It’s “just about sure” that 2024 would be the hottest 12 months on report, the European Union’s house programme has discovered.
The prognosis comes the week earlier than diplomats meet on the Cop29 local weather summit and a day after a majority of voters within the US, the most important historic polluter of planet-heating fuel, selected to make Donald Trump president.
Trump has described local weather change as a “hoax” and promised to roll again insurance policies to scrub up the economic system.
The report discovered 2024 is more likely to be the primary 12 months greater than 1.5C (2.7F) hotter than earlier than the Industrial Revolution, a degree of warming that has alarmed scientists.
“This marks a brand new milestone in world temperature data and will function a catalyst to boost ambition for the upcoming local weather change convention,” mentioned Dr Samantha Burgess, deputy director of the Copernicus Local weather Change Service.
The scientists discovered world temperatures for the previous 12 months had been 1.62C better than the 1850-1900 common, when humanity began to burn huge volumes of coal, oil and fuel.
Of their month-to-month local weather bulletin, they mentioned October 2024 was the second-warmest October on report, behind solely October 2023, with temperatures 1.65C better than preindustrial ranges. It was the fifteenth month up to now 16 to be increased than the 1.5C mark.
World leaders promised to cease the planet from heating 1.5C by the top of the century however are on monitor to warmth it by roughly double that.
Scientists say a single 12 months above the brink doesn’t imply they’ve missed the goal, as temperature rise is measured over a long time fairly than years, however warn that it’s going to pressure extra individuals and ecosystems to the brink of survival.
“Our civilisation by no means had to deal with a local weather as heat as the present one,” mentioned Carlo Buontempo, the director of Copernicus. “This inevitably pushes our skill to answer excessive occasions – and adapt to a hotter world – to absolutely the restrict.”
The Copernicus findings are primarily based on billions of climate measurements from satellites, ships, plane and climate stations. The temperature analyses within the ERA5 dataset on which the bulletin depends differ barely from different outstanding datasets utilized by local weather scientists within the US and Japan.

The scientists additionally discovered that Arctic sea ice had reached its fourth-lowest month-to-month degree for October, at 19% beneath common, whereas Antarctic sea ice extent hit its second-lowest for October, at 8% beneath common.
They pointed to heavier-than-normal rains that hit giant components of Europe, together with Spain, the place flash floods killed greater than 200 individuals as they ripped by way of villages and swamped houses with mud.
Final week, the World Meteorological Group (WMO) discovered the focus of planet-heating pollution clogging the environment had hit report ranges in 2023. It discovered carbon dioxide was accumulating quicker than at any time in human historical past, with concentrations having risen by greater than 10% in simply 20 years, heating the planet and making excessive climate extra violent.
“The best answer to handle the local weather challenges is a worldwide dedication on emissions,” mentioned Buontempo.
