UN Environmental Programme Admits 1.5°C Warming Limit Is No Longer Achievable
The United Nations Environmental Programme has for the first time acknowledged that the 2015 Paris Agreement target of limiting warming to 1.5°C above pre-industrial levels can no longer be met. UNEP's new framework instead focuses on minimizing both the duration and magnitude of overshoot past that threshold, requiring steep near-term emissions cuts alongside large-scale removal of hundreds of gigatonnes of carbon dioxide from the atmosphere before 2100.
