It doesn't matter if you call it carbon-neutral or not, the CO2 will
continue to rise if you continue to burn carbon-based fuels at the
current rate. The atmosphere doesn't know you switched to your
"carbon-neutral fuel." It continues to take the carbon out of the
atmosphere at the same slow rate that lags behind the rate we put it in.
This is what caused the rise. Growing more biofuel crops doesn't
automatically lower the atmospheric CO2, because there are already plants
growing on nearly all the arable land.

You keep saying "carbon-neutral" as if it were a fact that it would
reduce atmospheric carbon in some way. Prove it to us.

I'm sorry you are having problems reading. I never said it would reduce
atmospheric carbon, I said there would be no net gain. Neutral does not
mean subtraction or addition. Burning fossil fuels is addition.


I see where you are having difficulty. I am saying that as long as
emissions exceed assimilation, atmospheric CO2 will continue to rise. If
you are saying that if we start growing a lot of crops for biofuels, that
trend will stop, I have to respectfully disagree. The globe is already
covered with vegetation, and the oceans are full of blue-green algae, so
anything we can do by way of increasing crop growth will not be enough to
halt, or even slow significantly the rise of CO2 in our atmosphere.

If you are willing to debate me on this point, I'm quite willing to listen.
