The trend is very much dependent on the latitude. If you look at the
figures for the various latitude bands, the positive trend is most
dramatic for 60/82, and nearly as strong for -20/20, whereas the trend
for -70/70 is almost zero - which seems to indicate that temperate
latitudes are not warming??

It's also time-dependent. Roger's not the only one who can draw pretty
graphs, but in this examplehttp://i55.tinypic.com/iwrg35.png *you can see
how useful a linear trend line is, depending on what you want to show.. The
data is from Roger's thoughtfully provided source. I added another trend
line that's probably a little more representative of what's been happening
lately.

Sure - if you think that leaving out 95% of the RSS data is
"representative". Using a 10-year data span, all you have to do is pick
the right El Nino peaks and troughs for your start and end-points, and
you can get any result you care for.

95% of the data? That's a bit of an exaggeration, Tom, unless someone hired
a TARDIS and took the satellites all the way back in time to 1811. Anyway,
that sort of illustrates my point. The full 30 years record DOES show
warming of course - no-one suggests it hasn't - but the LATEST data does
not. I took the last ten years worth of data and it shows that the LATEST
satellite data does NOT show "continued warming". Therefore Roger's subject
line is deliberately misleading. Now why is that so hard to understand?

Mainly because spinner is forgetting context, yet again. Factor in
ENSO.

Spinner doesn't and tries to spin the data to show no warming. Any
scientist looks at the trend, recognises there is noise around that
warming trend; recognises that the trend will *never* and can *never*
be linear and sees warming over time. A climate denier cherry-picks
two points from all the years within the scatter and says there has
been no warming.
