    I think he just proved that tropical rain forest don;t exist because it is to hot and the water would evaporate.

    And so you cackling hyenas cannot comprehend anything above the grade school level. Surprise, surprise.

    SERC - Lab CO2: C3 and C4 Plants

    It turns out that the important difference between C3 and C4 species for rising CO2 levels is that C3 species continue to increase photosynthesis with rising CO2 , while C4 species do not. So, C3 plants that can respond readily to higher CO2 levels, and C4 plants can make only limited responses.

    Thus increased CO2 likely will mean that some plant species will be stronger, more prolific, and may overwhelm those less able to benefit. The nature of plant populations in various areas probably will change; more sedges in place of grasses in marshlands, for example, consequences we don't yet know.

    At our research sites, we are looking at how these different classes of plants respond to increased CO2 levels, and the broader implications for the ecosystems in which they live.

    That means that you agree that the article cited in the OP was wrong, as well as being overly simplistic, we would easily be able to take C4 plants and adapt them to the increasing CO2 levels, and other plants have an inbuilt ability to adapt already.

    In other words, the guy who wrote the blog doesn't know what he is talking about.

    Water is good for plants, so flood your fields with six feet of water, bound to do your crops worlds of good. The simpletons here are the idiots that state that there cannot be too much CO2 as far as plants are concerned.

    You do realize that Flood Irrigation is a MAJOR agricultural standard for the watering of crops, right?

    Fyrenza, welcome, you have come to the right place. Anyone that considers 6 feet of water over a field flood irrigation will feel right at home in the company of the loons like Walleyes, Suckee...., Doodeee.... and Frank.

    It actually does. I know a few farmers who look forward to floods because it brings in new soil, and rice farmers flood their fields because rice likes it.

    Tell the idiot to put a plant in a bag, fill it with pure co2 and see how it works out.

    Maybe after she's done with that she can explain to us the symbiotic relationship between Cecropia Peltata and the Azteca and Zacryptocerus ants........but I doubt it.:cuckoo:

    True, but irrelevant to the discussion. It would only make sense regarding this topic, if ALL agriculture was done that way.
