Vulnerability of Marine Turtles to Climate Change


Marine turtles are generally viewed as vulnerable to climate change because of the role that temperature plays in the sex determination of embryos, their long
life history, long age-to-maturity and their highly migratory nature. Impacts of different consequences of climate change, such as temperature and sea level rise, extreme weather events etc. in combination with anthropogenic pressures are discussed in this book chapter.

Conservation recommendations to increase the capacity of marine turtle populations to adapt to climate change include increasing population resilience, for
example by the use of turtle exclusion devices in fisheries, protection of nesting beaches from the viewpoints of both conservation and coastal management, and
increased international conservation efforts to protect turtles in regions where there is high unregulated or illegal fisheries (including turtle harvesting). Increasing
research efforts on the critical knowledge gaps of processes influencing population numbers, such as identifying ocean foraging hotspots or the processes
that underlie the initiation of nesting migrations and selection of breeding areas, will inform adaptive management in a changing climate.
