Michael Mann's [[hockey stick graph]] hid the real declining temperatures and instead showed a [[warming trend]]. Mann's graph portrayed temperatures as steadily declining since medieval times and then sharply rising in the last century and a half. Notably, his reconstruction fueled claims that 1998 and following years had the highest temperatures in 1,000 years. Once it became publicly known that man-made global warming is a hoax, as a direct result of the e-mail discussing a "trick" for adding data to each temperature series for the last 20 years, Climategate motivated the making of a video called, "Hide The Decline."<ref>Derek Erwin.
