Information About Sea Turtles: Threats from Climate Change

Problem: Sea turtles use both marine and terrestrial habitats throughout their lifecycle, so the effects of climate change can have devastating effects on these endangered species. Sea level rise affects the beach run by the turtle. The turtle's memory is "marked" on the beach's magnetic map where it hatches. This gives them the ability to return to the same place in decades and repeat their ancient nesting ritual. These beaches began to disappear as the polar ice caps melted and the sea level rose. Direct impacts of sea level rise include loss of beaches, ecologically productive wetlands, barrier islands and so on.

The rise in the temperature of the nesting beach will also affect the tortoise. Because the turtle is a reptile, it depends on the temperature of the egg egg to determine the sex of the hatch in the nest. Normally, the nest is cold and cold, some of the eggs become men, the upper part becomes warm, some eggs of the nest become women. As the temperature of the nest rises, scientists predict that women are more likely to cause genetic diversity than males larvae. As seawater temperature rises, food resources of sea turtles and almost all marine life may be adversely affected. Coral reefs are an important food source for sea turtles and are at great risk. Almost half of the US coral reef ecosystems are in poverty or equity. As the temperature rises, coral reefs are experiencing "bleaching" effect, which causes some coral reefs to die.

Solution: There are many discussions about actions that may affect climate change and temperature, but people can change climate change with a simple step.

Case study: In the Caribbean, 50% of the corals have been lost primarily due to the rise in seawater temperature since 2005. Between 1997 and 1998, large bleaching estimates caused serious deaths in 16% of the world's coral reefs. Strong signs of recovery were observed in several places, but many places take decades to fully recover. Regarding the sex ratio of turtles, the beach of Playa Grande on the Pacific coast of Costa Rica produced 70% to 90% of the women's nest by age. On the Pacific coast's Junquillal beach is usually too hot, eggs do not hatch at all. And the scientists began to bring the eggs to the nursery - basically began digging holes in the cooler part of the beach. When young turtles emerge, the rangers take them from the nest to the water and protect them from human and animal predators.

Climate change can also pose a threat to sea turtles. Since the temperature of the sand at the nesting beach determines the sex of the turtle in egg development, it is feared that the temperature rise may produce too many females. However, further research is needed to understand how climate change affects the sex distribution and other threats of sea turtles. The injured turtle was rescued and released to the sea if possible by a specialist institution such as Gumbo Limbo Nature Center in Boca Raton, Florida, Karen Beasley Sea Turtle's Life Recovery and Recovery Center in North Surf City.

WWF will investigate how sea turtles are affected by climate change and help to identify the best way to alleviate the sea turtle's vulnerability to changes in environmental conditions. We work with the communities all over the world to monitor and protect nesting beaches and help turtles adapt to the effects of future climate change. In the East Pacific and the Caribbean, we promise to raise awareness of the threat of sea level rise inside the nest and the importance of nest shading. With satellite telemetry, researchers can track turtles when swimming from one place to another. These satellite tags will not harm the turtle and will eventually fall. This data will tell you where the important diet is located, help you understand the movement pattern and help you predict where the sea turtle will contact the fishery and its fishing gear.
