Gray whale populations along the Pacific coast have dropped nearly 30% in just four years, from roughly 20,500 individuals in 2019 down to 14,526 by 2023, and 2026 is shaping up to be one of the deadliest years on record. In this clip, marine biologist and science communicator Andrew Lewin breaks down what's driving the decline: shifting Arctic ice timing that's throwing off the whales' plankton feeding season, leaving them undernourished and more vulnerable to ship strikes and fishing gear entanglement during their 10,000 to 14,000-mile annual migration.

Andrew also covers what the advocacy group PEER is pushing NOAA to do about it, including a petition to relist gray whales under the Endangered Species Act and establish federal whale safety zones extending out to the 200-nautical-mile Exclusive Economic Zone. He compares the situation to the North Atlantic right whale, a far more endangered species that's monitored much more closely despite gray whales showing a comparably steep decline.

Takeaways:

Eastern North Pacific gray whale populations dropped from about 20,500 in 2019 to 14,526 in 2023, a decline of nearly 30% in four years.
145 gray whales have stranded (been found dead) along the Pacific in 2026 according to NOAA; PEER estimates unobserved deaths could push the real total much higher [VERIFY figure — it's an estimate, not a confirmed count].
The core driver is a mismatch between gray whale migration timing and an earlier Arctic plankton bloom caused by faster sea-ice melt, leaving whales undernourished for their return migration.
Undernourished whales are more vulnerable to fatal ship strikes and fishing gear entanglement.
PEER is petitioning NOAA to relist gray whales under the Endangered Species Act (delisted in 1994) and to establish federal whale safety zones out to the 200-nautical-mile Exclusive Economic Zone.
NOAA (via spokesperson Michael Milstein [VERIFY spelling]) says it would only declare a new Unusual Mortality Event if the cause of death were new; current strandings are attributed mainly to ship strikes, not the food-shortage root cause.
Gray whales are far less individually monitored than the North Atlantic right whale, despite a comparably steep population decline.
