Arctic Ice Hockey Stick August 2021

.

It will be interesting to see what, if anything much, happens when solar minimum finally fades and the sunspot numbers pick up.

The graph above shows 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 ~2M km2 from ~6.8M km2 down to ~4.8M km2.  The Hockey Stick shape refers to the 2021 cyan MASIE line starting ~227k km2 below average but matching average by day 230, and in the last five days produced a surplus of 414k km2.  The Sea Ice Index in orange (SII from NOAA) started with the same deficit and also matched MASIE average day 230, but tracking the downward average since.  2019 and 2020 were well below average at this stage of the summer melt.

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
