Good to see C4 cover this. Interesting language, "technically a possibility" - I sometimes think the enormity of this risk leads subconsciously to that kind of language. www.channel4.com/news/atlanti...
Atlantic current collapse could trigger ‘unprecedented’ cooling, scientists warn

I'd say for weather (ie short term) yes. Probabilities are well founded and well evaluated. In some comments you might still have more storyline, but underpinned by probabilities. Climate is different

The Somerset Levels used to be under the sea, and with 2m of sea-level rise possible within 75 years, and several more metres rise thereafter, resettlement is the only long-term solution

NEW ANALYSIS: UK household electricity bills have risen over the last 5 years.
BUT: Despite frequent claims that net zero is to blame: 2/3 of the increase is because of high gas prices shows new @ukerc.bsky.social report.
Arguably without renewable energy the UK would see even higher bills today.

Compared with most UK journalism, it's refreshing to see a reporter stating straight up these are climate crisis stories. It shouldn't be. But you really don't see much UK media treating UK floods like that

This is a super insightful graph from @kingsmillbond.bsky.social illustrating how countries like India that are experiencing economic development later are skipping over some (not all) fossil dependency.

I've long thought that our climate crisis response must urgently learn from this. The experts were shouting it's not safe, but the management didn't want to hear that message. They wanted to carry on. Climate scientists often say it will be "catastrophic" without rapidly phasing out fossil fuels...
When the engineers say, "It's not safe. Something bad will happen," it's always best to listen and err on the side of caution.

Forty years ago, the Challenger space shuttle disintegrated just after lift-off. A small team of engineers tried to prevent the tragedy.
