New Scientist: Males don't stand a chance in a warmer world, if they happen to be painted turtles. A temperature rise of around 1 °C is all it would take for the species to become 100 per cent female and earmarked for extinction. Painted turtles (Chrysemys picta), found in lakes and streams across North America, are one of many reptile species whose sex is determined by temperature. Eggs in warm nests are likely to hatch as females, while males hatch in cooler nests, although no one is sure why. In recent...

Climate change severe threat to marine turtles
2013-02-19 08:25:00| Climate Ark Climate Change & Global Warming Newsfeed
Times of India: Scientists have sounded the alarm over the mounting threat to marine turtle populations worldwide from climate change and coastal development. The scientists have made a strong pitch for protecting key nesting grounds, and areas that may be suitable for the purpose in the future, to ensure that the marine reptiles have a better chance of withstanding climate change. Turtles play a significant role in seed dispersal and ecology. They act as scavengers of the marine ecosystem, cleaning up a lot...

Australia: Climate change limits turtle's nests

ScienceAlert: A global map predicting where sea turtle nesting sites occur throughout the world has been developed by a James Cook University researcher, to help define where they lay their eggs and to help better protect their habitats. Dr David Pike, from JCUs School of Marine and Tropical Biology, said the project was an attempt to map sea turtle nesting habitat in coastal areas across the world. The three-year study, "Climate influences the global distribution of sea turtle nesting", was the first step...
