Climate Change May Not Benefit Crops

"Increasing levels of atmospheric carbon dioxide may not be as helpful to crops as previously thought, according to a new study. As global temperatures rise, soil moisture levels fall. Laboratory experiments suggested that the crop losses resulting from this loss of moisture would be offset by a boost in fertilization from rising levels of carbon dioxide. Now field studies show that carbon dioxide's beneficial effects are not nearly as strong in real crop-growing environments."

Darn and I thought maybe plants will right the balance somehow. though I suspect the experiment would be hard to do you need to create an enclosure to get balance of light for both control and experiment plants and only vary the CO2
