Wildfire and drought are shrinking California snowpack
For decades, Californians have depended on the reliable appearance of spring and summer snowmelt to provide nearly a third of the state’s supply of water. But as the state gets drier, and as wildfires climb to ever-higher elevations, that precious snow is melting faster and earlier than in years past — even in the middle of winter. That’s posing a threat to the timing and availability of water in California, according to authors of a recent study in the journal Geophysical Research Letters, which found that the effects of climate change are compounding to accelerate snowpack decline. … There are several systems at work to create this unwanted effect, including climate change, forest management practices and worsening drought and wildfires. In 2020 and 2021, the state saw a nearly tenfold increase in wildfire activity in snowy places compared with the years 2001-19, according to the study.
