The world is likely to temporarily cross the 1.5°C global warming limit within years, exposing ecosystems and communities to severe climate risks, a UNEP report said. However, rapid emissions cuts, carbon removal and stronger climate action could help bring temperatures back below the threshold, keeping Paris Agreement goals within reach.
The world is set to cross the 1.5°C global warming threshold, likely within the next few years, exposing people and ecosystems to increasingly dangerous climate impacts, according to a new UN Environment Programme (UNEP) report. However, it says temperatures can still be brought back below the threshold and the goals of the Paris Agreement achieved.
The report, Limiting Overshoot, identifies an "overshoot, peak and decline" pathway as the best remaining option. Under this approach, temperatures would temporarily exceed 1.5°C, peak and then decline as countries rapidly cut greenhouse gas emissions and eventually remove more carbon dioxide from the atmosphere than they emit.
A Narrower Climate Path
"This summer's scorching heat, raging wildfires and deadly floods are a warning of what lies ahead. We must make the overshoot above 1.5 degrees as small and short as possible. That demands an overshoot of ambition," UN Secretary-General António Guterres said.
