Hi Phil.

Thanks - I hadn't spotted this. It's impressively mad.
Steve McIntyre's clearly putting a lot of effort into these posts - but
he's badly let down by the people adding their comments. I don't think
many of them have actually read the papers.

At one point I was going to download the GHCN station data, feed it
through the same processing steps we used on your station records, and
make an equivalent to CRUTEM3. It would be interesting to look at the
differences in detail. However, on reflection this might not be a good
idea - we don't want the two datasets to get too incestuous.
