Hope everything is going fine at LDEO. Together with Keith
Briffa and other folks, we are collaborating in the elaboration of the new
IPPC Assessment. Keith is intensively working on the Northern Hemisphere
records and he asked me to compile all the available information on
temperature reconstructions in the Southern Hemisphere since the IPCC Third
Assessment in year 2001. The S.H. section should be very brief as regards
text, and possibly have a Figure incorporated as part of "Regional Changes"
or "The past 2000 years" sections. Please, find attached a file containing
a couple of paragraphs on temperature variations in the SH and a tentative
figure. As you will note, I incorporate the New Zealand temperature
reconstruction from the figure in your GRL paper. I do not have the actual
At this point, I kindly ask you to check the attached text to see if I am
missing some vital piece of information on the SH since IPCC third
Assessment. I would also appreciate a digital copy of the New Zealand
temperature reconstruction to properly be included in the Figure.
Keith also wants to know if you are willing to collaborate in the
incorporation of your beautiful work on the North American PDSI
reconstruction in the Assessment. Final decision on the material to be
included in the Assessment depends on the coordinators of the chapter
(Overpeck and Jansen) but we are trying to include as much information on
tree rings as we can.
Ed, thanks in advance for your help. Cheers,
