I liked what Joe said.

"Do you believe that the contribution from human beings which is equivalent
to the width of a hair on a one kilometer bridge a year, of a trace gas
essential for the maintenance of life on the planet, is worth more to the
global temperature then the influence of the sun, the ocean and volcanic
activity?"

Very minor variations of this 'trace gas' compared to itself
rather than it's overall composition of the atmosphere can
lead to dramatic differences in temperature. If there were none
of this gas in the atmosphere at all, the temperature would be
far below freezing. Just a few hundred ppm and we can sustain life.

You lost a syllable from the subject line.

In line with almost all climate scientists and physicists, over the
last 100 (ish) years and especially recently; very probably yes.

Stewart's observation is almost certainly correct.

It seems to be that, if you take Joe's words literally, the answers
would be no, yes and yes. One would hope that by the influence of the
sun he intended decadal to millenial scale variations in solar output,
but the literal influence of the sun adds about 280K to the earth's
temperature.

A lot less than that I would have thought. We can use the moon
as a good control and there the average temperature is about
200K. Ok, not a lot but a good bit less.

If he's not worried about the effects of traces of a gas, how about he goes
into a chamber with a similar trace of hydrogen cyanide in the air to prove
his point?

The HCN levels in a smoke-filled hostelry a few years ago must have been
measurable.

If the levels had been the same as CO2 in the atmosphere, everyone would
have been dead in ten minutes.
