Cover image: Artist's conception of the impact of climate change on global agriculture and forestry. One of the challenges of the 21st century will be to increase food and timber supply to accommodate a human population of 10 billion while undergoing climate change. Success will require a steady stream of technical and institutional innovations. See the articles on pages 19680–19714, in which the lead authors of the chapter on food, fiber, and forestry in the recently released Fourth Assessment Report of the Intergovernmental Panel on Climate Change amplify their findings.
