among the worst in the past 1,200 years.

Heatwaves:

As global temperatures rise, heatwaves become more frequent and intense. Heatwaves pose health risks, particularly to vulnerable populations, and strain energy systems as demand for air conditioning increases. Extreme heat can also contribute to wildfires and impact various sectors, including agriculture and energy production.

Winter Storms:

Climate change may contribute to more extreme winter weather. As the atmosphere warms, it traps water vapor, leading to heavier snowfall when temperatures drop. Additionally, the warming of the Arctic may be weakening the jet stream and disrupting the polar vortex, resulting in icy winters and freezing conditions.

The impacts of extreme weather events are far-reaching and devastating, affecting communities, economies, and the environment. It is crucial to address the root cause of these events by reducing the use of fossil fuels and transitioning to renewable and clean energy sources.

Sea level rise

Sea levels have risen about 9 inches since the late 1800s, causing more frequent flooding, destructive storm surges, and saltwater intrusion. This is due to a combination of the oceans expanding as they warm, and melting glaciers and ice sheets adding more water to the oceans.

The burning of fossil fuels is the primary cause of rising sea levels. When fossil fuels are burned, they release carbon dioxide and other greenhouse gases into the atmosphere, warming the Earth and the oceans. Research published in Nature Climate Change found that the burning of fossil fuels is responsible for the majority of sea-level rise since the late 20th century.

The impact of rising sea levels is already being felt in coastal areas. Cities like Norfolk, Virginia, and Venice are experiencing many more high-tide floods, which damage roads, sewer systems, and other infrastructure. Sea-level rise is also making hurricanes and other storms more damaging and deadly. The high winds from hurricanes push a wall of water, known as a "storm surge", toward the shore. Sea-level rise gives those waves a head start, propelling them further inland.

Scientists warn that if fossil fuel emissions continue unchecked, the Antarctic Ice Sheet would melt entirely, causing sea levels to rise by 164 feet (50 meters) or more. This would result in major coastal cities, such as New York, Tokyo, and Shanghai, being swallowed by the ocean. Even if greenhouse gas emissions are significantly cut, we can still expect one to two feet of additional sea-level rise by the end of the century due to past emissions.

The impacts of rising sea levels are expected to displace tens to hundreds of millions of people, as more than 10% of the world's population lives in coastal areas that are less than ten meters (about 33 feet) above sea level. In addition, rising sea levels threaten to flood large areas of farmland and make freshwater sources too salty to drink.

Air pollution

Fossil fuels are a major contributor to air pollution, which has devastating effects on both the environment and human health. When fossil fuels are burned, they release harmful pollutants into the atmosphere, including sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury. These pollutants have far-reaching impacts on the planet and human health.

One of the most significant ways in which fossil fuels contribute to air pollution is by emitting greenhouse gases, primarily carbon dioxide, which trap heat in the Earth's atmosphere and lead to global warming. This, in turn, causes climate change, resulting in rising sea levels, extreme weather events, biodiversity loss, and species extinction. According to the Intergovernmental Panel on Climate Change (IPCC), emissions from fossil fuels are the dominant cause of global warming. In 2018, 89% of global CO2 emissions came from fossil fuels and industry.

The burning of fossil fuels also releases hazardous air pollutants that have severe health impacts. Fine particulate matter, or PM 2.5, from burning fossil fuels has been linked to various health problems, including cardiovascular disease, cancer, tissue damage, asthma, and other respiratory ailments. Exposure to air pollution from fossil fuels has been found to disproportionately affect vulnerable groups, such as children, the elderly, low-income communities, and people of color. In 2018, more than 8 million people died from fossil fuel pollution worldwide, making it responsible for about one in five deaths globally.

In addition to the health impacts on humans, air pollution from fossil fuels also causes environmental damage. It leads to acid rain, which contaminates freshwater sources and harms aquatic ecosystems by reducing oxygen levels and causing harmful algal blooms. It also damages crops and forests and harms wildlife. The release of nitrogen oxides from burning fossil fuels contributes to the formation of smog and acid rain, further degrading air quality and affecting the environment.

The effects of air pollution from fossil fuels are widespread and severe, underscoring the urgent need to transition to cleaner and more sustainable energy sources. By reducing our reliance on fossil fuels and adopting renewable and efficient energy alternatives, we can mitigate the harmful impacts of air pollution on both human health and the environment.
