The American West’s megadrought deepened so much last year that it is now the driest in at least 1,200 years and is a worst-case climate change scenario playing out live, a new study finds.
“We can actually look at the growth rings on trees and turn that information into information on soil moisture or rainfall going back much further than the observational record would allow us,” said Professor Benjamin Cook, one of the study’s three co-authors.Cook says the growth rings provide a biological snapshot of wet and dry conditions over hundreds of years.
Boat slips lay stranded on dry land as water levels recede at drought-stricken Folsom Lake, Thursday, July 1, 2021 in Folsom, CA. But the region dried up in late 2020 and 2021. All of California was considered in official drought from mid-May until the end of 2021, and at least three-quarters of the state was at the highest two drought levels from June through Christmas, according to the U.S. drought monitor.
“I was wondering if we’d ever see a year like 2002 again in my life and in fact, we saw it 20 years later, within the same drought,” Williams said. The drought levels in 2002 and 2021 were a statistical tie, though still behind 1580 for the worst single year. The study “is an important wake-up call,” said Jonathan Overpeck, dean of environment at the University of Michigan, who wasn’t part of the study. “Climate change is literally baking the water supply and forests of the Southwest, and it could get a whole lot worse if we don’t halt climate change soon.”
