"Bicycling has done more to emancipate women than anything else." — Susan B. Anthony, 1896. Yet today, women only make up 40% of riders. This International Women’s Day, let’s push for ambitious and inclusive cycling policies that make our cities more equitable places for women and girls. #IWD

30 years as both a driver and a cyclist, and the biggest lesson I’ve learned is this: Drivers do not have to overtake cyclists. You can just wait behind them until it’s safe to pass.

Is anyone else slightly unnerved (and impressed) by the way Chat GPT talks to itself when solving a problem ? Very human “inner thoughts” vibe

"Rachel Reeves obtained 5m swimming badge aged 4. We tracked down the swimming teacher who said Rachel's foot touched the floor"

Brilliant list, thanks for communicating it so clearly. Another huge thing is the circular economy. I love using examples like a council run swimming pool in Devon being heated by a data center (not AI). This reduces costs and emissions for both and everyone wins. These heat networks will only grow.

“Even for an intermediate emissions scenario [which is our current emissions pathway] the probability of AMOC shutdown is way above 50%” (AMOC shut-down means Europe and parts of South-East Asia become uninhabitable, by the way.) 1/4

A good day to listen to our proud, joyous history of the BBC: One of the greatest British inventions of the 20th Century. An institution which, even at its worst, is far better than its detractors podcasts.apple.com/gb/podcast/t...

Awesome 🧵...

I don't fully agree with this analysis. It's more nuanced than the article makes out. Offsets are often held to a higher standard than other form of decarbonisation. For example: "projects with leakage, such as protecting part of a forest but effectively pushing loggers elsewhere" 1/x

It's yelling into the void but something tell me it just needs to kept being said: if you are still posting, RTing, or lurking on X, you are helping keep users there and you are helping this guy pull in advertising revenue. You are a volunteer worker for a slobbering, drug-addled white supremacist

WATCH & SHARE: This is very good. A prominent youtuber is actually giddy (but also very thorough in covering the joys, advantages, issues and challenges) about how trying biking for transportation in London has changed his life. Easy to watch & more convincing probably than 99% of public campaigns.

Wonderful graphics! Now also add in the extraction fuel and shipping fuel used in mining and transport of fossil fuels... the numbers look even worse for legacy fuels ;)

Interesting analogy "Dr J Gergis, one of the lead authors on the latest IPCC report, prefers to represent climate change as a cancer –a disease that takes hold and grows and metastasises until the day when it is no longer curable and becomes terminal.You could also think of that as a tipping point"

"Build as much clean energy as possible as fast as possible" should be our No. 1 national priority in the coming decade. All our national resources should be bent to the task. The president should talk about it every week in a national address. It should be the moon shot X100.

NEW: Car bonnets are becoming a half-centimetre higher every year, driving road safety fears. This #carspreading trend where supersized SUVs crowd out space in towns and cities is also leading to cars that are more dangerous in a crash. 🧵

I would suggest it's now clear we should be doubling down on the electrification of buses ⚡️⚡️⚡️

I think a lot about what Carl Sagan said in one of his final interviews.

Read that last bit again. "Tipping cascades" -- which would effectively augur the end of a recognizably human world -- are a real possibility on our *current trajectory*. We are toying with the fate of all future generations of human beings. Look around. Are we acting like it?

"Tipping points" are "thresholds where a small additional change in global warming will cause [major biophysical systems] to irreversibly shift into a new state." *Cascading* tipping points occur when crossing one threshold triggers another, & so on. We should be extremely scared of these. So...

Well, this is strong reponse to US tarrifs. "The most ambitious housing plan since the Second World War"

@davidallengreen.bsky.social "Reeves also implicitly confirming that external consultancy spend will increase by about the ‘saved’ amount." How do you work that out from the article?

Please can we change GHG reporting from TC02e to "Portion of large donner equivalent" ?

It's been a long time since Private Eye's satire has made me audibly wince, but this is so to the point if it were a knife people would demand it be banned.

Ok, I think I've finally got all the settings & Apps as I need for the Xbox accounts for my 3 boys. Insanely complicated

Maybe we should get our greenhouse gas emissions as close to zero as possible? 🤔

Scientists think there's a decent chance that, if global temps rise 2 degrees above pre-industrial levels, it could trigger a cascade of tipping points that further accelerate warming, up to 5 or 6 degrees. AKA: "A cluster of abrupt shifts occur in ESMs [Earth system models] at 1.5 to 2ºC."

Delivering training to planning professionals yesterday on places for walking, and it was the first time many of them had talked just about *walking*. 70% of under-1km journeys, 25% of all journeys, part of almost all public transport journeys. First time.

Quantified economic impacts from climate change are quite uncertain. I mean it will be bad, but no one knows for sure how bad. So it's better thought of as an non-linear increasing risk of full societal collapse and massive species loss. Which I don't think CBAs are well suited to modelling?

Auschwitz was at the end of a long process. It did not start from gas chambers. This hatred was gradually developed by humans. From ideas, words, stereotypes & prejudice through legal exclusion, dehumanization & escalating violence... to systematic and industrial murder. Auschwitz took time.
