Over 99.9% of the earth’s atmosphere consists of nitrogen, oxygen, and argon.
Whereas CO2 makes up about 95% of the atmospheres of Venus and Mars, it currently accounts for only about 0.038% of the earth’s atmosphere (i.e. 380 parts per million), compared with a pre-industrial revolution figure of about 0.028%.
Water in its various forms ranges from 0 to 4% of the atmosphere and its properties vary according to what form it is in and the altitude at which it is found.
Humans are responsible for about 3.4% of the CO2 emitted to the atmosphere annually, mostly from the burning of coal, oil, and natural gas, and the production of cement; the rest comes from natural sources such as volcanoes, the outgassing of the oceans, and the biosphere.
Humans are probably responsible for about 2.5% of the total greenhouse effect
