Caribou


Caribou—such as this large-antlered specimen silhouetted
by Alaska's northern lights—are being affected
as global warming accelerates in the Arctic.
In Greenland, caribou time their births to coincide
with the blooming of tundra vegetation.
But as climate change causes plants to peak earlier,
caribou newborns that eat the plants face tougher odds for survival.
