2022 Arctic Ice Abounds at Average Daily Minimum

But alarmists still insist the poles are warming several times faster than the global average. Data says no.

Science Matters

The annual competition between ice and water in the Arctic ocean has reached the maximum for water, which typically occurs mid September.  After that, diminishing energy from the slowly setting sun allows oceanic cooling causing ice to regenerate. Those interested in the dynamics of Arctic sea ice can read numerous posts here.  This post provides a look at mid September from 2007 to yesterday as a context for understanding this year’s annual minimum.

The image above shows Arctic ice extents on day 260 (lowest annual daily extent on average) from 2007 to 2022 yesterday.  Obviously, the regions vary as locations for ice, discussed in more detail later on. The animation shows the ice deficits in years 2007, 2012, 2016 and 2020, as well as surplus years like 2010, 2014 and the last two years, 2021-2022.

Note that for climate purposes the annual minimum is measured by the September monthly average…
