Scientist Pieter Tans of Boulder leads NOAA's Global Greenhouse Gas Reference Network, which just produced a new report that shows 2016 was another record breaking year for carbon dioxide levels rising in Earth’s atmosphere. The report landed just after Scott Pruitt, the new chief of the Environmental Protection Agency, denied the significance of carbon dioxide as a factor in global warming and climate change.

Tans spoke with Colorado Matters host Nathan Heffel about NOAA’s climate findings and the role of human activity in global warming, and what the future of this research may face in a Trump presidency.
