The Pacific gray whale population is facing a dire crisis, with a "catastrophic mortality event" unfolding in the Pacific Ocean. This crisis is primarily driven by the climate crisis, as melting sea ice depletes their food supply, leading to starvation. However, other factors, such as ship strikes, oil spills, microplastic pollution, algal blooms, and Russian harvesting, are also contributing to the die-off. The population has nearly halved, from 20,000 in 2019 to fewer than 13,000 this year, with deaths accelerating. This alarming trend has prompted environmental groups to petition the National Oceanic and Atmospheric Administration (NOAA) to relist the gray whale under the Endangered Species Act (ESA).
Rick Steiner, an Alaska marine ecologist, emphasizes the severity of the situation, stating that the whales are in "very, very serious trouble". The stranding numbers have been significantly higher than the annual average, with 146 whale carcasses counted in the first half of the year alone. Scientific literature estimates a high ratio of unobserved mortalities offshore to observed mortalities onshore, suggesting a much larger number of deaths that are not being counted. The whales that do wash up are emaciated, indicating starvation due to the loss of food sources.
David Weller, a NOAA marine biologist, notes that the whales' resilience in the past may not be sufficient to cope with the current rapid environmental changes. The situation is particularly dire for 2026, with estimates of 2,500-8,000 whales having died so far this year, meeting the criteria for a "catastrophic mortality event".
The Trump administration's actions, including increased oil drilling and efforts to dismantle the ESA, are exacerbating the problem. Despite the clear science and the whales' immense popularity in the US West, the administration has not listed any animal as endangered or threatened. This has led to a lawsuit by Public Employees for Environmental Responsibility (PEER) if the NOAA response to the petition is ignored or rejected.
Steiner highlights the importance of action, stating that the loss of thousands of whales in two years should concern everyone. He advocates for ship speed reduction zones, which have reduced whale-ship strike deaths by about 50% in California. However, similar programs have not been implemented in Oregon, Washington, and Alaska due to shipping industry opposition.
In conclusion, the Pacific gray whale population is in a critical state, with multiple factors contributing to their decline. Urgent action is required to protect these whales and address the underlying causes of their population crisis.
