CO2 transmits visible light easily. So light from the sun goes right through it on the way down.
The suns light warms the earth. Heat (infrared light) heads back up.
But the CO2 blocks infrared light. So the heat is kept in.
Most things either don't block any light very much, or block both visible and infrared. Only things which transmit visible and block infrared, like CO2 and methane, and a few other things, cause a big greenhouse effect.

Solar radiation travels from the sun and enters earths atmosphere. Very little is absorbed until it hits the surface of the planet whereby it is redistributed as thermal or heat radiation. People think that carbon dioxide it the major constituant of the greenhouse effect but it is actually water vapour which keeps most of the heat in. Thermal radiation is absorbed by water vapour, carbon dioxide and methane. As for krazyk, you are wrong. Carbon dioxide does not 'rip a hole' in the ozone layer. Chloro fluoro carbons can deplete ozone and there isn't actually a hole produced, more like a thinning of the ozone layer.

Carbon Dioxide helps to trap the sun's heat within our atmosphere. Without it, we would not be able to survive the cold temperatures. Too much of it contributes to global climate changes. The more CO2, the more of the sun's heat is trapped, and the warmer we become.

Carbon Dioxide plays with the Ozone because when it goes to the Ozone reserve it messes it up. the ozone is O3. and the carbon Dioxide breaks apart the 03 and tears a hole in our atomosphere.

since the rays of the sun has greater frequency, they are able to reach the earth's surface! but their frequency gets lower after heating the earth's surface. co2 doesnot let go the rays of lower frequency, so they get trapped around the earth. this helps in heating the surface and greenhouse effect takes place. resulting into the melting of polar caps and heating the temperature!!

because of the solids in it yes
