As nobody here can do these kind of sums, which I learnt in school some 55 years ago, the output from burning gasoline
by that formula is 54 % CO2 and 46 % H2O, and as none here is aware, the radiative forcing from atmospheric H2O relative to CO2 is about 2 - 4:1 in favour of H2O (Houghton, TAR and 2004), it is clear that burning fossil fuels is very beneficial to all of us,
by generating both CO2 and H2O each of which has enormous benefits for us
by increasing yields in agriculture,
livestock, forestry, and fisheries.
