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…
