Weathered | Why Are So Many of Gray Whales Washing Ashore? | Season 4 | Episode 5 | PBS

From Mexico all the way up to Alaska, hundreds of gray whales have been washing up ashore. The deaths peaked in 2019, and the numbers were so significant that it led scientists to call it an Unusual Mortality Event (UME) which kicked research into gear. This episode of Weathered explores gray whales' complex food web and how what’s happening in the Arctic may just affect all of us.
