Antarctica could go green as a result of climate change, scientists warn

Man-made climate change could turn Antarctica green, with plants colonizing the land as ice sheets shrink, scientists have warned. Experts believe clues about the future of the planet can be gleaned from the Pliocene period three million years ago the last time carbon dioxide levels in the atmosphere were as high as they are today.
