GCCI #12: Ignoring the Data That Doesn’t Fit the Narrative

Page 39 of the GCCI  Report discusses retreating Arctic sea ice.  It includes this chart:


The first thing I would observe is that the decline seems exaggerated through some scaling and smoothing gains.    The raw data, from the Cyrosphere Today site   (note different units, a square mile = about 2.6 sq. km).


But the most interesting part is what is not mentioned, even once, in this section of the report:  The Earth has two poles.  And it turns out that the south pole has actually been gaining sea ice, such that the total combined sea ice extent of the entire globe is fairly stable (click for larger version).


Now, there are folks who are willing to posit a model that allows for global warming and this kind of divergence between the poles.  But the report does not even go there.  It demonstrates an inferiority complex I see in many places of the report, refusing to even hint that reality is messy in fear that it might cloud their story.

  1. I love the wiggle room they put in about historic ice trends. They simply have no way of knowing if the recent Arctic ice is part of a normal cycle or not.
    And the models the consensus relies on are clearly back fitted.
    Please keep up the good work. Picking apart this sales brochure is important work.

  2. And specially interesting is the fact that in the first graph dramatic decline in Arctic sea ice began in 1953, but since 1953 until about 1976/77 Earth was cooling, so it’s not clear how Arctic ice could shrink in a cooling era! Mind boggling.
