• As the Atlantic warms, many fish along the east coast of North America have moved northward to keep within their preferred temperature range. • Black sea bass, for instance, have shifted hundreds of miles up the coast.
Article Summaries:
- A new study finds that marine species along east-west coastlines face a higher risk of extinction than those on north-south shores. Researchers attribute this disparity to climate‑driven range shifts: as Atlantic temperatures rise, many fish on the U.S. east coast are moving northward to stay within their preferred thermal limits. The black sea bass, for example, has migrated hundreds of miles up the coast. The findings suggest that species confined to narrower latitudinal gradients may be more vulnerable to warming, potentially accelerating local extinctions if suitable habitats become scarce.
