Detailed explanation-1: -CO2 from fossil fuels as when the amount of carbon dioxide increases in atmosphere it increases the temperature.
Detailed explanation-2: -Greenhouse Gases Carbon dioxide, methane, and nitrous oxide concentrations are now more abundant in the earth’s atmosphere than any time in the last 800, 000 years. These greenhouse gas emissions have increased the greenhouse effect and caused the earth’s surface temperature to rise.
Detailed explanation-3: -Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy. Fossil fuels like coal and oil contain carbon that plants pulled out of the atmosphere through photosynthesis over many millions of years; we are returning that carbon to the atmosphere in just a few hundred.
