🌍 Berkeley Earth’s 2025 Global Temperature Report is out.
2025 was the 3rd warmest year on record. Annual global temperature reached 1.44 ± 0.09°C above the pre-industrial baseline; 770 million people experienced locally record-warm annual conditions.

2025 was the 3rd warmest year on Earth since direct observations began, and recent warming appears to be moving faster than expected.

Heat and greenhouse gas pollution rise in lock-step — until 2023, when the thermostat goes bonkers.

In a newly published paper, we find that in 2025 human emissions of greenhouse gases added around 23 billion trillion joules of heat to the world's oceans – 39 times as much as the annual energy produced by all human activity on Earth. link.springer.com/ar...

Published today: Importance of beginning industrial-era climate simulations in the eighteenth century

Defining pre-industrial to be 1750, rather than 1850, produces different (simulated) historical climate changes after 1850. Pre-1850 volcanoes & land use matter.

After a couple years of arguing whether the net effect of aerosols+water vapor was warming or cooling, it includes this banger of a model ensemble that literally does cooling then warming.

In a new article over at Carbon Brief, I explore why the past three years – 2023, 2024, and 2025 – have been exceptionally warm. The main culprits turn out to be a combination of El Nino and internal variability, declining aerosols, and a strong solar cycle: www.carbonbrief.org/...

Recently, @berkeleyearth.org expanded our temperature database by integrating the HCLIM data set.

nature.com/articles/s41...

The additional data rescued by HCLIM helps improve early reconstructions, but doesn't fundamentally change the large uncertainties due to sparse sampling.

This #GivingTuesday, we’re reflecting on a year of change and what comes next.
In 2026, Berkeley Earth will launch Synthesis, our most significant update yet—built to deliver clear, local, decision-ready climate intelligence.

New data from @berkeleyearth.org:

🎃 3rd. That is the ranking October 2025 now sits for the WARMEST October of record GLOBALLY, behind 2023 and 2024.
🌍 4% of Earth saw a record-hot October average.
🌡️94%. That's the current odds that 2025 will go down as the THIRD warmest year on record GLOBALLY

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:

The Northern Pacific Ocean is currently smashing temperature records.

And it is reaching these levels far earlier than the current generation of climate models had expected.

The open water route along through the Arctic Ocean along the Russian Coast opened in early August this year.

That puts it among the Top 5 earliest opening dates, though still weeks behind the record set in 2020.

Prior to 2005, such open water passages rarely occurred at all.
