Hot Streak Persists: 2025's 3rd Warmest Nov [Data]
November 2025 marked Earth's third-warmest November on record, according to NOAA, NASA, and Copernicus—the sixth straight month ranking third without an El Niño boost. This streak signals accelerating global warming, pushing the 2023-2025 average toward the critical 1.5°C threshold above pre-industrial levels for the first time. With Arctic sea ice at second-lowest extents and regions like Europe and North America scorching, the urgency for cutting emissions and embracing sustainable solutions has never been clearer to limit irreversible climate damage.
Even without El Niño's extra heat, November 2025 saw much of the globe baking above average. Land and ocean surfaces both hit fourth-warmest marks, while Europe and North America logged second-warmest Novembers. This relentless warming underscores how human-driven climate change is stacking the odds against our planet.
The year-to-date is on pace for second- or third-hottest overall, with the three-year average from 2023-2025 likely breaching 1.5°C—a Paris Agreement red line. Experts warn this overshoot could become permanent without massive emission cuts now. Sustainable actions like rapid clean energy shifts are key to pulling back from the brink.
Arctic sea ice slumped to second-lowest November extent, fueling faster ice melt and sea-level rise. In the U.S., fall was third-warmest, with several states smashing records. La Niña may fade soon, but the long-term heat trend demands collective action to protect our future.
