Why do mountaintops stay snowy?
The answer has to do with the air we breathe and that bright white snowpack, as an atmospheric scientist in Colorado explains.

âColorado has warmed at a faster rate than the global average and is expected to continue to warm...Having said that, not every winter going forward is going to be as warm as this winter. And, in fact...I think this winter will be considered a much-warmer-than-normal winter for some time to come.â

"We look ahead to March & April as the time when big storms are possible and the deficits can be made up. Unfortunately, this year has been just the opposite: Instead of much-needed snowstorms, weâre in an unprecedented March heat wave that is accelerating the melting of what little snow is there."

Colorado faces limited water supply after record-low snowpack
As of March 25, averaged across 115 stations in Coloradoâs mountains, the snow water equivalent was just 38% of the 1991-2020 average. This represents the lowest snowpack in more than 40 years â and p...
