This is about, obviously, plants that get enough sun and water to see a huge crop yield differences.
Research results have shown that more plants are growing and adapting in higher latitudes. The irony is this. When CO2 concentration rises the photosythesis process becomes more efficient when it comes to cycling nutrients and water. This has been well documented. In one study it grew Sorghum bicolor grown in a 570 ppm CO2 environment had water-use efficiencies that were 9 and 19% greater than the control plants grown in ambient conditions in both well-watered and water-stressed conditions.
Conley, M.M., Kimball, B.A., Brooks, T.J., Pinter Jr., P.J., Hunsaker, D.J., Wall, G.W., Adams, N.R., LaMorte, R.L., Matthias, A.D., Thompson, T.L., Leavitt, S.W., Ottman, M.J., Cousins, A.B. and Triggs, J.M. 2001. CO2 enrichment increases water-use efficiency in sorghum. New Phytologist 151: 407-412.
So, increase in CO2 concentration of upward of 2000 ppm has an obvious benefit to plants.
While this sounds simple on the paper, this is not a good thing. Roads stop many species from following the plants up to higher latitudes. Other natural formations and habitats, that can't follow the plants when they move will also put more species under threat. It's like beating up the nature, and beliving it will be all fine. The bad news for us is that we are a part of this fine tuned nature that we are beating up.
New plants don't help against global warming because they are CO2 neutral, ie can't consume and clean out the high denisity of CO2 emissioned by humans, it have to be old growth forest, that we are chopping down at a high rate.
