Cryosphere decline continues, Northern Hemisphere snow and glacier loss accelerates: IPCC

All components of the cryosphere have been in decline over the past few decades (see figure 4.25), with North­ern Hemisphere spring snow cover continuing to decrease in extent, and glaciers losing mass and contributing to sea level rise throughout the 20th century. The strong and significant changes reported to the cryosphere in IPCC’s last major… Read More Cryosphere decline continues, Northern Hemisphere snow and glacier loss accelerates: IPCC

Long term declines in mountain snowpack continue: IPCC

Globally, long term declines in mountain snowpack have been observed and are further projected over the past three decades, particularly at lower, warmer elevations.  Increasing air temperature in mountainous regions will raise snow lines and major reductions in snow cover are projected for mid-latitudes in general by the end of this century with lower, warmer… Read More Long term declines in mountain snowpack continue: IPCC

Northern hemisphere snow cover declining 1.3% per decade: UNEP

The average monthly extent of snow cover in the Northern Hemisphere has declined 1.3% per decade, with the greatest losses in the spring and summer, over the last 40 years. In the last 50 years, the U.S. snow season has become 16 days shorter, with peak run off over a week earlier.
