Climate Science Basics: Why Will Dry Areas Get Drier & Wet Areas Get Wetter (Video)
We talk a lot about how climate change is likely to make dry areas (especially those in sub-tropical zones) even drier in coming years, while those wet areas in the sub-polar and equatorial regions are likely to become even wetter. If all that's tough for you to visualize or fully grasp the atmospheric science behind it, then this video from NOAA (h/t Climate Progress) is just the thing.
Spend the next 4 minutes, 22 seconds getting down some climate science basics. The video is pretty self-explanatory.
