Incoming solar radiation strikes Earth's atmosphere in the form of visible light plus ultraviolet and infrared radiation

Ultraviolet (UV) radiation has a higher energy level than visible light and infrared (IR) radiation has a weaker energy level.

Some of the sun's incoming radiation is absorbed by the atmosphere the oceans and the surface of the Earth.

For Earth's temperature to remain stable the amount of incoming solar radiation should be roughly equal to the amount of IR radiation leaving the atmosphere.

Some of these historical changes can be attributed to changes in the amount of solar radiation hitting the planet.

However there is no evidence that any increase in solar radiation could be responsible for the steady increase in global temperatures that scientists are now recording according to the National Oceanic and Atmospheric administration (NOAA.

Venus on the other hand has a very dense atmosphere that traps solar radiation; the average temperature on Venus is about 864 degrees F (462 degrees C).
