Agreement is developing among agricultural scientists on the emerging inability of agriculture to meet growing global food demands.  The lack of additional arable land and availability of freshwater have long been constraints on agriculture.  However, the increased frequency of extreme and unpredictable weather events, in a manner consistent with the changes predicted by global climate models, is expected to exacerbate the global food challenge as we move toward the middle of the 21st century.
