Climate change causing problem to breeding of sea turtles

Climate change is causing damage to many animal species around the globe, and famous sea turtles are one of the most affected species. The latest study has revealed that sea turtles could have severe difficulties with breeding in years to come, once climate change impact becomes stronger.

Every year at certain point of time sea turtles come to lay their eggs in the sand. Little they are aware of triple threat that is coming with climate change, in form of cyclones, rising seas and warming temperatures.

Scientists have studies the world's largest population of sea turtles in Australia's northern Great Barrier Reef, and they have concluded that blazing hot sands presents the greatest threat to the animals' breeding success over the long term. Short-term speaking sea level rise is likely to cause the most damage to breeding of sea turtles but by 2070, sands in many areas will be so hot that eggs will not be able to survive, and sea turtles will likely face extinction.

Sea turtles play very important role in marine ecosystems, and balance of these ecosystems will be severely damaged once these peace-loving animals stop grazing kelp and algae.

Climate change could bring sea turtles to the brink of extinction.

The effects of warming are already obvious, and the fascinating fact with the sea turtles is that sand temperatures play major role in determining the sex ratio of turtle eggs. Warmer temperatures of the sand do not only more females, but also reduced hatchling success, and more deformities. If temperatures of the sand rise above 91 degrees Fahrenheit (33 degrees Celsius), then the eggs die.

Since climate change impact is unlikely to be stopped we must look for alternative solutions like installing shady areas on the beach, replanting vegetation along beach edges to get more shades, or relocating eggs to cooler places. If we fail to come up with the adequate conservation efforts, then sea turtles will likely go extinct.
