Maine Voices: World was warmer in the past without terrible effects

What would you think if someone told you that in Greenland, about 9,100 years of the last 10,500 years were warmer than now? Or that the coldest years during this time span were in the late 19th century, at the close of the "Little Ice Age"?

Further, what would you think of the fact that there is nothing unusual about the mild, cyclic warming of our planet over the past century, comparable to the Roman Warm Period or the Medieval Warm Period? The latter enabled the Viking settlement of Greenland, which was later abandoned due to the return of severe cold during that same Little Ice Age.
