This video examines what will happen to crops as Earth's temperature rises and soils dry out because of changing climate.

In this video, NOAA's Deke Arndt, Chief of the Climate Monitoring Branch at the National Climatic Data Center, recaps the temperature and precipitation data for the continental US in summer 2012. It describes how these conditions have led to drought and reduced crop yields.

This poster, viewable online, highlights some of the impacts of a global-average temperature rise of 4 degrees C above the pre-industrial age climate.
