Professor Jeff Price, Department of Geological and Environmental Sciences, California State University, Chico is one of the lead authors on the Intergovernmental Panel Climate Change report, which was released beginning on Feb. 2. The report is used by policy makers in member nations of the Intergovernmental Panel and by other decision makers and scientists around the world.

Price contributed much of the writing on changes to ecosystems and extinction risks in the chapter "Ecosystems, Their Goods and Services" within the main report "Climate Change 2007: Climate Change Impacts, Adaptation and Vulnerability." He specifically covered biodiversity, adaptation and mitigation and valuing ecosystems.

Price makes several predictions in the ecosystems chapter, including that approximately 20-30 percent of plant and animal species assessed so far are likely to be at increased risk of extinction if increases in global average temperature exceed 1.5-2.5 degrees Celsius.

Price also predicts that millions more people will be flooded every year due to sea-level rise by the 2080s. Those densely populated and low-lying areas where adaptive capacity is relatively low, and which already face other challenges such as tropical storms or local coastal subsidence, are especially at risk. The numbers affected will be largest in the mega deltas of Asia and Africa, with small islands being especially vulnerable.

Price is co-author of "Fingerprints of Global Warming on Wild Animals and Plants," an article in the international journal "Nature." He is author of the joint American Bird Conservancy/National Wildlife Federation publication "The Birdwatcher’s Guide to Global Warming," as well as author of a number of scientific papers on the potential impacts of global warming on birds.

Price’s work has been the subject of Pulitzer Prize-winning cartoonist Steve Benson and is featured in the murder mystery "Death of a Songbird" by Christine Goff. Price was a featured speaker at the Conference on World Affairs in Boulder, Colo., last week.
