The problem with the global warming scientists and their models are that they never real predict what has or will happen. Another interesting paper disproving the so call tipping point of the hoaxers. A paper published today in the Journal of Climate finds that relative humidity has been decreasing 0.5% per decade across North America during the 62 year period of observations from 1948-2010. Computer models of AGW show positive feedback from water vapor by incorrectly assuming that relative humidity remains constant with warming while specific humidity increases....."Over 1/4 billion hourly values of temperature and relative humidity observed at 309 stations located across North America during 1948-2010 were studied...The averages of these seasonal trends are 0.20 C/decade and 0.07 hPa/decade which correspond to a specific humidity increase of 0.04 g/kg per decade and a relative humidity reduction of 0.5%/decade."" [V. Isaac and W. A. van Wijngaarden 2012: Journal of Climate] Conclusion: The IPCC alarmist global warming tipping point does not exist over the long term - instead, over periods less than a decade, the climate will likely return to an equilibrium position due to built-in negative feedbacks.
