From ABC News, 12 April 2021:
The drought currently plaguing the western USA isn’t the worst drought to plague that region.
Here is more about the climate history of southwestern USA:
From Science magazine, 17 April 2020:
“Paleoclimatic proxies indicate that SWNA experienced many severe swings in hydroclimate before the observed period. In particular, tree-ring records reveal several megadrought events during the Medieval era and subsequent centuries (~850–1600 CE) that dwarfed all droughts in the following 400 years in intensity and duration. These megadroughts were likely associated with cool eastern tropical Pacific sea surface temperatures, which promote an atmospheric wave train that blocks Pacific storms from reaching SWNA. Any attribution of recent drought to anthropogenic climate change must consider this region’s capacity for large internal hydroclimatic variability. . . The tree-ring record serves as an ominous reminder that natural climate variability can drive SWNA megadroughts that are as severe and longer than the 21st-century drought thus far.
According to one author of the above-quoted study, the current drought in the western USA “has been made much worse than it would have been because of man-made action triggering Earth changes.”
With the USA’s western region drying up, surely people will stop moving there.
Sadly, Dr. Rumack is correct. From NBC News, 11 June 2021:
