This work was undertaken with funding for M.N. from the U.K. Natural Environment Research Council (Grant GR3/09721); for M.H. from the U.K. Department of the Environment, Transport, and the Regions (DETR; Contract EPG 1/1/48); and P.J. from the Department of Energy (Grant DE-FG02-98ER62601). The CRU precipitation, mean temperature, and diurnal temperature range datasets have been compiled over a number of years with support from the U.K. DETR and the Department of Energy. Data obtained from the Global Historical Climatology Network and the Carbon Dioxide Information Analysis Centre supplemented the CRU archives. Other data supplied by numerous national meteorological agencies, research organizations, and private individuals made this research possible, and these contributions, while too numerous to mention by name, are gratefully acknowledged. The Climate Impacts LINK Project (UK DETR Contract EPG 1/1/16) at the Climatic Research Unit provided computing facilities for this research.
