Is the earth getting warmer?  And the waters rising?   The True Believers (Al Gore and others)  are convinced that  that the earth is getting hotter.
And then  there are the Skeptics.   The Skeptics continue to say that there’s been no increase in warming for the last 18 years.  Skeptics have said that  the  18 year gap (no actual warming)  shows that  the models indeed  are wrong.
Now there’s new  evidence which shows  that the models are indeed wrong. See below:
A scientific consensus has emerged among top mainstream climate scientists that “skeptics†or “lukewarmers†were not long ago derided for suggesting — there was a nearly two-decade long “hiatus†in global warming that climate models failed to accurately predict or replicate.A new paper, led by climate scientist Benjamin Santer, adds to the ever-expanding volume of “hiatus†literature embracing popular arguments advanced by skeptics, and even uses satellite temperature datasets to show reduced atmospheric warming.
More importantly, the paper discusses the failure of climate models to predict or replicate the “slowdown†in early 21st century global temperatures, which was another oft-derided skeptic observation.
“In the early twenty-first century, satellite-derived tropospheric warming trends were generally smaller than trends estimated from a large multi-model ensemble,†reads the abstract of Santer’s paper, which was published Monday.
“Over most of the early twenty-first century, however, model tropospheric warming is substantially larger than observed,†reads the abstract, adding that “model overestimation of tropospheric warming in the early twenty-first century is partly due to systematic deficiencies in some of the post-2000 external forcings used in the model simulations.â€
The paper caught some prominent critics of global climate models by surprise. Dr. Roger Pielke, Sr. tweeted “WOW!†after he read the abstract, which concedes “model tropospheric warming is substantially larger than observed†for most of the early 21st Century.
