| Description: |
An international team of scientists who monitor the rapid changes in the Earth's northern polar region say that the Arctic is entering a new state - one with warmer air and water temperatures, less summer sea ice and snow cover, and a changed ocean chemistry. This shift is also causing changes in the region's life, both on land and in the sea, including less habitat for polar bears and walruses, but increased access to feeding areas for whales.
