The sentinel species case
A marine ecologist tracking climate signals would argue —The numbers tell a story we can't look away from: Eastern North Pacific gray whales have crashed from 27,000 in 2016 to 12,500 in 2025, with calf counts so low this population isn't rebounding the way it has from past declines. These animals are arriving in San Francisco Bay visibly emaciated because their Arctic feeding grounds — the amphipod beds they've depended on for millennia — are collapsing under warming seas. When a 40-tonne animal abandons a migration route it has followed for generations and shows up starving 2,000 miles south, that's not a quirk of animal behavior. That's the ocean telling us something is profoundly wrong beneath the surface, and whales are simply the part we can see.
