Making a Lush, Green Planet
Increased CO2 is helping plants grow around the planet. It seems that there are two effects at play. CO2 is good for plants, a type of fertilizer. CO2 also helps plants use water more efficiently. A third effect of CO2 is on rainfall. This one is so far unresolved: many models (and nearly all the press) predict that a hotter planet will be dry. Others (and the evidence so far) say that warmer means wetter. Beyond dispute, is that so far the increase in carbon has correlated to a greener planet.

Update (Nov23'14) Test are coming in improved photosynthesis mechanisms. Cyanobacteria are related to C4. I'm not sure about the High Yield Rice.
