   These last ten years just don't look all that flat to me.

"A word on scale:

Questions have been asked about why our graphics look so very
different from those frequently seen in the media and IPCC and ACIA
publications. Apart from the obvious differences stemming from our not
using flash graphics software, pretty pictures and 3D dinguses there
is one significant variation - scale. I could launch into longwinded
explanations but it is probably easier and more effective simply to
demonstrate. The graphs linked from the following thumbnails are all
generated with identical data:

There you have it, each graph produced from the best available data
(the same data) but all visually distinctive.

The first candidate, although lacking the amplitude to allow easy
detail examination, is perhaps the most visually accurate and least
useful. Clearly global temperature has been on an overall warming
trend through the series and this warming is very small compared with
say, seasonal variation. Likewise, the two order of magnitude
magnification of carbon dioxide (by scaling parts per million on a 10K
range) has made our trace gas visible while maintaining perspective
(two times a tiny fraction of the atmosphere still gives you a tiny
fraction of the atmosphere).

Our next graphic is a mixed bag, rather restrained in the temperature
variation when compared with most publications but sufficient to
readily observe variation. The representation of rapidly climbing
carbon dioxide is achieved by scaling against only a tiny portion of
the valid range. ACIA, in this graphic, manage to present virtually a
perpendicular change which gives the impression of being about 500%
over 'background' levels and fitted neatly to a representation of the
infamous 'hockey stick' graph when in fact the total change in
atmospheric carbon dioxide is under 35%. Oh well, that's the
impression they want to give, we suppose, although we think it an
appalling piece of chart work.

Finally, our third chart depicts unrestrained temperature variation,
utilizing maximum plot space in order to easily depict temperature
changes (albeit vastly magnified) and with a greatly magnified but
proportionately correct trace gas representation (316-377ppmv annual
CO2 (Keeling and Whorf, May, 2005), missing values omitted). This is
our preferred graphic and the style we present. Granted, it greatly
amplifies apparent temperature change and, if this worries readers
just visualize the world as a relatively flat 14 °C ± 0.7 °C and
you'll be in the ballpark."
