What If It’s Too Warm to Snow? Water Managers Across the West Need to Adapt, Report Says

Arizona and the West could see their water supplies drop by as much as 30% by the middle of the century as warmer temperatures lead to less snowfall, reducing runoff into rivers and reservoirs, changing vegetation cover and altering wildlife habitat.

Those are the findings of a team of researchers led by Erica R. Siirila-Woodburn and Alan M. Rhoades at the Lawrence Berkeley National Laboratory, who published a paper looking at the likelihood of a “low-to-no snow” future. Their analysis, published in the journal Nature Reviews Earth and Environment, also estimates when and where to expect the effects of a low-to-no snow climate disaster.
