It looks like the hacker who was responsible for Climategate has just released a load more e-mails:
Climategate 2.0 « the Air Vent
A lot of e-mails just showing how they manipulated the IPCC report.
A few choice bits:
Mike, The Figure you sent is very deceptive [...] there have been a number of
dishonest presentations of model results by individual authors and by IPCC
We don’t really want the bulltulip and optimistic stuff that Michael has written
[...] We’ll have to cut out some of his stuff.
A growing body of evidence clearly shows  that hydroclimatic variability
during the putative MWP (more appropriately and inclusively called the
“Medieval Climate Anomaly” or MCA period) was more regionally extreme (mainly
in terms of the frequency and duration of megadroughts) than anything we have
seen in the 20th century, except perhaps for the Sahel. So in certain ways the
MCA period may have been more climatically extreme than in modern times.
Although I agree that GHGs are important in the 19th/20th century (especially
since the 1970s), if the weighting of solar forcing was stronger in the models,
surely this would diminish the significance of GHGs.
[...] it seems to me that by weighting the solar irradiance more strongly in the
models, then much of the 19th to mid 20th century warming can be explained from
the sun alone.
[...] we found the [urban warming] effect is pretty big in the areas we analyzed.
This is a little different from the result you obtained in 1990.
[...] We have published a few of papers on this topic in Chinese. Unfortunately,
when we sent our comments to the IPCC AR4, they were mostly rejected.
I thought I’d play around with some randomly generated time-series and see if I
could ‘reconstruct’ northern hemisphere temperatures.
[...] The reconstructions clearly show a ‘hockey-stick’ trend. I guess this is
precisely the phenomenon that Macintyre has been going on about.EnjoyMy work is as Director of the national centre for climate change research, a
job which requires me to translate my Christian belief about stewardship of
God’s planet into research and action.
