Last week I had the opportunity to attend a lecture by Johann Rockstr\u00f6m explaining his most recent Nature commentary about tipping points<\/a> “too risky to\u00a0 bet against”.<\/p>\n

The Intergovernmental Panel on Climate Change (IPCC) introduced the idea of tipping points two decades ago. At that time, these \u2018large-scale discontinuities\u2019 in the climate system were considered likely only if global warming exceeded 5\u2009\u00b0C above pre-industrial levels. Information summarized in the two most recent IPCC Special Reports (published in 2018 and in September this year) suggests that tipping points could be exceeded even between 1 and 2\u2009\u00b0C of warming.<\/p><\/blockquote>\n

This is a cruel message in particular as probably already one tipping point has been passed @ the Amundsen Sea embayment of West Antarctica. There is a thick ice sheet of about 3 km which forms one of the three major ice-drainage basins of the West Antarctic Ice Sheet. And the ice is melting rapidly – with the tipping point having been passed in 1996.<\/p>\n

The Amazon is burning right now<\/a> \u2014 the world\u2019s largest rainforest. Estimates of the Amazon tipping point ranges between 20% and 40% deforestation.<\/p>\n
