To a good approximation, the Earth gets all its energy from the sun in the form of short - wave solar radiation (sun light).

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).

Indeed solar power is a good idea and the plants have the cheapest technology to harvest electromagnetic radiation from the sun by using simple photosynthetic processes.

This is why (absent sufficient solar or other non-LW heating) the skin temperature is lower than the effective radiating temperature of the planet (in analogy to the sun, the SW radiation from the sun is like the LW radiation, and the direct «solar heating» of the part of the atmosphere above the photosphere may have to due with electromagnetic effects (as in macroscopic plasmas and fields, not so much radiation emitted as a function of temperature).

The temperature around the world is now increasing and TSI (Total Solar Irradiance) I think solar cycle can cause global warming because our temperature is increasing by radiation from the sun which comes from solar cycleSolar Irradiance) I think solar cycle can cause global warming because our temperature is increasing by radiation from the sun which comes from solar cyclesolar cycle can cause global warming because our temperature is increasing by radiation from the sun which comes from solar cyclesolar cycle too.

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.

So we can blame the sun for the Holocene period, but even though solar radiation has increased right along with the temperature in the 20th century, we are assuming that the warming is due to the minute increase of atmospheric CO2 from humans?

it's much more reasonable to conclude that our solar system is receiving more radiation, either from the sun or nearby stars, for whatever as yet unknown reason.

Energy for the ocean circulation (and for the atmospheric circulation) comes from solar radiation and gravitational energy from the sun and moon.

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.
