I rode up to NCAR earlier and went into their museum for my Trenberth provided weekly comedy. I was not disappointed.
This video explained how the North Atlantic Oscillation (NAO) affects winter temperatures in Canada and Europe. That part of the video was interesting and informative.
But then the stupidity began. This guy cherry-picked an interval starting in 1975 and ending in 2000 – which he blamed on CO2.
Had he included the entire time series, the audience would have seen that the NAO plummeted from 1995 to 2010, making his assertion about CO2 affecting the NAO completely mindless and absurd.
Had he wanted to prove global cooling, he could have done the same trick starting in 1930 and ending in 1975.
These are our country’s top climate scientists – and they would all fail freshman engineering classes for dishonesty and incompetence.
