On this edition of Your Call’s One Planet Series, we discuss the recent spikes in ocean temperatures, which could radically affect marine species and ecosystems, hurricane activity, and weather patterns.

The National Oceanic and Atmospheric Administration recently reported that ocean surface temperatures spiked in April and May to the highest levels recorded since the 1950s.

Guests:

Dr. John Abraham, professor of thermal sciences at the University of St. Thomas, School of Engineering in St. Paul, Minnesota
