Understanding Ice Loss in Earth’s Coldest Regions

How do ice sheets melt in places where surface conditions are too cold for melting? Glaciers in the McMurdo Dry Valley rarely are observed to be actively melting, yet runoff from these glaciers feeds streams, lakes, and associated ecosystems in the valleys, which are among the coldest and driest ecosystems on Earth. The processes generating

Antarctic Coastline Images Reveal Four Decades of Ice Loss to Ocean

Part of Antarctica has been losing ice to the ocean for far longer than had been expected, satellite pictures reveal. A study of images along 2000km of West Antarctica’s coastline has shown the loss of about 1000km2 of ice – an area equivalent to the city of Berlin – over the past 40 years. Researchers

Study Finds Ice Isn’t Being Lost from Greenland’s Interior

Scientists studying data from the top of the Greenland ice sheet have discovered that during winter in the center of the world’s largest island, temperature inversions and other low-level atmospheric phenomena effectively isolate the ice surface from the atmosphere — recycling water vapor and halting the loss or gain of ice. A team of climate

Ice Loss Accelerating in Greenland’s Coastal Glaciers

HANOVER, N.H. – Surface meltwater draining through and underneath Greenland’s tidewater glaciers is accelerating their loss of ice mass, according to a Dartmouth study that sheds light on the relationship between meltwater and subglacial discharge. The findings appear in the journal Annals of Glaciology. A PDF is available on request. Greenland has the potential to

Cryosat Finds Sharp Increase in Antarctica’s Ice Losses

Three years of observations from ESA’s CryoSat satellite show that the Antarctic ice sheet is now losing 159 billion tonnes of ice each year – twice as much as when it was last surveyed.
