Egg Laying Effected
Due to global warming
Sea Turtle Egg Laying is Affected by Global Warming!
Sea turtles egg laying is hugely affected by global warming. One way they are affected is by rising sand temperatures which is from increasing temperatures which results in decreased hatching rates or complete nest failure for sea turtles. There's already concern for sea turtles which is only 10% of what is hatched will only survive the first year of life. One final effect is that increased sand temperatures also affect hatchlings by altering their natural gender ratios which warmer temperatures make more female hatchlings.

Global Warming Affects Bird Egg Laying!
Many birds are laying their eggs earlier, one species in particular is the tree swallow. They are laying their eggs nine days earlier than usual. Weather and food supply are some of the main factors. If it is still cold they have to wait for it to warm up and the food supply to come out where as if it warms up faster they need to lay their eggs earlier.
Overall Egg Laying is Affected!
For all types of living organisms global warming has affected their egg laying. Such as when the sea level is rising from the melting of polar ice which is contributing to the loss of beaches and sea turtle nesting habitats. Also increasing in surface air temperatures causes hatchlings to come earlier. Another affect is for overall animals is that eggs being laid earlier can eventually cause extinction with some species.
Birds Migrating
Birds migrating somewhere warm so they can lay their eggs.
Polar Bear on Melting Ice
This picture shows a polar bear on melting ice which is because of global warming. When the ice melts it rises the sea level which causes loss of land and the loss of habitats to lay eggs.
Sea Turtle
This picture shows a sea turtle swimming through the ocean to get where it is going to lay it's eggs.
Dangers of Global Warming
Some bird species (as well as other animals) may go extinct. With global warming causing spring coming earlier and fall coming later birds can adjust but it will most likely take longer for the plants and vegetation that birds, or their prey, rely on to adjust. Without these plants birds can lose a home to nest and lay eggs on as well as a main source of food. Another reason is early migration, birds are migrating earlier or later and because of that the egg laying pattern is not staying consistent.
