Wow 387 parts per million! That actually is around twenty times lower than has occurred in that not that distant past, at the time of the immediately previous Ice Age.
What! Twenty times! Is that a transient spike, after some "big release?"
....I should go look; but first let me just say:
Ric, Ric, Ric....
You are crossing the line from being a climate-science denier into being simply a science denier.
It was observations about carbon dioxide's "greenhouse effect" that led into the science of spectroscopy, and also evolving models of the atom that could explain spectroscopic observations.
You are questioning work done back in the 19th century by names such as Fourier, Angstrom, and Roentgen.
For a brief history, with modern updates, google Arrhenius & carbonic acid; or see:
http://www.aip.org/history/climate/co2.htmThat's the American Institute of Physics, isn't it?I think this link will answer your request for an experiment on CO2.
http://earthobservatory.nasa.gov/Library/Giants/Tyndall/Note the strong CO2 absorbance (dip) between 4-5 microns (where water does NOT absorb much). ...hence the logic problems arising as some simply say 'water vapor is a stronger GHG than CO2.'
