Yet even more proof of global warming

As if the Heartland Institute needed any, here we have some more proof of global warming, courtesy of the oh-so-beautiful elephant seals:

Ocean warming causes elephant seals to dive deeper

The Southern Ocean is warmed primarily in the water levels up to a depth of 1000 metres and therefore in those areas in which squid and fish ought to be found.

"This prey is moving down to greater depths presumably due to the increasing water temperatures and this is forcing the seals to follow them", explains Dr. Horst Bornemann from the Alfred Wegener Institute.
