Growing Disruption: Climate Change, Food, and the Fight Against Hunger , a September 20 report by Oxfam International, found that climate change impacts are expected to damage crop production and, as a result, harm food quality and human health. 2012 droughts led to a 25 percent cut in grain harvest in Russia and 25 percent cut in corn production in the U.S. Midwest. The report advocated for work to cut emissions and to create a sustainable food system.
