Simply scrapping over who will extract the most profit out of our dying Arctic is the wrong response. We are at the point where Global Warming should not be viewed as a fountain of profit opportunities but something to first and foremost be avoided and combated. The wrong profit opportunities arising from Global Warming can provide an incentive to make it worse. Case in point, the oil and gas industry can open up new wells in the Arctic by worsening Global Warming.
The melting poles is not simply a matter of when coastal inhabitants have to find a new lease further inland on higher ground. It goes way beyond that. The presence of Polar ice factors intimately into many aspects of our World that make it capable of supporting life.
Again, we all seem to be resigned to sea levels rising but, again, after that we need to realize that a lot of ice is needed on the surface of the planet in order to anchor our World in a zone of habitability.
