A model black hole that traps sound instead of light has been caught emitting quantum particles - it could be the first time theoretical Hawking radiation has been seen
Crucially, since the artificial horizon can only trap photons in a certain range of wavelengths, it can only emit Hawking radiation in that range.
That's because once the sunlight hits an object, it heats up and emits infrared radiation — a form of radiant heat that gets trapped in your home.
July 17, 2013 at 1:39 pm The lapse rate feedback is only a negative feedback (in the general circulation model) if the long wave radiation that is released when the water vapour condenses is emitted to space rather than trapped by increased water vapour.
Infrared radiation emitted by the earth's surface is not trapped.
Tom Vonk is correct when he says that the following statements are over-simplifications and need corrections (in caps): «CO2 absorbs AND EMITS the outgoing infrared energy and warms the atmosphere TO A HIGHER TEMPERATURE THAN IT WOULD HAVE WITHOUT CO2» — or — «CO2 traps part of the infrared radiation between ground and the upper part of the atmosphere» AND IS THE MAJOR SOURCE OF INFRARED RADIATION FROM THE UPPER ATMOSPHERE radiation between ground and the upper part of the atmosphere» AND IS THE MAJOR SOURCE OF INFRARED RADIATION FROM THE UPPER ATMOSPHERE RADIATION FROM THE UPPER ATMOSPHERE TO SPACE.
The 1st is the usual «backradiation» one and the 2nd is because the atmosphere traps and reduces outgoing radiation transmission then the surface temperature must increase to emit more radiation to compensate.
Is this point only about the radiative characteristics of the H2O vapour, and the assumption that relative and / or specific humidity should rise thanks to CO2 - induced increased evaporation, which in turn would increase downwelling heat radiation — or just the part that slightly hotter surface (due to CO2) also emits more heat to be trapped by the vater vapour?
However, clouds also trap longwave radiation emitted by the Earth, as does water vapor.
Greenhouse gases allow much of the Sun's shortwave radiation to pass through them but absorb or trap the longwave, infrared radiation emitted by the Earth's surface.
Greenhouse effect - Heat - trapping gases (greenhouse gases) effectively absorb thermal infrared radiation, emitted by the Earth's surface, by the atmosphere itself due to the same gases, and by clouds.
In the troposphere, CO2 is optically thick and traps infrared radiation emitted by the Earth's surface.
