At least 18 U.S. federal agencies administer climate change activities, costing at least $77 billion between 2008 and 2013, yet they do not have a climate model that works.
Testimony to Congress: “When the “scientific method” is applied to the output from climate models of the IPCC AR5, specifically the bulk atmospheric temperature trends since 1979 (a key variable with a strong and obvious theoretical response to increasing GHGs in this period ), I demonstrate that the consensus of the models fails the test to match the real – world observations by a significant margin. As such, the average of the models is considered to be untruthful in representing the recent decades of climate variation and change, and thus would be inappropriate for use in predicting future changes in the climate or for related policy decisions.” ~ U.S. House Committee on Science, Space & Technology, 29 Mar 2017, Testimony of John R.
