Study Warns of 15,000-Fold Increase in Collisions by 2100
A groundbreaking study published in Nature Climate Change reveals that global warming is driving endangered whale sharks into busy shipping lanes, increasing the risk of fatal collisions.
Key Findings:
- 15,000-fold increase in overlap between whale sharks and large ships by 2100.
- Climate change shifts whale shark habitats, leading to core losses in some areas.
- Increased co-occurrence with shipping traffic under high emission scenarios.
The Study:
- University of Southampton and Marine Biological Association researchers used whale shark satellite-tracking data and global climate models.
- Projected distribution of whale sharks under three future climate scenarios.
- Paired distribution maps with shipping traffic density information.
Expert Insights:
- “Climate change has the potential to indirectly impact highly mobile marine species,” says Dr. Freya Womersley.
- “Even complex impacts of climate change can be alleviated by our actions,” notes Professor David Sims.
Climate Mitigation Efforts:
- Reducing emissions can minimize habitat shifts and co-occurrence with shipping traffic.
- Sustainable development scenario shows potential gains in core habitat in some areas.
Consequences:
- Whale sharks, already vulnerable to ship strikes, face increased risk.
- Core habitat losses of over 50% in some national waters by 2100 under high emissions.
Call to Action:
- Factor climate change into endangered species management discussions.
- Prioritize climate mitigation efforts to protect whale sharks and other marine species.
