Mt. Everest will lose 70 percent of its permafrost cover by the year 2100, Study

Data from a new study tells us that more than 70% of the glacier volume from the Mount Everest Region could melt by 2100 if current trends in climate change keep going as predicted.

If greenhouse-gasses are allowed to continue rising, the next decades could mean a dramatic change for glaciers in the Himalayan region. For more information, you can view the in The Cryosphere.

The numbers don’t tell a good story. According to researchers from the Netherlands, Nepal, and France, glacier volume could reduce by a whopping 99% at worst by the year 2100.

These numbers depend on how fast greenhouse-gasses rise, affecting snow, rain, and temperature levels in the area.

According to Joseph Shea leader of the study and glacier hydrologist at the International Centre for Integrated Mountain Development in Nepal, “The signal of future glacier change in the region is clear: continued and possibly accelerated mass loss from glaciers is likely given the projected increase in temperatures.”

“Our results indicate that these glaciers may be highly sensitive to changes in temperature, and that increases in precipitation are not enough to offset the increased melt.”

A reduction of glacial volume could also adversely affect the region, harming agriculture and hydropower while reducing available water.

Debris for the glacial retreat could also dam lakes, setting up devastating floods that can get triggered by avalanches and earthquakes.
