Sad news. Bob was the godfather of land surface modeling.

I was asked by a colleague from my oil & gas days (who has remained in the industry) why UK producing its own gas is less acceptable to the Greens (& others) than importing it from America and West Africa.' The full question & my reply is now online at: climateuncensored.com/there-is-no-...

Have you read my deep-dive history of estimating global CO₂ emissions? From the first documented effort by Högbom in 1894, via Arrhenius, Popular Mechanics, Plass, Revelle, and more through to 1999: robbieandrew.github.io/www_docs/t/E...

Exeter will host the 12th International Carbon Dioxide Conference (ICDC12), 21-25 June 2027. These CO₂ conferences have been running every 4 years since 1981 ! You can register your interest at icdc12.org. Call for abstract will open later this summer. #ICDC12

Following coverage over the weekend of Sir Paul Nurse's comments that suggested that the only reason that a Fellow should be expelled from @royalsociety.org is scientific misconduct, I have written to him to explain the risks such an attitude poses of increasing sexual harassment in STEM.

I'm starting to get the emails. Reporters: please see my comments below.

I've put together my predictions for 2026 and 2027 temperatures over at The Climate Brink. I expect 2026 will likely end up similar to 2023 and 2025 at ~1.4C, while 2027 will likely be considerably warmer (conditional on El Nino): www.theclimatebrink....

The Global Carbon Project has just published the most comprehensive Global Hydrogen Budget to date. H2, although not a GHG, has an indirect Global Warming Potential 37 times more potent than CO2. Carbon Brief: www.carbonbrief.org/hydrogen-emi... Research paper: www.nature.com/articles/s41...

Direct air capture is not currently viable strategy. Likely increases carbon pollution (more carbon energy required to than saved).

Au GIEC, une bataille très politique autour des dates de publication du prochain rapport d’évaluation. Pour la 4e fois en 2 ans, les pays n’ont pas réussi à s’accorder sur son calendrier. Certains pays veulent repousser sa parution pour amoindrir l’action climatique www.lemonde.fr/planete/arti...
