Video alert! Our latest multimedia piece is out and we are excited to share it with you 
What is this video about?: The visualizations in this video provide a colorful and creative representation of our modelling endeavors. Additionally, the captivating images demonstrate the playful fluctuations of various components of our Earth system, including clouds, aerosols, thermal radiation, and temperature, over the course of the present and future years — specifically between 2021 and 2030.
Video creation: This illustrative work has been produced with the Earth System models used by #nextGEMS: ICON and IFS-FESOM. #ICON is a model was developed by the @MPI_Meteo and the German Climate Computing Center, while hashtag#IFS-FESOM developed by the European Centre for Medium-Range Weather Forecasts.
Don't miss out on this visual #ClimateModelling venture! Watch out video here: https://nextgems-h2020.eu/media-library/?medium_id=2016 
Day 2 of the WCRP Global KM-Scale Hackathon 2025 is off to an incredible start!
At the Hamburg node, participants have formed dynamic groups tackling topics like cloud climatology, aerosols, ice sheets, and more. Moreover, computing companies such as NVIDIA and climate modelling initiatives like DestinE Platform are also on-site, joining forces to push the boundaries of #ClimateScience. 
#nextGEMS is backing this groundbreaking global event, which brings together scientists, developers, students, and data experts from around the world to accelerate progress in kilometer-scale #EarthSystemModeling.

#IWD2024
Really outstanding work from Leeds Uni Remote sensing, led by Ben Davison, on observed changes to #Antarctic #IceShelves
This was a highlight presentation of @OceanIceEU workshop bringing #EarthObservation + #climateModelling communities together earlier this year - which I am now coincidentally writing up as a report + recommendations for publication as I travel by #crossBorderRail today...
Worth a read, Ben is really good at beautiful easy to interpret graphics.
A Saturday reminder, if you're interested in doing a #PhD in #GreenlandIceSheet melt and other #ice processes: involving #ML techniques, #ClimateModelling and on-site #glaciology, have a look at our open position announcement. Deadline 5th October!
Come and join us in #Copenhagen...

I was wondering why #BigTech companies were pushing into #WeatherPrediction and #ClimateModelling, but this assessment by a Swiss official seems plausible.
"Big Tech’s arrival on the weather forecasting scene is not purely based on scientific curiosity. [...] Our economies are becoming increasingly dependent on weather, especially with the rise of renewable energy. [...] Tech companies’ businesses are also linked to weather"

This morning is a joint workshop on the #AMOC + #ClimateModelling with @meteireann - some interesting recent work on the impact on the #SeaLevelRise alone of the dynamical component of #ocean circulation
https://link.springer.com/article/10.1007/s00382-022-06386-y
SpringerLinkGreenhouse-gas forced changes in the Atlantic meridional overturning circulation and related worldwide sea-level change - Climate DynamicsThe effect of anthropogenic climate change in the ocean is challenging to project because atmosphere-ocean general circulation models (AOGCMs) respond differently to forcing. This study focuses on changes in the Atlantic Meridional Overturning Circulation (AMOC), ocean heat content ( $$\Delta$$ Δ OHC), and the spatial pattern of ocean dynamic sea level ( $$\Delta \zeta$$ Δ ζ ). We analyse experiments following the FAFMIP protocol, in which AOGCMs are forced at the ocean surface with standardised heat, freshwater and momentum flux perturbations, typical of those produced by doubling $$\hbox {CO}_{{2}}$$ CO 2 . Using two new heat-flux-forced experiments, we find that the AMOC weakening is mainly caused by and linearly related to the North Atlantic heat flux perturbation, and further weakened by a positive coupled heat flux feedback. The quantitative relationships are model-dependent, but few models show significant AMOC change due to freshwater or momentum forcing, or to heat flux forcing outside the North Atlantic. AMOC decline causes warming at the South Atlantic-Southern Ocean interface. It does not strongly affect the global-mean vertical distribution of $$\Delta$$ Δ OHC, which is dominated by the Southern Ocean. AMOC decline strongly affects $$\Delta \zeta$$ Δ ζ in the North Atlantic, with smaller effects in the Southern Ocean and North Pacific. The ensemble-mean $$\Delta \zeta$$ Δ ζ and $$\Delta$$ Δ OHC patterns are mostly attributable to the heat added by the flux perturbation, with smaller effects from ocean heat and salinity redistribution. The ensemble spread, on the other hand, is largely due to redistribution, with pronounced disagreement among the AOGCMs.
Roughly what are the chances for an old-ish person, who got his degree in atmospheric science 20 years ago and has never worked in academia, to find a #PhD position and work on #ClimateModelling ?
Fantastic news from the #WCRP (ht @TatianaIlyina ) . If you're an #ECR interested in #Climate simulations and setting the agenda for the next CMIP, sign up here :

Interesting:
"The impact of a single shared component on pairwise RMSEs is visible for almost all the variables studied here, and the more components are shared, the stronger the reduction of RMSE is. The differences caused by the simple change of resolution or addition of secondary components are generally small, not necessarily much bigger than the impact of internal variability for future changes."

@accessrel Well, there’s a lot to say on this :-). I think everything in this diagram is in scope:
https://mastodon.nz/@bnlawrence/109511356664277128
We have some “close to best practice” and quite a lot of “lessons learned” (as in we know what not to do). Might be worth a chat in the new year.

The simulation workflow
An es-doc view of the #simulation process involved in (we hope) nearly all kinds of #modelling (or #modeling if your english is challenged 😉).
There is a design phase where projects design experiments, an activity phase & these are linked to data, software, and the scientific configuration of software. Details in the alt text! (Atomic datasets consist of 1 field/var at 1 spatio-temporal resolution for an entire simulation.)
Does this view work for you? Please share.
From François Massonnet in the other place, reporting a recent seminar in UCLouvain:
"On climate models, Prof. Thomas Stocker nails it:
« We don’t need one, but rather a hierarchy of climate models, so that we can extract just the right amount of information needed for decision making »"
(So, I’d link to this, but if twitter wont let anyone link to mastodon, I can choose not to link to twitter, so apologies Francois)
(I was over there cleaning up.)
Having looked at DCPP, I’ve been looking at other #cmip6 MIPS.
