Scientist disputes claim that 2015 was warmest year on record

Daily Caller:

Dr. Richard Lindzen is anything but convinced by headlines claiming 2015 is the warmest year on record. He says what’s most important is that climate models have been over-predicting warming for more than 40 years.

“Frankly, I feel it is proof of dishonesty to argue about things like small fluctuations in temperature or the sign of a trend,” Lindzen, a climatologist at the Massachusetts Institute of Technology, tells the science blog Climate Depot. “Why lend credibility to this dishonesty?”

“All that matters is that for almost 40 years, model projections have almost all exceeded observations,” Lindzen says. “Even if all the observed warming were due to greenhouse emissions, it would still point to low sensitivity.”

When your projections are wrong , it means you have used invalid assumptions.  The problem witht eh global warming crowd is that they can't even figure out which of their assumptions is wrong so they keep using the same ones over and over and keep getting it wrong.
