While on the subject of awkward, unanswered emails, let me pass on a message I recently sent to Dr James Hansen, the scientist widely famed as the “father” of global warming. I still hope he will offer some explanation.

Dear Dr Hansen,
The Climate Conversation Group and I have become interested in the very meaning of “taking the temperature”, calculating the so-called “average” temperature for a place and a region and the meaning of doing so. I have just seen your web page [The Elusive Absolute Surface Air Temperature (SAT)], discussing these and related matters. It is an interesting and informative page.
You say there is no agreed method of measuring surface air temperatures and, in fact, there are numerous practical and theoretical obstacles to ever achieving such a measurement.
There is a very obvious question raised by that discussion. We are interested to know why, if it cannot be done, do you do it?
Regards,
Richard Treadgold
