Now, if you have all this very cold, nearly freezing water surrounding these ice caps, sucking up
carbon dioxide out of the polar atmosphere, at nearly the highest possible rate, 30 times faster

carbon -
dioxide than man would
do alone.
I have yet to see a serious challenge to the math on this
done by Vaclav Smil of the University of Manitoba, who has noted that handling just 10 percent of today's
carbon dioxide emissions would require more pipelines and other equipment
than is now used worldwide to extract oil — a precious commodity — from the ground.
While a handful of projects have captured
carbon dioxide, compressed it, and pumped it into the ground, they have
done so on a scale of no more
than about 1 million tons a year.
The gasoline also
did contain some hydrogen that burned to form water, so the 3:1 ratio Jeff references probably was for gasoline (not containing ethanol) but adjusted for the mass content of the hydrogen in the gasoline and is likely more accurate
than the 3.67 ratio of
carbon to
carbon dioxide masses.
But even when
carbon dioxide does make its way out of the atmosphere, Earth's natural systems can release other
carbon dioxide molecules that were previously stored in the oceans / land back into the atmosphere, making the full effect of
carbon dioxide emissions on surface temperatures much longer

The specific heat of water vapour is higher
than that of
carbon dioxide, so it will reduce the gradient slightly, and thus have a cooling effect, just as it

As a real gas
carbon dioxide is of course one and half times heavier
than air, so will always sink displacing air unless their is some work being
done to change that, and it's not always windy..
