Scientists question the use of “tipping point” metaphor in climate change discussions

KITTA MacPHERSON / RUTGERS TODAY – A group of scientists, including researchers from Rutgers University-New Brunswick, Princeton University and Carleton University, has questioned the accuracy and utility of the metaphor “tipping point” in calling attention to the threat of climate change.

The phrase, while perhaps initially useful as a clarion call that warns about sudden, drastic changes, may now be confusing the public and impeding action, researchers said.

Writing a perspective in Nature Climate Change, the scientists, from the Rutgers Climate and Energy Institute, Princeton’s Center for Policy Research on Energy and the Environment, and Climate Resilient Societies through Equitable Transformations (ReSET) Lab at Carleton University as well as six other academic institutions, argue that the notion of tipping points, when referencing physical and human aspects of Earth’s changing climate, is not well-defined and often applied inappropriately.
