Yes. "When climate warms or cools, the changes are generally much more drastic at high latitudes than they are closer to equator. Temperatures measured in ice core bore holes in Greenland show, for instance, that central Greenland temperatures during the Last Glacial Maximum were about 20 degrees lower than today while the tropics were only a couple of degrees cooler."
