Agriculture in a changing climate

Every now and then I’ll run across an article about the “good side” of climate change. It will be a boon to agriculture. Not everyone agrees with that cheery assessment. Some say there are problems ahead:

Douglas Fischer of The Daily Climate reports experts at the American Geophysical Union have concluded weather “driving many of the globe’s great breadbaskets will become hotter, drier and more unpredictable,” making farming increasingly difficult. Scientists studied severe drought in East Africa, sediment cores from New York marshes, drought in Australia and the western U.S. to determine this conclusion. Scientists told Fischer other factors adding to climate change’s impact on crops include population growth, deforestation, and policy choices.
