Climate Change: Fossil Fuels Extraction's Impact

Fossil fuels, including coal, oil, and natural gas, have been the dominant source of energy across the globe for over 150 years. The burning of fossil fuels releases greenhouse gases, such as carbon dioxide, into the Earth's atmosphere, contributing to climate change. This has led to various environmental issues, such as ocean acidification, extreme weather events, and sea level rise. The extraction and use of fossil fuels have had far-reaching impacts on the Earth's ecosystems and human health, with air and water pollution being significant concerns. While fossil fuels were essential during the Industrial Revolution and for industrialization, their negative consequences on health and the environment have sparked a transition towards low-carbon energy sources. As a result, the debate arises: what comes first, climate change or fossil fuel extraction?

Fossil fuels' impact on climate change

Fossil fuels, including coal, oil, and natural gas, have been the primary energy source for over 150 years, currently supplying about 80% of the world's energy. They are formed from the carbon-rich remains of plants and animals that lived and decomposed millions of years ago. When burned, fossil fuels release the stored carbon and other greenhouse gases into the Earth's atmosphere. This excess buildup of greenhouse gases, particularly carbon dioxide, is the leading cause of climate change.

The burning of fossil fuels has led to a dramatic increase in greenhouse gases, with fossil fuels accounting for over 75% of global greenhouse gas emissions and nearly 90% of carbon dioxide emissions. This has resulted in a thick blanket of gases in the Earth's atmosphere, trapping the sun's heat and causing global warming. The consequences of this are far-reaching, with the planet warming faster than ever before in recorded history. This has led to rising temperatures, altered weather patterns, and disrupted natural balances, posing risks to all life forms on Earth.

The impact of fossil fuels on climate change is evident in the following ways:

• Ocean Acidification: The ocean absorbs a significant portion of carbon dioxide emissions from fossil fuels, leading to a 30% increase in acidity over the last 150 years. This increased acidity makes it difficult for marine organisms to build shells and coral skeletons, threatening coral reefs, fishing, tourism, and the economy.
• Extreme Weather: Climate change, caused by burning fossil fuels, has led to more frequent and severe weather events, including wildfires, hurricanes, wind storms, flooding, and droughts. These events have resulted in significant economic costs, with the price of extreme weather in the US between 2016 and 2020 estimated at $606.9 billion.
• Sea Level Rise: The warming of the oceans and atmosphere due to climate change is causing the melting of glaciers and land-based ice sheets, resulting in global sea level rise. This has led to increased flooding, destructive storm surges, and saltwater intrusion, impacting the 40% of the US population living along the coasts.
• Air Pollution: Fossil fuels release hazardous air pollutants such as sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury. These pollutants contribute to acid rain, eutrophication, damage to crops and forests, and harm to wildlife and human health.
• Water Pollution: Oil spills and fracking fluids from fossil fuel extraction and transportation contaminate water sources, endangering both human and wildlife.
• Plastic Pollution: The vast majority of plastics are made from fossil fuels, and their production contributes to greenhouse gas emissions. Plastic waste pollutes the oceans, killing wildlife and contaminating the food chain.

The use of fossil fuels has significant climate, environmental, and health costs, known as externalities, which are not reflected in market prices. These externalities occur at every stage of the fossil fuel supply chain, from extraction and transportation to refining and burning. It is clear that the burning of fossil fuels has had a profound impact on climate change, and the continued use of these fuels will only worsen this crisis.

The transition away from fossil fuels

Policy Support and Regulatory Frameworks

Implementing policies that support the transition to renewable energy is crucial. This includes eliminating fossil fuel subsidies, which can generate significant taxpayer savings and encourage a shift to cleaner energy sources. Increasing the social cost of carbon (SCC) and implementing a federal clean electricity standard are also important steps. A carbon price, structured as a carbon tax, can also provide incentives to reduce emissions and create revenue streams for clean energy investments.

Investment in Renewable Energy Infrastructures

Transitioning to renewable energy requires significant investments in renewable energy infrastructures, such as wind, solar, and hydropower. These technologies are often cheaper than fossil fuels and can provide reliable and affordable energy. However, it is important to consider the challenges associated with renewable energy sources, such as the need for complementary storage technologies and the impact of mining for materials.

Energy Efficiency Measures

Improving energy efficiency is a crucial aspect of the transition. This includes improving the energy efficiency of buildings, vehicles, industrial processes, appliances, and equipment. This can reduce energy demand and cut emissions, while also providing economic benefits, such as job creation.

Technology Innovation and Research and Development (R&D)

Investing in technology innovation and research and development (R&D) is essential for improving renewable energy technologies and making them more accessible and efficient. This includes improving battery storage systems to increase energy system flexibility and accessibility.

Global Cooperation and Collective Action

Addressing climate change and transitioning to renewable energy requires global cooperation and collective action. It is important to consider the concerns and perspectives of countries in the Global South, who may have different priorities and development levels. Working together as equals is crucial to achieving a sustainable future for all.

