Or 24 hour news coverage is getting better at pushing the agenda at us.

I would agree with you there Clive. News coverage always over-reacts,
sometimes it's to make up for being late on the scene but to be frank
often they treat a vague possiblilty as if it were earth shattering
news. We've seen many scientific theories trumpeted by the papers and
subsequently demolished by better evidence.

This is not the case with Gw. It may have been uncertain a few years
ago, but whilst we've argued over the evidence the figures themselves
have increased, new ideas been included, and even the exceptions people
used to say "yes but" about have been included in the models. The models
themselves have been tested by checking with the real present day numbers.
And the answers come out even worse now. Though I'm not a scientist I
feel there is now very little doubt.

Would you turn to the media first to tell you the causes behind the causes
of derailments or broken rails ? Treat the media and Al "politician"
Gore with the scepticism they deserve if you wish, but don't assume there
is no evidence behind them. You might find New Scientist a better primer
than News International
