The editorial goes on to review the scientific evidence and call for action. Knute Nadelhoffer is a professor of ecology and evolutionary biology and the director of the U-M Biological Station. Donald Scavia is director of the U-M Graham Sustainability Institute, the Graham Family Professor of Environmental Sustainability, and a professor of natural resources and environment and civil and environmental engineering.
“It's time to move on from old debates about whether human-caused climate change is occurring and start making decisions that minimize future climate change,” they conclude.
