By\u00a0Ron Clutz<\/a><\/p>\n\n\n\n

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

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

During May the average year loses 1.71 M km2 of ice extent.\u00a0 \u00a0MASIE showed 2025 losing slightly more, 1.78 M km2, while SII showed close to average at month end.\u00a0 \u00a0Throughout May both MASIE and SII tracked close to the 19-year average with a dipping lower mid-month.<\/p>\n\n\n\n

The regional distribution of ice extents is shown in the table below.<\/p>\n\n\n\n

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.\u00a0 The other regions are a mix of surpluses and deficits giving an overall result about 100k km2 below average or 0.8%.<\/p>\n\n\n\n

Why is this important?\u00a0 All the claims of global climate emergency depend on dangerously higher temperatures, lower sea ice, and rising sea levels.\u00a0 The lack of additional warming prior to 2023 El Nino is documented in a post\u00a0April 2025 UAH Temps Little Changed For Now.<\/strong><\/a><\/p>\n\n\n\n

The lack of acceleration in sea levels along coastlines has been discussed also.  See Observed vs. Imagined Sea Levels 2023 Update<\/a><\/strong><\/p>\n\n\n\n

Also, a longer-term perspective is informative:<\/p>\n\n\n
