The ice caps are melting. whether or not it has to do with human activity, or if we can do anything to change this remains to be seen. The Northwest passage as been open before in human history, that's why the peoples of Alaska, Greenland, Norway and the upper parts of Siberia all register as one "race" in DNA studies and through language. They didn't walk hundreds of miles across frozen waste land, they paddled, sail or drifted about. We find human artifacts in valleys that we thought had always been under ice. The world has been warmer, and it's been colder to. The important thing to keep in mind is that fossil fuels are a finite resource, very dirty to extract and refine, and use. Also, if we can stop lining the pockets of the twisted principalities and mind controlling Kalifs of the oil producing nations, maybe we can finally see them develop more ration forms of government that will end all this hatred they have for the West (us).
