Interesting article. Unrelated (to ice) thought: how many people buy a $200 atlas? I admit I am kind of a sucker for flipping through books like this, but a super accurate, up to date atlas is soon out of date. The ice sheet discussed in the article will continue getting smaller, and geopolitical boarders will keep changing (some could be different by publication). A 50 year old atlas or encyclopedia is fun to look at to see how much has changed/stayed the same. A five year old copy doesn't hold the same charm.
