Welcome to the bleak new world where AI assesses grant proposals. I think we should push back on this - certainly until they can prove it works www.resultsense.com/news/2026-09...

AI triage rejects half the bids in a UKRI-funded grant call
Academics are dismayed after an EPSRC-funded cybersecurity network used AI models to sift 179 grant bids, sending only the top half on to human review.

In an article on UK energy prices rises, BBC quotes someone urging gov to back Jackdaw and Rosebank, and doesn't say that won't help prices at all. To me, that is failing to do what journalists should do www.bbc.co.uk/news/article... please complain.

Thanks @yorkshireeveningpost.co.uk for discussion of El Nino. The Pacific may feel far away, but our world is interconnected in so many ways & they affect us. Floods, droughts, heat, food & water availability get worse until we have phased out fossil fuels. www.yorkshirepost.co.uk/news/weather...

Great work engaging people in Ilkley. Most people underestimate how concerned others are. Most MPs underestimate how much people support action on climate. Time for a @nebriefing.bsky.social . Time to write to your MP if they are not already supporting it.

Everyone agree this is simply a lie? When did media stop holding MPs to account? 1. High gas prices are not a result of Labour approach to N Sea. Set internationally. No amount of gas from UK waters could make a signicant difference. Taxes etc are a small fraction, and cant explain increases 2.

Good work from @eciu.net on the double-whammy that is possibly UK lowest harvest on record followed by record El Nino. UK media so far I think more focused on El Nino impacts on UK storms - I guess the food price story will grow as impacts appear. eciu.net/media/press-... eciu.net/media/press-...
