You don't think carbon dioxide is a heat trapping gas aka greenhouse
gas?
You don't think CO2 is being spewed into the air by cars and coal plants
etc?
You don't think the earth will warm any more than it has even with
increased CO2?
Correct. Is man responsible. Other than the local Urban Heat Island
Effect (which is well documented but ignored by AGW supporters) I can
find no large scale effect that is provable.
No, CO2 IS a GHG. However, it operates on a logarithmic scale
You tell us you can find no large scale effect that is provable. So...
you must reject the Greenhouse Effect. Yet in the same breath you say
CO2 is a Greenhouse Gas. Which is it?
And it operates on a LOGARITHMIC scale. Is that, like, a magic word for
you? You're suggesting that the Earth's CO2 climate sensitivity has
gone to zero. Do you have any evidence to support that idea?
I can give you a logarithmic function that will stop warming with the
very next atom of CO2 and I can give you a logarithmic function whose
warming wouldn't detectably slow for a hundred million years. Telling
us it "operates on a logarithmic scale" tells us precisely NOTHING.
also operates in the same wavelengths as H2O vapor. Which is THE
dominant GHG.
Is that provable? Have you seen some large scale provable effect?
Water vapor IS the most significant greenhouse gas. It is NOT, however,
a significant factor with respect to
global warming. The amount
of water vapor the Earth's atmosphere can hold is dependent on the
global temperature. Any excess will precipitate out of the system in
days, any shortcoming will be replaced by evaporation in days. It
cannot accumulate beyond the capacity the Earth's temperature dictates.
The same is NOT true for CO2, whose atmospheric levels are dependent on
the rate of supply and the ability of the Earth's various CO2 sinks to
absorb it. It is clear, however, that even were all human CO2
production to cease this instant, it would be centuries before
atmospheric levels returned to preindustrial values. Therefore, the
global warming potential of any particular unit of CO2 is thousands of
times greater than a similar unit of water vapor.
Man contributes 5% of the total global CO2 budget.
When you say "total global CO2 budget, you're obviously counting what's
held in the oceans, the soil and the planet's biota. CO2 that's NOT in
the atmosphere has no direct effect on global warming. So, let stop
trying to kid ourselves and look just at what's in the atmosphere
absorbing IR. There, man is responsible for 120/400ths or 30% of the
world's CO2. And as we all know, that level is increasing.
In the presence of ever increasing CO2 levels (far above what even
Hansen predicted was possible) the global temperature has remained flat
for 16 plus years. That means the AGW theory is a failure.
For the umpteenth time, 1941-1979 says this oft-repeated line is a
complete crock of
SHIT. The climate's
behavior of the last 15 years is
WELL within the demonstrated
natural variation.
Time to face facts. AGW is real and represents a real threat to human
infrastructure and much of the world's plant and animal life.
