Todd: Can't increase CO2 past 5%... bad for breathing.... biologists
say that plant growth increases at 1.5% CO2... this is probably a
feedback mechanism

Broughton: You looking for a better experiment to back up your
position? Wesley's isn't convincing me. You're not gonna let him speak
for you right?

Bob, you started off with this "I don't think you can show an
experiment that will show that CO2 cause heat to be retained."

This has been demonstrated.  I can and did show you such an
experiment.  And you could have found one yourself if you had bothered
to google for it.

In short, your thought experiment has been shown to be wrong by an
actual experiment.

Here's one experiment done by a fifth grader.

The link to the chart leads to a 404 error.  You can still see the

Well Tony, I don't see where your experiment demonstrates that CO2
causes heat to be retained. This is the criterion specified by
Broughton. If they had turned out the lights and the temperature didnt
fall to the initial temperature, the claim would be proven. I mean,
the atmosphere heats and cools every 12 hours right? CO2 has a higher
specific heat than O2 or N2, but if it heated up 20 degrees in the
day, but only cooled off 19 degrees at night, it would be hotter than
heck after a few weeks, but we arent seeing that are we? Broughton
says CO2 causes heat to be retained. I dont believe it till I see it
or its so obvious I have to believe it.
