Antarctica as warm as South Africa 100 million years ago!

I've just been reading an interesting article in the Telegraph, about how Antarctica was as warm as South Africa, 100 million years ago!   It's fascinating to think about how the earth has evolved and how things have changed (and are developing) in our lifetime.  Both the last episode of the BBC's fantastic 'Earth: Power of the Planet' series, and also the fascinating documentary 'The Eleventh Hour' highlighted the fact that the earth will slowly recover and re-evolve long after humans have become extinct.  We are privileged to have the opportunity to learn about and discover the wild and wonderful landscapes during our lifetimes. That we should respect the environment is without question. Human presence is just a blip in the lifeline of the planet - a very humbling thought.
