The graph shows that coming out of the annual March maximum, April 2023 began 238k km2 lower than the 17 year average.  SII even showed extents ~200k km2 lower than MASIE on April 1.  However, after two weeks both indices tracked with the average until month end.  According to MASIE, the typical April loses 1100 km2, but this year lost only 918k km2.  SII shows a loss of only 590k km2 during April. Meanwhile, other years, especially 2007 were losing ice much more rapidly than average.  

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 is documented in a post Satellite Temps Hit Bottom: February 2023.

The lack of acceleration in sea levels along coastlines has been discussed also.  See USCS Warnings of Coastal Floodings

Also, a longer term perspective is informative:

The table below shows the distribution of Sea Ice across the Arctic Regions, on average, this year and 2007.

Overall, the extent is slightly below average by 68k km2, or 0.5%.  The main deficits are in Barents, Baffin and Okhotsk, partly offset by a surplus in Greenland Sea.
