Gray whales are dying again off the Pacific Coast. Scientists look at if climate change is to blame

Dozens of gray whales are dying in Pacific Ocean waters again this year and human-caused climate change may be to blame, scientists say.

At least 70 whales have died since the start of the year along Mexico’s Baja California peninsula, marine scientist Dr. Steven Swartz told The Los Angeles Times this week. Swartz’s Gray Whale Research in Mexico — an international team of researchers who study the whales in Laguna San Ignacio — have been observing the gentle giants since the 1970s.
