Carbon dioxide is a greenhouse gas (GHG). It traps heat in our atmosphere, causing the planet's temperature to increase. This increase will result in the spread of tropical diseases, flooding of low lying areas, more frequent and violent storms, increased desertification of some areas, and other long term economic hardships. 350 parts per million (ppm) is considered by many scientists to be close to the maximum sustainable level for CO2. We will pass 400 ppm in 2015, and levels will continue to rise for decades to come. We don't know all the bad things that will happen, but we are sure to find out.

UV radiation can break up carbon dioxide in the upper atmosphere and increased flux of UV could result in increased photodissociation (the effect of radiation breaking up molecules).
But this would still be in the upper atmosphere and carbon dioxide is mainly concentrated at the surface/troposphere. Carbon dioxide is a relatively trace element (very low concentration) in the ionosphere and upper thermosphere, where UV radiation has an effect on Earth's atmosphere
The ozone layer has the greatest effect on the amount of ultraviolet radiation received at the earth's surface from the Sun. Cloud formation and atmospheric thickness, in combination with solar angle, have the greatest effect on the amount of visible and infrared radiation received at the earth's surface from the sun
Carbon dioxide is being released. As you breathe in you inhale fresh oxygen, but as you breathe out your body releases carbon dioxide.
Variable.
The greenhouse effect refers to the change in the thermal equilibrium temperature of a planet or moon by the presence of an atmosphere containing gas that absorbs and emits infrared radiation. Greenhouse gases, which include water vapor, carbon dioxide and methane, warm the atmosphere by efficiently absorbing thermal infrared radiation emitted by the Earth's surface, by the atmosphere itself, and by clouds. As a result of its warmth, the atmosphere also radiates thermal infrared in all directions, including downward to the Earth's surface. Thus, greenhouse gases trap heat within the surface-troposphere system.
The earths atmosphere has significantly altered over the years. The process of the earth's atmosphere was recognized and evolved 2.7 billion years ago, forming the nitrogen-oxygen atmosphere that exists today. This change enabled the formation and beginning of the ozone layer (which along with magnetic fields) block solar radiation.
Some of the gases found in our atmosphere which absorb infrared light are: carbon dioxide, methane, and water vapor. Gases found in our atmosphere which absorb ultraviolet light are ozone (O3) and oxygen gas (O2).
Greenhouse gases like carbon dioxide, methane and water vapour absorb infra-red radiation as it comes off the surface of the earth.
Absorption of ultraviolet radiation by carbon dioxide.
No, increases in carbon dioxide in your atmosphere would cause a warming trend.

It might be similar to the atmosphere on Venus, where the oxygen has combined with surface rocks and as carbon dioxide. On Earth, plants remove carbon dioxide and increase the level of free oxygen that supports animal life. This atmosphere also reduces ultraviolet radiation, which also affects the level of gases.
The most important gas which absorbs Uv radiations from the sun is ozone. This ozone is present in the form of ozone layer in the atmosphere.
Indirectly yes. It causes global warming, which increases carbon dioxide in the atmosphere.
The increase in carbon dioxide in the atmosphere means that more solar radiation (in the form of infra-red heat from the warmed earth) is absorbed in the atmosphere and prevented from escaping to space. It will not change the transmission of incoming solar radiation through the atmosphere.
