Did anyone read the sunday times today ,it shows how easily facts about

No I didn't see that article, but I did notice the sister daily paper's
article on the Himalayas and the effects of Chinas smoke stack industries
putting soot on the glaciers (in combination with AGW).

While on the subject of source data ,worldwide CO2 measuring equipment
over the years must have changed ,
did anyone calibrate the old equipment against the new.


How dumb do you think these guys are? The labs do inter comparisons and
tests using flasks of sampled air and reference materials.

Keelings basic technique for CO2 measurement hasn't changed all that much
but the error bars have become narrower as instrumentation has improved.
Scripps has put most of their data online:

Ronald Raygun had several goes at removing funding from Keelings long term
CO2 work because the evidence it produced was inconvenient and conflicted
with the Republicans trash the environment policies.

Ironically climate sceptic President Dubya had to give Keeling the US
National Science Medal in 2002 for his lifetimes work.

And it isn't just the concentration of atmospheric CO2 that is changing -
the isotope ratios are shifting to match the signature of the fossil fuel
CO2 we are burning at an increasing rate.

These days the methods are available relatively cheaply for anyone who
wants to do it for a few thousand pounds. The uniqueness of the Keeling
data is that he was the first to do it and it now covers many decades (and
several key locations).

Just to add to the conspiracy theory , I bet the new equipment gave
generally higher ,more sensitive and more accurate readings than the old
,so you of course will see a spike in the more recent levels


They give the same values with slightly tighter error bars. Measuring CO2
was pretty routine and well inside the instrumental capabilities even when
he started. The early kit was actually rather good with better than 3 sig
fig precision and accuracy. Depending on the monitoring station you also
see the annual CO2 change from seasonal photosynthesis which gives a
pretty good sanity check on their data.

Keeling's son developed a commercially available paramagnetic oxygen
monitor to a standard of reproducibility where it can measure the
corresponding decrease in oxygen concentration resulting from the
combustion process which requires more than 5 significant figures.

This shows that 43% of the CO2 we emit ends up in the oceans and is
causing measurable changes in acidity which will damage sensitive calcium
fixing organisms like corals.

It would be great to get hold of some old equipment and compare the new
to it.
What do you other cleaver newsgroup guys think.?


You are paranoid.

Martin: your Ronald Raygun remark immediatley finds you out as a liberal
BBC/Guardian totting left winger and in that role I would like you in as
many words as you choose; to enlighten us all as to the wonderful
environmental record of the old Soviet Union and China
