The song was heard in Disney's Phineas and Ferb: The Best LIVE Tour Ever!, and also was used in the Phineas and Ferb's Rockin' Rollin' Dance Party show at Disney California Adventure. S.I.M.P. (Squirrels In My Pants) is also one of the eight songs that was re-released in the Phineas and Ferb Karaoke Soundtrack.
The atmosphere is heated chiefly by radiation from Earth's surface rather than by direct solar radiation because about 50 percent of the solar energy is absorbed at Earth's surface. 30 percent is reflected back to space.
Part of this radiation is directed towards the surface, warming it. On Earth, solar radiation at the frequencies of visible light largely passes through the atmosphere to warm the planetary surface. The surface itself emits energy at the lower frequencies of infrared thermal radiation. Infrared radiation is absorbed by greenhouse gases in the atmosphere. These gases also radiate energy, some of which is directed to the surface and lower atmosphere.
