The South Atlantic may have been one of the first regions to experience a dramatic shift in atmospheric circulation due to anthropogenic climate change, according to an international study.
The research – which combined computer modelling with proxy records dating back 6000 years – suggests that a low-pressure system to the west of the Antarctic Peninsula has had a rising influence over circulation patterns in the South Atlantic since the 1940s, driving southerly air masses over the Falkland Islands and South Georgia.
The circulation pattern had not previously existed for millennia, the scientists believe, implying its emergence was an anthropogenic phenomenon – although they insist more evidence is needed before making any definite claims. […]
