whales wither away

Scientists on the US Pacific coast are increasingly observing emaciated gray whales in what they fear is a sign that global warming is wreaking havoc in the whales’ Bering Sea summer feeding grounds.

The gray whales are migrating later, not going as far north, and are producing fewer calves, Steven Swartz, head researcher with the National Marine Fisheries Service told AFP.

Swartz, who with his team meticulously photograph and identify the migrating whales, estimates that at least ten percent of the population is seriously skinny.

Instead of looking plump coming off the summer months, they have noticeable depressions behind the head, with scapulas visible through the skin, and concave sections above the tail, he added. “This is enough to cause alarm.”
