With cold outbreaks sweeping parts of the US, some have argued that climate change is to blame. But the proposed mechanism remains quite controversial in the scientific community, and the number of extreme cold events have been decreasing almost everywhere: www.theclimatebrink....

For 50 years, global warming had a very consistent trend (+0.19 °C/decade) with a boring, predictable range of natural variations around it.
During the last three years, we've broken out above that range, suggesting the pace of change has quickened.

While the world sometimes seems metaphorically on fire right now, global warming is still progressing as well.
In 2025, global warming delivered the 3rd warmest year since measurements began. A modest step down from 2024's records, but still well above 20th century norms.

Copernicus: 2025 was 0.13°C below 2024, the warmest year on record, and only 0.01°C less than 2023, underscoring how close these years are at the top.
