claim: The figure traditionally cited that suggests 97 per cent of climate scientists agree that global warming is man-made was also found to be flawed.
evidence: A 2010 paper in the Proceedings of the National Academy of Sciences analysed 1,372 climate researchers and their publication and citation data to show that ( i ) 97–98% of the climate researchers most actively publishing in the field support the tenets of ACC [ anthropogenic climate change ] outlined by the Intergovernmental Panel on Climate Change, and ( ii ) the relative climate expertise and scientific prominence of the researchers unconvinced of ACC are substantially below that of the convinced researchers.
