I am an international relations student and I am aware of the geopolitical problems about the Artic, it geostrategic importance to countries like USA, Russia or even China.
The Artic is now one of the areas most suffering with the global warming and the presence of oil will not help to protect it from melting.
There are interests in continuing to use the Artic as a geoestrategic point, with nuclear weapons strategically placed. The importance of Artic for the world's cooldown is well known as also the impediments for the creation of a region protected from the human action. This protection would probably need a great change in human consumption but maybe is necessary.
USA and Russia still want to protect their territory from nuclear bombings, ICBM's can rapidly achieve them through the Artic, as well as Canada that as is territory at risk and China who doesn't want to be left from this game. The melting of the Artic will permit the navigation through it as well the over flying and will give it a more geopolitical interest from the actual one.
Greenland independence may alter this as they are trying reinforce their national sentimente, as well as they autonomy.
We shuldn't forget that the creation of a protect area in Artic would necessar alter the power equilibrium in that region, but that is an obligatory path for the protection of human live on Earth as we know it.
