On the other hand, I am interested in the *facts* of this matter. If you care to dispute anything factual in my pages, I will be happy to correct any errors, or to make reference to any important papers that I have omitted. You have not disputed any facts so far.

What you call the dip is prefectly compatible with the GH hypothesis, of course.

While we're on the subject, do you regard your Nature '74 paper as predicting another ice age soon? I mean, unequivocally predicting the same? It uses phrases like "to make fig X come true..." and I'm not quite sure whether that is intended to be predicative or not.

If there was anything to the 70s scare, then it would have made its way into the journals. But it didn't.
I accept (its on the web page) that some scientists were concerned about a possible iceage. But oddly, none of that concern got into the journals. In a sense, it could be seen (I see it) as an example of science working well: over enthusiastic thoughts never made it past peer review.

I must say I didn't read the details but the little I did read didn't incline me to read more.
