How climate stressors can serve as early warning signs for North Carolina and beyond

Researchers at the City University of New York's Advanced Science Research Center have published new findings that could create a new way to detect climate threats before they show up. They call it a "Climate BioStress Sentinel System" that would track how climate change is stressing living things, using those signals in a preventative fashion. WRAL climate change reporter Liz McLaughlin explains how this works and how it could be implemented in a state like North Carolina.
