However the jury *is* still out with respect to the mechanisms behind
this, and there can be no proof either way until long after we have
all long been forgotten.

Steve,

You do understand that if you are correct, by the time it is proved
that it is caused by burning fossil fuels, then it will be too late to
do anything.

It is already too late to save the the Arctic sea ice, and in twenty
years time it will be too late to save the Greenland ice sheet (that
is if it is not already too late to save it.) That means a 7 metre (20
ft) sea level rise, enough to turn London into Venice, and Venice into
the lost city of Atlantis.

But Coventry will be safe :-)

Cheers, Alastair.
