Even after a year and a half of wet weather, research shows the American West has experienced the driest 25-year period in 1,200 years. When might the megadrought end?
Three years ago, climate researchers shocked drought-weary Californians when they revealed that the American West was experiencing its driest 22-year period in 1,200 years, and that this severe megadrought was being intensified by global warming. Now, a UCLA climate scientist has reexamined the data and found that, even after two wet winters, the last 25 years are still likely the driest quarter-century since the year 800.
” “It's important to recognize that even the megadroughts in our tree-ring reconstruction had extremely wet years within them, wet years like 2023,” Williams said. “Megadroughts can take brief breaks.” Whether this megadrought continues or eases will become clearer over the next year or two, he said. If wetter-than-average conditions continue, he said, it might be the case that the megadrought already ended after 23 years in 2023.
