Unfortunately,
no validation of this temperature record has been given.

Also the importance
of (
temperature) measurement errors on the long term predictibility
of non linear time series (=
temperature records and proxies) seems to be key to me for an eventual
validation of any predicitve model.
One
of the key comments for me in M&W is — «On the other hand, limiting the
validation exercise to these two blocks is problematic because both blocks have very dramatic and obvious features: the
temperatures in the initial block are fairly constant and are the coldest in the instrumental
record whereas the
temperatures in the final block are rapidly increasing and are the warmest in the instrumental
record.
My recollection was that in another context, when confronted with the fact that climate models have not been successfully validated against
temperature records, or general global climate, Gavin responded that that type
of validation was not necessary.
