PARIS: The last two years exceeded on average a critical warming limit for the first time as global temperatures soar “beyond what modern humans have ever experienced,” an EU agency said Friday.
This does not mean the internationally-agreed 1.5°C warming threshold has been permanently breached, but the Copernicus Climate Change Service said it was drawing dangerously near.
The EU monitor confirmed that 2024 was the hottest year on record, surpassing 2023 and extending a streak of extraordinary heat that fueled climate extremes on all continents.
Another record-breaking year is not anticipated in 2025, as climate skeptic Donald Trump takes office, and a deadline looms for nations to commit to deeper cuts to rising levels of greenhouse gases.
But the UK weather service predicts 2025 will still rank among the top three warmest years in the history books.
This excess heat supercharges extreme weather, and 2024 saw countries from Spain to Kenya, the United States and Nepal hit by disasters that cost more than $300 billion by some estimates.
Los Angeles is battling deadly wildfires that have destroyed thousands of buildings and forced tens of thousands to flee their homes. US President Joe Biden said the fires were the most “devastating” to hit California and were proof that “climate change is real.”
Copernicus said sustained, unprecedented warming made average temperatures over 2023 and 2024 more than 1.5°Celsius hotter than pre-industrial times.
Nearly 200 nations agreed in Paris in 2015 that meeting 1.5°C offered the best chance of preventing the most catastrophic repercussions of climate change.
But the world is nowhere on track to meeting that target.
“We are now teetering on the edge of passing the 1.5°C level,” said Copernicus climate deputy director Samantha Burgess.
Copernicus records go back to 1940 but other sources of climate data, such as ice cores and tree rings, allow scientists to say the Earth today is likely the warmest it has been in tens of thousands of years.
The 1.5°C threshold is measured in decades, not individual years, but Copernicus said reaching this limit even briefly illustrated the unprecedented changes being brought about by humanity.
Scientists say every fraction of a degree above 1.5°C is consequential, and that beyond a certain point the climate could shift in ways that are difficult to anticipate.
At present levels, human-driven climate change is already making droughts, storms, floods and heatwaves more frequent and intense.
The oceans, a crucial climate regulator which absorb 90 percent of excess heat from greenhouse gases, warmed to record levels in 2024, straining coral reefs and marine life and stirring violent weather.
Warmer seas mean higher evaporation and greater moisture in the atmosphere, causing heavier rainfall, feeding energy into cyclones and bringing sometimes unbearable humidity.
Water vapor in the atmosphere hit fresh highs in 2024 and combined with elevated temperatures caused floods, heatwaves and “misery for millions of people,” Burgess said.
Johan Rockstrom of the Potsdam Institute for Climate Impact Research said hitting 1.5°C was a “stark warning sign.”
“We have now experienced the first taste of a 1.5°C world, which has cost people and the global economy unprecedented suffering and economic costs,” he said.
Scientists say the onset of a warming El Nino phenomenon in 2023 contributed to the record heat that followed.
But El Nino ended in early 2024, and scientists have puzzled over why global temperatures have remained at record or near-record levels ever since.
In December, the World Meteorological Organization said if an opposite La Nina event took over in coming months it would be too “weak and short-lived” to have much of a cooling effect.
“The future is in our hands – swift and decisive action can still alter the trajectory of our future climate,” said Copernicus climate director Carlo Buontempo.
Nations agreed to transition away from fossil fuels at a UN summit in 2023 but the latest meeting in November struggled to make any progress around how to make deeper reductions to heat-trapping emissions.

UK veterans are ‘ticking time bomb’ after Iraq war chemical exposure
- Fifteen former RAF personnel were deployed to the Qarmat Ali water plant in 2003, which was contaminated with sodium dichromate
- Veterans say they were not screened or protected, and are now living with serious health conditions
LONDON: Fifteen British servicemen who worked on a carcinogen-contaminated water treatment site during the Iraq war say they were not offered biological screening despite official guidance saying they should have been.
