The American Pika and Global Warming
Moderation Note: These posts were moved from the thread "My Belief in Global Warming is Getting Shaky" because they deal with a more specific subject than the general discussion of anthropogenic global warming.
Consider the American pika.

As they live in the high and cooler mountain regions, they are very sensitive to high temperatures, and are considered to be one of the best early warning systems for detecting global warming in the western United States.[8] Because their regular habitat's temperature rises, the American Pikas move higher up the mountain.[6] Scientists report that pikas can die within an hour if the outside temperature reaches above 23°C (75°F).[6]

Does it matter to humans if the pika disappears? Not in the big scheme of things.
Should we be concerned by its disappearance? Certainly, imo!
