"The European Union's Copernicus Climate Change Service (C3S) reported data up to November 2025 that show this year has been 1.48 degrees C above the average from 1850 to 1900. That's right around the target set by the 2015 Paris climate agreement, under which countries pledged to limit warming to below 1.5 degrees C and well below 2 degrees C. Despite 2024's record-setting temperatures and 2025's proximity to the 1.5-degrees-C threshold, scientists must take into account many years of data before they can say with certainty that the Paris Agreement's target has been breached."
"Still, trends are heading that way. The three-year average for 20232025 is on track to exceed 1.5C for the first time, Samantha Burgess, C3S's strategic lead for climate, said in a statement. These milestones are not abstractthey reflect the accelerating pace of climate change and the only way to mitigate future rising temperatures is to rapidly reduce greenhouse gas emissions."
"Record heat has become far more likely than record cold. Each of the world's 10 hottest years have occurred within the last decade. The new temperature report comes just weeks after this year's United Nations meeting to uphold the Paris Agreement ended with countries avoiding mention of fossil fuels, disappointing climate scientists and advocates who had hoped for stronger pledges to bring down planet-warming emissions."
The Copernicus Climate Change Service data through November 2025 show global temperatures about 1.48°C above the 1850–1900 average, close to the 1.5°C threshold. 2024 was the first year to exceed 1.5°C, and the 2023–2025 three-year average is on track to surpass that threshold. The trend indicates accelerating climate change and a growing likelihood of record heat, with the ten hottest years occurring in the last decade. Rapid reductions in greenhouse gas emissions are necessary to mitigate further warming. A recent United Nations meeting concluded without explicit fossil-fuel mentions, frustrating many climate advocates.
