Nature's Great Events: The Great Melt

SYNOPSIS

As winter finally passes and the sun climbs over the Arctic, the 4,000,000 square mile ice-sheet rapidly begins to melt, revealing an archipelago of islands, channels and seas. For the masters of the ice, the polar bears, this is a moment of jeopardy but for others like the arctic fox, beluga whales, thousands of lemmings and immense flocks of birds this is the richest place on Earth.
