Early snowmelt a trend in Western Canadian mountains: study
and United States mountain ranges is causing drier summers and increasing wildfire risk, says a new study from the University of Colorado Boulder.
“We actually saw some of the strongest signals up in the Canadian Rockies, by way of this decrease in snowfall and then earlier snowmelts and rainfall generation,” Hale said in an interview.Snowmelt serves as the primary water resource in western mountain regions, the study says. The ranges store snow throughout the winter, which then melts during spring and summer months when demand for water peaks.
“The snowmelts are providing most of the downstream water resources, such that if there is more snowmelt occurring earlier in the year, that means there will be less available for later in the year,” she said.
