Document Summary

Have an arrow (they affect each other) Surface temp plant decomp cos production. Gas that were released is positive feedback where greenhouse gases are released. Negative feedback will cause it to self regulate. High reflection does not reflect as much heat. Reduction of ice more water more ice sheet erosion and cracks that accelerate melting. Blocks radiation for a few years before coming back to normal. Earth reacts to change and reacts against. No intelligent decision that is being made. Rock cycle would lower co2 and compensate for increase temperature.
