Berkeley Earth

Berkeley Earth is releasing an early access edition of our new high-resolution temperature dataset. This dataset promises unprecedented regional & local resolution for understanding past climate changes, with a 0.25° x 0.25° spatial resolution. berkeleyearth.org/introducing-th… 🧵

The current heatwave in the US Southwest is utterly destroying many records for this time of year. Phoenix, Arizona has ~90 years of daily temperature data, and yet recent temperatures beat the previous March record by 5 °F (2.8 °C), and would actually tie the record for April.

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.

The current year is expected to conclude as the 3rd warmest in the instrumental record (94% chance), behind 2023 and 2024 and slightly above the long-term trend. Further, it is unlikely that 2025 will exceed the 1.5 °C threshold. 11/

Temperature Update for October 2025 Third warmest October in the instrumental record. Similar conditions to September. A weak La Niña returns in the Pacific. 2025 is very likely to be the 3rd warmest year. 🧵

September 2025 was the third warmest on record in the Berkeley Earth dataset. But this downplays how anomalous it was; without 2023 and 2024 this year would have been well above any prior records and well above the long-term trend:
