Methane and Frozen Ground | National Snow and Ice …
Methane is a gas made up of one carbon atom and four hydrogen atoms. It''s the same natural gas that some people use to heat their homes, and it also exists naturally in the atmosphere. Scientists worry that if methane increases in the atmosphere, it could cause even more warming than carbon dioxide from the burning of fossil fuels.
