Arctic warming affecting California coastal ecology

Via Grist, a disturbing story about the gray whales that migrate through the San Mateo County coastal area: pronounced warming means there's not enough food in the Arctic zones to support the migration, so whales are switching to different food items and staying in different areas. California may have some more resident whales, but a less dependable migration, and fewer baby whales seems likely to result in a smaller population overall. The overall result on our coastal ecology and the whale-watching economy isn't clear yet.
