RISING temperatures could mean no male loggerhead turtles hatch at a key breeding ground by the end of this century, new research suggests. The University of Exeter study also warns that by 2100, more than 90% of loggerhead nests on the Cape Verde islands could incubate at “lethally high temperatures”, killing turtles before they hatch. The sex of turtle hatchlings is determined by incubation temperature, and this study combined current temperature and hatchling data with projections from the Intergovernmental Panel on Climate Change (IPCC).
