The IPCC Climategate scientists and their AGW alarmist brethren at national climate agencies predicted that global warming would increase precipitation in mountainous regions, thus causing more mud/debris slides. Per a peer-reviewed study of an area of the Swiss Alps, this prediction has failed miserably, like so many.
"The authors note that it has been suggested that global warming may increase the frequency of extreme precipitation events and, therefore, that it may enhance the occurrence of natural mass-movement processes such as debris flows in mountainous regions. In fact, they state in regard to this particular phenomenon that there is a "widely accepted assumption that climatic changes will univocally lead to an increase in event frequency."".....The two Swiss scientists found there were peaks in debris-flow activity "toward the end of the Little Ice Age and in the early twentieth century when warm-wet conditions prevailed during summers in the Swiss Alps," but they say they also observed "a considerable decrease in frequency over the past decades which results from a decrease in the frequency of triggering precipitation events.".....they add that their findings "are in concert with data from Jomelli et al. (2007), indicating that the most recent past (2000-2009) represents the period with the lowest frequency of debris-flow events since AD 1900," which latter decade is touted by climate alarmists as having been the warmest such period of the past millennium or more."
