there is no high C02 levels , the atmosphere acts like an accumulator , plants and trees always purge C02 from the atmosphere and
restore much of the 02 used in IC engines to the atmosphere
which is
confirmed by
stable
02
levels
in the atmosphere
and
C02 is not contributing to the current declining/decreasing temperature of the planet

the question is what about the H20 ?
how is the 02 from the H20 being restored to the atmosphere ?
we know it is because 02 levels in the atmosphere are stable / constant

since we know the by product of combustion is
primarily
H20 + C02
and 02 levels are stable (in our atmosphere) , then using KISS
something is also restoring the 02 from the H20

the only way to reduce C02 output is to combust less HC
since HC + 02 are the inputs to combustion
and
H20 + C02 are the (primary) outputs of combustion

for the most part
input ratio is fixed at 14.64 parts air to 1 part HC
so , since 02 is 20% of the air

about
3 parts 02 to 1 part HC

a smaller engine or same engine and lower rpm are the only way you can reduce either C02 or H20 outputs of a IC engine
the outputs ratios are fixed by the input ratios
no rocket science involved

would you say clouds (H20 vapors) are
significant
greenhouse gases ? yes you would
is H20 vapors a byproduct of combustion ?
yes it is
yet
the overall temperature of the planet is decreasing and has been for a few years ... are the two related ?
hell no .
are ocean levels rising ? no they are not -
so
we know 02 in the atmosphere is stable and there is no additional H20 in the oceans ...
then
what is separating the H20 back to h2 and 0 ?
what becomes of the H2 ? we know where the 0 is .
thank me

Chaz, can you elaborate on the emissions percentages for cold/warm ice's?
