How does methane causes global warming?

Carbon dioxide usually gets most of the blame for global warming, but a dramatic increase in methane gas emissions is worrying scientists. Global warming is causing the world's wetlands to produce more methane gas — which in turn is causing more global warming. read more

While methane is a more potent greenhouse gas than CO2, there is over 200 times more CO2 in the atmosphere. Hence the amount of warming methane contributes is 28% of the warming CO2 contributes. read more

Methane Causes Vicious Cycle In Global Warming Carbon dioxide usually gets most of the blame for global warming, but a dramatic increase in methane gas emissions is worrying scientists. Global warming is causing the world's wetlands to produce more methane gas — which in turn is causing more global warming. read more

Methane (CH4) is a greenhouse gas and causes warming the same way that CO2 does. It absorbs radiation emitted from the surface and re-emits that radiation in all directions with some of the radiation returning to the surface where it is absorbed and converted to kinetic energy or heat. read more
