Fulham fan looking for an escape from the toxic place.

One of the first "outrageous" claims I saw as Jason Arday's media hounding unfolded was that he ran 30 marathons in 35 days! Wow! What a thing to claim! And the newspapers all suggested there was no evidence he actually did it. Well, they clearly didn't look very hard 🙄 🧵 1/26

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.

Our world is a tinderbox as we approach 1.5C above preindustrial temps. We’re locked in for at least 2C, & on track for 4C in our children’s ‘lifetimes’. Tumbleweeds as we wait for governments, the media & the public to provide a proportionate response to this information.

Neoliberalism in a nutshell. UEFA on FIFA's proposal: “The moment external investors acquire ownership interests ... football changes forever. Commercial return becomes a permanent obligation. ... Every decision is no longer driven by what best serves the game, but by what best serves shareholders.”

the four stages: 1. Allister Heath's columns are not real 2. Allister Heath's columns are not serious 3. OK, they are real and serious but it's too late to do anything about them 4. Our only hope is to find a way of adapting to Allister Heath's columns

Welcome to the frontpage of the Daily Telegraph* website... * The newspaper that has relentlessly spent the past three decades seeking to belittle climate science and undermine climate action at every turn

Yesterday the Telegraph reported on my comments about air conditioning. The comment section is quite something. I have apparently become a hero of the anti net zero crowd by saying something what I think is sensible about air con. Allow me to point out three ironies in this 🧵

Air conditioning has become the latest front in the energy culture war. Depending on who you ask, it is either wasteful excess we must resist or the only sensible response and anyone urging caution is a zealot. A few thoughts in this 🧵

FACTCHECK: A guide to manufacturing headlines, by the Times 1) highlight upfront costs of an “eco” home (EV, heat pump, solar) 2) pretend that petrol cars and gas boilers are free (yes really) 3) count upfront “eco” costs twice, for good measure 4) that’s it!

It's probably time European journalists wrapped their heads around Heat Index (temp + relative humidity). In high humidity, sweating is less efficient, making heat worse, e.g.: Experiencing 35°C in London UK (70% RH) is more dangerous than 50°C in Phoenix Arizona (15% RH)

It will be record hot today because of climate change. It will keep getting hotter until the world reaches net zero emissions. These are the facts of the case and they are undisputed.

Heat pumps are the most efficient heating technology ever invented. They harvest and compress pre existing heat in the air, ground or water and transport it where it is needed. That energy is all around us. And it does not have to pass through the Strait of Hormuz.

Wouldn't it be cool to invest trillions of dollars into a technology that would actually make society better? Maybe we can call it “HI” — Human Intelligence. Instead of “data centers”, we could fund “schools”. Instead of *stealing* art, literature, and science, we help people *create* it. Crazy!

🍺 Cheers! This Guinness brewery was designed from the ground up as a carbon-neutral facility using heat pumps coupled with renewables. They just got planning permission to double its brand new fossil-free brewery in Kildare.

Greek Proverb: "A society grows great when old men plant trees whose shade they know they shall never sit in". That's not what we are doing now. We are pillaging the planet, each other, and the future, for a quick buck. We need to do better.

We need to talk a bit about how utterly absurd the March heatwave was in the USA. This heatwave would have been impossible without a boost from climate change, but even with climate change it remains a deeply unlikely event. A thread looking at some of the numbers. 🧵

Times: "Tony Blair urges Ed Miliband: Don’t be ideological on net zero" "Britain should produce more clean energy while accelerating domestic oil & gas production" - TBI This would be a tad more credible if the Tony Blair Institute's clients weren't despotic petro-states like UAE & Saudi Arabia.

Every sensible government will spend the coming months accelerating the deployment of solar, batteries, heat pumps, and EVs, especially for lower income households. It’ll be a hell of a lot cheaper in the long run than subsidising fossil fuels the next time prices spike, which they will.
