New report from @UNEP : 'Limiting Overshoot, Navigating exceedance of 1.5°C and pathways towards return’

Details ⬇️

Global warming is set to cross 1.5°C, pushing climate risks and impacts to increasingly dangerous heights, a new UNEP report warns.  

Predicted impacts include extreme weather and threats to human health and economies.  

Action now can still limit the magnitude and duration of the peak and preserve the possibility of returning to or below 1.5°C through an ‘overshoot, peak, and decline’ pathway
