Question

the spirit of large production of carbon di oxid through the respiration and combustion the actual amount of these gases is our atmosphere is very less why​

Answer 1

Carbon dioxide (CO2) is the 5th most abundant gas in the atmosphere and, together with water vapor, probably the best known of the greenhouse gases.



Most everyone agrees that human activities are causing the atmospheric concentration of carbon dioxide to slowly increase.   We'll look at some of the experimental evidence in a moment.



   

Not everyone agrees however about the effect that increasing amounts of CO2 will have on the earth's energy budget and climate.  The worry is that increasing greenhouse gas concentrations will strengthen the greenhouse effect and will cause the earth's surface to warm.
