The NOAA Paleoclimatology Program is responsible for this excellent resource on Drought in North America, described within a geological timescale. Specifically, the Website aims "to explain how paleoclimatic data can provide information about past droughts and about the natural variability of drought over timescales of decades to millennia." The site is organized into four main sections: The Beginning (an introduction); The Story (topics include What is drought? and Paleoclimatology and drought); The Data (The Instrumental Record, The Last 500 Years, Even Longer Records); A Final Word (covering drought and the future, and Global Warming scenarios). Each section includes detailed, illustrated information, with hyperlinks to related Websites. Whether for researchers interested in learning more about the utility of paleoclimate data, or educators seeking instructional materials, this Website is a well-designed and thorough resource.