The former Royal Air Force members, who have suffered from ailments including cancer, tumors and nosebleeds, told Sky News they were offered no medical assistance or subsequent treatment after having been exposed to toxic sodium dichromate at the Qarmat Ali water treatment plant in 2003.
The channel said it had seen a letter from the RAF’s medical authority stating that senior officers knew of the dangers posed by the substance.
Peter Lewis, 53, was one of 88 personnel deployed to guard the site, which was deemed vital for getting Iraq’s oil industry up and running. He told Sky: “I’ve had eight or nine operations to remove cancer.
“I’ve had so many lumps taken out of my neck, one on my face. This is something I’m literally fighting every year now. It’s constant.”
Qarmat Ali, the former troops say, was covered in ripped bags of bright orange sodium dichromate.
“We were never warned what the bags of chemicals were,” Jon Caunt, another former serviceman, said. “We were breathing this stuff in.”
His former comrade Tony Watters added: “I never thought about what it was. We were told the site is safe.”
Several months after deployment to the site, however, the servicemen were joined by two workers wearing protective gear who placed signs around it reading: “Warning. Chemical hazard. Full protective equipment and chemical respirator required. Sodium dichromate exposure.”
Watters said: “When you left the site, your uniform was contaminated, your webbing was contaminated.
“You went in your sleeping bag, and that was contaminated. And you were contaminating other people with it back at camp.”
Andy Tosh, who has led the group of veterans as they sought answers from the Ministry of Defence, said: “Even with the warning signs going up … they kept us there. They knowingly kept us exposed.”
The RAF gave some of the men a leaflet on their return to the UK, warning of the dangers of the substance, but not all were told.
The letter seen by Sky acknowledging the dangers posed to the veterans made a “strong” link to “increased risk of lung and nose cancer” as well as numerous other issues. It suggested personnel sent to Qarmat Ali should have their medical records altered to mention their exposure to sodium dichromate.
“Offer biological screening. This cannot be detailed until the numbers exposed are confirmed,” the letter also said.
An inquiry into US personnel deployed to Qarmat Ali found that 830 people were “unintentionally exposed” to sodium dichromate, giving them access to support from the US Department of Veterans Affairs. This came after the death of Lt. Col. James Gentry from cancer in 2009, which the US Army determined came “in line of duty for exposure to sodium dichromate.”
There has been no such inquiry by UK authorities despite British personnel being deployed at the site for longer than their American counterparts.
Thirteen of them have suffered from cancer and similar symptoms, including one who developed a brain tumor.
Jim Garth told Sky: “My skin cancer will never go away … It’s treatable, but when the treatment is finished, it comes back, so I’ve got that for life really.”
Lewis added: “I’m actually getting to the point now where I don’t care anymore … sooner or later, it’s going to do me.”
Caunt described his former colleagues’ conditions as a “ticking time bomb.”
He added: “We do not know what’s going to happen in the future."
The MoD insists medical screening was offered to personnel at the time, despite the men stating that it was not. In 2024, several met with Labour MPs about the issue. One, John Healey, who is now the UK defence secretary, said at the time the veterans should have “answers to their important questions.”
In a statement, the MoD said: “We take very seriously the concerns raised by veterans who were deployed to guard the Qarmat Ali Water Treatment Plant in 2003.
“As soon as we were alerted to the possible exposure of Sodium Dichromate, an environmental survey was conducted to evaluate typical exposure at Qarmat Ali. Results showed that the levels at the time were significantly below UK government guidance levels.”
A 2004 letter seen by Sky News suggested, however, that the MoD knew the levels of sodium dichromate were higher.
“Anyone who requires medical treatment can receive it through the Defence Medical Services and other appropriate services,” the MoD said.
“Veterans who believe they have suffered ill health due to service can apply for no-fault compensation under the War Pensions Scheme.”
Watters called on the government to hold an investigation into what happened at Qarmat Ali.
“We are the working class, we are ex-soldiers who have put our lives on the line and you’re turning a blind eye to us,” he said.
Garth added: “We felt let down at Qarmat Ali all those years ago, and we still feel let down now.”
