Three, melting ice is what sent Europe into their last ice age. Heat transfer in our planet happens by a series of ocean currents (eg. the Gulfstream). I cannot explain it nearly as well as in An Inconvenient Truth. You will have to see the movie to understand that idea.

This would certainly point up the need to start warming things up right away before that next ice age starts, what with all the melting and all. Good luck with reversing the trend Earth has been following for the last 18,000 years.
