As temperatures have risen, populations of the American pika have moved from lower elevations to cooler climes upslope.
Enlisting Endangered Species As a Tool to Combat Warming
Environment 360
by todd woody
While a high-profile battle raged over listing the polar bear as a threatened species due to melting Arctic sea ice, U.S. environmentalists were quietly building a case to protect a critter closer to home, one whose existence also seems gravely threatened by a warming world.
A pocket-sized member of the rabbit family with a distinctive squeak and large ears that frame dark eyes and a button nose, the American pika lives on rocky slopes high in alpine mountain ranges from the Sierra Nevada to the Rockies. Sporting a thick gray-brown coat, the pika does not hibernate and so maintains a high internal temperature to survive frigid winters. Because it can’t turn off its heater, the animal can die in the summer if its body temperature increases by as little as 3 degrees Celsius (5.4 F).

What's a Carbon Footprint?
A
carbon footprint is a "measure of the impact human
activities have on the environment in terms of the amount of
green house gases produced, measured in units of
carbon dioxide". It is meant to be useful for
individuals and organizations to conceptualize their
personal (or organizational) impact in contributing to
global warming. A conceptual tool in response to carbon
footprints are
carbon offsets, or the mitigation of carbon emissions
through the development of alternative projects such as
solar or wind energy or reforestation. A carbon footprint
can be seen as a subset of earlier uses of the concept of
ecological footprints.
