Promoting papers feels a bit strange this week considering everything going on, but I am excited about our new paper showing a larger influence of Gulf Stream anomalies on the atmospheric circulation over Europe in models that resolve weather fronts (1/6)
doi.org/10.1029/2023MS004123
Our paper and its implications for ongoing high-resolution modeling efforts is nicely summarized in an Editor's Highlight by Hannah Chistensen. (5/6)

These simulations were only possible by a university researcher like me with a lot of technical help (and computer time) from @NCAR_Science , especially from co-authors Adam Herrington & Isla Simpson. This project has been a slow cooker we've been working on since late 2020 (6/6)

Using AI to understand the Earth System response:
The Forced Component Estimation Statistical Method Intercomparison Project (ForceSMIP) uses statistical and machine learning methods to try to figure out the true forced response, as reflected in the evolving pattern of surface temperature anomalies.

To optimize climate models, how do we prioritize between resolution & ensemble size, between physical param. development & incorporating AI? In a perspective paper out this week, Tapio Schneider, Ruby Leung, and myself argue we need a balanced approach: acp.copernicus.org/articles/…
Included is (1) an evaluation of how climate skill has improved over the last 20 years and is continuing to (mostly) improve with efforts to increase resolution, (2) considerations for successful process-informed parameterizations, ... (2/3)
Is the La-Niña-like warming pattern over the past 40+ years forced or unforced?
In this seminar, I argue it is forced & show statistical + hi-res model forced response estimates. Peter Huybers discusses obs. uncertainty & evidence models have too little low-freq. variability
Recording and chat transcript of April's ECS-Cloud Feedback symposium are now available:

Really fun "debate" between Peter Huybers and @ClimateAnomaly on "Can we rule out internal variability as the main driver of recent tropical SST trends?"

"#Climate models have done well, but they also show some biases. It is essential to improve them in order to understand the impact of #GlobalChange on regional weather", explains @ClimateAnomaly (@usys_ethzh). Statistical and machine learning methods offer one solution 🌎 #SGCD24

Join us next month for a panel discussion on
"Can we rule out internal variability as the main driver of recent tropical SST trends?"

After last month's clear-sky session, this month featured great talks by Catherine Stauffer and Brett McKim on cloud feedbacks

New paper in @PNASNews led with @cristiproist shows that a weird spatial pattern of temperature change has slowed global-mean warming since 1980. Because the pattern could evolve in the future, observed warming doesn’t help us constrain long-term warming.

Meet our Speaker Robert Jnglin Wills @ClimateAnomaly @usys_ethzh at the #SGCD24 and discuss what leads some climate change impacts to be robust and others uncertain.

ALT The Swiss Global Change Day is the annual event organised by ProClim where well-known experts present challenges and highlights of climate and global change research covering a broad range of topics. It is also an opportunity to present research results by posters and to discuss them with colleagues. The most attractive and comprehensive posters submitted by students or postdocs will be honoured with a travel award of 1000 francs. Poster can be submitted in the following categories: - Geosphere | Biosphere - Atmosphere | Hydrosphere - Human Dimensions | Sustainability The following experts are going to give a talk: - Valentina Bosetti (Bocconi University) - Sabine Fuss (MCC Berlin) - Robert Jnglin Wills (ETH Zurich) - Géraldine Pflieger (University of Geneva) - Nicolas Senn (University of Lausanne) - Thomas Stocker (University of Bern) - Diana Ürge-Vorsatz (Central European University) (confirmed, subject to change)

Really excited to share our new paper on climate-invariant machine learning science.org/doi/10.1126/scia… to solve extrapolation issues under climate change, led by the great Tom Beucler
Less than a week to submit an abstract for #EGU24. If you work on understanding the contributions of internal variability and forced responses to historical or future climate change and climate impacts (e.g., using large ensembles), then please consider submitting to our session!
Join us at #EGU24 for a session on “Disentangling internal variability and forced response: Changes, Methods, Mechanisms and Impacts” with Andrew Schurer (U. Edinburgh) as an invited speaker! Abstract Deadline January 10th. Submit here: meetingorganizer.copernicus.…

Observations from 1980–2020 of near-surface atmospheric water vapor in arid and semi-arid regions don’t match climate models. This gap between expectations and data has major implications for hydroclimate projections, including fire hazards. In PNAS: ow.ly/JFLG50QmrbP
