Can an LLM port a complex Fortran ocean model to C++/Kokkos and make it run on GPUs? Yes. We did it with FESOM2: production runs, ~3–4× speedup vs CPU, same code on LUMI, MareNostrum5 and JUPITER. Fortran as executable specification? Maybe yes :) arxiv.org/abs/2606.11356

How much do LLMs “know” about present-day climate? We asked 17 models for July 1991–2020 temperatures at 15 000+ land points — and many did surprisingly well! Preprint: arxiv.org/abs/2510.08043 🧪 #LLM #Climate

Preprint summarizing the first results from the nextGEMS project, which prepares several coupled models to run at kilometer scale: egusphere.copernicus.org/preprints/20... 🧪

This image is a global visualization of aerosol distributions on September 5, 2020, at 00:00 UTC. It represents different types of aerosols using a color-coded scheme:
• Red represents dust (du), primarily visible over arid regions like the Sahara Desert and extending into the Atlantic.
• Blue indicates sea salt (ss), prominent over the oceans, particularly in stormy regions.
• Green signifies carbonaceous aerosol (ca), which is associated with biomass burning and pollution, visible over regions like the Amazon, Central Africa, and parts of Southeast Asia.
• Yellow shows sulfuric aerosol (su), often linked to volcanic emissions and industrial activity.

The image is overlaid on a world map with latitude and longitude markers. The transparency of the colors varies to indicate concentration levels, with fully transparent areas representing minimal aerosol presence and fully opaque areas representing maximum concentrations. The right-hand legend provides a scale for interpreting the aerosol concentrations in milligrams per square meter.
