For the National Parks Serviceshe keeps an count of the whales that migrate up from Hawaii to feed in Glacier Bay and Icy Strait every summer.“Young whales, calves went missing.

With Happy Whale, Cheeseman set out to do a simple population count. “But when we first saw these numbers, it turned a population study into a climate study,” Cheeseman sai
