Arctic sea ice grows and shrinks during the year (seasonal cycle). It reaches its annual minimum extent at the end of every summer (early-mid September). Currently, 2024's sea ice extent is already below the minimums from the 1980, 1990, and 2000 decadal averages [JAXA data]

Line graph time series showing 2025's daily Arctic sea ice extent in orange compared to decadal averages from the 1980s to the 2010s. The line showing the 2000s average is highlighted in blue to compare its annual minimum extent. There is a long-term decreasing trend in ice extent for every day of the year.

Sorry, I don't mean to sound petty, but should that be 2025 rather than 2024?

how's the volume doing? methane releasing from ESAS subsea hydrates is already happening due to the taliks being melted.

It's not looking good. Basically at or near the low.

thanks! Multi-year ice graph? It's over 90% gone.
