The American pika are small, cute mammals that live in broken rock habitats or talus fields high in the mountains above treeline. Adorable as they are, these critters might have a serious story to tell about the impacts of climate change. Research is showing a correlation between the loss of ice and permafrost under the talus, and the disappearance of the animals. As temperatures rise, where pika live could indicate the health of a watershed—and foretell our future water supply. For H20 Radio, Frani Halperin and Jamie Sudler report.
