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?

How about, "Roger tries desperately to show continued warming, but fools
no one."
