Detailed explanation-1: -When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming.
Detailed explanation-2: -Researchers also estimate global economic losses from fossil fuel air pollution at $2.9 trillion each year, or approximately 3.3 percent of global GDP. In the United States alone, air pollution from burning fossil fuels is linked to an estimated 230, 000 deaths and $600 billion in economic losses annually.
Detailed explanation-3: -Fossil fuels – coal, oil and gas – are by far the largest contributor to global climate change, accounting for over 75 per cent of global greenhouse gas emissions and nearly 90 per cent of all carbon dioxide emissions. As greenhouse gas emissions blanket the Earth, they trap the sun’s heat.
Detailed explanation-4: -Human Activity Is the Cause of Increased Greenhouse Gas Concentrations. Over the last century, burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This increase happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.
Detailed explanation-5: -But burning them creates climate change and releases pollutants that lead to early death, heart attacks, respiratory disorders, stroke, asthma, and absenteeism at school and work. It has also been linked to autism spectrum disorder and Alzheimer’s disease.
