I've been challenging the Warmers to show us a laboratory experiment demonstrating the effect of a 200PPM increase in CO2 on temperature and so far have rung lemons.

Let's take 2 10 gallon fish tanks side by side. In the first is air. In the second we add 200PPM CO2.

Here's the problem, 200PPM is less than a whiff, it's a barely perceptible increase, so how can I make sure I only add 200 PPM? (See, when the Warmers do this experiment they often put in 200,000 - 600,000 PPM but we're only going to add 200PPM.)

Let's see -- how many ounces in 10 gallons? There are 128 fluid ounces to a gallon so there are 1280 total fluid ounces in a 10-gallon tank. We want to add 200 PPM, which is .02% (I said it was a tiny number) so therefore we add about 1/4 ounce of CO2, but that's liquid...how do I adjust for the gaseous state of air?

Can I just drop in 1/4 oz of dry ice or is that too much by volume?

I have been trying to find an easy way to turn lead into gold...

Does anyone have any hints?

Here's a new experiment. What happens, if you remove 200 ppm? Do you think you could get back to us on that after the TG break, thanks?

I have been working on a perpetual motion machine. I figure if I build these birds to be 50ft tall and place them by the ocean, they will bob forever. This will solve our energy needs

So all of the Liberal scientists and there's not a single coherent answer. I'm so shocked. Old Rocks? Konrad? RW?

Here's the problem, to add 1/4 oz by volume puts far too much CO2 into the tank because it's a solid and not a gas. If we were to add 1/4 oz by volume, not weight, of neutron star we would also be putting far to many molecules in the tank.

We need to adjust for the difference in density between solid CO2 and the far fewer molecules needed to add 200PPM of CO2 to the gas (air) in the tank.

All you Warmers and Liberal Intellectual Elites knew that, right?

If you exhale one breath into the hi-CO2 tank, that should just about do it.

You lost me when you started talking about gallons. The atmosphere and carbon dioxide is are gases at 1 atmosphere and 32 degrees F. What do fluid ounces have to do with a gaseous state?

I'm trying to do a real experiment that can be repeated anywhere you have 2 10 gallon fish tanks. How much dry ice do you add to the second tank to get a 200 PPM increase?

Answer to what? You haven't posed a coherent question that I can see and your "experiment" doesn't make much sense. All you have to do is put two different concentrations of CO2 into a spectrophotometer and show that the higher absorbs more infra-red radiation. That may not be able to be done "anywhere", but at least it shows something! Unlike the fish tank experiment, where you don't even say how you're going to measure an increase. Here's a hint. That small a volume is unlikely to be able to absorb enough energy to provide you with a measurable increase in temp and are there unsatisfactory as a model for the atmosphere.

Yes I know how to do that.

Take about a pound of lead birdshot and put it into a sock.

Vigorously apply that lead birdshot sock to the cranium of a person with gold.

Hereabouts we call that the philosopher's sock.
