Document Summary

The greenhouse that is forming now will have great consequences on life and life systems that last for hundreds of thousands of years: desertification, sea level rise, ocean acidification. Implications for life: species extinctions, mass migrations, even greater disparity rich and poor, climate wars. Holocene: the time period where humans flourished (not too hot, not too cold) Anthropocene: time of the humans, we have changed the chemistry of the entire world (mountains, air, water, ecosystems including arctic and savannah) Planetary boundaries: safe operating spaces for humanity to exists within (from rockstrom et al.
