Arctic Ice Persists Mid July 2024

The animation shows Arctic ice extents on Day 197 for years 2007 to 2024. The regions vary in the amounts of ice cover Mid July, larger overall in recent years and with more Eurasian ice.

The graph below shows June daily ice extents for 2024 compared to 18 year averages, and some years of note.

The black line shows on average Arctic ice extents decline from a maximum of 10.8M km2 on day 167 down to 8.3M Km2 by day 197.  2024  tracked near the 18-year average in June, then was in surplus during July before ending slightly above average.  SII was somewhat higher than MASIE most of June and July until sliding into deficit mid July.  2007 was somewhat below average throughout, while 2020 ice started and ended much in deficit.

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 UAH June 2024: Oceans Lead Cool Down.

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

Also, a longer term perspective is informative:

post-glacial_sea_levelThe table below shows the distribution of Sea Ice on day 197 across the Arctic Regions, on average, this year and 2007. At this point in the year, Bering and Okhotsk seas are open water and thus dropped from the table.

The overall surplus to average is 80k km2, (1%).  The only major deficits are in Laptev, and secondly in Hudson Bay, going to open water soon anyway.  That is more than offset by surpluses elsewhere, especially in Chukchi, Kara and Baffin Bay.  Note that 2007 had 375k m2 less ice extent at July 15.
