# Re: [Phys-L] [Phys-l] Poll shows fewer Americans "believe" in global warming

Suppose there are 200 million cars in the US which account for all the man made CO2 increase in the atmosphere.
Suppose a tail pipe is 2 inch diameter, and emits 20% CO2 when the engine is running, which happens on average 2% of the time. To counter that effect, let's estimate the magnitude of the flux of a gas which is 1000 times more potent at cancelling the global heating effect than CO2 is at exciting the effect.

We will suppose that the palliative flux is emitted 100 times faster than an exhaust flow. What diameter of pipe should we visualize?
sqrt(2E8 cars X PI sq inches tail pipe area X 0.02 duty rate X 0.2 CO2 fraction X 0.001 potency factor X 0.01 flow ratio X 4/PI pipe diam to area ratio )- this provides me a back of the envelope estimate of 6 inches diameter for the quenching gas exit pipe diameter. This is certain to be an underestimate. This is described as a garden hose?

Brian are you claiming it's a ghost because it'd take much more than a garden hose or do you think the theory is very wet?

Remember the year w/o a summer?

bc thinks a poor temporary solution.

p.s. don't remember it in the book "... an anthology of partly-baked ideas".

I heard from the author of a popular treatise, whose name I caught
(phonetically)
as something like "Super Freeconomics".
He aired a suggestion which as far as I know is already discredited, for a
quick fix on Global Climate Change: Sulfur Dioxide.
He asserted that this gas is much more potent than CO2 [like numerous
other gases...]
The argument goes like this:
" say that Global Warming is real, and we URGENTLY need to do something.
How much Sulfur Dioxide [the component of volcanoes which is known to have
caused episodic climate cooling] would it take to stop the warming trend?"
Not much. One single polar garden hose from a generator would provide
sufficient flux,
he says.

If you are looking wistfully for a DeusXm., this is it! He says that if
