The world is set to breach the 1.5°C global warming threshold within a matter of years, according to a new UN Environment Programme report, with even the most optimistic modelling indicating that warming is likely to temporarily exceed the more ambitious temperature goal agreed under the Paris Agreement.
The report, titled Limiting Overshoot, warns that global temperature rise is 'likely within the next few years' to cross the 1.5°C threshold. It says the best-case scenario now sees warming peak at 1.8°C, above the goal, while most other modelled pathways predict even higher peaks.
