Diedrich said in the Earth Day room that pikas are going to die because of rising temperatures.
Is this true?
Yes, it is true:
* Pikas live in boulder fields surrounded by meadows on mountain peaks. They avoid the summer heat by seeking the cool crevices under the boulders and by remaining inactive during warm periods.
* Despite the long, cold, snowy winters at high elevations, pikas do not hibernate.
* Pikas spend summers diligently gathering flowers and grasses and store them in “haypiles” for food to sustain them through the long winters.
* These “boulder bunnies,” which weigh only a third of a pound, must collect more than 60 pounds of vegetation to survive the winter.
* Global warming threatens pikas by shortening the time available for them to gather food, changing the types of plants that grow where they live, reducing the insulating snowpack during winter, and, most directly, causing the animals to die from overheating.

Because they live at such high altitudes, in some places they have no higher to go to stay cool and are dying out. However, all it not lost! They are being wiped out in many areas but doing well in others.
