As climate change reduces Arctic prey, migrating gray whales are stopping to forage in San Francisco Bay; surveys from 2018–2025 show a substantial share later died from vessel trauma, with many strikes occurring in the Golden Gate bottleneck. Slower ship speeds and route adjustments reduce lethal strikes, so this is both an ecological consequence of warming and a maritime policy problem.
— Shows how climate impacts cascade into human infrastructure conflicts, forcing tradeoffs for ports, shipping regulators, and conservation agencies.

Study of 114 gray whales (2018–2025) reported at least 18% of identified Bay visitors later died locally and a broader stranding analysis found over 40% of those whales died of vessel trauma; 70 dead whales were recorded and 30 showed blunt/sharp-force injuries from boat strikes.
