Collapse of critical Atlantic current is no longer low-likelihood, study finds
Scientists say ‘shocking’ discovery shows rapid cuts in carbon emissions are needed to avoid catastrophic fallout
www.theguardian.com
Let me rewatch The Day After Tomorrow to see what to expect.
Hi Alex you are onto something and couplings between ice-shelves and sea ice and ocean are important areas of research. I am afraid I can't tell you anything in more detail.
To sum up, I wouldn't call this a good news story as the recent slow down of sea ice extent is only one part of a complex Arctic landscape (ice volume, ecology, temperature). I also don't think that we can draw any confident projections that the current slow down will persist in the coming years.
Network connectivity between the winter Arctic Oscillation and summer sea ice in CMIP6 models and observations
Abstract. The indirect effect of winter Arctic Oscillation (AO) events on the following summer Arctic sea ice extent suggests an inherent winter-to-summer mechanism for sea ice predictability. On the ...

7/n In my experience (e.g. Gregory et al. 2020) sea ice is too thick in climate models and there are also issues with the feedback processes in both summer and winter in the models.
tc.copernicus.org/articles/16/...
tc.copernicus.org/articles/16/...
6/n Another aspect of the study that is lacking some discussion and would be very interesting to investigate more is the so called 'model response uncertainty'. In other words how much of the model trends are due to deficiencies and biases in the models iopscience.iop.org/article/10.1...
A year-round satellite sea-ice thickness record from CryoSat-2 - Nature
Deep learning and numerical simulations of CryoSat-2 radar altimeter data are used to generate a pan-Arctic sea-ice thickness dataset for the Arctic melt period.
www.nature.com
5/n The authors briefly address this by looking at a model results on sea ice thickness but don't dive deeper into how their results hold when looking at the total sea ice volume. Satellite data on sea ice thickness exist (e.g. Landy et al. 2022). www.nature.com/articles/s41...
4/n I think the study is good and sound but might hide some more nuanced aspects of sea ice decline. Sea ice extent is a simplistic metric that encompasses a complex 3D field into a 2D projection. Other metrics, such as sea ice age for example, paint an even more alarming picture.
3/n Similar pauses or hiatuses are natural in the climate system and were extensively scrutinised in the past in the context of global climate warming (see 1998-2013 period).
en.wikipedia.org/wiki/Global_...
en.wikipedia.org/wiki/Global_...
2/n By contrasting model results and satellite observations over the 2005-2024 period this study documents clearly a 'slowdown' or 'pause' in Arctic sea ice extent (the area where sea ice fraction is above 15%).
1/n Some thoughts from me on the 'good news' story about slow down of Arctic sea ice decline that came out in the Guardian last week following a paper published in GRL

Horrendous decision to replace those lovely line judges that contribute to the spirit of #Wimbledon by a defective and inhuman robot AI system. Why don't we replace the empire and players too and commentators and ball boys and girls. Or just switch off our TV.
