^In Norway, "some ice fields are at their minimum for at least 3,000 years," said Rune Strand Oedegaard, a glacier and permafrost expert from Norway's Gjoevik University College.^

^The front edge of Jovfunna has retreated about 18 meters (60 ft) over the past year, exposing a band of artefacts probably from the Iron Age 1,500 years ago, according to radiocarbon dating. Others may be from Viking times 1,000 years ago.^

Numbers aren't really matching, there.

Melting glaciers are exposing many signs of human activity that were obviously taking place when there were no glaciers at that spot. Long before human industry. There are similar discoveries in Greenland and elsewhere. Obviously, it was at least as warm during the Medieval Warm Period than it is right now.
