And that methane does not stay in the atmosphere forever, but only for a decade or two. It’s all part of a cycle. If it makes it easier to think about it, here is one way: imagine a world with no humans, no fossil fuels, but stable population of 10 billion cows. These 10 billion cows produce tremendous amounts of methane. Do you expect this methane to warm the climate over next 1000 years? If you do, you’re wrong: if the population has been and will stay stable, the methane that cows emit is just enough to replace the methane decomposing to CO2 and H2O that was previously emitted by the cows. As long as population numbers are constant, the amount of methane in the atmosphere is also constant, and you’ll see no climate warming.
