The science behind how forests impact weather is still developing, so I can’t make wild claims like I want to. Yet the evidence is extremely compelling. Trees seem to induce rain, reduce turbulence from winds, and as this article mentions, cool the air far more than we thought.

Trees seem to be—unsurprisingly—specialist organisms in the art of maximizing local hydrological features. They help create wetter environments so more trees can live there, and things can get a little more wet still, for more trees, then more water, and so on.

The research I’ve read is mostly along the lines of “we’ve observed these really interesting patterns and we suspect these are the underlying mechanisms”, but as I recall, proving the cause and effect of such large scale phenomenons isn’t trivial. I’m also not someone who researches this stuff, so my take on it is essentially irrelevant. The bottom line is: lots of evidence and research supports your observation, and it’s an extremely interesting field of research. I think it’s the key to making life better for a lot of life on the planet.
