Hi Phil
I am about to depart on 3 consecutive weeks of trips: to AGU next week, then to Crete for a
hurricane mtg the following week, and then to Washington DC for a ocean obs mtg. Meanwhile
I have been finishing off an article for Scientific American on hurricanes and global
warming. It is very trying and they insist on putting in their own figures and ignoring
the ones I sent and my suggestions. I have had some influence but not enough. Suspect
this will lead to criticism. Comes out about June 22 in July issue.
I also was invited to respond to Nature for a new blog they have launched:
We have launched the blog at [1]http://blogs.nature.com/climatefeedback and would very much
welcome your input.
So you will see one there that I posted.
The New Scientist link looks useful.
Cheers
Kevin

Kevin,
Been meaning to email you! Good that this error in Fig 3.18 was spotted and
caught in time.
Thanks for the ppt a few weeks ago. I've used them (well the earlier
ones from Paris) in at least 4 talks - the Royal Society in London,
the French Academy, in Seoul and at a local sugar beet research
station and at a meeting in Spain last week. Good also that now
I can now leave a copy - basically about 20 slides that constitute 30
minutes' talk. Only done this for the last talk as the others
were before the end of April.
This link is good if you've not seen it.

Helps to counter some of the awful papers that seem to be appearing
(by Carter in some Australian metallurgical magazine and David
Bellamy - in the Proc. Inst. Civil Engineers in the UK). I won't
bother emailing these unless you really want to read this
rubbish.
Cheers
Phil

I am attaching a corrected version of the figure. You can see the reason
it was changed was to alter the units from K/decade to degrees C per
decade but unfortunately the label was altered also.
