Climate Change Will Impact Food Security


Climate change is likely to have far-reaching impacts on food security throughout the world, especially for the poor and those living in tropical regions, according to a new international report that includes three co-authors from the National Center for Atmospheric Research (NCAR). SDIM1431 copy The report, issued at the Paris 2015 United Nations Climate Conference warns that warmer temperatures and altered precipitation patterns can threaten food production, disrupt transportation systems, and degrade food safety, among other impacts. As a result, international progress in the past few decades toward improving food security will be difficult to maintain.  The report, Climate Change, Global Food Security, and the U.S. Food System, provides an overview of recent research in climate change and agriculture. Led by the U.S. Department of Agriculture and published under the auspices of the U.S. Global Change Research Program, it includes contributors from 19 federal, academic, nongovernmental, intergovernmental, and private organizations in the United States, Argentina, Britain, and Thailand.  “If society continues on a path of high emissions of greenhouse gases, there is no way around the fact that climate change is going to be a primary challenge for producing and distributing food,” said NCAR scientist Claudia Tebaldi, a co-author of the report. “If society lowers emissions, climate change will still be a stressor on food security, but other factors such as socioeconomic conditions could be more critical.”