Phasing Out Coal and Diversifying Economies

Phasing out coal and diversifying economies, especially those that are fossil fuel-rich, is a challenging but necessary part of the transition. Government-led initiatives and disclosure policies can help manage the impacts on affected communities and industries.

Addressing Environmental and Social Impacts

The transition to renewable energy should also address the environmental and social impacts of resource extraction, such as habitat destruction, increased pollutants and waste, reduced water quality, and negative health consequences. Sustainable practices that protect ecosystems and communities are essential.

Education and Community Engagement

Engaging with communities and ensuring their support for the transition is vital. Researchers and technology companies should adopt an interdisciplinary and community-engagement approach to ensure that communities understand and appreciate the efforts and technologies involved in the transition.

Fossil fuels' role in industrialisation

Fossil fuels, including coal

The environmental and health costs of fossil fuels

Fossil fuels, including coal, oil, and natural gas, have powered economies for over 150 years and currently supply about 80% of the world's energy. However, the use of fossil fuels comes at a significant cost to the environment and human health, known as externalities. These externalities occur at every stage of the fossil fuel supply chain, from extraction and transportation to refining and burning.

Environmental Costs

One of the most significant environmental impacts of fossil fuels is their contribution to climate change. When burned, fossil fuels emit greenhouse gases, such as carbon dioxide, which trap heat in the Earth's atmosphere. This leads to dramatic changes in the Earth's climate, including ocean acidification, extreme weather events, and sea-level rise. Ocean acidification, for example, makes it harder for marine organisms to build shells and coral skeletons, threatening coral reefs, fishing, tourism, and the economy.

Fossil fuels also cause air and water pollution, with hazardous pollutants such as sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury being released into the atmosphere. These pollutants can cause acid rain, eutrophication, damage to crops and forests, and harm to wildlife. Water pollution from oil spills and fracking fluids contaminate groundwater and drinking water sources, posing risks to both human and animal health.

Additionally, plastic pollution is another environmental consequence of fossil fuel use, with over 99% of plastics being made from fossil fuels. This contributes to wildlife death, food chain pollution, and the release of greenhouse gases during production.

Health Costs

The burning of fossil fuels has severe health impacts, with air pollution causing asthma, cancer, heart disease, and premature death. In the United States alone, 350,000 premature deaths in 2018 were attributed to fossil fuel-related pollution, with certain states, such as Pennsylvania, Ohio, and West Virginia, having higher rates. Globally, fossil fuel pollution is responsible for one in five deaths.

Communities of color and low-income communities are disproportionately affected by the health impacts of fossil fuels, with higher exposure to particulate matter pollution than the national average. Certain areas, such as "Cancer Alley" in Louisiana, have much higher cancer risks due to the proximity of chemical plants and oil refineries.

Policy Mechanisms

Recognizing the significant environmental and health costs of fossil fuels, several policy mechanisms have been proposed to reduce these externalities, including eliminating fossil fuel subsidies, increasing the social cost of carbon, implementing a federal clean electricity standard, and putting a price on carbon emissions. By addressing these externalities, society can move towards a more sustainable and equitable future, reducing the burden of environmental and health costs on vulnerable communities.

The extraction process of fossil fuels

The extraction of fossil fuels refers to the process of withdrawing fossil fuels from the environment for human use. The two main methods for removing fossil fuels from the ground are mining and drilling. Mining is used to extract solid fossil fuels, such as coal, by digging, scraping, or otherwise exposing buried resources. Drilling methods are used to extract liquid or gaseous fossil fuels, such as conventional oil and natural gas, which can be forced to flow to the surface.

In the case of coal mining, there are two primary techniques: surface mining and underground mining. Surface mining, which accounts for 62% of coal extraction, involves removing the top layers of soil and rock to access the coal. This method often employs highly invasive techniques, such as area strip mining and mountaintop removal, which can have devastating effects on local environments. Underground mining, on the other hand, creates tunnels in mountains to access coal reserves and accounts for 38% of coal extraction.

For liquid and gaseous fossil fuels, drilling methods are employed. This involves drilling vertical wells to access the resources. Initially, the pressure underground pushes the oil and gas to the surface. Once this pressure decreases, operators can inject gases or water to increase pressure and facilitate the rise of the resources. Pumps can also be installed to provide artificial lift for oil production. Additionally, operators may inject steam, gases, or chemicals to change the composition of the oil, making it easier to extract.

In recent years, the extraction of oil and gas has been revolutionized by the introduction of horizontal drilling and hydraulic fracturing (fracking). Horizontal drilling creates lateral wells for the oil and gas to flow through, while fracking involves pumping water, sand, and chemicals into the earth to fracture the shale rock, allowing the resources to flow into the wells and then to the surface. These techniques have made it profitable to extract oil and gas from almost impermeable shale rock formations deep underground.

The extraction of fossil fuels has had far-reaching impacts on the Earth's systems, including the destruction of habitats, increased pollution, reduced water quality, and the disruption of local communities. The burning of fossil fuels releases greenhouse gases, contributing to climate change and leading to extreme weather events, ocean acidification, and rising sea levels.
