Global temperature rises to exceed 1.5 Celsius 'within a few years', UNEP says
UN scientists say temperatures could peak at 1.8 C before falling, but only if governments cut emissions fast and remove carbon dioxide at scale.
- On Wednesday, The United Nations Environment Programme issued a report titled Limiting Overshoot, warning that the world will breach the 1.5-degree climate threshold within the next few years and urging governments to accelerate emission cuts and carbon removal.
- Earth is currently 1.4 degrees Celsius above pre-industrial levels, while current policies project temperatures reaching 2.6 degrees by 2100; the United Nations report advises policymakers to prepare for and navigate a future that corrects course.
- Climate scientist Andrew Weaver from the University of Victoria noted the 1.5 limit is not "some magical climate cliff," explaining that global temperatures will follow a hump-shaped path of more warming before cooling by century's end.
- Pacific Island Students Fighting Climate Change director Vishal Prasad said, "We know what 1.5 , and what anything beyond it, means for our future, our families, our culture and our environment," warning of threats to island communities.
- Secretary-General Antonio Guterres demanded an "overshoot of ambition," urging nations to accelerate the phase-out of fossil fuels; every five years of delay adds a tenth of a degree to peak warming, according to Imperial College London climate scientist Joeri Rogelj.

By now it is almost certain: global warming will exceed the threshold of 1.5 degrees more than pre-industrial levels, the limit set by the Paris Agreements of 2015. And much more...
The UN sees little chance of limiting global warming to 1.5 degrees.
For the first time, a key UN report says the 1.5 C global warming threshold is lost
In a strategic retreat in the fight against climate change, the United Nations has acknowledged that Earth has lost its chance to prevent some of the worst of global warming's harms. Officials say the world must now figure out how to get temperatures below the danger zone and back to safety.
Climate ‘Overshoot’ Is Coming—Are We Ready?
We failed to prevent 1.5 degrees of warming, but there is still a choice between doing nothing and allowing warming to continue, say the authors of a new UN study. The post Climate ‘Overshoot’ Is Coming—Are We Ready? appeared first on Truthdig.
