Roy Spencer, CLiMatE DeNIer!!111

Just throwin' this out there:
   How can such [inaccurate] models, which are increasingly portrayed as accurate, be defended with a straight face for energy policy decisions? The amount of warming they produce is not based upon physical first principles, as is often claimed. That some warming should occur is based upon fairly solid principles, but the amount of warming from increasing CO2 is entirely debatable.
   The dirty little secret is that the models are tuned so that only increasing CO2 causes warming, since the various uncertain sources of natural climate change are either not known well enough to include, or are purposely programmed out of the models. (How do I know? Because NONE of the natural energy flows in and out of the climate system are known to the accuracy [about 1%] needed to blame recent warming on increasing CO2, rather than on Mother Nature. Those natural energy flows in the models are simply forced to be in balance, and so the cause of model warming ends up being anthropogenic. Thus the models use circular reasoning to establish human causation.)
   The fourth and fifth questions have to do with whether we can really reduce CO2 emissions as long as humanity needs fossil fuels to reduce poverty and create prosperity. I have nothing against alternative energy sources per se, as long as they are practical and cost-competitive. Everything humanity does requires energy, and as long as China and India continue to reduce poverty with ever-growing usage of fossil fuels, global CO2 emissions will continue to increase, no matter what the United States does. With about 1 billion people in the world still without electricity, I believe it is immoral to deprive them of access to affordable energy.
   Out of the 5 Big Questions, which are most important? Ultimately, economics is what rules peoples lives. Poverty kills, and forcing people to use more expensive energy will worsen poverty.
   In France we are seeing the violent push-back against green energy policies (among other , mainly economic, issues), and we havent even yet reached the point where policies will reduce future CO2 emissions by enough to measure the effect by the end of this century in terms of global temperature. So, if you think the Paris riots are bad, wait until you see the public response to policies that will reduce future CO2 emissions by, say, 50%.
   But we cannot ignore the science. What if the science was absolutely certain we were in for 20 deg. C of warming and a collapse of the Antarctic ice sheet, with 200 ft. of sea level rise? Then humanity might be willing to make large sacrifices to save itself. So, the science does matter… the question is, can it be trusted?
   Based upon the observed rate of global warming (which is too small for any individual to feel in their lifetime), and failed climate model projections, I’d say the current state of the science is not yet ready for primetime.
   For now, the science supports some modest and mostly harmless warming, but not enough warming to justify CO2 emissions reductions that would destroy the global economy, worsen global poverty, and have no measureable effect on global temperatures by the end of this century anyway.
