A revelation about trees is messing with climate calculations
I find this stuff absolutely incredible. I’ve been learning recently about this phenomenon  being known, but not understood.<p>The most obvious indication was that logging leads to less rain, so it seems as though trees actually cause rain.<p>One theory was that turbulence in the air above forests could trigger precipitation, and while that might still be a factor, this explanation is very clean and easy to understand.<p>This is awesome in any case. I’ve been wanting to use the “trees cause rain” point in discussions about forestry and hydrology, but had to be careful because we only had correlations as far as I knew. This doesn’t fully solve that, but certainly helps explain and create a causative link.<p>Also just incredible how evolution works. Of course trees cause rain, haha. I wonder if other plants such as grasses in vast plains have their own tricks to seed rain, or if their strategy is surviving drought extremely well. It’s all cool either way.
