Unformatted text preview: o Does the parallel nature of the increase in concentration of the CO 2 and temperatures prove that CO 2 is the cause of this warming trend? o Keep in mind that compared to the age of the earth, a 120 year period is short-term and you need to be careful about interpreting these short term effects o What is it about a molecule that makes it a greenhouse gas? • Wavenumbersds vs Wavelengths o Wavelength (um) = 10,000/wavenumber...
