Computer models of climate change have been dead wrong, yet alarmists aim to quell debate.

I repeat: I’m not a global-warming believer. I’m not a global-warming denier. I’ve long believed that it cannot be good for humanity to be spewing tons of carbon dioxide into the atmosphere. I also believe that those scientists who pretend to know exactly what this will cause in 20, 30, or 50 years are white-coated propagandists.

“The debate is settled,” asserted propagandist-in-chief Barack Obama in his latest State of the Union address. “Climate change is a fact.” Really? There is nothing more anti-scientific than the very idea that science is settled, static, impervious to challenge. Take a non-climate example. It was long assumed that mammograms help reduce breast cancer deaths. This fact was so settled that Obamacare requires every insurance plan to offer mammograms (for free, no less).

Now we learn from a massive randomized study — 90,000 women followed for 25 years — that mammograms may have no effect on breast-cancer deaths. Indeed, one out of five of of those diagnosed by mammogram receives unnecessary radiation, chemo, or surgery.

So much for settledness. And climate is less well understood than breast cancer. If climate science is settled, why do its predictions keep changing? And how is it that the great physicist Freeman Dyson, who did some climate research in the late 1970s, thinks today’s climate-change Cassandras are hopelessly mistaken?  Read rest of article here.
