The gases that act as a shield that traps heatin the earth’s atmosphere, resulting ingreenhouse effect are called the greenhousegases.The gases in an atmospherethat absorbs and emits radiation withinthe thermal infrared range.

The meteorological conditions, includingtemperature, precipitation, and wind, thatcharacteristically prevail in a particular region.defined as the weather averaged over a longperiod.
Climate change happens whencertain elements in theatmosphere allow sunlight to passfreely, yet trap the light that isreflected back. Light enters theearth freely, but instead of leavingthe atmosphere after reflecting offthe ground, it gets trapped andthe earth just keeps on gettingwarmer and warmer.
Rising concentrations of greenhouse gasesgenerally produce an increase in the averagetemperature of the Earth. Rising temperaturesmay, in turn, produce changes in weather, sealevels, and land use patterns, commonly referredto as “climate change.”
