Developed by the Scottish Executive Development Department Environment Statistics Branch, the Scottish Environment Statistics Online (SESO) Web site provides those users interested in Scotland's environment with valuable information that spans a wide range of years. Especially heavy with data in the last ten years, SESO covers numerous topics: Climate Change and the Ozone Layer, Air Quality, Radioactivity, Noise Pollution, Land, Water, Conservation, Wildlife, and Waste and Recycling. After selecting the desired subtopic and year, users receive results either in HTML or Microsoft Excel (.xls) format, along with source information and relevant links. Perhaps the most interesting feature is the commentary provided with each subtopic; for example, when viewing Annual Land Temperatures Records (tiered below Climate Change and the Ozone Layer), a brief commentary about the greenhouse effect is available. Researchers and scholars, as well as interested casual readers, should find the site worthwhile.
