This year is “virtually certain” to be the hottest in recorded history with warming above 1.5C, EU climate monitor Copernicus said Thursday, days before nations are due to gather for crunch UN climate talks.
The European agency said the world was passing a “new milestone” of temperature records that should serve to accelerate action to cut planet-heating emissions at the UN 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.
Copernicus said 2024 would likely be more than 1.55 degrees Celsius 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, which will set the stage for a new round of crucial carbon-cutting targets, will take place in the wake of the United States election victory by Donald Trump.
Trump, a climate change denier, pulled the US out of the Paris Agreement during his first presidency — and while his successor Joe Biden took the United States back in, he has threatened to do so 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 of temperature rise heralds progressively more damaging impacts.
