Polar Bears are adaptable and the tree line will move north so there will be more ply wood for home building. With more growing seasons due to the axis tilt the ptamigans will mate more and moose will eat more and moose turd production will increase significantly!
Unfortunately the melt will effect the pingos! But not Freeper pings!
Now that I think about it, it does make sense.
The rise would be negligible. Ocean levels were lower during the ice ages because a huge ammount of water was locked up in extensive ice caps. Certainly a lot more than there is today.
However our ice caps today are much smaller and thinner than they were to begin with. There are few places that have an ice cover anywhere near what they once were. Where I live now was once covered with a mile or more of ice. Today most of our ice cover is only meters thick in most places.
