Welsh climate scientist mostly found buried in the pages of a good book, or wandering the footpaths of East Devon. Also on https://toot.wales/@garethsjones

Study claims models significantly underestimate observed Arctic winter warming in Atlantic sector, while at same time showing graph with the "observations" within the central 50% range of simulations. The curse of the multi-model mean strikes again. agupubs.onlinelibrary.wiley.com/doi/full/10....

Uneven Spatial Distribution of Arctic Warming in Boreal Winter and CMIP6 Historical Simulation BiasThe Arctic warming was characterized by a faster warming in the Atlantic sector than in the Pacific sector in boreal winters of 1965–2024 Coupled Model Intercomparison Project Phase 6 simulations...agupubs.onlinelibrary.wiley.com

Reminded today about time when The Sun published this story implying spray cans stop global warming (they didn't/don't). A reminder that we scientists need to be more careful about how terms like "aerosols" are understood by non-scientists (or other scientists). p.s. rest of story was nonsense!

Curious study. Claims climate models underestimate European summer temperature warming, while showing a graph where model spread appears to capture the warming fairly well. agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Accelerated European Summer Warming Driven by Atmospheric Circulation Changes in Response to Aerosol ForcingRecent acceleration of European summer warming compared to extratropical Northern Hemisphere is linked to a reduction of aerosol emissions The increase in summer temperatures and Quasi-stationary...agupubs.onlinelibrary.wiley.com

Only one tip is needed to avoid mistakes. Don't use "AI-generated" images in science. www.nature.com/articles/d41...

Three tips to avoid AI image mistakes in scienceArtificial-intelligence tools can be useful for brainstorming and creating graphics, but they can introduce errors. If you’re going to use them, here’s how to avoid problems.www.nature.com

"because more papers contain more AI-generated errors, greater human oversight is required to check the findings" www.science.org/doi/10.1126/...

AI in scientific publishing: Slower, worse, and more expensiveThere’s a saying in the management world, popularized by NASA administrator Daniel Goldin in the 1990s, that the goal of technological improvements is to make products faster, better, and cheaper. Alt...www.science.org

Fantastic memories of them filming A Very Peculiar Practice in my halls of residence at Birmingham uni, being allowed to stay in our room while Peter Davison (in pjs) filmed in the corridor - and being told to be quiet as we made too much noise - and chatting to the nuns in a stairwell!

We love you: that’s why we’re here. My celebration of 40 years of A Very Peculiar Practice - with contributions from Peter Davison, Andrew Davies, Barbara Flynn and Davids Tucker and Troughton. www.telegraph.co.uk/gift/71b8b80...

4th "Indicators of global climate change" study - discussion period has closed early. 17 May "Status: open (until 08 Jun 2026)" 2nd June "Status: final response (author comments only)" I am shocked, shocked that this has happened (again)! #EarthSystemScienceData essd.copernicus.org/preprints/es...

Indicators of Global Climate Change 2025: annual update of key indicators of the state of the climate system and human influenceAbstract. In a rapidly changing climate, evidence-based decision-making benefits from up-to-date and timely information. We track twelve key sets of indicators of the state of the climate system, clos...essd.copernicus.org

Thinking of my grandfather, Roy, who died 85 years ago during the Battle of Crete. He was a Warrant officer with the Welch regiment.

Nice to see I am not alone in refusing to use generative AI. ($) www.nature.com/articles/d41...

Went bluebell hunting on Jurassic coast yesterday. Fantastic displays above Sidmouth, East Devon.

"Hallucinated citations that make it into the academic literature can slow down and confuse other researchers’ efforts, and lead to false conclusions" (£) www.nature.com/articles/d41...

Hallucinated citations are polluting the scientific literature. What can be done?Tens of thousands of publications from 2025 might include invalid references generated by AI, a Nature analysis suggests.www.nature.com
