Minneapolis Star Tribune: Anthropologist quoted on ancient global warming trend

An article in the Minneapolis Star Tribune's On Weather blog about the unseasonable warm temperatures Minnesota is experiencing reports the NOAA just released a summary of summer conditions in the Arctic region and that the warming that occurred 4,000 to 6,000 years ago was substantial, but according to UB anthropologist Ezra Zubrow, "This was a slower change, about one-third the rate we face today….It took a thousand years for the earth to warm as much as it has over the past 300 years – roughly the time spanned since the beginning of the Industrial Revolution."
