OK...step back here...why do you think, does all the major powers have science stations at the south pole?...well, it's not all about climate research...a lot has to do with mineral exploration...Arctic and antarctic are both said to have rich mineral deposits...Greenland is no exception btw..so, they explore techniques for deep ice mining...that is all done for future activity of course, yet it is an investment into the future.
Greenland is far more intersting than either pole...cause it never used to be a frozen wasteland...it only froze solid during the "little ice age" in medieval times, towards the end of the 15th century (that's what wiped out the vikings...the Danes living there today only came during the 18th century for whaling)...given the fact, that there is a good chance of a re-thaw of Greenland, it would make a lot of sense as long as it's..well...a bit what Alaska was to Russia...we'll see...but it sure makes sense
