To quote from the intro at the top of the Green North Title page: "Almost all regions in the Arctic Circle (the Arctic Archipelago, northern Russia, Greenland, Iceland, etc.) are ice cap-free, along with making a new Northern Sea Route."

That covers everything in the Arctic circle, not just Greenland. They appear to have focused on Greenland, but Russia, Iceland, and other Arctic areas would be affected as well.
