Scientists Suggest Climate Change as Cause of Malnourished Gray Whales

Audio

Aired 4/19/09

Tom Fudge: Grey whales are among the many animals that capture our imaginations in San Diego. Every year, they swim past our coastline twice -- once on their way to calve in the bays of Baja California, and then on their way to feed off the coast of Alaska. Now their headed back to their feeding grounds.

The grey whale was brought back from the brink of extinction, after being hunted for many years. But some marine biologists are starting to get concerned about them again. Some whales are showing signs of malnutrition, something that may be related to global warming.
