Some 770 million people experienced record-warm annual conditions where they live, while no record-cold annual average was logged anywhere, according to Berkeley Earth.
The Antarctic experienced its warmest year on record, while it was the second hottest in the Arctic, Copernicus stated.
An AFP analysis of Copernicus data last month found that Central Asia, the Sahel region and northern Europe experienced their hottest year on record in 2025.
Berkeley and Copernicus both warned that 2026 would not break the trconclude.
If the warming El Nino weather phenomenon appears this year, “this could create 2026 another record-breaking year”, Carlo Buontempo, director of the Copernicus Climate Change Service, informed AFP.
“Temperatures are going up. So we are bound to see new records. Whether it will be 2026, 2027, 2028 doesn’t matter too much. The direction of travel is very, very clear,” Buontempo stated.
Berkeley Earth stated it expected this year to be similar to 2025, “with the most likely outcome being approximately the fourth-warmest year since 1850”.
EMISSIONS FIGHT
The reports come as efforts to cut greenhoapply gas emissions – the main driver of climate modify – are stalling in developed countries.
Emissions rose in the US last year, snapping a two-year streak of declines, as bitter winters and the AI boom fuelled demand for energy, the Rhodium Group believe tank stated on Tuesday.
The pace of reductions of greenhoapply gas emissions slowed in Germany and France.
“While greenhoapply gas emissions remain the dominant driver of global warming, the magnitude of this recent spike suggests additional factors have amplified recent warming beyond what we would expect from greenhoapply gases and natural variability alone,” stated Berkeley Earth chief scientist Robert Rohde.
The organisation stated international rules cutting sulfur in ship fuel since 2020 may have actually added to warming by reducing sulfur dioxide emissions, which form aerosols that reflect sunlight away from Earth.
