Detailed explanation-1: -Coal produces more CO2 per unit of energy than natural gas does when burned. Coal consumption for electricity generation produces 209 pounds of CO2 per million British thermal units (MMBtu), compared with 117 pounds of CO2/MMBtu for natural gas.
Detailed explanation-2: -As greenhouse gas emissions blanket the Earth, they trap the sun’s heat. This leads to global warming and climate change.
Detailed explanation-3: -Coal is a fossil fuel, and is the dirtiest of them all, responsible for over 0.3C of the 1C increase in global average temperatures. This makes it the single largest source of global temperature rise. Oil releases a huge amount of carbon when burned-approximately a third of the world’s total carbon emissions.
Detailed explanation-4: -Greenhouse gases trap sun’s heat energy. Prevents drastic fall of temperature at night. Refracts the sun’s heat energy back into space.
