Dynamic showing CO2 production http://www.youtube.com/watch?v=j1ehcjjDPy8&feature=player_embedded[^] whatever you think take a look, its quite mesmeric!
"It is a remarkable fact that despite the worldwide expenditure of perhaps US$50 billion since 1990, and the efforts of tens of thousands of scientists worldwide, no human climate signal has yet been detected that is distinct from natural variation."

why does the southern hemisphere have a constant low amount of co2?
- Industrial civilization (CO2 production) is much more prevalent in the northern hemisphere 2) Higher percentage of ocean (CO2 absorber) in the southern hemisphere 3) The northern and southern hemispheres tend to circulate mostly independently Haven't had a chance to watch the video (Blocked from YouTube), but off the top of my head, those seem to be reasonable hypotheses... Granted, I'm no climatologist, so I could be wrong.

It more an average than a low. The NH goes from high in winter, lots of people, lots of land, zero plant activity, to a low in summer, lots of land, lots of plants sucking up the winters CO2 production. In the south, there isnt the massive landmasses and therefore isnt the life that produces and consumes, CO2.

Author of the Guardians Saga (Sci-Fi/Fantasy novels)Yeah, thats about it. Its interesting how between winter and summer the NH Co2 varies widely.

Well, again... Not a climatologist, and didn't see the actual video, but I can make a few guesses... 1) Could be they're only measuring in a certain altitude range for this visualization... Maybe when the air is warmer, the CO2 floats higher (Or lower?) 2) Plants shed their leaves in the winter, so photosynthesis stops (Except for pine trees and the like)... Less CO2 is being absorbed by the biosphere. 3) If the oceans are warmer in the summer (Do they actually warm? Just guessing here), maybe they can hold more CO2.

Author of the Guardians Saga (Sci-Fi/Fantasy novels)Yep, thats whats behind the variation. As far as I know its some kind of satellite based data, and its probably in the toposphere, since thats the zone of interest.

I don't like how they have used a dynamic scale. It gives a false impression of whats happening. They should have used a static colour scale for the full range of CO2 concentrations across the entire simulation. Watch the numbers at the bottom, they shift left constantly, had they left them static, and it might be actually possible to see the concentration levels rise across the whole ecosystem, rather than just see the masses shift about.
