Why are massive numbers of sea creatures dying along the west coast right now?

Never before have we seen so much death along the west coast of North America. Massive numbers of sea stars, bluefin tuna, sardines, anchovies, herring, oysters, salmon, marine mammals and marine birds are dying, and experts are puzzled.
