To go under Thwaites Glacier, the only way is through ⬇️

This intrepid UK-Korean science team are tunnelling 1000m through one of the world's most unstable ice shelves.

They'll get daily data showing how warm ocean water is melting Thwaites from below - crucial for predicting sea level rise.

NSF Intent to Restructure Critical Weather Infrastructure

NSF just posted their Dear Colleague Letter regarding the restructuring of NCAR. www.nsf.gov/funding/info...

We organize a 1-day hybrid workshop on Convection and Turbulence in Shallow Atmospheric layers on January 29th at Sorbonne Université (Paris).
We will discuss spatial organisation of CV structures & clouds, boundary‑layer dynamics & feedback

The science budget cuts might not end up as bad as expected, but the NCAR situation is very worrying.

Qianjiadong Reservoir in southern Hunan, China, produces a double harvest: solar energy and yellow carp. The solar farm produces up to 80 megawatts of power while the fish forage beneath the panels. With a massive scale-up of solar and wind at home and cheap exports of the technology, China is driving a worldwide surge of renewable energy—Science’s 2025 Breakthrough of the Year.

Science has named the seemingly unstoppable growth of renewable energy worldwide as the 2025 Breakthrough of the Year.

A strong statement from the Director of CNRS Earth and Space about the dismantling of the National Center for Atmospheric Research: "a pillar of atmospheric and climate research is being torn down"

#NCAR is great for both research and outreach.
While digging through my archives, I found this video I made of a small homemade tornado.

This is very bad news. For our NCAR colleagues of course, for climate scientists everywhere, and really, for everyone. I had the good fortune to spend two years at the Mesa Lab as an ASP postdoc, and it was one of the best scientific environments I have known.

On a related topic, we have recently published a preprint of our own work on the bistability of ocean circulation in a box model of ice-shelf cavities: doi.org/10.22541/ess...
PhD work of Louis Saddier, with Chris Bull and Louis Couston.

Very interesting paper!

Tous ceux qui le souhaitent auront la possibilité de présenter leurs travaux. Nous encourageons en particulier les contributions des doctorants et post-doctorants. Au-delà de la coloration de cette année décrite plus haut, tous les thèmes du GDR (defi-theo-climat.ipsl.fr) sont les bienvenus.

Nous discuterons notamment des enjeux liés aux paramétrisations et à la haute résolution dans les modèles climatiques, à l'utilisation de méthodes de machine learning (émulateurs, reconstruction de champs à partir d'observations incomplètes, paramétrisations, méthodes hybrides)...

Les journées annuelles du GDR "Défis Théoriques pour les sciences du climat" auront lieu du 11 au 13 Juin à Toulouse, avec pour thème principal "Modélisation du Système Terre et Sobriété Numérique : quels avenirs ?". Plus d'informations et inscriptions: www.meteo.fr/cic/meetings...

Tackling the Accuracy-Interpretability Trade-off in a Hierarchy of Machine Learning Models for the Prediction of Extreme Heatwaves When performing predictions that use Machine Learning (ML), we are mainly interested in performance and interpretability. This generates a natural trade-off, where complex models generally have higher...

Hi Mike; recently we started looking into this for heat waves (arxiv.org/abs/2410.00984, to appear in AIES). We found some inspiration in papers like doi.org/10.1175/BAMS..., doi.org/10.1029/2022... and the group of @eabarnes.bsky.social, like doi.org/10.1029/2021...

Climate impacts of equatorial superrotation While it is expected that the large-scale tropical circulation should undergo some changes in a warmer climate, it remains an open question whether its characteristic features, such as the Hadley cell...

We have a new preprint out about the impacts a transition to equatorial superrotation would have on Earth's climate, e.g. in terms of surface temperature and water cycle. First PhD paper of Tim Marino, with @drmichaelbyrne.bsky.social arxiv.org/abs/2504.06909
