Climate change is dramatically impacting reptiles worldwide by altering their habitats, shifting temperature regimes, and disrupting ecological balances. As ectothermic animals, reptiles rely on external temperatures to regulate their metabolism, making them particularly vulnerable to changes in climate. Rising temperatures can affect their reproductive success, sex determination, and survival rates, while extreme weather events and habitat loss further threaten their populations. Understanding these effects is crucial for developing effective conservation strategies to protect reptile diversity in a warming world.
