2025 on track to tie second hottest year on record: EU monitor.

The planet is on track to log its second-hottest year on record in 2025, tied with 2023 after a historic high in 2024, Europe's global warming monitor said Tuesday.

The data from the Copernicus Climate Change Service reaffirms that global temperatures are on course to exceed 1.5C °C above pre-industrial levels—the threshold considered safer in the 2015 Paris Agreement.

Temperatures rose by 1.48 °C on average between January and November, or "currently tied with 2023 to be the second-warmest year on record," according to the service's monthly update.

"The three-year average for 2023–2025 is on track to exceed 1.5C °C for the first time," Samantha Burgess, strategic lead for climate at Copernicus, said in a statement.

"These milestones are not abstract—they reflect the accelerating pace of climate change and the only way to mitigate future rising temperatures is to rapidly reduce greenhouse gas emissions," Burgess said.

UN Secretary-General Antonio Guterres warned in October that the world would not be able to contain global warming below 1.5 °C in the next few years.

Last month was the third warmest November on record at 1.54 °C above pre-industrial levels, according to Copernicus, with the average surface air temperature reaching 14.02 °C.

Such incremental rises may appear small, but scientists warn that they are already destabilizing the climate and making storms, floods, and other disasters fiercer and more frequent.

"The month was marked by many extreme weather events, including tropical cyclones in Southeast Asia, causing widespread, catastrophic flooding and loss of life," the monitor said.

Fossil fuel fight

The Philippines was ravaged by back-to-back typhoons that killed some 260 people in November, while Indonesia, Malaysia, and Thailand were hit by massive floods.

The global average temperature for the northern hemisphere autumn, from September to November, was also the third highest on record after 2023 and 2024.

"Temperatures were mostly above average across the world and especially in northern Canada, over the Arctic Ocean, and across Antarctica," the monitor said, adding that there were notable cold anomalies in northeastern Russia.

Copernicus takes its measurements using billions of satellite and weather readings, both on land and at sea, and their data extends back to 1940.

Global temperatures have been stoked ever higher by humanity's emissions of planet-heating gases, largely from fossil fuels burned on a massive scale since the industrial revolution.

Nations agreed to transition away from fossil fuels at the UN's COP28 climate summit in Dubai in 2023, but ambitions have stalled since then.

The COP30 climate conference in Belem, Brazil, concluded last month with a deal that avoided a new, explicit call to phase out oil, gas, and coal following objections from fossil fuel-producing countries.
