Government evidence of impact of climate change:
IUCN Red List Assessment, Lepidochelys olivacea
Global warming has the potential to impact the habitats and ecosystems of Olive Ridley populations worldwide (Hays et al. 2003; Weishampal 2004) but the specific impacts are purely speculative at this time.
Most accounts have focused on the impact of global warming on incubation temperatures of eggs; which influence the sex ratio of the embryos (Hays et al. 2003).
