Yet, through differences in its formation and evolution Venus has become a world with a surface and atmosphere astonishingly different from Earth: entirely devoid of water, lacking plate tectonics and its ability to bury CO2 and stabilize its, Venus's thick CO2 atmosphere traps the incoming solar radiation and heats up to about 740 K (464 C).

This radiation, plus inevitably powerful stellar winds, would likely blow any atmosphere away from our hypothetical burgeoning Earth 2.0.

Surface radiative energy budget plays an important role in the Arctic, which is covered by snow and ice: when the balance is positive, more solar radiation from the Sun and the Earth's atmosphere arrives on the Earth's surface than is emitted from it.

14 C is produced by thermal neutrons from cosmic radiation in the upper atmosphere, and is transported down to earth to be absorbed by living biological material.

Thus the radiation entering the atmosphere from the surface of the Earth is not equal to that radiatied by the air to the surface.

They don't have to be scientists to understand that the higher energy waves of visible light from the Sun can penetrate through CO2, H2O, CH4, NOZ etal in the atmosphere, but the lower energy radiation of infra - red waves, from Earth's surface, have problems getting back out through these molecules, and a new energy balance has to be established in the form of rising temperature.

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.

The fact that there is a natural greenhouse effect (that the atmosphere restricts the passage of long wave (LW) radiation from the Earth's surface to space) is easily deducible from i) the mean temperature of the surface (around 15ºC) and ii) knowing that the planet is roughly in radiative equilibrium.

CO2 reduces the rate at which the atmosphere loses its energy to space via infrared radiation, which in turn reduces the flow of energy from the Earth's surface to the atmosphere.

I have seen a statement that the outer edge of the earth's atmosphere receives approximately 14,000 x as much energy in solar radiation as we currently generate from fossil fuels.

What the CO2 (both «cold, hot and warm CO2 ′) and other gasses do is to make the atmosphere more optically thick to thermal IR radiation emitted (mainly) from the Earth's surface [note2] which has consequences for the equilibrium temperature profile of the atmosphere.

Although that will be true in the mid atmosphere, do you agree that is not the case near the surface of the Earth where the greenhouse molecules are being excited by blackbody radiation from the Earth's surface, but are being relaxed by collisions with other air molecules such as N2 & O2?

Do you think you the results from your experiments would allow you to accurately predict how a doubling CO2 will interact with thermal radiation in the earth's atmosphere?

Much of our knowledge about the atmosphere is obtained from observing the radiation it emits, using satellites that orbit the earth in space.

This is about the radiation from the Earth to space, which is prevented by the atmosphere's greenhouse gases, and as we pour more and more greenhouse gases into the atmosphere, less energy will be sent into space.

The spectrum of thermal infrared radiation is practically distinct from that of shortwave or solar radiation because of the difference in temperature between the Sun and the Earth - atmosphere system.

Total solar irradiance - The amount of solar radiation received outside the Earth's atmosphere on a surface normal to the incident radiation, and at the Earth's mean distance from the Sun.

Now only about 6 % of Earth's radiation to space is directly from the surface; the remaining 94 % is from every point of the atmosphere visible from space (so nothing from below clouds).

Traditional anthropogenic theory of currently observed global warming states that release of carbon dioxide into atmosphere (partially as a result of utilization of fossil fuels) leads to an increase in atmospheric temperature because the molecules of CO2 (and other greenhouse gases) absorb the infrared radiation from the Earth's surface.
