Modeled reconstruction of July #Arctic sea ice volume since the year 1901 - comparison between PIOMAS-20C and PIOMAS data sets now updated through 2025... Data information available at doi.org/10.1175/JCLI...

Line graph time series for Arctic sea ice volume in every July from 1901 through 2025. Two datasets are compared between PIOMAS-20C (a blue line) and PIOMAS v2.1 (a dashed red line). There is large interannual variability, but a long-term decreasing trend since 1990.

Non-scientist here. Can you help me understand news stories in the last year or so that mention increases in Antarctic sea ice?

I am sorry, but I don't know what you are referring to. Antarctic sea ice is currently the 2nd lowest on record: zacklabe.com/antarctic-se...

If it increased from last year being the lowest, there is the rhetorical trick that gives you your answer.
