This document summarizes the impacts of global agricultural weather in 2010 and provides an outlook for 2011. In 2010, weather events like droughts in Russia and Argentina impacted wheat production. Late-year droughts in Brazil and India reduced sugar output. High commodity prices resulted from tight supplies. Going forward in 2011, key factors to monitor include energy prices, global supply and demand balances, and weather conditions during crop development and growing seasons. La Nina conditions could significantly influence 2011 crop yields.
