With Warmer Climates, Snowmelts Are Reducing Water Availability in Communities

Contrary to what you may think, warmer climates create a slower and earlier snowmelt during the winter. The snow starts melting sooner in the season and earlier during the day, as days are shorter. With a slower melt, the amount of water reaching the ground where it doesn’t evaporate is reduced so most of the snowmelt doesn’t create a runoff and never reaches downstream.

University of Nevada – Reno discovered that with a reduced runoff, there is less water available for drinking and agriculture as the snowmelt never reaches reservoirs. Nearly 60 million people depend on snowmelt for their water supply so with continued warmer climates, water availability will be greatly reduced.
