After a sub-par March maximum, in April and now in May 2025, Arctic ice has closed the gap with the 19-year average.

During May the average year loses 1.71 M km2 of ice extent.   MASIE showed 2025 losing slightly more, 1.78 M km2, while SII showed close to average at month end.   Throughout May both MASIE and SII tracked close to the 19 year average with a dipping lower mid month.

The regional distribution of ice extents is shown in the table below.

The table shows  major deficits in the Pacific basins of Okhotsk and Bering combined are 173k km2. On the Atlantic side, Kara and Laptev combined to lose 144k km2.  The other regions are a mix of surpluses and deficits giving an overall result about 100k km2 below average or 0.8%.

Why is this important?  All the claims of global climate emergency depend on dangerously higher  temperatures, lower sea ice, and rising sea levels.  The lack of additional warming prior to 2023 El Nino is documented in a post April 2025 UAH Temps Little Changed For Now.

The lack of acceleration in sea levels along coastlines has been discussed also.  See Observed vs. Imagined Sea Levels 2023 Update
