An interesting look at the NASA Megadrought Prediction for the 21st Century that used tree ring data to understand past droughts. The NASA scientists also used climate models incorporating soil moisture data to estimate the risk of future drought. The NASA scientists are sure to add to the heated discussion of mankind’s effect on climate change with this data. In case you think I’m really worried about this I tend to side with George Carlin and his views on the environment and Saving The Planet.
