As I recall your last post was shrieking about some
"serious human die-back", as a result of
"spewing atmospheric carbon".
If I understand that as meaning some sort of crisis or catastrophe, nothing in your links above say anything like that is going to happen.
I think all he's talking about is the ability of plants like corn to store higher concentrations of CO2 in Sheath cells.
http://www2.mcdaniel.edu/Biology/botf99 ... ark/c4.htmIt's nothing to worry about. Corn is doing fine in this time of elevated CO2.
$1:
The scientists gathered global production statistics for four leading crops--corn, wheat, rice and soybeans--that together represent about 64 percent of all calories consumed worldwide.
They found that production of these crops in the Northern Hemisphere has more than doubled since 1961
http://www.sciencedaily.com/releases/20 ... 142211.htmI'll tell you what though, if you're really worried the demon CO2 is going to kill your future corn, talk Barrack Obama into halting Al Gore's idiotic policy of turning corn into fuel. You'll have more corn than you know what to do with. And when you get him on the line ask him why I have to pay extra to have that ethanol crap taken out of my gas at the pump.
For the exact same reason they charged more for NOT putting lead into fuel as an additive back in the '70s, because they can.
As for the rest of your post, you can simmer down a bit. Turns out you don't need the edible part of the plant at all to make ethanol. When you harvest a field of corn, all the shit that's left over is good enough for producing ethanol. Turns out we can double-end almost any field crop growth for food AND fuel at the same time without losing ANY food growing capacity.
If you want more corn than you know what to do with, cut way back on the friggin' cattle ranches hacked out of the rain forests. Then we wouldn't have to waste so much arable land on livestock feed. The fast food industry can suck it up. North America needs another McDonalds, BK, Wendy's, Harvey's, Ardee's, Hardees, Krystal ad nauseum about as much as we need more crack and meth.
