I'm not sure folks have realized just how crazy the second half of 2026 and 2027 will be for global temperatures – on the back of a record-smashing El Niño event. Here is my latest estimate of where both years will end up compared to global temperatures since 1850.

your apartment, the sport of basketball, and the Republic of Korea are all social constructs. mere recognition of this fact does not actually make the question of whether you are standing in your own apartment, playing basketball, or a Korean national up in the air until settled by op ed editors

Fantastic overview of the new planning underlying the previously announced - but notional - multi-terrawatt targets for China's 🇨🇳 renewable energy capacity.

NEW – Q&A: What does China’s 15th ‘five-year plan’ for renewables mean for climate change? ✍️ Written by @anikanpatel.carbonbrief.org and Lekai Liu 💬 With comments from Yao Zhe @jamesnorman.bsky.social Pan Jiahua, Cosimo Ries and Isadora Wang Read here: buff.ly/qVU3RTg

If I can summarise @adambell.bsky.social's summary: - The kinds of problems that countries like the UK (and others) are having integrating more cheap, distributed & renewable generation into their energy systems are problems of energy affluence. You want to have them and they are eminently solvable

If I can, let me explain today's Times story. This is less to do with renewables and much more to do with where generation is located and how it shows up at a system level. /1

I feel this is a highly relevant moment to recommend one of my favourite policy anecdotes - which research that found trying to fix parental lateness for daycare pickup via charging them, inadvertently backfired - because it replaced the 'don't be an arse' with 'it costs exactly x to be an arse' ☺️

I see replies like this to Soumaya‘a column and I think, with the greatest of respect: literally all parents do this! And everyone who doesn’t have kids knows this because we have to listen to your kvetching! It’s just a question of whether codifying it helps or hurts you:

This COVID inquiry is surfacing the general problem of just how difficult it is to do precautionary governance properly - let alone work it out on the hoof, in a crisis. To state the obvious - aiming for zero waste is not only *not* the optimal strategy, it's pretty close to a sure failure state.

Counterintuitively, as the evidence submitted argued and Hallett accepts, the opposite took place. Billions were wasted in part because the PPE was more reliable than officials expected.. they over-ordered in the heat of crisis expecting that stock wouldn't turn up or be defective..

One lesson it seems like China must have learned from cleantech (and that the US seems unable to learn) is that US capital markets are extremely impatient, and if they can't make a quick buck they'll walk away and leave the tech for China to develop at scale.

Solar's sharp rise continues. As of April 2026, global solar capacity now exceeds 3 terawatt. 1 gigawatt → 1 terawatt: 20+ years 1 terawatt → 2 terawatt: 33 months 2 terawatt → 3 terawatt: 19 months

It shouldn't really need to be said, but: People in a society becoming rich enough to exit the social contract whilst living within it is a de-facto existential threat *to* the social contract - and society as a whole. Soft limitarianism is binding imo. The challenge is what to do about it.

This point needs to be made over and again: The main purpose of wealth taxes should not be to raise revenue. That's a small and secondary benefit. The main purpose should be to *reduce the fortunes of the ultrarich*. Why? Because those fortunes present a massive threat to democracy and public life.
