I just looked for annual max sea ice in the #Arctic regions, especially Barents Sea in this case, and noticed that you don't plot annual bar charts for regions?
I wanted to check whether a change in Bjoernoeya from 2005 to 2018 , and the subsequent change 2019ff was correlating to sea ice somehow.
My plot here shows annual duration of the longest "cold wave" in dark red bars, where all daily TMin are sub zero without interruption. The golden line is the average TMin in °C of all sub zero TMIn. The blue is the annual average of all TMin. (see pic 2 for axis and legend) Pink bars are number of days with missing records – if missing days exceed 60, the year stays blank. Station records go from 1911 to January 14 2024. The year is defined as August to July.  
I noticed the change in rhythm 2005ff in the golden line, and of course in the duration of coldwaves. And again 2019, when variability returns to the golden line that was missing from 2005-2018.
