“It’s climate crunch time” when it comes to tackling rising carbon emissions the UN Secretary-General said on Wednesday, stressing that while the need for global action is unprecedented, so too are the opportunities for prosperity and sustainable development.

Choosing the iconic Family Hall of Ocean Life at the American Museum of Natural History in New York to deliver his impassioned plea to grasp the solutions at hand, António Guterres warned that we stand at “a moment of truth”.

“In the case of climate, we are not the dinosaurs. We are the meteor. We are not only in danger – we are the danger. But we are also the solution.”

Citing the latest European Commission Copernicus Climate Change Service report showing last month was the hottest May in history, the UN chief said global emissions need to fall nine per cent every year just to keep the 1.5℃ temperature rise limit above pre-industrial levels alive.

Last year they went up by one per cent.

The UN World Meteorological Organization (WMO) also reported on Wednesday that there is an 80 per cent chance the 1.5℃ limit – the target established in the Paris Agreement in 2015 – will be passed in one of the next five years.

“We are playing Russian roulette with our planet”, said Mr. Guterres. “We need an exit ramp off the highway to climate hell. And the truth is – we have control of the wheel.”
