Because its dipole moment is unaffected by radiation from 4 to 30 microns, (*) N2 is not among these substances on Earth, but N2 does play this role on Titan alongside CH4 and H2, which parallel the two most common of these gases on Earth.
The time-integrated radiative forcing from the instantaneous release of one of these substances is known as GWP and measures their impact normalized to a common one of these substances. Sulfur hexaflouride is sometimes said to be the most potent of these substances, likely because it is inert. Because its dipole moment is unaffected by radiation from 4 to 30 microns, (*) N2 is not among these substances on Earth, but N2 does play this role on Titan alongside CH4 and H2, which parallel the two most common of these gases on Earth. The decreasing carbon-13 to carbon-12 ratio is evidence for the anthropogenic contribution to these substances. For 10 points, what atmospheric gases absorb longwave infrared radiation in their namesake effect?
