Atmospheric Administration (NOAA) declared the whale die-off an “unusual mortality event,” a designation that triggers greater scrutiny and allocation of more resources to determine the cause. So far this year, 37 dead grey whales have turned up in California waters, three in Oregon, 25 in Washington state and five in Alaska Sea ice has been at or near record lows in the Bering and Chukchi, and water temperatures have been persistently much higher than normal, an apparent consequence of human-caused climate change, scientists say. The conditions the whales encountered last summer could be hurting the animals now as they make their annual migration north, “The sea ice has been changing very quickly over the last decade or so,” Another theory is that the number of whales has reached the limits of the environment’s natural capacity to sustain further population growth,The current estimated population of eastern North Pacific grey whales is about 27,000, the highest recorded by the agency since it began grey whale surveys in 1967, The deaths could be caused by a combination of factors, as in other die-offs,“We are seeing lots of live grey whales in unusual areas, some of them clearly emaciated, trying to feed,More dead whales are expected to wash ashore during the northward migration,
