The End of Autumn in the Arctic
In The End of Autumn in the Arctic, narrator Sir David Attenborough explains how the Sun is turning away from the Arctic and the temperatures are dropping. Watch sea ice form, polar bears return to the ice, and the tundra become ablaze with color as the leaves change from green to orange, yellow, and brown. This video is excerpted from BBC’s Frozen Planet, a series that shows a fragile world of beauty and hostility, where nature finds a way to survive and thrive in frigid conditions.
