I am not very keen on this either Norman. It seems like a good old fashioned
bit of BBC bias in favour of the greenhouse effect climate change brigade.
They all conveniently forget that in the early middle ages there was a
spell of warming much greater than we have today. There was no
industrialisation around then. However, they all ignore that side of the
argument deliberately.

News24 have been running a lot of programming on climate change today.
I've only seen some snippets but I haven't been very impressed by some
of what the "experts" have been saying. For example, one of this
country's leading scientists in the subject has just said that the
amount of greenhouse gases in the atmosphere has increased by 40 percent
since the industrial revolution. I have no idea what the true figure is
but, bearing in mind that the main greenhouse gas by volume is water
vapour, that figure of a 40 percent increase must surely be wrong. He
was probably referring to gases other than water vapour but that's not
what he said and it does make a big difference.

My main gripe is that most of the "experts" are being very positive
about what "will" happen, even down to quite precise regional detail.
There's not a lot of uncertainty being expressed. The theme seems to be
that "our models show that this will happen and we are confident that
our models are accurate". If only it were that simple :-(
