CNN —Snowfall is declining globally as temperatures warm because of human-caused climate change, a new analysis and maps from a NOAA climate scientist show.
There has already been a 2.7% decline in annual global snowfall since 1973, according to Brettschneider’s analysis of data from the European Union’s Copernicus Climate Change Service.
The increase in snowfall in the Northeast seen on the maps illustrates the complicated nature of changing precipitation patterns with climate change, scientists told CNN.
“Even though the total snowfall trend was positive, the days per year with snowfall trend is negative,” Brettschneider told CNN.
Managing water with less snowUnderstanding the implications of less snowfall on the global water supply is far more complicated than simply saying less snow falling means less available water, Mankin said.
