Nicola Jones – How Climate Change Could Jam The World’s Ocean Circulation

Susan Lozier is having a busy year. From May to September, her oceanographic team is making five research cruises across the North Atlantic, hauling up dozens of moored instruments that track currents far beneath the surface. The data they retrieve will be the first complete set documenting how North Atlantic waters are shifting — and should help solve the mystery …

John Michael Greer – CLIMATE CHANGE ACTIVISM: A POST-MORTEM

As I write these words, much of North America is sweltering under near-tropical heat and humidity. Parts of the Middle East have set all-time high temperatures for the Old World, coming within a few degrees of Death Valley’s global record. The melting of the Greenland ice cap has tripled in recent years, and reports from the arctic coast of Siberia …

Retreating sea ice linked to changes in ocean circulation, could affect European climate

Retreating sea ice in the Iceland and Greenland Seas may be changing the circulation of warm and cold water in the Atlantic Ocean, and could ultimately impact the climate in Europe, says a new study by an atmospheric physicist from the University of Toronto Mississauga (UTM) and his colleagues in Great Britain, Norway and the United States. “A warm western …

Economic Collapse Will Limit Climate Change, Predicts Climate Scientist – Till Bruckner

If you think your doctor is hard to understand, try talking to a climate scientist. In late 2014, the World Bank published a remarkable document that should have shaken the international business world. Titled “Turn Down the Heat: Confronting the New Climate Normal“, it drew on 1,300 publications to explore the impacts of a world four degrees centigrade warmer – …

Study: Gulf Stream slower than ever before

The Gulf Stream is the weakest it’s been in the last 1,000 years. And as glacier melt in the Arctic continues to accelerate, the foot of the Atlantic’s most powerful ocean current keeps pressing harder and harder on the brake pedal. A team of researchers recently analyzed an exhaustive catalog of geologic samples — including ice cores, tree rings and …

What’s Going On In The North Atlantic?

The North Atlantic between Newfoundland and Ireland is practically the only region of the world that has defied global warming and even cooled. Last winter there even was the coldest on record – while globally it was the hottest on record. Our recent study (Rahmstorf et al. 2015) attributes this to a weakening of the Gulf Stream System, which is …
