either,

How much do *YOU* know about AGW or like most ppl have you simply
accepted the much-publicised alleged received wisdom promoted by the
Global Warmingists ?

Did you know that the Greenland Ice cap has actually been *growing* ?
That the melting of the Greenland glaciers has recently *reduced* ?

It strikes me that the alleged yet non-existent consensus about AGW
has more in common with a slick advertising campaign than science.

I've been following the debates about global warming and the ozone
layer for many years now - some of the participants were cited in my
Ph.D. thesis back in 1969 - and I certainly know more about than you
do.

The reason that there is more snow falling on the top of the Greenland
ice-cap is simple enough - the vapour pressure of water increases with
temperature, so there is now more water vapour the in the air flowing
over Greenland. The Greenland glaciers don't melt, but rather slide
down into the sea, and that does proceed in fits and starts.

If you think that the consensus about global warming is artificial,
you clearly don't know much about the subject.

The problem with the consensus about global warming is that it asserts
that the cause is primarily human emissions and that reduction of human
emissions is the cure. Both assertions are incorrect.

Ok take a nice little rock, 3rd from the sun, say with no people on
it.
Now start pumping 6Gtons of extra CO2, a year, into the atmosphere,
for 50 years.
Will it have any effect on the climate?
Yes or No?



No. The amount of CO2 in the atmosphere is about 0.04% and has been for
the last 50 years or more. The proportion of that 0.04% contributed by
human emissions is very small. The big source/sink of CO2 is the sea. The
temperature of the sea controlls the amount of CO2 in the atmosphere.
Human emissions are insignificant.

That is not what I asked :)

Yes it is. I gave you the answer - No - then added some explanation.
