I urge all policymakers to attend this vital briefing on the climate & nature crisis, which brings the latest science from leading experts straight to the people in power. I’d like to see one in every country, & the organizers are open to sharing the model. More info: www.nebriefing.org
National Emergency Briefing on climate & nature
An unfiltered assessment of the latest threats arising from the climate & nature crisis to an invite-only audience. Westminster Central Hall, 27 November. Has your MP confirmed yet?
www.nebriefing.org
A reminder for everyone to ask their MP to go to this. Politicians must know the facts on the threat & solutions. And crucially, they need to have been publicly seen to have been informed, so they can't say they didn't know.

"there is no clear evidence of an increase or decrease in either their number or intensity. Scientists are more confident that the coastal impacts of windstorms, from storm surges and high waves, will worsen as sea-levels rise."

What difference has ten years of Met Office storm names made to the UK?
Storms were first given names by the UK Met Office ten years ago to raise awareness of the dangers. Elizabeth Rizzini considers if it has worked.

Great to see @chrisgpackham.bsky.social on Laura Kuenssberg, adverting the National Emergency Climate briefing & calling out fossil-fuel funding of Reform/Tories. Why though does Laura question this as a "suggestion"?
I’ve just announced I’ll be leading a National Emergency Briefing on 27 November . At a time when climate is in free fall on the political agenda , it’s vital our leaders realise what is at stake if we do not accelerate a just , green transition for all .

61% PC/Labour/Green/LibDem, 38% Reform/Conservative. We so need to change UK voting system
Reform lost by 11% in Caerphilly - because of a surge in turnout, because Reform looked set to win the seat.
This illustrates Reform's vulnerability *because* they are leading the polls (in a 6 party system) while being an *unpopular* party. A much bigger problem under FPTP 2029 than PR 2026
