If that’s the case, then we are probably trying to redesign the global economy for nothing.” It may well be that it is impossible to make long-term predictions about the climate – it’s a chaotic system after all. “It’s not just the fact that climate simulations are tuned that is problematic. Yet these fallible predictions, otherwise known as scenarios, are used by politicians, environmental advocacy groups, and energy firms to set public policy and future energy plans. Current climate model predictions diverge from historic reality when viewed over decadal time-scales. These problems are serious enough to cast doubt on the ability to construct such a climate forecasting system. She has authored (via the GWPF who reformatted it) “Climate Models for the Layman” in which the fundamental problems inherent in computer modeling are laid bare. Professor Curry, the author of over 180 scientific papers on weather and climate, recently retired from the Georgia Institute of Technology where she held the position of Professor and Chair of the School of Earth and Atmospheric Sciences. Now Judith Curry has had the courage to note the absence of clothes on the climate-computer emperor. Short term changes are known as weather, and weather prediction accuracy has improved out to a week or so over the decades. Climate behavior aptly fits the definition. Such systems are characterized by the fact that tiny changes in initial conditions may result in wildly different final outcomes over a period of time. The serendipitous discoverer of chaos theory postulated “is there such a thing as a climate?” Is there a definable “normal global climate” from which deviations might be termed abnormal? His 1965 paper includes “…if in addition the present state or the present and past states are not known with complete accuracy, any forecasting procedure will lead to poorer and poorer forecasts as the range of prediction increases, until ultimately only the periodic component can be predicted in the far distant future.” His statement is a description of what has become known as chaotic behavior. Massachusetts Institute of Technology pioneering meteorologist and mathematician Professor Edward Lorenz doubted this ability in the 1960’s. At the current state of scientific knowledge, such belief is intellectual hubris masquerading as achieved scientific endeavor. This has generated a belief system…belief that all variables which drive global climate at all time scales have been identified, quantified as to individual contribution and interactions, and that chaotic variability is foreseeable. Amongst those individuals are those divining climate with climate computers in which are embedded general circulation models. Some say that “God” might reside in a computer…the Deus ex Machina, literally means “god from the machine”.

Reddit user ArticxM00N129 went from 301 lbs. The gal above dropped all the way to 115 lbs. This flower print enthusiast lost track of how much weight she lost in five years, but the before and after pictures speak for themselves. In a little over two years, this dude lost 235 lbs. In 18 months, Reddit user Ashle圓nb lost 165 lbs. This Reddit user dropped 211 lbs., as she now stands at 173 lbs. Then he went to Six Flags to celebrate with a cat and a rooster. This fabulous fellow known as CupcakePanda on Imgur lost 150 lbs. The men and women below decided to go through the rigors that come with working out and eating well in order to lose insane amounts of weight, thus adding years to their life.Ĭheck out some of the best transformations below: While I continue to believe that the thought of hanging out at the gym everyday sounds like a punishment for the various sins I’ve committed, it can actually do wonders not only for your body, but for your life.
