The paper describing the ISIMIP3b simulation protocol and climate-related forcings from CMIP6 is now available in @egu.eu GMD. Encyclopedic reference work led by Katja Frieler and the ISIMIP core team @pik-potsdam.bsky.social. What an effort!

JUST DROPPED: For years I thought industrial electrification potential was limited.
How wrong I was.
Engineering studies point to 90%+. Long term scenarios support this.
Technology is much further ahead than we think. Question is whether policy keeps up.

In response to recent misinformation about the use of scenarios in IPCC reports: the IPCC does not conduct its own research, run models or make measurements. The IPCC’s role is to assess the available scientific, peer-reviewed literature relevant to climate change: www.ipcc.ch/2026/05/20/i...
Hard to believe I’m even writing this.
Meteorological summer hasn’t even begun, yet Paris, France has already logged more days above 32°C than its annual average.
The electricity-to-gas price ratio is the biggest barrier to electrifying European homes.
Heat pumps deliver ~3 units of heat per unit of electricity. The maths works in Sweden but not everywhere.
Much of gap is policy.

I just want to point out that temperatures over land (where we all live) have warmed over twice as fast as ocean surface temperatures. The latest update through 2025 is... not great 🥴

Burning fossil fuels has made this heatwave hotter.
True for the UK today, and everywhere else, all of the time.
