Posted: 02/24/2009 - We decided to take a look at the total month end numbers for January 1980 and January 2009. In case you’ve noticed a little slight of hand we did indeed change the year to one year later. Let it show that we did this to prove that it you can use this data just about any way you want (because frankly any global changes are not very dramatic), and if we had satellites up back in the 1930’s we probably would have seen far less sea ice than what we’re looking at now. So how does today compare to 1980? January in the year 2009 showed 200,000 sq km more sea ice than 1980.
