Ice Loss During Antarctic Cold Reversal May Spell Trouble for WAIS Collapse

By | Abrupt changes, Antarctica, Glaciers, Greenland, Gulf Stream, ice sheet, Oceans, underice, West Antarctic Ice Sheet

Fifty-two feet of sea level rise occurred in 400 years, 14,500 years ago with collapse conditions similar to today. We were coming out of the last ice age then, but then, forcing was thousands of times less than today. Our climate’s most meaningful and common…

West Antarctic Ice Sheet (WAIS) Collapse: The Latest Case for Zero Warming

By | Abrupt changes, Antarctica, Climate Policy, Climate Reform, ice sheet, Oceans, Policy, Sea Level Rise, Strategy, underice

New research has for the first time defined the tipping point between a stable WAIS and an Antarctica that collapses uncontrollably. Potsdam Institute researchers (Levermann and Feldmann) tell us is that if we do not return our oceans to their preindustrial temperature by 2050, we…

Greenland: Jakobshavn New World Speed Record, Hundreds of Deeply Incised Underice Valleys Beneath Outlet Glaciers

By | Glaciers, Greenland, ice sheets, submarine channel, underice

The North Atlantic is warming and  Greenland’s ice loss has quadrupled in the last 20 years. Warm water is getting under the floating edges of outlet glaciers and causing thinning which in-turn causes the glaciers to speed up. New research has identified another and  possibly…
