New Hope for Limiting Warming to 1.5°C

Significant emission reductions are required if we are to achieve one of the key goals of the Paris Agreement, and limit the increase in global average temperatures to 1.5°C; a new Oxford University partnership warns.

In a collaboration involving the University of Exeter, University College London, and several other national and international partners, researchers from the University of Oxford's Environmental Change Institute (ECI) and Oxford Martin School have investigated the geophysical likelihood of limiting global warming to "well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C."

Published today in the journal Nature Geoscience, the paper concludes that limiting the increase in global average temperatures above pre-industrial levels to 1.5°C, the goal of the Paris Agreement on Climate Change, is not yet geophysically impossible, but likely requires more ambitious emission reductions than those pledged so far.
