Look across space from one edge of the visible universe to the other, and you'll see that the microwave background radiation filling the cosmos is at the same temperature everywhere.
Previously, all astronomy observations have relied on light — which includes X-rays, radio waves, and other types of electromagnetic radiation emanating from objects in space — or on very - high - energy particles called neutrinos and cosmic rays.
Carbon dioxide, as well as CH4 and other gases, absorb and re-emit longwave radiation back to the earth's surface that would otherwise radiate rapidly into outer space, thus warming the Earth.
Cosmic radiation, another form of energetic ions in space, is an important consideration in designing materials and advanced electronics used in satellites and other space exploration technologies.
Exposure to radiation (although considered minute), cramped spaces, and potential infections (from other passengers on the plane), and the stress of changing time zones (forcing your circadian hormone levels to adjust) can all add up to quite a stress, especially for frequent fliers.
Much of this radiation is returned to the space and the other part is absorbed by the layer of gas surrounding atmosphere causing the greenhouse effect.
What other things in the Earth system will change when it warms up that will affect how much SW radiation is reflected back into space [eg ice - albedo feedback, cloud changes] or affect what proportion of emitted LW radiation is allowed to escape to space [eg Water Vapour, cloud changes].
Theory certainly suggests that a warmer atmosphere as a result of higher CO2 concentrations will emit photons more frequently — and more of these will by chance find a path to space restoring the conditional equilibrium between ingoing and outgoing radiation — the condition being that all other things remain equal.
Any extra warmth generated in the atmosphere by CO2 or any other trace gas will quickly be neutralised by the hugely greater effect of the oceans in so far as it has not already been dispersed by increased radiation to space, evaporation, convection, condensation and rainfall.
Ultimately, only EM radiation can export energy out of the earth atmosphere to space (ignoring satellite launches, and other minor massive ejecta for the nit pickers).
But most of the infra - red radiation emitted by the earth's surface is absorbed in the atmosphere by water vapour, carbon dioxide, and other naturally occurring «greenhouse gases», making it difficult for the surface to radiate energy directly to space.
The atmosphere on the other hand can cool only by IR radiation to space.
In other words, no climate models, as of 2007, were accurate enough in their modeling of Earth's atmosphere to reflect, appropriately, how much solar radiation was reflected back into space and how much was trapped / absorbed.
The radiatively active gases (H2O, CO2) on the other hand are like the holes (or opened windows) on a greenhouse, enabling the atmosphere to cool by radiation to space.
Much of this IR is at wavelengths at which other atmospheric constituents do not interact, so if CO2 is exposed to a warmer surface like the earth, it will absorb radiation that would otherwise pass through into the cold of space AND likewise if CO2 is exposed to the cool of outer space it will emit vast quantities of IR at wavelengths which other gases can not emit.
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.
Heat conduction into space occurs through two mechanisms: mass interactions (i.e. through atoms and molecules and other particles) and radiation (i.e., light).
Until or unless the planetary body is at the same temperature as deep space there will always be energy input at the bottom of the atmospheric column (and a temperature gradient) and there will always be heat loss by radiation (or some other means like boiling off of the atmosphere) at the top of the column.
All absorbed radiation must be returned to space, except for very minor imbalances (e.g., of the order of currently estimated 0.9 W / ^ 2) during forcing by CO2, solar changes, aerosols, or other climate drivers.
Somehow, largely by conduction, convection and latent heat, and such means other than by radiation, heat flows from the earth's surface to somewhere, where it is then radiated into space.
«Radiative energy transport, on the other hand, depends only on the difference of the local matter and radiation temperatures at a single point in space.
In February, the National Academies of Science released two major reports on geoengineering, one on carbon dioxide removal technologies (to draw down carbon dioxide from the atmosphere and hence reduce the greenhouse effect) and the other on «albedo modification» or solar radiation management technologies (to reflect a fraction of sunlight back to space and thereby cool the planet).
About 30 percent of the radiation striking Earth's atmosphere is immediately reflected back out to space by clouds, ice, snow, sand and other reflective surfaces, according to NASA.
Latent heat obviously can not escape directly to space, it is first converted to simply heat by condensation and then to radiation (by collisional excitation of CO2 and other GHGs).
5) Thus the presence of water vapour and CO2 means that less energy is radiated into space from within their characteristic radiation bands so the temperature of the earth's surface has to increase in order for energy radiated at other wavelengths to increase to compensate.
That goes for GHGs as much as it does for other gases, which means that radiation will gain more free access to space above in close step with the decrease in opaque gas molecules.
