Andrew Revkin brings a sobering message about climate change when he visits the University of Vermont tonight.
Revkin is a science reporter for the New York Times and has been delving into the global warming challenge in a recent series, with a focus on climate change skeptics and their efforts to fight regulations that would limit carbon dioxide emissions.
Revkin recently attended a conference of climate change skeptics and wrote about it in the Times.
