AI Insight
Gray whales have been washing up dead in unusually high numbers along the Pacific Coast of North America. Scientists have determined that the primary cause is malnutrition and starvation, linked to changes in the Arctic ecosystem where gray whales feed during summer months. Climate change is reducing sea ice and altering the availability of their prey, particularly amphipods that live on the ocean floor.
Why it matters
This die-off serves as an indicator of broader environmental changes in Arctic marine ecosystems. The decline demonstrates how climate-driven habitat changes can cascade through the food web, affecting even large migratory species and potentially signaling similar risks for other marine mammals.
