Forget El Nino, the error bars from 1995 and the 2008 overlap which means there has been no statistically significant warming during that time. So says Richard Lindzen. And I think he is absolutely correct.
That strikes me as erroneous. You can’t just blankly state that because the lower bound of one error bar overlaps with the higher bound of a different error bar (and are these 1-, 2-, or 3-sigma error bars?) that there is no statistically significant trend. Error bar range is not considered when a significance test is done. Even I know that.
