> In nature plants aren't CO2 limited, typically they are either nutrient, light, or usually water limited; and the warming planet is exacerbating water distribution issues Plants actually require extra water when CO2 levels are low, such as they are currently, which is why we see so much desertification of the planet. High CO2 levels reduce plants need for water, reducing desertification
