Conduction and thermal
radiation are two ways in which heat is transferred

Climate is driven largely
by energy
from the
sun, and the manner in which this incoming solar

(mostly
by faster transport of

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).

To me, it is more likely the fluctuation in E-UV coming

The latter gives rise to a strong negative feedback between the surface temperature Ts and the temperature of «absolutely black body» Tbb, which is determined
by the solar

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
