Who knows?

The problem with science is there are arguments and counter arguments.
We are warming up, something ten years ago I would have dismissed, the
consequences of such changes is the problem. As far as the programme
was concerned I was sceptical as to it being the cause of the
sub-sahara drought, to many other factors comeinto play that
interrelate and I still don't think we know all the equasions yet.

I would have been far more convinced of the theory that this was the
cause of the 70's/80's droughts in the Sahel had they provided evidence
of lower SST's in the areas of ocean that had supposedly had prevented
the African monsoon from moving northwards.

Well there is always this :-)
