Does natural plant decomposition release more greenhouse gases than burning
I understand that all plant matter releases CO2 as it decomposes and also when it burns in, for example, a forest fire. My assumption, upon which this question is based, is that the CO2 release is the ...

Why do greenhouse gases affect ocean temperature so much?
As I understand it, greenhouse gases absorb infrared radiation from the sun. Much of that radiation would otherwise continue and be absorbed on the planet surface in the ocean or on land. If CO2 ...
