Two new papers at the Science and Environmental Policy Project reveal the history of the controversy over the “hockey stick” graph of global temperature over the last 1300 years. They tell a story of scientific malfeasance and outright dishonesty that have fed the fear of manmade, unparalleled warming in the late twentieth century.
The first paper linked below is by Bishop (name, not title) Hill and chronicles the hockey stick controversy. The second is by Lord Christopher Monckton and includes not only the history of the hockey stick controversy but also numerous graphs demonstrating the overwhelming evidence that the Medieval Warm Period was actually warmer than the late twentieth century. We highly recommend them both.
