Oh... Your disinformation comes from a green pressure group. That explains it. Their future depends on alarming pronouncements from models that haven't been validated. Bjørn Lomborg reminds us that 2013 is the 40th anniversary of the Limits to Growth, which used state of the art computer models that were not validated to predict that humanity faced a devastating collapse from the lack of food, oil, other commodities, etc. Now I see we are using unvalidated computer models to project "climate extremes" and other horror stories to prop up a failing theory of the catastrophic effects of fossil fuel use. Too bad the earth isn't cooperating. You will have to find another scare story to replace the last two that failed. Ocean acidification anyone?...

Even the IPCC, widely regarded as an unbiased source of information :-) knows this.

Here are a few excerpts from the IPCC AR5 WG1 chapter 2: (taken from Roger Pielke's testimony to the Senate)

“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 … 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”
“In summary, there is low confidence in observed trends in small-scale severe weather phenomena such as hail and thunderstorms because of historical data inhomogeneities and inadequacies in monitoring systems”
“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 due to lack of direct observations, geographical inconsistencies in the trends, and dependencies of inferred trends on the index choice. Based on updated studies, AR4 conclusions regarding global increasing trends in drought since the 1970s were probably overstated. However, it is likely that the frequency and intensity of drought has increased in the Mediterranean and West Africa and decreased in central North America and north-west Australia since 1950”
“In summary, confidence in large scale changes in the intensity of extreme extratropical cyclones since 1900 is low”

Roger: "There is really not much more to be said here -- the data says what it says, and what it says is so unavoidably obvious that the IPCC has recognized it in its consensus".

I'm sure thankful the data doesn't match the models. Now can you guys find something productive to do with your money that will actually help humanity?
