Read here. Bozo climate predictions appear to be the IPCC's raison d'être, which they definitely excel at. The latest bozo climate prediction found to be erroneous is that global warming, due to human CO2 emission increases, will cause more precipitation, thus causing more floods of greater frequency and intensity. Fortunately for the world, the IPCC is wrong again.
Bouziotas et al. determined with 50+ years of empirical evidence from 119 stations that the frequency and intensity of floods has not increased and may actually be slightly decreasing. (click on image to enlarge)
"Analysis of trends and of aggregated time series on climatic (30-year) scale does not indicate consistent trends worldwide. Despite common perception, in general, the detected trends are more negative (less intense floods in most recent years) than positive. Similarly, Svensson et al. (2005) and Di Baldassarre et al. (2010) did not find systematical change neither in flood increasing or decreasing numbers nor change in flood magnitudes in their analysis."..."The chart on the left shows the percentage of the positive and negative slopes of the trend lines, for all years and for the period after 1970 respectively. Contrary to what is believed, the percentage of increasing trends is lower than that of decreasing trends, particularly in the most recent period."
