We should maintain perspective amid the global warming hype foisted upon us by the zealots who claim we must radically revamp our world in order to save it. The period of weather record keeping is short, relative to climate change and many factors influence the data now recorded.
''In the United States,'' Burt writes, ''weather records have been maintained by the official weather services since about 1870. In the 50 preceding years, records were kept intermittently by individuals and by some institutions, including the Smithsonian Institution.'' The figures we have ''represent only a fraction of human experience with weather,'' but may be used as a ''yardstick'' to determine climatic trends. By this yardstick, the weather is not becoming more extreme.
