Answers. Best Answer: Summarised very briefly: Fossil fuels are the largest anthropogenic (human-induced) cause of greenhouse gas emissions. When fossil fuels (oil/coal) are burnt they produce carbon dioxide.Carbon dioxide absorbs the sun's energy and re-emits it as heat energy (infra-red).Power plants and motor vehicles are the largest contributors of human-induced carbon dioxide emissions.he greenhouse effect has to do with the amount of cloud (water vapor) cover. Clouds tend to insulate the ground, holding in the temperature at night and keeping the ground from excepting some of the radiation during the day. RichardH Â· 4 years ago.
