1. American Pikas Pikas are small rabbit-like animals that live high in the mountains on rocky, talus slopes in the Great Basin. Warming here has contributed to the extinction of 7 of 25 populations of these animals. They are very sensitive to temperature changes and have no where to migrate to. (Jensen)

2. Bighorn Sheep Bighorn sheep face the same problem that pikas face; they also live high in the mountains and have no where to go in order to find similar temperatures The pika and bighorn sheep are a good indication of how global warming is affecting animals because they do not suffer a lot of direct human impact. The terrain is either protected or too rough for people. (Jensen)

3. Butterflies Different species of butterflies in both the western US and Europe are expanding their ranges north 2/3 of 57 species of European butterflies have moved their ranges as far as 240 km in the 20th century (Jensen)

4. American Alligators American alligators range from the Carolinas south to Florida and west to Texas. They are appearing further north than before Rising sea levels could force them even further inland. (Tangley)

5. Snails, Sea Stars, and other Intertidal Animals In Monterey Bay, CA, the ranges of intertidal invertebrates has been shifting northward for the past sic decades as sea and air temperatures rise (Tangley) Back to Student 10 Home
