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...

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).

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%).

One such cool application that I will be presenting at the #LPS25 in Vienna later this month has to do with joint inversion of sea ice and snow thickness using those two satellites together. For our paper in discussion on this check egusphere.copernicus.org/preprints/20...
