Greenhouse effect.

Green house effect- the greenhouse effect is the rising of tempeture of the earths atmosphere due to gasses being trapped in the earths surface. Normally the gasses would pass back through the earths atmosphere but the rise in coarbon ammisions is trapping the gasses.The greenhouse effect is very important because without it the earth would not be warm enough to support human life. If the tempeture keeps rising as it is it will cause huge problems to humans, plants and animals.
