This sounds good. I'll do the refs and figures. If you get any more info on either of
these let me know. I'm keeping all the emails and I see a list at the end of those to
I'll expect a version from you on Jan 4. If you could send me your
current version as of
maybe last thing tomorrow your time then I can read that rather than what I sent out.
I realise that suggestions might come from the LAs over this time, but I don't think
we are going to get that many. Apart from Dave and David email traffic is quiet on IPCC
Maybe when you send that (tomorrow late your time) you can tell which bits are near
complete for
you and which you still plan to work on. Depends, I guess, on how much time you'll have
Dec 24-28. I know I will have very little over these dates - family here etc and trip to
the new baby again ! I'll be able to get back to it from Dec 29 onwards.
Thanks for the MSU update - I hope it resolves itself !

I have been working on the draft full time for over the past week. Some editing, some
trying to fill in missing pieces. Not sure we are quite together on everything, and you
will have opportunity to correct anything I do. The idea here is to edit. If you
disagree with something, rather than eliminating the old stuff and replacing it, the
idea is to change it to accommodate both views. I am not sure the current draft has
your views properly reflected on circulation changes. Some of what you wrote in 3.9.?
was at odds with 3.5 and 3.6, so if you want that in the conclusions you need to alter
3.5 and 3.6.
I can try to send you my signed off version on Jan 4. the 31st is a holiday here and
1-2 is the weekend. But I can also send you earlier versions: I am attaching the draft
I am working on now.
I do not plan to modify any figures, except you will see in this draft there is one new
figure (on the US drought) as a placeholder. I believe the figures sent by Jim
yesterday were not new, only the captions were changed. I need to check that.
I sent you yesterday a list of references that have been removed, and there is now one
more. I'd like it if you can be the keeper of the refs, and also the figures. Looks
like the ones from Dave will arrive later rather than sooner.
let me know if this doesn't work.

No idea how Chris Folland got this. Presumably David Parker forwarded it !
Anyway, it doesn't matter. The questions are:
When will you be sending me your signed-off draft?
Will this be the complete doc file of text?
Will you be modifying any of the figures?
On the latter just want to know if I'm keeping track of figs as well as Refs. I've got
the two you sent last night.
I'll be off from 5pm on Dec 23. I'll begin reading the draft from Dec 29. Will likely
be in at least once on Dec 29-31, but will be checking email from Dec 29.


As someone who dealt with these matters in the past, a decision about the climate
normals period was regarded as so important that all of WG1 debated it and agreed the
outcome. So that should be the route again, I believe, if a change is wanted. From a
personal perspective, I tend to agree with Phil that this time we should stick (in
general) to 1961-90 normals, and that IPCC 2013 should perhaps change to 1981-2010.

Having said that, we may produce 1981-2000 normals in the next year for SST if we can
solve adequately remaining problems (for climate change monitoring) with satellite SSTs.
A key goal is monitoring changes in the Southern Ocean. Solutions are likely to include
use of some corrected (to bulk SST data) ATSR data. This depends on work elsewhere in
the Met Office. However, some less well corrected AVHRR data is needed as well to extend
normals adequately back to 1981 in much of the Southern Ocean.This may give a new
perspectives on the southern ocean SST changes; are likely to be significantly different
in the southern half of the southern ocean from the global average. This is suggested by
the lack of reduction of Antarctic sea ice, in contrast to the Arctic, which still
persists. Such work may or may not get into IPCC FAR but if it did, it could be a
special case. But it would need careful handling for conversion to advice to policy
