This isn't obvious to me at all.
It's true that rainfall causes trees (and that drought can kill them). But it's less obviously true that trees (in massive numbers) can affect the regional climate enough to cause rain. They do this by pumping water out of the ground and increasing humidity, by changing wind patterns, etc.
When trees cause rain, it's a lesser effect than when rain causes trees, but it's still there.
So when someone tells me that it's obvious that hundreds of thousands of tons of frozen, powdered water laying on the ground doesn't cause the temperature, I have to wonder if they're a retard.
