Owen. UAH shows no warming from the beginning (1978) until 1997. Then we had the big ENSO which of course has no trend. Then from 2001 until now there is also no warming, but this flat period is higher than the prior flat period. This is a one shot step function, not 30 years of warming. Moreover there is no provision for such a step in AGW. I think UAH falsifies AGW.
