Greenland’s Melting Ice Nears a ‘Tipping Point,’ ...

For scientific papers on AGW, record happenings in the Arctic and the Greenland, Himalayan and Antarctic icesheets. Also weatherstorms and higher than average rainfalls and other extreme weather events.

Open to guest posting.

Ashton Mining mines diamonds somewhere in WA. Tiny ones for industrial use, the odd jewelry-grade stone.

Looks like warm sea water is melting some of Greenland’s ice sheet from below:

Published in their final form last week in the journal Geophysical Research Letters, the maps draw on a variety of data sources, including satellite radar and aerial imagery, as well as special sonar data collected on ship expeditions to the front of the ice sheet. (An earlier, although nearly identical, version of the paper was published online in September.)

Included in the new paper are some of the most detailed data yet on the depths of the canyons and fjords scarring the Greenland coast, which carry water in from the sea to lap against the ice. The results suggest that the western and northern regions of Greenland are most exposed to the influence of ocean water. Out of 139 ocean-touching glaciers the team identified, they also found that 67 rest in waters 200 meters (about 650 feet) or more below sea level, where warm water is typically found—at least twice as many as previously thought.

I know Jacobshavn has been hit by cold water and has advanced tho still losing net ice (thread: Denier’s Delight.)

Leaves plenty of other Greenland coasts.
