Global temperature rises to exceed 1.5 Celsius 'within a few years', UNEP says
UNEP says the 1.5C limit will be breached within years under current policies, and returning below it would require rapid cuts and large-scale carbon removal.
- 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.

<p>The Earth will soon exceed the safe temperature limit — the UN recognizes the loss of a chance to avoid part of the effects of warming. The world can still lower its temperature after exceeding the limit.</p>
On Wednesday, the UN presented ways to contain global warming once the very symbolic threshold of +1.5°C has been crossed.
The World Will Overshoot 1.5°C and Must Now Remove Carbon, United Nations Says
Humanity is certain to exceed the warming limit set by the Paris Agreement, a legally binding treaty meant to cap the world’s carbon emissions, according to a new report from the United Nations Environment Programme (UNEP). Now, to reduce severe threats to human health, food security, water supplies, and more, societies will need to reach net-negative greenhouse gas emissions by not only cutting those emissions, but expanding carbon dioxide remo…
