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…

There All Along: “Exceptional” Slowdown of the Gulf Stream From Greenland Melt

By | Abrupt changes, Arctic, Glaciers, Greenland, Gulf Stream, Oceans, Truthout.org

First Published on Truthout, April 13, 2015. The Gulf Stream plays an immensely important role in moderating the climate of eastern North America and Europe. Moreover, Greenland melt impacts ocean current processes in the North Atlantic. For years, contradictory research has alternately said the Gulf…

One Hundred Times Faster than Anything in 65 Million Years: The Speed of Climate Change

By | clathrates, Climate Catastrophes, Extinction events, Methane, Oceans, Shifting Ecology, Temperature, Uncategorized

Climate change projected by the IPCC 2013 report under the business as usual scenario (RCP8.5) projects climate change in the next 100 years to be as big as the Paleocene/Eocene Thermal Maximum extinction event 56 million years ago. Changes today however are happening 100 times…

North Atlantic Current Change in Mid 20th Century

By | Oceans

These biogeochemists are getting smarter everyday. Now they have determined how to identify different species of nitrogen that have been created in different areas.  Tropical waters create one kind of nitrogen, polar waters create another. Deep water corals utilize nitrogen in growth.  These researchers have…
