You will find warming mostly happens over richly foliaged parts of the planet, and a relationship between plant water retention and atmospheric CO2 concentration. (Leaf stomata shrink or expand depending on carbon starvation; Larger stomata increase plant inspiration, and water transpiration.) This is more pronounced on bigger leaves, so it's not lawns you should be looking at, but the natural carbon sequestering agents known as trees.
