Over that past century, the pH of the ocean has decreased from 8.2 to 8.1. This doesn’t seem like a lot, but it represents a faster rate than at any time in the last...

Ocean Acidification with Dr. Francisco Chavez

Dr. Francisco Chavez of the Monterey Bay Aquarium Research Institute estimates that a million tons of CO 2 enter the ocean hourly. His studies in Peru explore the phenomenon of ocean acidification, which occurs...
