The Gulf Stream is the global conveyor belt for cold water and warm water and is part of the large-scale ocean circulation that plays a key role in keeping the climate at balance and Europe warm. Global warming may change it forever with unforeseeable consequences but if it changes, we are in for a heap of trouble so it is worrying that scientists at the Potsdam Institute for Climate Impact Research in Germany are warning that it is doing exactly that.
Prof Stefan Rahmstorf explains that the currents that bring warm Atlantic water northwards towards the pole, where they cool, sink and return southwards, is the most significant control on northern hemisphere climate outside the atmosphere but the system has weakened by 15% since 1950, thanks to melting Greenland ice and ocean warming making sea water less dense and more buoyant.
'From the study of past climate, we know changes have been some of the most abrupt and impactful events in the history of climate' said the Professor explaining that a collapse in the Gulf Stream would mean severe winters and increase summer heatwaves.
Gulf Stream current at its weakest in 1,600 years, studies show which is as far back as they can go and Greenland’s massive ice cap is melting at the fastest rate for at least 450 years which will continue to further weaken the Gulf Stream.
Well done humans, you idiots.
