Critics examine the "hockey stick" graph created by Michael Mann, alleging that he cherry-picked tree ring data to create a dramatic temperature spike at the end of the record. The graph became an iconic tool for the UN Intergovernmental Panel on Climate Change (IPCC) to argue that human industry caused unprecedented warming starting in the 1880s. Skeptics claim the data was manufactured to justify political goals rather than reflect accurate historical temperature variations.
