Are you a young academic working on climate and feel ready for a move? We are recruiting two Assistant/Associate Professors @granthamicl.bsky.social at Imperial College London @imperialcollegeldn.bsky.social (1/6)

IIRC it's something like 90% of traffic deaths in the developing world (can't immediately remember where I read that, though!)

If I was the Housing Secretary I’d probably google something like β€œis making cement energy intensive?”

It's a good opportunity for you to dramatically overcompensate. Try channeling a 1980s frat-house jock. Call them all nerds and dweebs

We can also add a much larger number of deaths caused by the vehicles' emissions and noise, both of which cause a surprising number of deaths

A reminder that humans in cars - notably omitted from this thanks to motonormativity - kill 1.2m people every year

"Generations to come"? I'm starting to suspect that the people who make money selling gas might not have a plan to transition us off fossil fuels after all!

I'm at Paddington and they've just announced the platform for my train 15 minutes before the train is due to leave. I... think this is a sign of the end times?

Yes! Which is why it matters when we shorten what's reachable

Please do it! And if you're interested in evaluating such an initiative I'd be very interested in having a chat...

I suspect you're using a North American view on this. Here we're not organised into blocks like that, and just changing direction doesn't get the same effect

Hi Ian, thoughts on expressing it in the opposite way?

A person has a 15min city available to them today under the *existing* circumstances.

Each time we remove delays we expand their personal 15min city:
1min - 14%
2min - 28%
3min - 44%
4min - 60%
5min - 78%
6min - approx doubled in size

That seems like a really nice way to approach this - good idea. Especially as you're the ones in the position to remove delays for active travellers

Net zero is the answer to Middle East energy crisis, says Business Secretary

His comments came after the conflict in the Middle East sent the European gas price up 80pc and oil prices nearly 20pc as Iranian strikes on production facilities in the Gulf spooked markets.

Alas, many lights now have sensors that cancel the wait button if the pedestrian leaves. As you can see, they'll spend extra money to avoid a motorist having even a second's unnecessary pause while refusing to make walking trips more convenient

Yes! It's so depressing seeing the massive inefficiency of Swansea's car dependency at places like that

Yes, but people have limits on how long they'll spend traveling. Hence my framing it as fewer destinations within a specific time window

'Active travel' in Liverpool City Region 'saves NHS millions' People walking, wheeling and cycling in the Liverpool City Region saves the NHS an estimated Β£53.8m a year.

Active travel saves the NHS at least Β£54 million a year just in Liverpool alone.
Other regions especially the north east need to sit up, take note and ramp up their efforts.
