TO LINDA MEARNS AND MIKE HULME
FROM JOHN HOUGHTON
PLEASE SEE COMMENTS ON ZERO DRAFT OF CH 13


o The chapter presents useful and helpful background information and
assessment for those employing or wishing to employ climate scenarios.

o The chapter would be more readable if it were shorter and punchier
-many of the sentences are more complicated -or convoluted - than they
need be.

o Can there be more emphasis on climate extremes and how appropriate
scenarios for these can be provided? There is quite a bit on climate
variability but it is the extremes �how their intensity and frequency
might change - that provide the greatest impact.

o There is significant overlap with chapter 10 esp for instance in 13.4
which can probably be significantly shortened by reference to ch 10.

o The chapter contains a few examples. But it would be much more
interesting, readable and useful if there were more examples (say 2 well
chosen ones) of climate scenarios and their use.
