Pacific coast grey whales are getting smaller—and scientists say climate change is the culprit. A groundbreaking study reveals these majestic marine mammals have shrunk by 13% in length since 2000, sparking concerns about their survival in our warming world.
Using drone images of 130 whales, researchers from the University of St Andrews and Oregon State University found a 2020-born grey whale will likely be 1.65 meters shorter as an adult compared to one born two decades ago. That’s like an average American woman dropping from 162cm to 142cm in height—imagine the ripple effects! 🐋💔
The decline is linked to disrupted ocean cycles and food scarcity. Fewer nutrients from 'upwelling' events mean less prey for whales, forcing them to work harder for meals. \"Smaller whales face higher risks—they’re less resilient,\" explains the study in Global Change Biology.
This discovery isn’t just about whale sizes—it’s a wake-up call for marine ecosystems. As human activities and climate shifts reshape oceans, scientists warn: the future of marine life hangs in the balance. 🌊🔬
