Too Hot, Too Wet, Too Dry
A week ago, I wrote of new research indicating that global warming has resulted in increased water flow in freshwater systems around the globe. In other words, there’s increased flooding.
This week, there’s news of scientific research that might sound contradictory at first: Huge patches of the Earth have become almost completely dried out, and more areas are moving in that direction Actually, it’s part of the same process that’s brought extra flooding.
The process of evapotranspiration is a part of the water cycle that brings water from the surface up into the air and back down as rain again. The thing is that, while water evaporates or transpires wherever it touches the air, even in very cold places, water does not fall evenly. So, as global temperature increases, the unevenness of fresh water distribution is moving into even higher contrast.
For those of you who are Cold Earthers, still not believing in global warming, keep in mind that this effect was predicted by scientific climate models years ago. Those models, despite industry claims to the opposite, have proved to be remarkably accurate.
