Blowin' out sewage again, eh?
From skeptical science;
"It is wishful thinking to believe that the Arctic sea ice death spiral could simply be due to natural variability. The scientific literature clearly shows that human-caused warming is the main driver behind this exceptionally rapid decline."http://www.skepticalscience.com/record- ... ennia.html
"(chart in article) summer sea ice extent
Figure 1: Average July through September Arctic sea ice extent 1870-2008 from the University of Illinois (Walsh & Chapman 2001 updated to 2008) and observational data from NSIDC for 2009-2011 (blue), with a fourth order polynomial fit (black solid line). Black vertical dashed lines indicate the years 1938-43."
It also shows your 1922 lowering from previous decade, but the whole thing shows a huge drop from AGW.
