Sea Turtles

Sea turtles in Costa Rica are said to be "Casualties of Global Warming". With the rising temperatures sea turtles are in great danger. Unlike other mammals who's genes determine their gender, temperature determines the sea turtles gender. If the temperature is higher than 86 degrees, the turtles are all females. Above 93 degrees they are boiled eggs. This will be a problem when the temperatures start to rise permanently there will be no male turtles to mate with the female turtles. To help the turtles scientists are artificially cooling nests with shade or irrigation. “The climate is changing so much faster than before, and these animals depend on so much for temperature.” Carlos Drews, the regional marine species coordinator for the conservation group W.W.F.

Walruses

Global warming is impacting arctic marine mammals severely, especially walruses. The arctic ice is retreating and making life harder for walruses. United States scientists found around 121 dead walruses off the coast of Alaska. The walruses that were found dead had been trampled on from other walruses, from being on a small piece of ice which scientists say is very unusual. Scientists say that there have been stampedes before, from hunters, but these stampedes they are seeing now are not the same.
