Between 2005 to 2015, surface melt off ice caps and glaciers of the Queen Elizabeth Islands grew from an average of three gigatons to 30 gigatons
The Greenland Ice Sheet isn’t the only place melting under a thickening blanket of heat-trapping greenhouse gases. A new study shows that Canada’s Arctic glaciers are also shedding ice at a rapidly increasing rate, making them a big factor in global sea level rise.
In a new study, glaciologists with the University of California, Irvine said that, between 2005 to 2015, surface melt off ice caps and glaciers of the Queen Elizabeth Islands grew by 900 percent, from an average of three gigatons to 30 gigatons per year, according to findings published last week in the journal Environmental Research Letters.

Ice loss has huge implications for regional water resources
FRISCO — Glaciers in the Tien Shan, Central Asia’s largest mountain range, have lost 27 percent of their mass and 18 percent of their area during the last 50 years, shedding an average of 5.4 gigatons of ice per year.
By 2050 about half of Tien Shan’s glacier volume could be depleted, a team of scientists estimated in a new paper published in the current online issue of Nature Geoscience.
FRISCO — Global warming is melting Alaska’s glaciers so fast that the water would cover the entire state a foot deep every seven years, scientists report in a new study. The melting won’t slow down anytime soon and will be a major factor in global sea level rise, the researchers said.
“The Alaska region has long been considered a primary player in the global sea level budget, but the exact details on the drivers and mechanisms of Alaska glacier change have been stubbornly elusive,” said Chris Larsen, a research associate professor with the Geophysical Institute at the University of Alaska Fairbanks.

Snowfall rates would need to double to slow glacial retreat
By Summit Voice
SUMMIT COUNTY — After significant warming during half century, about 10 percent of Bhutan’s glaciers are likely to disappear within the next few decades — even if regional and global temperatures were to stabilize at current levels.
Rupper’s most conservative findings the amount of melt water coming off these glaciers could drop by 30 percent. Increasing temperatures are just one culprit behind glacier retreat. A number of climate factors such as wind, humidity, precipitation and evaporation can affect how glaciers behave. With some Bhutanese glaciers as long as 13 miles, an imbalance in any of these areas can take them decades to completely respond. Continue reading “Global warming: Bhutan’s glaciers at risk”→
