In this new effort, the researchers took a new look at the photosynthesis process and how it might be altered in the presence of increasingly higher concentrations of CO2. They found that as CO2 levels rose, plants altered the way they processed the gas, saving more of it to use as a fertilizer, which allowed the plants to grow bigger or to become more robust, which in the end meant more CO2 was taken out of the atmosphere. Not coincidently, the researchers note, their research showed that when plants were exposed to the same higher levels of CO2 as actually occurred over the past century, they were able to absorb on average 16 percent more CO2, which very nearly coincides with the 17 percent error difference earth scientists have found with their climate models.
Sounds like the forests and fields of the Climate Change future will be quite verdant and thus take more of the CO2 out of the atmosphere then the models predict. In any case it seems that models that are wrong so much of the time need to be fixed in order for us to get the complete picture.
