To me this was a highlight of the @nebriefing.bsky.social
A vital perspective from an "establishment source", traditionally listened to by the right-wing, from a sector that knows how to handle risks, threats and emergencies.
Well worth a listen.

But potentially 100 000 under evacuation orders in USA & it's still barely registering. We have normalised the climate crisis so quickly (BBC don't mention climate)

Though @financialtimes.com do add "even a temporary “overshoot” of the 1.5C level .... would impact food, water & nature, & displace populations, with long-lasting consequences even if temperatures later drop"

Tragic. I don't know how much is defendable at Hemsby, but we need a serious, public & open conversation in UK about what we do when people's homes become uninsurable & undefendable.
“What do I do now for a home? I'm homeless.”
Hemsby is collapsing to the climate crisis and government inaction. Yet the people who did the least to cause this are paying the price. We're taking legal action to force Starmer to step up:
