Actic Sea Ice 2021 Update

With Arctic ice having reached its September minimum, it is time for the annual update. My figures come from NSIDC https://nsidc.org/arcticseaicenews/

The last fifteen (15) years show the lowest annual arctic sea ice minima in the satellite record (ie since 1979). However,the trend over these years 2007 – 2021 is -0.26% per annum. That seems to me to be as close to flat as makes no difference. The only years, in the last 15 years, with higher sea ice minima were 2009, 2013 and 2014.

With the correct use of the english language present tense, the world IS not warming.

Figures for annual minima are:

Arctic Ice Sheet Minima

 Year  m Km2
2007 4.16
2008 4.59
2009 5.12
2010 4.62

Here is a graph of these figures alongside graphs for the previous two 14 year periods, back to 1979.
