I've created a new dashboard for The Climate Brink that is updated daily with ERA5 global mean surface temperature data. It includes daily anomalies, monthly and annual forecasts, and a bunch of interactive data visualizations: dashboard.theclimatebrink.co…

Degrowth is dumb.
We can have an abundant and equitable future by (largely) replacing digging fossil fuels out of the ground and burning them with clean energy technologies like solar, wind, geothermal, nuclear, etc.

The world has warmed by around 1.4C since 1850.
It took 148 years for the first half of that warming to occur, and just 27 years for the second half!

Neat piece in today's Washington Post highlighting my projections for global temperatures in 2026 and 2027 in light of the potentially record setting El Niño event developing later this year: washingtonpost.com/weather/2…

James Hansen and colleagues have a new piece out today arguing that 2026 is actually on track to be the hottest year. He may be right; there is a real chance of a record even in my model, but I'd personally bet against it: jimehansen.substack.com/p/ye…

But the nice thing about making near-term predictions is that you don't have to wait long to be proven wrong.
Either way we are in for a wild ride this year and next between an expected record El Niño and record global temperatures.

Our 2026 Indicators of Global Climate Change paper is out! We find that the human-induced warming was 1.37C in 2025, and the current rate of warming is 0.27C per decade, on track to firmly pass 1.5C in about four years.

Second, an update to Gavin Schmidt and my WMO State of the Climate 2024 analysis on drivers of record warmth in 2023 and 2024 (and now 2025):

One advantage of having future predictions on my Climate Dashboard is that I can look back at how well they have performed compared to actual observations. For example, here are all the past ENSO predictions vs actual ENSO3.4 temps: dashboard.theclimatebrink.co…

And here are the daily global temperature values compared to all the daily ECMWF EC46 forecasts since I added them to the dashboard a month ago:
