Earth in Its Final Century? by Martin Rees

Earth in Its Final Century?

by Martin Rees


Title Details

Running Time
17 Min.
British Cosmologist Sir Martin Rees gives a wise talk on the history and future of Earth in this TED Talk. Viewed as a whole the Earth has seen very gradual change in its 4 billion year history. Since the dawn of man though there has been some quite rapid change on the planet particularly in the last 2000 years. And in just the past 50 years the amount of carbon dioxide in the atmosphere has begun to rise abruptly, the planet has been emitting radio waves, and small metallic objects have begun orbiting the Earth and some have journeyed out of that orbit. With 6 billion years yet to come on Earth it remains to be seen what sort of life will inhabit it, and we will need the humane wisdom of the elder Albert Einstein to prevent catastrophe. This TED talk is available on MP3 audio download and streaming video.
