Mankind and his activities are like a pimple on the Earth's arse. It may cause pain but other factors beyond his control cause greater health risks. Global warming is a natural cycle and human actions only play a small part in increasing its effect. The inverse being also true there is little that mankind can do to make any impact on this cycle to prevent warming up of Earth. That is not to say that we should not do what we can, but the scientific lie is to foster a belief that we can really prevent things like polar melting. Man is by nature a nomad who would change location with changing climate. Instead we build huge buildings on floodplains protected by earthen dams and expect nature to abide by our wishes. National but artificial borders prevent migration to more desireable areas and there are just too damn many of us in any case. If polar bears were to become extinct because of melting ice flows they would follow woolly mamoths that became extinct because of an earlier global warming.
We have changed from a species that goes with the flow of nature to one who stands in opposition, and that is the folly of fools. To believe every "Chicken Little" who cries "the sky is falling" is also the folly of fools, so I guess we are between that rock and a hard place.
