The Arctic Ocean may lose all of its ice cover by 2040 according to The Guardian. The cause? Greenhouse gases in the atmosphere of course, topped off with images of dieing polar bears and predictions of doom and gloom. And if that is what you want to hear it is a good place to stop reading. To continue is to find shifting wind patterns pushing ice flows out into warmer waters, melting and exposing more open water in the Arctic to the warming effects of the sun.
I guess the debate is over. So much so that the real reasons for warming can be stated outright as long as we first acknowledge man-made CO2.
Sounds like how Congress operates. See what happens when you mix politics with science?
