As simple as possible, but not simpler: Recent article in AGU Advances co-authored by @aikovoigt.bsky.social @univie.ac.at was featured as Editor's Highlight on @eos.org making the case for the value of idealized models in Earth system science 🌏 👉

As Simple as Possible: The Importance of Idealized Climate Models - Eos

As models that simulate Earth’s climate system become increasingly complex, the use of simpler and more flexible idealized models remains important for science and education.

Paul Winkler and me talked about clouds and aerosols, which ended up in a nice short article put together by Thomas Zauner for the @univie.ac.at Environment and Climate Research Hub.

Cloud Power: How the Sky Shapes Our Climate - ECH

Almost every day, we can see clouds in the sky, but rarely we are aware of their wide-ranging impact on the climate. They can both raise and drop temperatures and have complex interactions with the pa...

Not really sure if this is the right place to advertise a postdoc position related to high resolution models and high clouds (renewable for up to 6 years!), co-supervised by @aikovoigt.bsky.social and myself, but let's try to make this place a bit more lively, at least :)

In the few days I have between jobs, I wanted to share an unvarnished perspective on what I've learned after spending three years working on supercomputing in the cloud. It's hastily written and lightly edited, but I hope others find it interesting: blog.glennklockwood.com/2025/07/less...

New paper in ERL! We study the importance of resolution for the representation of climate extremes.

We use a new generation of km-scale models to show that many important details about temperature and precipitation extremes are hidden at CMIP6-like resolutions.

Hey @copernicusecmwf.bsky.social, it seems the Copernicus Interactive Climate Atlas is down?

Is there an estimate when it will be up and running again? Asking for teaching and an outreach event on Saturday.

Thanks in advance!

We are extremely grateful to @vscluster.bsky.social to allow us to teach our students on state-of-the-art HPC infrastructure. This is so much fun, and the students and we as lecturers really enjoy it. This semester, we are running ICON climate simulations to compare to digital twins.
