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.
It's a little denser than Earth, suggesting an iron core, and it's about the same size and receives a similar amount of radiation from its parent star as we do from the Sun.
Researchers say that if there were no VLF bubble, the radiation belt boundary would be far closer to Earth than it is.
However, the telescope will explore a much larger region of the sky than Kepler, with an emphasis on detecting rocky planets on Earth - like orbits that receive a similar amount of radiation as our own planet (the so - called habitable zone).
With the current GHG content in the atmosphere, more solar energy arrives than leaves via radiation -LRB-.85 + / -.15 Watt / m ^ 2), which raises the heat content of the terrestrial system, i.e., the average temperature over the whole earth + oceans + atmosphere.
Thus when the Earth is radiating with a greater intensity than the back radiation from the air, then the excess radiation will be absorbed by the air molecules, and the air will warm.
The whole issue is that any level above what is often called the «effective radiating level» (say, at ~ 255 K on Earth) should start to cool as atmospheric CO2 increases, since the layers above this height are being shielded more strongly from upwelling radiation... except not quite, because convection distributes heating higher than this level, the stratosphere marks the point where convection gives out and there is high static stability.
Because the wavelength of emitted EM radiation varies with the temperature of the source, it does so in the form of longer - wave IR than that received from the Sun — the Earth's surface is significantly cooler than that of the Sun.
Okay, one little nit - picky issue with Q2 is that O2 and N2 actually DO absorb infrared radiation, just at shorter wavelengths than matter for the Earth's infrared emission spectrum (3 - 27 microns, with a peak around 9 microns or so).
1) Although it receives slightly less radiation from its host star than the Earth, that is not really an issue.
More to the point though, CO2 (or H2O or whatever) absorption of IR radiation does not depend on the earth's blackbody or brightness temperature being higher than the mean temperature of the atmosphere (and the CO2).
Can CO2 at ~ 1 km, ~ 6C colder than the surface and the earth's brightness temperature, not absorb any of the earth's IR radiation?
Likewise, CO2 at a mean temperature less than the earth's brightness temperature still absorbs radiation.
The net result is, earth receives a lot less infrared radiation from the sun than it radiates away.
Actually, though, most of the OLR originates from below the tropopause (can get up around 18 km in the tropics, generally lower)-- with a majority of solar radiation absorbed at the surface, a crude approximation can be made that the area emitting to space is less than 2 * (20/6371) * 100 % ~ = 0.628 % more than the area heated by the sun, so the OLR per unit area should be well within about 0.6 % of the value calculated without the Earth's curvature (I'm guessing it would actually be closer to if not less than 0.3 % different).

The moon, for example, is much cooler than the Earth, but as you noted, it radiates energy because it's temperature is above zero K. Certainly you are not suggesting that the Earth has some «smart shield» around it that redirects the radiation from the moon, but lets the sun's radiation in.
