The atmosphere consists mainly of n

The atmosphere consists mainly of nitrogen ( 78 per cent), oxygen ( 21 per cent) and argon ( 0.9 per cent): the remaining 0.1 per cent includes trace gases that are active in causing global warning. The amounts of these “greenhouse gases” in the atmosphere varied before humankind appeared, due to volcanic emissions , or because of fluctuations in biogeochemical cycles or because climate changed. However, during roughly the last two centuries, human activity has been increasing the atmosphere concentration of some greenhouse gases at rates which probably pose a significant threat to global climate
