WARMING OCEAN TEMPERATURES - FOOD SCARCITY - WHALES AND DOLPHINS AT GREATEST RISK

PBS SCIENCE : MARINE MAMMALS IN U.S. WATERS : RISING TEMPERATURES : FOOD SCARCITY 

Excerpt:  Researchers with the National Oceanic and Atmospheric Administration examined more than 100 stocks of American marine mammal species and found more than 70 percent of those stocks are vulnerable to threats, such as loss of habitat and food, due to the consequences of warming waters. The impacts also include loss of dissolved oxygen and changes to ocean chemistry.

The scientists found large whales such as humpbacks and North Atlantic right whales were among the most vulnerable to climate change, and that other toothed whales and dolphins were also at high risk.
