Investigating Climate Change: The Hockey Stick Curve
In 2009, a group of hackers leaked emails from the University of East Anglia, and climate scientist Michael Mann found himself at the center of a conspiracy scandal. The stolen emails were used to accuse him of fabricating evidence for climate change. However, the accusations were later disproven, and investigations cleared Michael and his colleagues of any wrongdoing. Michael's work on the hockey stick curve, a graph depicting average global temperatures over time, became a target for critics in the fossil fuel industry. Despite the attacks, subsequent research has confirmed the climate change trends highlighted by the hockey stick curve, showing unprecedented changes due to human activity.
