Richard Keen, Ph.D., Emeritus Professor of Atmospheric Science, University of Colorado, Boulder, put it bluntly in a recent personal communication:

Climate Science has degenerated into a league of collaborators who suppress evidence, stifle dissent, censor unwelcome facts, and control the funding purse strings, all in the name of “settled science.”  In a way, the science is settled—the forecasts of catastrophic global warming are irreversibly wrong.  Over the past 30 year the evidence of human caused climate change is barely detectable, and over the past 20 years it is nonexistent. I am a long-time climate observer in the Colorado Rockies, a place predicted to be warming at a rate of 1 degree each 15 years.  Instead, since the start of the millennium, the local climate has cooled one degree.  To base any policy whatsoever on the output of models that can’t even get the direction of climate change correct is an errand of those who “professed themselves to be wise, but became fools” (Romans 1:22, paraphrased).
