Why are green house gases causing a problem?
Green House gases work by allowing the Sun's rays into the
atmosphere, but don't let them back out. Green-house gases are
gases like CO2, Methane and other traces of elements. A small
amount is necessary to control the warmth of the overall planet,
but if we get to much green-house gas, the planet could begin to
warm, which it is. If this is due to green-house gases or not,
there is much controversy to the matter.
