I see what you mean, Memmel, something has suddenly started to eat the arctic ice at a rate of 1 million square kilometres per day 2 days ago (as of 18:00 GMT Thursday 13th July version of the current.365.jpg).

But you exaggerate! There are 6 days of arctic sea ice left, plenty of time to call Superman...

my guess is that he already moved his fortress of solitude to the south pole.
