There’s been a huge die-off of gray whales on the West Coast and scientists believe they know why. They speculate that the animals are starving to death because their food sources are vanishing in the warmer waters triggered by climate change. The National Oceanic and Atmospheric Administration is asking landowners on the coast to volunteer space to allow the mammals to decompose over time. It can take months for the 40-ton carcasses to break down but while they do, they’ll provide food for brids and other scavengers. There’ve been 30 dead or dying whales that have washed up in Washington State, 37 in California and 3 in Oregon.
