Million year old plant fossils were found.
The real "so what":
It shows that even without human-induced climate change with lower atmospheric C02, Greenland was completely without ice "just" a million years ago (not enough time for the position of Greenland to significantly shift).
Greenland is 100% definitely going to lose it's ice, given that it's more prone to not having ice than we thought, and unprecedented atmospheric C02. "UVM's Paul Bierman, 'it can quickly melt, pouring enough into the oceans that New York, Miami, Dhaka—pick your city—will go underwater.'"

- sradman 6y agoThe climate switched from 41 kyr glacial cycles to 100 kyr cycles about a million years ago. Greenland experienced regular interglacials during the 41 kyr cycles. None of this is surprising except that climate change obsessed scientists, journalists, and HN commenters appear to be unaware of the Marine Isotope Stages. The sediments below the western and eastern Antarctic ice sheets should show similar signs of interglacial activity timed to their own transitions to permanent glaciations.
