Roughly 20 years ago, climate scientist Michael Mann published his famous “hockey stick” graph that he says “galvanized climate action” by showing unprecedented global warming. Mann used the 20-year anniversary of the graph to opine on the “industry-funded” attacks “to discredit the iconic symbol of the human impact on our climate,” which Mann claimed had withstood criticism. The hockey stick, in contrast, is the result of a field of research called paleoclimatology (the study of past climates) that, while fascinating, only provides one thread of evidence among many The name evokes scenes of hockey players skating on ice, but the so-called “hockey stick graph” is really about the human impact on global warming. USC Dornsife climate scientist Julien Emile Professor Michael Mann — the litigious climatologist who invented the discredited “Hockey Stick” chart and was implicated heavily in the Climategate scandal — has lost a long-running lawsuit against Canadian climate sceptic Dr Tim Ball. He sued Ball for defamation in the British Columbia courts. British Colombia: After six years, the libel lawsuit filed by Michael Mann, the climate scientist who created the ‘hockey stick’ climate model and graph, is finally coming to an end. The lawsuit was against Tim Ball, a retired professor at the University of Winnipeg, for saying that the data used by Mann was fraudulent and that he should be in the state pen instead of Penn State.

The "hockey stick" describes a reconstruction of past temperature over the past 1000 to 2000 years using tree-rings, ice cores, coral and other records that act as proxies for temperature . The reconstruction found that global temperature gradually cooled over the last 1000 years with a sharp upturn in the 20th Century.
