• AIR QUALITY | CLIMATE CHANGE: New research found that dust deposition speeds up snowmelt in Utah's Wasatch Mountains. Scientists found that a single dust storm on April 13, 2017, deposited half of all dust for the season. The additional sunlight absorbed by the dust-darkened snow surface led to snow melting a week earlier., 12/21/2018
