Document Summary

All three are greenhouse gases: co2 has been 180-280 ppm over the last 800,000 years, except since the industrial revolution, humans are responsible; by 2100, atmospheric co2 will reach to be. 550-900 ppm: since the industrial revolution, the number of extinctions has dramatically increased (from a few to more than 50,000), humans had more impact on the atmosphere than any other single organism in earth"s history. How does past earth system engineering compare to the future: scale: in the past, it was more local, less global, intent: in past, effects were unintended and unanticipated.
