Summary Many climate scientists have suggested that anthropogenic emissions of greenhouse gases may create severe climate problems for Britain; however, the potential cooling effects of sulphur dioxide are widely acknowledged. In this investigation, we analyze British mean annual temperature, mean annual precipitation, and mean diurnal air temperature range over the period 1929–1988. Our analyses of these records reveal (a) a shift in the early 1950s away from warming and toward cooling, (b) a relative decline in maximum air temperatures when compared to minimum air temperatures, (c) a strong decline in the diurnal air temperature range and (d) a significant linkage between diurnal temperature range and precipitation. Given these signals in the observed climate record, it would appear that SO2 rather than CO2 has been the major anthropogenic climate influence in Britain over the past four decades.With 6 Figures 相似文献
