Well, actually, exploration and mining in Greenland has a long history, but it is accelerating for many reasons, including a more suitable climate.

And Greenland wants to break from Denmark - another political element to the Neo-Arctic drama. From the WP story:

With a territory larger than Mexico and a population that could fit inside a football stadium, Greenland badly needs new sources of income to provide jobs and combat chronic social ills. Its economy leans heavily on one major export — shrimp — and is propped up by an annual block grant of more than $500 million from Denmark.The question is what to do about it. Many in Greenland, including Prime Minister Kim Kielsen, view resource development as the nation’s best chance for self-sufficiency. The issue is tightly intertwined with Greenland’s fervent movement to win independence from Denmark, which began colonizing the sprawling territory almost 300 years ago. Greenland negotiated the right to self-rule in 1979 and has since built the institutions of a modern democratic society.

Here's the overview from the govenrment website:

(Disclosure: I used to work with a company that had a relationship with London Mining. I did not work on the Iron Project but was familiar with it.)

Your long-term speculations about a BiPolar future are interesting, though, and food for thought. Thanks.
