PARIS: On the eve of crunch UN climate talks, the EU’s climate monitor says this year is “virtually certain” to be the hottest in recorded history with warming above 1.5C.

The Copernicus agency said the world was passing a “new milestone” of temperature records that should be a call to accelerate action to cut planet-heating emissions at the COP29 negotiations in Azerbaijan next week.

Last month, marked by deadly flooding in Spain and Hurricane Milton in the United States, was the second hottest October on record, with average global temperatures second only to the same period in 2023.

“Humanity’s torching the planet and paying the price,” said United Nations Secretary-General Antonio Guterres in a recent speech, listing a string of calamitous floods, fires, heatwaves and hurricanes across the world this year so far.

“Behind each of these headlines is human tragedy, economic and ecological destruction, and political failure,” Copernicus said 2024 would likely be more than 1.55 degrees Celsius (2.8 degrees Fah­renheit) above the 1850-1900 average the period before the industrial-scale burning of fossil fuels.

This does not amount to a breach of the Paris deal, which strives to limit global warming to below 2C and preferably 1.5C, because that is measured over decades and not individual years. “It is now virtually certain that 2024 will be the warmest year on record and the first year of more than 1.5C above pre-industrial levels,” said Cope­rnicus Climate Change Ser­vice (C3S) Deputy Director Samantha Burgess.

“This marks a new milestone in global temperature records and should serve as a catalyst to raise ambition for the upcoming Climate Change Conference, COP29.”

The UN climate negotiations in Azerbaijan, taking place in the wake of the US election victory by Donald Trump, will set the stage for a new round of crucial carbon-cutting targets.

Trump, who has repeatedly called climate change a “hoax”, pulled the US out of the Paris Agreement during his first presidency. While President Joe Biden took the US back in, Trump has threatened to withdraw again.

Meanwhile, average global temperatures have reached new peaks, as have concentrations of planet-heating gases in the atmosphere.

Scientists say the safer 1.5C limit is rapidly slipping out of reach while stressing that every tenth of a degree in temperature rises heralds progressively more damaging impacts.

Last month the UN said the current course of action would result in a catastrophic 3.1C of warming this century, while all existing climate pledges taken in full would still amount to a devastating 2.6C temperature rise.

And in a report on Thursday, the UN warned that the amount of money going to poorer countries for adaptation measures was barely one-tenth of what they needed to spend on disaster preparedness.

In a month of weather extremes, October saw abo­ve-average rainfall across swathes of Europe, as well as parts of China, the United States, Brazil and Australia, Copernicus said. The US is also experiencing ongoing drought, which affected record numbers of people, the EU monitor added.

C3S uses billions of measurements from satellites, ships, aircraft and weather stations to aid its calculations.

Copernicus records go back to 1940, but other sources of climate data such as ice cores, tree rings and coral skeletons allow scientists to expand their conclusions using evidence from much further in the past.

Climate scientists say the period being lived through right now is likely the warmest the Earth has been for the last 100,000 years.
