Human-related Sources. In the United States, the largest methane emissions come from the decomposition of wastes in landfills, ruminant digestion and manure management associated with domestic livestock, natural gas and oil systems, and coal mining.
We're not sure how much methane is trapped in methyl clathrates, or how much is in danger of escaping. The other major source of methane in the Arctic is the organic matter frozen in permafrost. This is the source of methane that I study. The organic matter in permafrost contains a lot of carbon. It is made of dead plants and animals that have been frozen deep in permafrost for thousands of years.
