First time I've heard that methane decays so fast. Doesn't this dramatically reduce the practical warming effect of methane?

- contravariant 10y agoIt does, but according to the Wikipedia article the '25 times' figure seems to have taken that into account. Methane has a 25 times (or 34 times according to more recent estimates) larger effect than an equivalent mass of CO2 over 100 years. When measured over the first 20 years this rises to 70~80 times.
