Former "Climate Skeptic" Explains How His Studies in the Arctic Changed His Mind
Mark Serreze, a Research Professor of Geography and director of the National Snow and Ice Data Center at the University of Colorado tells his story of how he came to understand that greenhouse gases are behind climate change and what melting glaciers in the Arctic mean for the future of the planet.
From his piece in the "Conversation": "To be clear, we were not asking whether the impacts of rising greenhouse gas concentrations would appear first in the Arctic, as we expected. The science supporting this projection was solid. The issue was whether those impacts had yet emerged. Eventually they did – and in a big way. Sometime around 2003, I accepted the overwhelming evidence of human-induced warming, and started warning the public about what the Arctic was telling us."
