Caribou

Fewer caribou calves are being born and more of them are dying in West Greenland as a result of a warming climate. "Spring temperatures at our study site in West Greenland have risen by more than 4 degrees Celsius over the past few years," said author Eric Post. "As a result, the timing of plant growth has advanced, but calving has not." The phenomenon, called trophic mismatch, is a predicted consequence of climate change, in which the availability of food shifts in response to warming, whereas the timing of demand for those resources does not keep pace.
