Despite our _advice_ 
(http://www.realclimate.org/index.php/archives/2008/01/uncertainty-noise-and-the-art-of-model-data-comparison/) , people are still 
insisting that short term  trends are meaningful, and so to keep them happy, 
standard linear regression  trends in the ENSO-corrected annual means are all 
positive since 1998 (though  not significantly so). These are slightly more 
meaningful than for the non-ENSO  corrected versions, but not by much - as usual, 
corrections for auto-correlation  would expand the error bars further.
