Ever growing? I would be surprised by that, as it seems to me - as a
reluctant convert to AGW some ten years ago - that the evidence is
becoming more compelling all the time.

I offer you this article on historical warm periods from the past. It
is worth a read, and I will offer it to my students without comment,
just to maintain a balanced view as ever!

I think the point is that, if you accept that increased and still
increasing CO2 is the main cause of the current warming, then it will
almost certainly go on indefinitely into the future, and probably at an
accelerating pace. In 50 years time it will have far outstripped 1000
(and 2000) years ago, even if it has not yet quite done so.
