Hi all

This a draft of our solar and volcanic sections, so you can see where we
have got to and what we intend to cover - note it is still some way off
being complete!

There is also a section at the start on land-use changes prior to 1750 that
Richard Betts, one of our LAs wanted the Paleo chapter to consider

Note also the brief sections on the climate response to solar and volcanic
forcings, these may also fit better elsewhere


Cheers
Piers

Hi Ram and Piers - might be good to share, and
also to share w/ David Rind, Keith Briffa and
Gabi, since we need to make sure all our chapters
are compatible on the issue of solar. I believe,
last we talked, that you were playing pre-20th
century aspects.

I think David tries hard to keep in touch w/
Judith L on these issues too. That should help.

We're happy to share our text w/ you too.

Thanks again, peck
