I've been checking my calculations and have added some more screen shots to
the Picasa web album at:

I put in a screenshot of "Figure 7" from Eschenbach's article, showing the
Raw and Adjusted temperatures at Darwin airport. The figure is rather
confusing as the black line on Fig 7 shows that the pre-1941 data was
adjusted DOWN by 2C (presumably because the absence of a cover led to
artificially high temperatures), but Eschenbach has aligned the two series
(raw and adjusted) look the same before 1941 and that therefore the series
looks elevated post 1941 with respect to the raw data.

However, I also added in the album the result of showing Raw and Adjusted
using the applet at
(which Eschenbach also used earlier in the article).

In that graph, you will see that the pre-1940 data was adjusted down, and
that post 1940 the two series look remarkably similar. Hence no elevated
trend appears to have been manufactured by the adjustments.

Furthermore, I calculated the trendline post 1963 for both raw and adjusted
and they both show a decline of 0.84 degrees per century.

By contrast Eschenbach claims the trend is +1.2 by plotting the trend using
the unreliable pre-1940 data.

When I first read the Eschenbach article I was really interested - it seemed
very plausible and I was prepared to be convinced that there had been data
fiddling in the adjustments. But in order to verify this, I had to examine
the data myself. I got the data and examined it with an open mind. I was
extremely surprised to find that the adjusted data fitted so exactly over
the raw data in the post 1963 data. I did not expect to see that.

So I am absolutely disgusted to find that it appears to be Eschenbach who
is doing the fiddling. I don't think even Answers in Genesis have engaged
on fabrication and deception on this level.

If this is the sort of tactic the global warming skeptics (or sceptics as
we say in England) are employing, then I also add myself to the list of
people who have become more convinced of the truth of AGW as a result of

If anyone wants to verify my calculations, please email me privately and
I'll send you an Excel 2007 spreadsheet containing all the data I got from
the GISS website and the charts derived from them.

Personally I think people should verify my work. After today I wouldn't
trust ANYONE writing about it!
