> But where does it get wetter? It's not helpful if the air over the oceans gets wetter while the air over dry regions gets dryer.
On average, global land areas have seen more precipitation since 1950. But even as much of the world has become wetter, some regions have become drier.
Absolutely or relatively? If the dry areas get 2 less inches of rain per year and the wet areas get 2 inches more, it's a much bigger impact on vegetation going from 12 to 10 inches of rain per year than going from 120 to 122 inches per year.
