At least 97% of climate scientists who are actively publishing climate research in peer-reviewed journals believe that human greenhouse gas emissions are a significant contributing factor to climate change. Only 1% of climate scientists believe that humans are playing no role in climate change, or that climate change is not occurring at all (Anderegg, et al., 2010; Doran and Zimmerman, 2009). Associate Professor Chris de Freitas, climate lecturer at The University of Auckland, is part of that 1%.
