Enig i at man ved sproglig argumentation / refleksion har stor værdi af selve processen.
Matematik adskiller sig dog, qua formalisering. Jeg tænker dog hans tanker stadig er relevante. Og ja, jeg er matematiker og ex-forsker.

Matematikeren Terence Tao skriver virkelig indsigtsfuldt om de muligheder og udfordringer som AI giver for vidensproduktion/validering/anvendelse. Kan virkelig anbefale at følge ham, hvis du/I ikke allerede gør.

Der er snart valg i Sverige. Svensk klimapolitik kan også indirekte påvirke dansk klimapolitik, fx mht brændstofafgifter og flypassagerafgifter.
Er der nogle svenskere her på kanalen som kan opsummere hvad partierne mener om sådanne afgifter, særligt de partier som forventes at kunne danne regering?

Hvad er vigtigst - biodiesel eller busruter? Det sidste.
Hvis valget står mellem at bevare busruter eller at fastholde mål om brug af biodiesel, så er det bedre at droppe biodieselen end busruterne.
Både fordi klimagevinsten fra biodiesel er tvivlsom og fordi busserne uanset snart kører på el. Og så er det bedre socialt, økonomisk og klimamæssigt at bevare et mobilitetstilbud der giver et alternativ til at skulle have (endnu en) bil.

Når det er mere sandsynligt at noget bliver forsinket end kommer hurtigere, så skal der ‘overbookes’.
Men fordi man politisk ikke har gjort det hidtil konkluderer mine kolleger nu at
1) der er pt under 1% chance for at nå 2030-klimamålet, og
2) hvis vi skal have 50 % chance for at nå 2030-målet, så skal der findes yderligere reduktioner frem mod 2030 på i alt 3,3 mio. ton CO2e.
På 4 år. På med arbejdstøjet.

As Bill McKibben writes on Bluesky: “If you told me I could have a great review of my new book from the NYT or from Cory Doctorow, I'd take the latter in a heartbeat”

Jo flere der bor i tætte byer, des lavere aftryk klimaeffektivt (især hvis man fokuserer på at bruge det som allerede er bygget).
Men det skal også være rart at bo i byen - alle kan jo ikke 'flygte' til et kolonihavehus/sommerhus.
Derfor er bynatur er ikke bare pynt. Hvis man (kommuner) griber det rigtigt an, bidrager det - ud over det visuelle - også til biodiversitet og klimatilpasning.
Det har mine kolleger lavet en ny rapport om.

US National Weather Service is considering posting on Bluesky: https://www.weather.gov/media/notification/pdf_2025/pns25-50_comment_Bluesky_at_NWS_HQ.pdf
Maybe somebody (with a bit more US scientist clout - @npub1ke2…meew ? ) should suggest they also post to Mastodon?

Same here.
And @npub1fdr…lvhs is crystal clear on what the issue is: “Any system where users can leave without pain is a system whose owners have high switching costs and whose users have none.”
I always wondered what the business model of Bluesky was to be. It cannot be ‘to churn VC money into code and users’ indefinitely, so what will it be?

The tax discount for hybrids has been counter-productive - here's the conclusion from German data:
"I find that
- PHEV subsidies were used by consumers to purchase larger & heavier vehicles
- PHEV users seldom charge their vehicle
- the elimination of subsidies for PHEV would have led to a yearly reduction of 167,139 tons CO2" 😤 #dktrp #dkgreen #dkpol https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4530036
