What about the report from northern Alaska where the average temperatures
had risen 8C over the last forty years resulting in the thawing of the
permafrost. Apparently this 'permafrost' until now, had been frozen since
before the last ice-age.

They are having to move a whole town because the land is now eroding away.

I agree with all that's been said. I will also add that I didn't think
much
of the talk on Greenland's ice sheet. What they failed to mention, is
that
the interior temperatures of Greenland have been steadily falling. It's
only the coastal areas that are warming, likely due to changes in wind and
ocean circulation and possibly, nothing to do with global warming.
Several
other area's within the Arctic Circle have recorded less sea ice but
substantially more snow.

The other side of the coin is that the Hadley Centre don't just have one
single model. They have several, some of which show a very dramatic and
severe cooling of Western Europe, similar to that of the "Little Ice Age"
and that is based on a weakening of the Thermohaline Circulation and a
freshening of the seas in the North Atlantic region. A measurable
reduction
has already been detected within the THC and therefore, one has to
conclude
that: A. This trend will continue and B. At some point in the next 20 - 50
years, this country will experience much colder winters, irrespective of
what happens in the rest of the world!

Norman. I was watching this morning the BBC breakfast news coverage of
the
global warming topic. Their news man Bill Turnbull was talking live
from
Kew gardens and then supposedly linked to a colleague in the Maldives.
The
whole tone of his report was "when sea levels rise" "in fifty years from
now
the sea would be over my head" and so on. In fact there wasn't one piece
of
objective evidence that the sea had risen at all. As far as I can
ascertain
sea levels for that area in the Indian Ocean have shown no appreciable
rise
in twenty years. I am prepared to be contradicted though. Back to the
news
item, I was expecting the journalist to be showing evidence of how far
the
sea level had risen but there was nothing but this bold statement that
it
will rise by as much as aprrox 6ft in fifty years!

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 :-(
