Along with the links, I will also send out a set of
questions to focus your reading of the articles. As
part of your pre-work, you will be asked to submit a
short response to these questions (no more than a
page of double-spaced text) at the beginning of class.

At the end of class, one student will be assigned to
write a short summary of the articles and conclusions
drawn during our discussion.  I’ll review the summary
and post it to the class blog so that everyone can
benefit from the effort.

Highly-variable NH temperatures? Moberg et al., 2005
“ Indeed, the challenge for palaeoclimate researchers —
  and their funding agencies — is to produce multi-proxy
  reconstructions at the appropriate regional scale so that
  all of the voices can be heard.”
  David Anderson and Connie Woodhouse
“High-resolution” proxies Moberg et al., 2005

Climate sensitivity
In IPCC reports, climate sensitivity refers to the change in
the mean global temperature following a doubling of the
concentration of CO2 in the atmosphere.
Workload
