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. Already the average global temperature has increased by 1C.

Detailed explanation-2: -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.

Detailed explanation-3: -Some of these ways include: Releasing the greenhouse gases carbon dioxide (CO2) and nitrous oxide (N2O) into the atmosphere, which intensifies the greenhouse effect (the re-radiation of heat in the atmosphere), increasing the Earth’s average air temperatures.

Detailed explanation-4: -When fossil fuels are burned, they release nitrogen oxides into the atmosphere, which contribute to the formation of smog and acid rain. Major sources of nitrogen oxide emissions include: Cars and trucks. Coal-fired power plants.

Detailed explanation-5: -Since the Industrial Revolution, human activities have released large amounts of carbon dioxide and other greenhouse gases into the atmosphere, which has changed the earth’s climate. Natural processes, such as changes in the sun’s energy and volcanic eruptions, also affect the earth’s climate.
