Loggerhead sea turtle Faces Climate Change Threat

A 17-year study in Cabo Verde shows climate change is altering loggerhead turtle reproduction and growth patterns.

• Loggerheads are nesting earlier as ocean temperatures rise. Females now breed every four years instead of two.
• Each nest contains fewer eggs than previous decades. Adult females are gradually becoming smaller in size.
• Warmer Atlantic waters show declining marine productivity levels. Satellite chlorophyll data confirm reduced ocean food availability.
• Rising sea levels are eroding important nesting beaches. Higher nest temperatures skew hatchling sex ratios toward females.
• Climate-driven ocean circulation shifts disrupt migration routes. Smaller females produce smaller clutch sizes over ....
