A caribou on the rocky tundra of western Greenland. Records show that arctic sea ice is at its lowest point in 1,500 years and continues to melt at an accelerated rate. In fact, over the past several decades the Arctic has warmed at twice the global rate. Researchers are studying how ecological communities in the Arctic may be affected by its continued and even accelerated melting in the decades to come.
