The animation shows the rapid growth of Arctic ice extent during October 2025, from day 274 to day 304, yesterday.  For all of the fuss over the September minimum, little is said about Arctic ice growing 3M km2, that\u2019s 3 Wadhams in one month!.  Look on the left (Russian side) at the complete closing of the Northern Sea Route for shipping.<\/p>\n\n\n\n

The graph below shows 2025 compared to the 19-year average (2006 to 2024 inclusive), to SII (Sea Ice Index) and some notable years.<\/p>\n\n\n\n

\"Graph<\/figure>\n\n\n\n

This year October added 2.6M km2 from end of September compared to an average October increase of 3.4M km2.\u00a0 The first two weeks were above average, before the refreezing rate slowed down ending in a deficit of ~0.5M km2.\u00a0 In other terms the end of October ice extents were four days behind the average, according to MASIE.\u00a0 SII started the same, but tracked lower in the second half of October.<\/p>\n\n\n
