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.
