Western communities are facing effects of a warming climate with slower and earlier snowmelt reducing streamflows and possibly the amount of water reaching reservoirs used for drinking water and agriculture, according to a study published in July."As the climate warms, there is actually a slower snowmelt – both in timing and rates, which makes for a less efficient streamflow," Adrian Harpold, ecohydrologist at the University of Nevada, Reno said. Harpold, who initiated the study two years ago at the University of Colorado Boulder, is a co-author of the paper published in AGU publications Geophysical Research Letters.
