🌍🌫️ What happens to climate model results when we update historical aerosol data for CMIP7?
Read the #research article co-authored by Stephanie Fiedler, EXPECT researcher from @uniheidelberg.bsky.social, on SP forcing data for #CMIP7 and its first application in the model ICON XPP: bit.ly/4qUOl5x
building on the #CORDEX-CMIP6 framework while expanding to incorporate new model components and scientific priorities. Happy for having the possibility to play in the future a role in shaping the #CORDEX contribution to #CMIP7, 2/3
🌏 Behind every COP summit is a massive global climate modeling effort that compares Earth system models around the world: #CMIP7. Read this article by @andyhogg.bsky.social and Tilo Ziehn about how Australia is participating to help predict our planet's future.

We are excited to share this important overview of #CMIP7! Australia is submitting one model configuration, ACCESS-ESM1.6, for the FastTrack component of CMIP7, and mobilising a large-scale initiative of researchers from many disciplines and institutions.

Next week our ECR group are starting a #MachineLearning sprint to speed up development of our ice sheet smb emulators. (Part of our #CMIP7 prep)
I'm looking for hints, ideas, tips and inspiration to smoothe and accelerate the process.

this should be common knowledge, i.m.h.o.
I really want to know about adaptations to digital earth system models for the upcoming #CMIP7 comparison!

The UK National Climate Science Partnership has launched it's first newsletter and is organising a webinar (8th May) for the UK climate modelling community to discuss plans for delivery of results from UK models to CMIP7. Links to details via: terrafirma.ac.uk/uk-national-... #CMIP7
A graph showing relative humidity declines over the continents developing a robust negative trend since the 2000s. In 2024 till January 2025 we had again highly negative values near record levels. The drying of continents supports exceptional high temperatures, flash droughts, higher rates of wind and water erosion (floods hitting parched out landscapes), or that dryness is the main metric for large wildfires to become possible. In other words models underestimating the drying trend of the continents do not see the collapse of the terrestrial carbon sink coming that involves lots of other knock on effects. https://climate.copernicus.eu/january-2025-warmest-january-and-lowest-arctic-sea-ice-extent-month?utm_source=socialmedia&utm_medium=bs&utm_campaign=january-2025-warmest-january-and-lowest-arctic-sea-ice-extent-month
Just for the record: this model error is massive!

Ada Gjermundsen (UIO), Jean Rabault (MET NO) and I are looking for a PhD candidate to work on climate reversibility, working with NorESM - helping with the #CMIP7 effort and developing new hybrid ML climate emulation tools. www.jobbnorge.no/en/available...

"This is urgently required for updating impact assessments of extreme weather on ecosystems and climate services, but also for ensuring that climate and Earth system models are fit for purpose in predicting the magnitude and frequency of extremes."Computational power the problem #CMIP5 #CIMP6 #CMIP7
We are hiring a researcher in land model calibration at @ciceroclimate.bsky.social in Oslo, Norway - developing FATES-CLM for NorESM in #CMIP7 with @rosieafisher.bsky.social . Land surface modelers and UQ/ML people, we'd love to hear from you. www.finn.no/391168589
What I wonder here is by which mechanisms can the SOx-cloud forcing be delayed by 3.5 years after cloud reductions from the IMO regulation occurred. Especially, the regional cloud effects happen in the first few months as SOx is fast removed from the lower troposphere. #CMIP5 #CMIP6 #CMIP7
Shows the sea ice decline in the different scenarios "Observationally-constrained projections of an ice-free Arctic even under a low emission scenario"; https://www.nature.com/articles/s41467-023-38511-8
Slowly model results are closing in on an Arctic sea ice free September:
"The stronger SIA declines have advanced first ice-free years to around the 2030s–50s in all SSP scenarios."
Sadly, the spread is way too large as it could happen as early as 2027-2030...

If they are correct this is the most important study that was published in 2024:
Vertical mixing is already suppressed by stratification
This could then shift ocean heat uptake to shallower depths causing SSTs to accelerate...

This is also another one of the most important findings - messages of 2024:
"The first ice-free day in the Arctic Ocean could occur before 2030"
So many knock on effects this would mean including another acceleration of global warming in a time we truly do not need that
#climate #CMIP7 #politics
Just for the record:
"Our findings suggest that two not well understood problems of the current generation of climate models are connected and we highlight the need to increase understanding of decadal-scale variability."
#CMIP5 #CMIP6 #CMIP7 #climate #uöäü1models #IPCC
Another reason why we are currently flying blind - models have real issues to simulate ocean heat uptake:

Very important:
The permafrost regions will continue to thaw for decades after emission stop - not possible to quantify the contribution to the warming in the pipeline as too many wildcards exist...

The recent temperature jump is driven also by the Antarctic which is now joining the heating...
Its another indication that circulation changes - disturbances of the flow patterns - are now also driving the recent acceleration of global warming
#climate #Antarctic #CMIP7
I'm also a fan of these models that's the reason I am a hardcore critique :D #CMIP7
My opinion: Humanity needs one model that gets improved so simulate Earth, not ~140 wrong ones forced to produce the same outcomes :D
From an emergent non-linear system perspective just a mega fail...

And here another study - this time as early as 2030: "Observationally-constrained projections of an ice-free Arctic even under a low emission scenario"; www.nature.com/articles/s41...
Important the more recent the studies the more earlier the first ice free year is projected... #CMIP7
"One approach to constraining, or narrowing the range of, answers across climate models is the use of emergent constraints." dept.atmos.ucla.edu/alexhall/eme... its kind of a short cut #CMIP7
📣 CMIP7 Description Paper now available for comment on GMD 📣
Including climate science questions #CMIP7 will help to address, including model characterisation, process understanding, impacts and adaptations analysis, climate assessments; and more!
Comment now 👉 zurl.co/cmip7-paper
New approaches in Earth system models now enable estimation of emissions pathways/budgets for prescribed warming levels: esd.copernicus.org/articles/15/.... Next step: extend this to climate impact drivers and socio-economic impacts. It seems #CMIP7 largely continues to rely on traditional methods🤔
What's changed? In short - #CMIP7 is a step towards a more operational model, a slimline fast-track set of critical science and policy-relevant experiments targeted at climate assessments, with scope for more rapid updates and infrastructure to support community-led science.
