Conduction and thermal radiation are two ways in which heat is transferred from one object to another: Conduction is the process by which heat flows between objects in physical contact, such as a pot of tea on a hot stove, while thermal radiation describes heat flow across large distances, such as heat emitted by the sun.
But radiation from the sun and cosmic rays is 100 times stronger in space than on Earth, which is protected by a layer of ozone and the Van Allen radiation belts.

This may have to do with vitamin E's antioxidant properties — it can help fight cell damage caused over time by things like pollution and radiation from the sun.
(mostly by faster transport of radiation, which compensates for the CO2 slowdown, since tha amount of energy is fixed by what comes in from the sun) The failure to return to equilibrium means that the Laws Of Physics ie the Stefan - Boltzmann Law (SBL) is NOT allowed to function.
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).
So, here is my newbie question: Fig 1 shows earth receiving higher levels of infrared radiations from sun then the infrared radiation emitted by earth.

Energy is transferred from the Sun to the Earth by radiation, because radiation can pass through a vacuum.
Surface temperature is an imperfect gauge of whether the earth has been warmed by an imbalance between incoming radiation from the sun, and outgoing radiation, because of the role of ocean currents in the distribution of heat between deeper and surface waters.
If the amount of energy received by the Earth from the Sun exceeds the amount the Earth radiates into space, then the only thing the Earth can do is increase its temperature, which in turn will increase the amount of radiation into space.
Waters at this depth can not be warmed directly by the sun or greenhouse effect as solar radiation penetrates only to 100 metres depth, while infra - red radiation from the greenhouse effect can only warm the immediate surface «skin» of the ocean.
To me, it is more likely the fluctuation in E-UV coming from the sun that causes the warming and cooling effects by changing the reactions that are happening on TOA, i.e. O3, HxOx and NOx are rising now, causing more back radiation of F - UV, meaning less energy going in the oceans.
When sunspots are on the limb of the Sun — just rotating onto or off of the face — the plage are prominent from our vantagepoint, creating a significant increase in radiation that far outweighs the dip of radiation caused by the rest of the sunspot's transit.
You do not have the direct heat from the Sun which is the Sun's thermal energy in transfer by radiation.

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.
Earth's atmosphere also plays a vital role in regulating the temperature by providing a blanket of gases that not only protects us from excessive heat and harmful radiation from the sun, but also traps heat rising from the Earth's interior, keeping us warm.
