UN warns ‘humanity is on thin ice’ in latest climate report. What does it say?

Humanity still has a chance, close to the last one, to prevent the worst of climate change 's future harms, a top United Nations panel of scientists said Monday.

Humanity still has a chance, close to the last one, to prevent the worst of climate change ‘s future harms, a top United Nations panel of scientists said Monday.

But doing so requires quickly slashing carbon pollution and fossil fuel use by nearly two-thirds by 2035, the Intergovernmental Panel on Climate Change said. The United Nations chief said it more bluntly, calling for an end to new fossil fuel exploration and rich countries quitting coal, oil and gas by 2040.

“Humanity is on thin ice – and that ice is melting fast,” United Nations Secretary-General Antonio Guterres said. “Our world needs climate action on all fronts – everything, everywhere, all at once.”

Stepping up his pleas for action on fossil fuels, Guterres not only called for “no new coal” but also for eliminating its use in rich countries by 2030 and poor countries by 2040. He urged carbon-free electricity generation in the developed world by 2035, meaning no gas-fired power plants too.

That date is key because nations soon have to come up with goals for pollution reduction by 2035, according to the Paris climate agreement. After contentious debate, the UN science panel calculated and reported that to stay under the warming limit set in Paris the world needs to cut 60 per cent of its greenhouse gas emissions by 2035, compared with 2019, adding a new target not previously mentioned in the six reports issued since 2018.

“The choices and actions implemented in this decade will have impacts for thousands of years,” the report, said calling climate change “a threat to human well-being and planetary health.”

“We are not on the right track but it’s not too late,” said report co-author and water scientist Aditi Mukherji. “Our intention is really a message of hope, and not that of doomsday.”

With the world only a few tenths of a degree away from the globally accepted goal of limiting warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) since pre-industrial times, scientists stressed a sense of urgency. The goal was adopted as part of the 2015 Paris climate agreement and the world has already warmed 1.1 degrees Celsius (2 degrees Fahrenheit).
