How Are Sea Turtles Affected By Climate Change? Now, climate change is exposing sea turtles to even greater existential threats. Sea level rise and stronger storms will erode and destroy their beach habitats. Warming oceans will change ocean currents, potentially introducing sea turtles to new predators and harming the coral reefs some of them need to survive.
How are sea turtles being affected? Slaughtered for their eggs, meat, skin, and shells, sea turtles suffer from poaching and over-exploitation.
They also face habitat destruction and accidental capture—known as bycatch—in fishing gear.
How does sand temperature affect sea turtles? Because sea turtles are reptiles, they rely on the temperature of the sand in which the eggs incubate to determine the gender of the hatchling in a nest. Warmer ocean temperatures are also likely to negatively impact food resources for sea turtles, and virtually all marine species.
How does sea level rise affect turtles? increased sand temperatures, which can lead to changes in sex ratios or potentially result in mortality; increased ocean temperatures, which can lead to coral bleaching and other damage to turtle feeding habitats; changes in ocean currents, which can modify migrations paths and feeding patterns; and.

How is pollution affecting sea turtles?
Pollutants may cause immediate harm to sea turtles through direct contact or can build up in tissues over time and lead to immunosuppression resulting in disease and death.
