49+ Natural Sources Of Greenhouse Gases UK. A greenhouse gas (sometimes abbreviated ghg) is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect. Carbon dioxide, methane share of global ghg emissions:
Today, we will mention only the main contributors to climate carbon dioxide (co2) is the leading ghg that enters the atmosphere through the burning of fossil fuels (coal, oil, and natural gas).
The rest is absorbed by. The faq discusses the relative potency, concentration and expected atmopsheric lifetime. Others, like co2, largely result from natural processes like respiration and from the burning of fossil fuels like coal, oil and gas. Multiple gases contribute to the greenhouse effect that sets earth's temperature over geologic time.
