Al Gore's untruths grow more extreme Al Gore lies: "We're getting closer to a political tipping point," Gore said. These extreme weather events, which are now 100 times more common than 50 years ago, are really capturing people's attention. Gore is flat-out wrong, as last year's report by even the Intergovernmental Panel on Climate Change makes clear: Overall, the most robust global changes in climate extremes are seen in measures of daily temperature, including to some extent, heat waves. Precipitation extremes also appear to be increasing, but there is large spatial variability... There is limited evidence of changes in extremes associated with other climate variables since the mid-20th century... Current datasets indicate no significant observed trends in global tropical cyclone frequency over the past century â¦ No robust trends in annual numbers of tropical storms, hurricanes and major hurricanes counts have been identified over the past 100 years in the North Atlantic basin... In summary, there continues to be a lack of evidence and thus low confidence regarding the sign of trend in the magnitude and/or frequency of floods on a global scale... n summary, there is low confidence in observed trends in small-scale severe weather phenomena such as hail and thunderstorms... In summary, the current assessment concludes that there is not enough evidence at present to suggest more than low confidence in a global-scale observed trend in drought or dryness (lack of rainfall) since the middle of the 20th century... In summary, confidence in large scale changes in the intensity of extreme extratropical cyclones since 1900 is low... The only thing that's increased 100-fold since 1950 is extreme scaremongering by the likes of Gore, who is so reckless with the truth that journalists who treat him as an oracle have betrayed their craft. There is no excuse for Gore being so wrong, and no excuse for journalists not picking him up on it.
