The north pole is the coldest place in the Northern Hemisphere. If ice at the north pole shows no signs of having melted over 50,000,000 years and it is melted now, the only reasonable conclusion which can be reached is that polar temperatures are at their warmest in 50,000,000 years.


The main point that I was disputeing was the evidence that
the ice had not melted in 50,000,000 years.

My understanding is that the hole is not actually at the north pole. It is in the artic. "The artic" is a big place. Ice not haveing melted in one place within that area
doesn't necessarily mean it didn't melt anywhere in that area.

A lot of the polar ice cap has melted, and refrozen without even melting thorough, and then melted again and so on. I don't think our techniques for studying ice core samples are so sophisticated that they can from a few samples tell whether the ice has ever melted through anyware in any part of the enormous area within the artic circle at any time within a 50 million year period.
