‘Disastrous’ energy policies of China, Russia, Brazil and Australia could stoke 5C rise in temperatures if adopted by the rest of the world

A key group of leading G20 nations is committed to climate targets that would lead to disastrous global warming, scientists have warned. They say China, Russia, Brazil and Australia all have energy policies associated with 5C rises in atmospheric temperatures, a heating hike that would bring devastation to much of the planet.

The analysis, by the peer-reviewed group Paris Equity Check, raises serious worries about the prospects of key climate agreements being achieved at the Cop26 summit in Glasgow in three months. The conference – rated as one of the most important climate summits ever staged – will attempt to hammer out policies to hold global heating to 1.5C by agreeing on a global policy for ending net emissions of greenhouse gases by 2050.
