Solar Radiation And Greenhouse Effect

To get the energy back in balance the surface of the earth has to warm up so that it will emit more infrared energy some of which will leave the atmosphere and compensate for the effect of the added greenhouse gases.

Solar radiation and greenhouse effect.

The greenhouse effect occurs when earth s atmosphere traps solar radiation because of the presence of certain gases which causes temperatures to rise. Photovoltaic greenhouses became popular in many countries for growing crops and at the same time generating electricity mainly for own usage to control the air temperature inside the greenhouse. However earth s greenhouse effect is getting stronger as we add greenhouse gases to the atmosphere. As variation of solar radiation is the single most important factor affecting climate it is considered here first.

Solar radiation is often called shortwave radiation. The greenhouse effect is the process by which radiation from a planet s atmosphere warms the planet s surface to a temperature above what it would be without this atmosphere. Solar radiation management does not remove greenhouse gases from the atmosphere and thus does not reduce other effects from these gases such as ocean acidification. While not an argument against solar radiation management per se this is an argument against reliance on climate engineering to the exclusion of greenhouse gas reduction.

For more than 40 years satellites have observed the sun s energy output which has gone up or down by less than 0 1 percent during that period. Without the greenhouse effect earth s temperature would be below freezing. Solar radiation is essential for their photosynthesis process for crop growing however high levels of solar radiation may adversely affect the crop quality. Warming from increased levels of human produced greenhouse gases is actually many times stronger than any effects due to recent variations in solar activity.

It is in part a natural process. Climate climate solar radiation and temperature. Adding more greenhouse gases decreases the amount of infrared radiation energy leaving the atmosphere. Of those gases known as greenhouse gases water vapor has the largest effect.

Radiatively active gases i e greenhouse gases in a planet s atmosphere radiate energy in all directions part of this radiation is directed towards the surface warming it. Air temperatures have their origin in the absorption of radiant energy from the sun. Greenhouse effect a warming of earth s surface and troposphere the lowest layer of the atmosphere caused by the presence of water vapor carbon dioxide methane and certain other gases in the air. It is called the greenhouse effect because of the similarity with the operation of the greenhouses.
