It was nice to see you shortly at the IPCC meeting in Paris. I know that
you are invited to a lecture in the Academy of Sciences on March 5th.
The meeting is organised by Academicians such as Vincent Courtillot, who
is popularizing alternative views on climate change in the earth science
communities in France, and a good friend of Claude Allegre, another
geochemist who took positions arguing that there is no demonstration on
the role of human activities on climate, that climate models have no
demonstrated capabilities and that a global warming of 2�C has no meaning.
I am just writing this email to you after some arguments with these two
scientists (who are leading scientists of their own research fields). I
would just like to suggest that it would be nice to come prepared for
such a meeting, and give you a few arguments developed by these two
1) C. Allegre : global temperature estimates are not possible, there
were only 10 thermometers in the world 100 years ago (published 3 times
in 2006 in French newspapers such as l'Express or Le Monde)
(it would be interesting to show a map with the location and number of
thermometers used for your estimates)
2) V. Courtillot : has published a few papers on solar activity,
magnetic field and climate. The latest one is attached. He claims to
have used a global temperature dataset of yours but I have some doubts,
since the initial citation is from a paper by Solanki (it is somehow
indirectly, probably through a collaboration with Russian scientists).
He is working on temperature records from the Arctic (I guess local
data) and suggests that the 1940s period is warmer than the last decades.
We have interacted by email last week and apparently he wants to show
that your temperature series is not correct.
(it would be interesting to show the comparison between the global
temperature record and the estimates for various latitude bands).
