Humanity is ‘paying a terrible price’ for inaction on global warming, with time running out to correct the course and avoid climate disaster, UN Secretary General Antonio Guterres said Thursday.
A new report by the UN Environment Programme (UNEP) says the next decade is critical in the fight against climate change or any hope of limiting global warming to 1.5C will be lost.
The current pace of climate action would result in a catastrophic 3.1 degrees Celsius of warming this century, UNEP said in its latest Emissions Gap report.
And even if all existing pledges to cut emissions were enacted as promised, global temperatures would soar 2.6C above pre-industrial levels — a still devastating scenario for humanity.
“Either leaders bridge the emissions gap, or we plunge headlong into climate disaster, with the poorest and most vulnerable suffering the most,” said Guterres.
“Around the world, people are paying a terrible price.”
The call to action follows a streak of destructive and deadly extreme weather and comes in a year expected to be the hottest in recorded history.
The world’s poorest have been particularly hard hit, with typhoons and heatwaves in Asia and the Caribbean, floods in Africa, and droughts and wildfires in Latin America.
Nations meeting at the COP29 climate summit next month in Azerbaijan hope to agree on increasing finance for the developing world to cope with climate change.
– ‘Out of time’ –
UNEP’s latest projections blow well past 1.5C, which nations agreed in Paris in 2015 was the safest bet to minimise the worst consequences of a warming planet.
That goal was “still technically possible”, UNEP said — but only with enormous reductions by 2035 in heat-trapping gases caused primarily by burning fossil fuels.
Rather than declining, emissions are still rising, hitting a new record high last year.
Guterres said the world was “playing with fire”.
“But there can be no more playing for time. We’re out of time,” he said.
Keeping 1.5C on track would require a collective effort “only ever seen ever seen following a global conflict”, UNEP said.
Without pulling together “on a scale and pace never seen before… the 1.5C goal will soon be dead,” said UNEP executive director Inger Andersen.
To have a hope of meeting 1.5C, emissions must be slashed 42 percent by 2030 and 57 percent by 2035, UNEP said.
The existing suite of climate commitments — including those contingent on outside financial help — would only cut expected 2030 emissions by 10 percent if implemented as promised.
“These reports are an historical litany of negligence from the world’s leaders to tackle the climate crisis with the urgency it demands, but it’s not too late to take corrective action,” said Tracy Carty from Greenpeace International.
– ‘Bridge the gap’ –
UNEP said advances in solar and wind, two proven and cost-effective technologies, could deliver a steep fall in emissions but investment in such carbon-cutting solutions needed to rise six-fold to meet 1.5C.
Guterres said wealthy nations of the G20 must lead the way.
“Either leaders bridge the emissions gap, or we plunge headlong into climate disaster,” he said.
The world’s 20 largest economies were responsible for nearly 80 percent of global emissions in 2023. The bottom 47 countries accounted for three percent.
The United States was historically the biggest polluter, accounting for 20 percent of global emissions since 1850, when the burning of fossil fuels for energy began in earnest.
The European Union and China accounted for 12 percent each, UNEP said.
A breach of 1.5C is increasingly being seen as inevitable by scientists and policymakers.
But a recent study found that even temporarily exceeding 1.5C before bringing warming back down — a scenario known as an ‘overshoot’ — could cause irreversible consequences for the planet.
