For GSS Climate Change chapter 8. Excerpt: ...The Illinois researchers are trying to move past just documenting the potential trouble, though. The bigger question is: What can be done to make crops more resilient? That has lately become an urgent topic. For decades, many climate experts were relatively sanguine on the issue, thinking that warming in frigid northern countries would benefit crops, helping to offset likely production losses in the tropics. Moreover, some research suggested potentially huge crop gains from a sort of counterintuitive ace in the hole: the very increase in carbon dioxide that is causing the planet to warm. ...The tests so far have confirmed the beneficial “CO2 fertilization effect,” as it is known. But in field conditions, the boon to the crops was not as great as in earlier greenhouse experiments, and probably not enough to offset the heat and other stresses of a warmer planet. “It’s there, it’s real, but the question is, how much is it going to help?” Dr. Leakey said.... http://www.nytimes.com/2014/09/23/science/testing-future-conditions-for-the-food-chain.html.
