Global average temperature rise of 1.5c likely to be reached 10 years early

 The planet is odds-on to hit 1.5C of global warming within 20 years, the world’s leading climate scientists will warn in a milestone report tomorrow. The paper, produced by the UN’s Intergovernmental Panel on Climate Change (IPCC), is the starkest warning yet about the speed and scale of warming. Experts said the report would paint a “devastating”

The document is predicted to trigger a “turning point” in the run-up to the Cop26 climate conference in Glasgow in November. Tomorrow’s report, produced by 200 scientists from 60 countries, is the first comprehensive assessment of the physical science of climate change since 2013. An interim report, published in 2018, said global warming was likely
to reach 1.5C between 2030 and 2052.

According to insiders who have seen the final document, the report brings this window forward by a decade to between 2021 and 2040. The report is expected to detail the risk of “tipping points”, in which climate change becomes hard to reverse. The melting of glaciers and ice sheets, for example, may create “feedback
loops” in which global warming spirals out of control. “That sensitivity means you can be too late,” Rivett-Carnac said.

“A lukewarm agreement [at Glasgow] that kicks the can down the road and solves some problems, has become, in a way, as much something to be avoided as not reaching the outcome you want.”
