Read here. The IPCC has been a literal cornucopia of bad climate predictions, which seem to be never ending as new climate research is accomplished and published. Another recent example of this phenomenon is a study, by Gabriel Vecchi and Thomas Knutson, that conclusively finds that the predicted huricane increase due to global warming has not happened.
"Prior to the satellite era (i.e., before 1966), most of the information about tropical cyclones in the Atlantic ocean came from either ship tracks (most of which tried to avoid the storms) or when the storms passed close enough to be detected from land. This tended to leave a lot of the Atlantic Ocean basin unmonitored. And in these observation-free areas, hurricanes may have come and gone without being detected..."After adjusting for the estimate of missed hurricanes in the basin, the long-term (1878–2008) trend in hurricane counts changes from significantly positive to no significant change (with a nominally negative trend). The adjusted hurricane count record is more strongly connected to the difference between main development region (MDR) sea surface temperature (SST) and tropical-mean SST than with MDR SST. These results do not support the hypothesis that the warming of the tropical North Atlantic due to anthropogenic greenhouse gas emissions has caused Atlantic hurricane frequency to increase.""
