China, Russia and Canada’s current climate policies would drive the world above a catastrophic 5°C of warming by the end of the century, according to a study that ranks the climate goals of different countries.
The US and Australia are only slightly behind with both pushing the global temperature rise dangerously over 4°C above pre-industrial levels says the paper, while even the EU, which is usually seen as a climate leader, is on course to more than double the 1.5°C that scientists say is a moderately safelevel of heating.
The study, published on Friday in the journal Nature Communications, assesses the relationship between each nation’s ambition to cut emissions and the temperature rise that would result if the world followed their example.
The aim of the paper is to inform climate negotiators as they begin a two-year process of ratcheting up climate commitments, which currently fall far short of the 1.5-to-2°C goal set in France three years ago. Link
