A Century of High and Low Snowfall Extremes in the United States
Kunkel, K.E., Palecki, M.A., Ensor, L., Easterling, D., Hubbard, K.G., Robinson, D. and Redmond, K. 2009b. Trends in twentieth-century U.S. extreme snowfall seasons. Journal of Climate 22: 6204-6216.
Based on their analysis, the seven scientists of Kunkel et al. (2009b) found there were "large decreases in the frequency of low-extreme snowfall years in the west north-central and east north-central United States," but that they were "balanced by large increases in the frequency of low-extreme snowfall years in the Northeast, Southeast and Northwest." All in all, therefore, they determined that "the area-weighted conterminous United States results do not show a statistically significant trend in the occurrence of either high or low snowfall years for the 107-year period."
Although climate alarmists continue to claim that global warming leads to more extremes (highs and lows) of all types of weather-related phenomena (such as floods and droughts, for example), this study demonstrates that such has not been the case with respect to snowfall averaged over the entire United States throughout the period of time -- the latter 100-plus years -- when the world's radical environmentalists contend that the earth warmed at a rate and to a level that was unprecedented over the past one to two millennia.
