UN scientists have unveiled a plan that they believe can limit the root causes of dangerous climate change.
A key UN body says in a report that there must be “rapid, deep and immediate” cuts in carbon dioxide (CO2) emissions.
Global emissions of CO2 would need to peak within three years to stave off the worst impacts.
Even then, the world would also need technology to suck CO2 from the skies by mid-century.
After a contentious approval session where scientists and government officials went through the report line by line, the UN’s Intergovernmental Panel on Climate Change (IPCC) has now published its guidance on what the world can do to avoid an extremely dangerous future.
First, the bad news – even if all the policies to cut carbon that governments had put in place by the end of 2020 were fully implemented, the world will still warm by 3.2C this century.
This finding has drawn the ire of the UN Secretary General Antonio Guterres.
