Arctic melt ponds form when meltwater clogs ice pores

When spring comes to the Arctic, the breakup of the cold winter ice sheets starts at the surface with the formation of melt ponds. These pools of melted snow and ice darken the surface of the ice, increasing the amount of ...

Radar reveals meltwater's year-round life under Greenland ice

When summer temperatures rise in Greenland and the melt season begins, water pools on the surface, and sometimes disappears down holes in the ice. That water may eventually reach bedrock, creating a slipperier, faster slide ...

Historical records may underestimate global sea level rise

New research published in Geophysical Research Letters shows that the longest and highest-quality records of historical ocean water levels may underestimate the amount of global average sea level rise that occurred during ...

Greenland sets record temperatures, ice melts early

Temperature records were broken in Greenland this year after parts of the territory's vast ice sheet began melting unusually early, the Danish Meteorological Institute (DMI) said Tuesday.

2016 climate trends continue to break records

Two key climate change indicators—global surface temperatures and Arctic sea ice extent—have broken numerous records through the first half of 2016, according to NASA analyses of ground-based observations and satellite ...

NASA science flights target melting Arctic Sea ice

This summer, with sea ice across the Arctic Ocean shrinking to below-average levels, a NASA airborne survey of polar ice just completed its first flights. Its target: aquamarine pools of melt water on the ice surface that ...

Operation IceBridge completes 2016 Arctic spring campaign

Operation IceBridge, NASA's airborne survey of polar ice, ended its eighth spring Arctic campaign on May 21. During their five weeks of operations, mission scientists carried out six research flights over sea ice and ten ...
