RSS & UAH Update

January 9, 2013

By Paul Homewood


Both satellite datasets are out for December – and both are substantially down.



UAH – Down from 0.28 to 0.21.

RSS – Down from 0.19 to 0.10.



These numbers reflect the fizzling out of the small El Nino, that peaked in June – August. Since September, RSS has dropped 0.28C, with UAH also down by 0.13C. (This of course was the El Nino that was not, according to the UK Met Office!)


Full graphs etc once GISS and HADCRUT are out. Meanwhile, just consider that the 2002-2011 average for RSS was 0.26C, and UAH was 0.19C. It will be interesting if Roy Spencer’s new V6.0 comes closer to RSS, when it is ready.

Either way, even with currently neutral ENSO conditions, there has been no warming for 10 years on either set.

    What I find odd from the Met Office is that despite lengthy diatribes on 2012 UK rainfall they have not once mentioned the global factors that may have had some influence. Hurricane activity in the Atlantic basin this year was unremarkable (20th in a series beginning 1950 for ACE) and as you mention above, ENSO conditions are neutral.

    Hansen predicted a Super Duper El Nino but it looks like a lot a La Nada.

    Odd, too, isn’t it, that Hansen is never called out for his failed predicitions? Same with Ehrlich of “The Population Bomb” infamy; all his predictions were remarkably wrong.

    Ehrlich: The Wrongest Professor in The United States, maybe anywhere. That takes some doin’.
