Dear Mike,

Thanks for your detailed reply concerning Scengen and CC:Train. I was not
proposing to incorporate Scengen in a major way into the training package,
and I am quite aware of the problems of consistency regarding aerosol
effects, natural variability, etc. Rather, I thought that the training
package would be an excellent way to introduce the existence of Scengen
(and MAGICC) to the Country Teams which are responsible for coordinating
national assessments. (the intention was NOT to provide intensive
technical training in its use -- the country team members are largely
coordinators, not technical climate experts). In this way, when it comes
time to actually carry out the national assessments, Scengen would be
recognised as a major tool for scenario generation and, if appropriate, CRU
could be contacted regarding its application, technical training or
collaboration. You had mentioned to me at the IPCC meeting in London that
one of your major aims was to get Scengen recognised as the "standard" for
scenario generation for impact assessments, and I simply thought I saw a
way of furthering that aim through the CC:Train mechanism.

Given the training programmes that you are currently proposing through
ENRICH and others, I can understand your fears that we might "muddy the
waters". Let me pose the following options; that we

(1) use some hard-copy examples from Scengen;
(2) incorporate a demonstration diskette (do you have one?);
(3) just mention the existence of Scengen;
(4) not mention Scengen at all.

Frankly, I am quite happy with any of these. The part on climate change
scenarios is really only a small bit of the overall V&A training package in
any case.

Good luck with your proposals.

Cheers,
Dick

Dick,

And Happy New Year to you also.

You've posed me a tricky one re. SCENGEN and my answer about it being
incorporated into the CC:Train package as a component tool is going to have
to be 'no'. Let me explain.

We too here have plans to exploit SCENGEN (and MAGICC) in a
training/educational context. I ran a pilot seminar here for UNEP before
Christmas on scenario construction, although this was using the new
WINDOWS/Unix versions of both MAGICC and SCENGEN (MAGICC 2 and SCENGEN 2;
IPCC 1995 compatible) we have re-written. Also, I have just submitted a
proposal (called SPARCCS) to ENRICH in DGXII for a support package for
regional climate change scenarios. This would be a 2-year project with
emissions people, as well as MAGICC, SCENGEN and our new global historic
climatology. I think we have a good chance of funding.

With this background I do not want SCENGEN (and especially the old DOS
version) 'leaking' out into the climate training community at this stage.

I am confirmed in this view by thinking that the complex issues surrounding
scenario creation (and the new IPCC Taskgroup on scenarios for the 3rd
assessment is grappling with these - ask Tim Carter about it) should _not_
be an essential part of a vulnerability/adaptation package. And even if
you
think differently then let me suggest the following: if you think it should
be a minor part then I do not think that you need SCENGEN formally
incorporated; if you think it should be a major part then not only do I
think you are wrong in thinking so, but there is more to the scenario issue
than can be supplied by SCENGEN - for example, you need MAGICC, you need to
consider how you handle aerosols, and you need to think about natural
variability and signal/noise issues.

My feeling is that by all means use SCENGEN within CEARS in thinking about
the training package and coming up with some off-line examples (either
sample scenarios or guided sensitivity), but do _not_ incorporate it in the
package. [By the way SCENGEN does not have imaginery countries!]. If
people want more detailed thinking on scenarios then you could always refer
them to CRU (which is what our speciality is).

I hope you understand my feelings on this - I am not trying to be negative,
but am thinking ahead and about the complexity of the scenario issue. I
have talked with Tim Carter recently at some length about some of these
things so I will copy this correspondence to him.

Good luck with CC:Train anyway and I'm sure you'll come up with something
good.

Regards,

Mike
