World’s 1.5C climate target ‘deader than a doornail’, experts say

Scientists say goal to keep world's temperature rise below 1.5C is not going to happen despite talks at Cop29 in Baku

The internationally agreed goal to keep the world's temperature rise below 1.5C is now deader than a doornail", with 2024 almost certain to be the first individual year above this threshold, climate scientists have gloomily concluded - even as world leaders gather for climate talks on how to remain within this boundary.

Three of the five leading research groups monitoring global temperatures consider 2024 on track to be at least 1.5C (2.7F) hotter than pre-industrial times, underlining it as the warmest year on record, beating a mark set just last year. The past 10 consecutive years have already been the hottest 10 years ever recorded.
