The week of 6th to 10th September would be good (Keith will probably be able to see you too during that week, so I've cc'd this to him).  Just pick a day.

I think that capture the 1910-1930 warming trend, but then fail to capture the warming from 1960 to the mid 1990s - because of this non-temperature effect that we can see but cannot explain.  We can talk some more in September about this.
