We use 30 year averages to show climatology (average weather conditions). During the 20th century the UK climatology followed a path around a confined box. With #globalwarming and #climatechange they have escaped out the box. This #dataviz shows UK rainfall and temperature.

excellent vizualization, eye-opening

Thank you for your service! You are much braver than I.

Very good.

Renewables and Batteries Comprise 93% of New U.S. Generating Capacity This Year On the California atom, Russian nuclear theft, and Taiwan’s geothermal hope

In today’s Heatmap AM:

☀️ U.S. new generating capacity will be nearly all renewables and batteries in 2026
☢️ New California bill would mostly end new nuclear ban
🏭 NRG buys New York City’s biggest power plant

freedom of speech?

Political will only shows up after the easy choices have left the room.

thanks for this

Today we’re launching Open Climate Risk, a fully open option for U.S. building-level climate risk data. It’s unique because it allows you to see not only risk scores, starting with wildfire, but also the complete underlying dataset, methods, and codebase. carbonplan.org/research/cli...

IMO a helpful discussion of climate realism via @fgenovese.bsky.social‬ in a particular context. Is the term climate realism a euphemism for "more people die sooner?" Sigh. The tradeoffs and expense only get more costly with delay.

Imagine knowing all this and still deciding to double-down on fossil fuels even when affordable alternatives are emerging.

Frightening new paper by leading planetary scientists warning of cascading risks in the #climate system 😱

I previously explored the connectedness of key earth processes in this thread below 🧵

Nope

We live in the stupidest timeline.

Each day better than the next.

On 1 February 2026, batteries in CAISO never reached zero discharge rate while the sun was down, displacing gas and imports in California and supplying renewable electricity all night long.

Canadian solar and wind project costs plummet | Pembina Institute It’s a happy coincidence of timing: we need a lot more electricity generation, and fast — and we’ve also experienced more than a decade of price reductions in renewable energy. A look at projects buil...

Canadian solar and wind project costs plummet. Renewables are now most affordable new generation, as costs are halved

This is an important point.

Empathy—in and of itself—is anti-fascist.

The arts—and the project of higher education as a whole—teach empathy, enabling you to put yourself in other people’s shoes.

So to a fascist, they must be destroyed.

Science!

If we assume long-term accelerated warming, then we'll be breaking the Paris limit of 1.5°C before the year is out.

Streak continues.

It's still winter, and more than 50% (17/33) of the days in 2026 with >100% WWS for part of the day, and 5 days straight, in CA

Gas down 58% in 2 y

Demand continues to decline

Batteries meeting demand for more hours at night

Happy Truck Day for all those who celebrate.

"...what rough beast, its hour come round at last..."

Natural variability exists, but Global Sea Surface Temperatures being already above pre-2023 records and the daily anomaly now being 0.15°C higher than in 2023 worry me a lot.

Especially with the main El Niño region still at -0.57°C...

Global warming has accelerated!

Three orthographic maps showing 2-m air temperature anomalies in December 2025, October 2025 to December 2025, and January 2025 to December 2025. Red shading is shown for warmer anomalies, and blue shading is shown for colder anomalies. Most areas are warmer than average. The mean temperature anomaly for each map is also displayed. Anomalies are calculated relative to a 1981-2010 baseline.

Temperature anomalies averaged over the last month (left), 3 months (center), and 12 months (right) across the Northern Hemisphere... December had a warm Arctic, cold continent temperature anomaly spatial pattern.

didn't take long

India’s electrotech fast-track: where China built on coal, India is building on sun | Ember Cheap electrotech is enabling India to industrialise without the long fossil detour taken by China and the West.

The energy future is emerging rapidly. USA risks falling behind, mostly because it looks to the past.
