Extent Of Multi-Year Arctic Sea Ice Is The Highest In A Decade

NOAA claims that multi-year Arctic sea ice (MYI) is “vanishing.”

In fact, the area covered by MYI has doubled over the past decade, and is now at a ten year high. MYI is shown in white in the OSISAF ice type image below.

The extent of MYI has been rapidly increasing since 2008, and has more than doubled.

I wrote this script to generate the graph. You can run it on most Linux systems as is. I ran it on my Mac and had to install ImageMagick first.

#!/bin/tcsh
set DATE=0307
rm -f MYI_${DATE}.csv
foreach year (2008 2009 2010 2011 2012 2013 2014 2015 2016 2017)
    rm -f ice_type_nh_${year}${DATE}1200.jpg
    echo ice_type_nh_${year}${DATE}1200.jpg
    curl -O http://osisaf.met.no/quicklooks/prod/ice/${year}/03/ice_type_nh_${year}${DATE}1200.jpg
    convert ice_type_nh_${year}${DATE}1200.jpg ice_type_nh_${year}${DATE}1200.txt
    echo $year","`grep '#F' ice_type_nh_${year}${DATE}1200.txt | wc | awk -F" " '{print $1}'` >> MYI_${DATE}.csv
end

Here is an animation:


The reason for the growth is that winter wind patterns have changed, and MYI is being retained. From 1988 to 2007, winter winds were pushing MYI out of the Arctic – and now the winds are doing the exact opposite.

The NOAA claim was one of the last desperate climate lies from the Obama White House. It is time to drain the swamp.
