The tropical plants and animals might be facing a bigger threat then the polar regions. Robert K. Colwell said that the tropics is already a hot how could global warming harm tropical species?
So Robert K. Colwell explained that some tropical species are living near there maximum temperature. Robert K. Colwell researched that the temperature 5.8 degrees Fahrenheit. Tropic species with small range would have to shift thousands of kilometers north or south. Warm climates have already scrammbled small mammals in Yosemite National Park. For some high elevated mammals like alpine chimpmunks have shrunk. However, mammals living at low elevation, like harvest mouse they have expanded their ranges in higher reaches. As you can see global warming is changing our world upside down.
