Underreported: Algae as a Weapon of Mass Extinction

Email a Friend
Over the past decade many species of algae have expanded their range toward the poles and into areas where they previously have not been found and many speculate that global warming is to blame. New research into the fossil record is linking the toxins produced by algal blooms to numerous mass extinctions in our planet’s history. On today’s first Underreported we’ll speak to Professor Jim Castle and Professor John Rodgers, both of Clemson University, authors of a paper on mass extinctions and algae.
