The graph above shows mid July to mid August daily ice extents for 2021 compared to 14 year averages, and some years of note.

The black line shows during this period on average Arctic ice extents decline from ~8.3M km2 down to ~5.9M km2.  The 2021 cyan MASIE line started ~400k km2 below average but as of yesterday was slightly surplus.  The Sea Ice Index in orange (SII from NOAA) started with a deficit to MASIE (in cyan) of ~300M km2.  August 14 saw the two indices mid August close together, close to average and surplus to 2007.

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 Adios, Global Warming

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