Thus, if adding carbon dioxide reduces the ability of the earth system to cool by emitting thermal radiation to space, the positive feedbacks will further reduce this ability.

More greenhouse gases in the atmosphere impede the escape of thermal infrared radiation to space, and thereby raise temperature.
Bigelow Aerospace, an American space technology company, has already developed habitat modules, or expandable habitats (the Bigelow Expandable Activity Module, or BEAM), which are able to provide radiation and thermal protection and serve as a facility in which astronauts can operate in space.
Scientists at The Australian National University (ANU) have designed a new nano material that can reflect or transmit light on demand with temperature control, opening the door to technology that protects astronauts in space from harmful radiation (Advanced Functional Materials, «Reversible Thermal Tuning of All - Dielectric Metasurfaces»).
Absorption of thermal radiation cools the thermal spectra of the earth as seen from space, radiation emitted by de-excitation is what results in the further warming of the surface, and the surface continues to warm until the rate at which energy is radiated from the earth's climate system (given the increased opacity of the atmosphere to longwave radiation) is equal to the rate at which energy enters it.
More greenhouse gases in the atmosphere impede the escape of thermal infrared radiation to space, and thereby raise temperature.
I think the central point is that of the scale of energy imbalance and the timescale for response: our addition of CO2 reduces outgoing thermal radiation, so incoming energy from the sun is greater than outgoing energy to space.
Greenhouse gases absorb thermal radiation from the surface and slow radiative loss to space.
Why is this so much warmer than the 255 K effective temperature of the thermal radiation emitted to space?
How can the earth be radiating a crude BB type spectrum corresponding to the surface Temperature when Trenberth claims that only 40 W / m ^ 2 escapes to space in the atmospheric window, and folks insist that the main body of the atmosphere (gases) does not emit thermal radiation.
The difference between the solar radiation absorbed and the thermal radiation emitted to space determines Earth's radiation budget.
Once energy from CO2 and H2O begins to leak into outer space, LTE is violated, temperatures * must * fall until a more global thermal equilibrium is established with incoming thermal radiation and convection.
If CO2 and H2O molecules now are cooled below the previous equilibrium point by having their radiation allowed to escape to outer space, then I believe these molecules must then tend to absorb more energy than yield energy with each interaction with the other components of the atmosphere until that atmosphere as a whole reaches a new thermal equilibrium where the net radiation going out and the net radiation coming in (primarily from the sun and the surrounding atmosphere) is the same.
Each higher and cooler layer in turn emits thermal radiation corresponding to its temperature; and much of that also escapes directly to space around the absorption bands of the higher atmosphere layers; and so on; so that the total LWIR emission from the earth should then be a composite of roughly BB spectra but with source temepratures ranging ove the entire surface Temeprature range, as well as the range of atmospheric emitting Temperatures.
Any emission to the surface will not be absorbed and converted to thermal energy (because it comes from a cooler source) and so all radiation from the atmosphere eventually ends up going to space.
LR is the lapse rate (the vertical thermal gradient), and AARTS is the average altitude of radiation to space.
I initially pointed out that satellite makers do thermal testing of the satellites in a vacuum chamber whose walls are cooled by liquid nitrogen to simulate the heat - transfer conditions of space: no conductive / convective transfer, and virtually no ambient thermal radiation.
An aside: one of the reasons that clouds modulate temperature so effectively is not just the albedo increase which bounces downwelling short wave radiation back into space, but because they radiate IR back to the surface thus reducing the net rate of thermal radiative loss.»
An aside: one of the reasons that clouds modulate temperature so effectively is not just the albedo increase which bounces dowelling short wave radiation back into space, but because they radiate IR back to the surface thus reducing the net rate of thermal radiative loss.
The annular space between the inner and outer walls is evacuated, thus heat transferred is almost entirely due to thermal radiation.
For a stable climate, the sunlight absorbed by the planet must be balanced by thermal infra - red radiation emitted to space.»
Likewise, greenhouse gases work by reducing the rate at which thermal radiation is emitted to space.
Positive radiative forcing occurs when the Earth absorbs more energy from solar radiation than it emits as thermal radiation back to space.
The effect of this disparity is that thermal radiation escaping to space comes mostly from the cold upper atmosphere, while the surface is maintained at a substantially warmer temperature.
42, Steve Fish: The illustration clearly shows that thermals and evapotranspiration account for a total of 97 watts per square meter delivered to the atmosphere for re-radiation to space, while total radiation to space is 341 watts per square meter.
I believe that if in the vacuum of space you place a blackbody object with (a) a constant (i.e., unchanging energy per unit time) internal thermal energy source, and (b) internal / surface thermal conduction properties such that independent of how energy enters the blackbody, the surface temperature of the blackbody is everywhere the same and you place that object in cold space (no background thermal radiation of any kind), eventually the object will come to a steady state condition — i.e., the object will eventually radiate energy to space at a rate equal to the rate of energy produced by the internal energy source.
