Atlantic Ocean circulation nearing ‘devastating’ tipping point, study finds

Sea levels in the Atlantic would rise by a metre in some regions, inundating many coastal cities. The wet and dry seasons in the Amazon would flip, potentially pushing the already weakened rainforest past its own tipping point. Temperatures around the world would fluctuate far more erratically. The southern hemisphere would become warmer. Europe would cool dramatically and have less rainfall. While this might sound appealing compared with the current heating trend, the changes would hit 10 times faster than now, making adaptation almost impossible. 

"What surprised us was the rate at which tipping occurs," said the paper's lead author, René van Westen, of Utrecht University. "It will be devastating."…
