A new study is causing shockwaves amongst the climate alarmism community.
According to Slate.com, we are about to enter the “The United States of Megadrought.” The article shows the following graphs of historical, current, and projected moisture balances in the Central Plains and Southwest regions (negative numbers indicate dry conditions, with the magnitude indicating the degree of dryness).Look closely at these plots. First off, both regions were generally drier in the past than over the last several decades. In addition, there appears to be no clear anthropogenic climate change signature in either of these datasets. All we appear to be seeing of late is variability well within the historical record.
Yet the climate modeling efforts suggest we are about to go off the megadrought cliff in the near future. Who knows? Predictions cannot be refuted until they fail to pass. But given the poor performance of climate models to date, we should be very skeptical of any climate modeling projections — and we certainly should not be basing any policy on the models.
