Both, however, are efficient at intercepting outgoing infrared radiation from the Earth's surface and atmosphere The disparity is due to the different wavelengths of incoming solar energy and
outgoing infrared energy.
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 TO SPACE.
You might say energy is retained, but it is the vastly more numerous O2 and N2 molecules that are warmed and retain the heat, even though they can not directly absorb
outgoing infrared energy themselves.
Not exact matches
Because the climate system derives virtually all its
energy from the Sun, zero balance implies that, globally, the amount of incoming solar radiation on average must be equal to the sum of the
outgoing reflected solar radiation and the
outgoing thermal
infrared radiation emitted by the climate system.
He was right that surface temperature is determined by the balance between incoming solar
energy and
outgoing infrared radiation, and that the balance that matters is the radiation budget at the top of the atmosphere.
Because ozone acquires
infrared energy from
outgoing radiation from the Earth itself that mid latitude air is warm and is further warmed, or at least tends to be maintained in its warmer condition as it approaches the pole.
the short - wave, visible, part of the spectrum... balanced by
outgoing...... long - wave invisible
infrared energy..».
The excess gases in the atmosphere are believed to enhance the greenhouse effect by not only preventing
infrared light from escaping into space, but also by absorbing more
outgoing energy, leading to warmer surface temperatures.
Greenhouse gases don't block all
outgoing radiant
energy — it merely slows it down by capturing more
infrared photons and re-emitting in all directions including down — increasing net
energy retained at any instant in the atmosphere.
