I agree greenheart his credentials look fine and in as far as this one aspect of the IPCC modelling claims go he is reasonably right ,what he is talking about is considered to be a fairly natural level of activity tho disputed in its causes.
One very good thing about this debate that I am happy with is the effort being made to understand our world better , to do that needs intense scrutiny of ALL matters ,it would be very bad to put fear in future generations for no good reason.
There is enough bull in the world without adding to it.
Anyway hope you and yours have a good Xmas,all the best.
