09\/09\/2022 – Multiple climate tipping points could be triggered if global temperature rises beyond 1.5\u00b0C above pre-industrial levels, according to a major new analysis published in the journal Science. Even at current levels of global heating the world is already at risk of passing five dangerous climate tipping points, and risks increase with each tenth of a degree of further warming. An international research team synthesised evidence for tipping points, their temperature thresholds, timescales, and impacts from a comprehensive review of over 200 papers published since 2008, when climate tipping points were first rigorously defined.<\/div>\n

The research, published in advance of a major conference \u201cTipping Points: from climate crisis to positive transformation\u201d at the University of Exeter (12-14th September), concludes human emissions have already pushed Earth into the tipping points danger zone. Five of the sixteen may be triggered at today\u2019s temperatures: the Greenland and West Antarctic ice sheets, widespread abrupt permafrost thaw, collapse of convection in the Labrador Sea, and massive die-off of tropical coral reefs. Four of these move from possible events to likely at 1.5\u00b0C global warming, with five more becoming possible around this level of heating.<\/p>\n

Lead author David Armstrong McKay from Stockholm Resilience Centre, University of Exeter, and the Earth Commission says, \u201cWe can see signs of destabilisation already in parts of the West Antarctic and Greenland ice sheets, in permafrost regions, the Amazon rainforest, and potentially the Atlantic overturning circulation as well.\u201d<\/b><\/p>\n

“The chance of crossing tipping points can be reduced by rapidly cutting greenhouse gas emissions”<\/strong><\/p>\n

\u201cThe world is already at risk of some tipping points. As global temperatures rise further, more tipping points become possible.\u201d he adds. \u201cThe chance of crossing tipping points can be reduced by rapidly cutting greenhouse gas emissions, starting immediately.”<\/p>\n
