re: 280,000,000,000,000 tonnes of liquid CO2
How many diet cokes would it take to equal this much carbonation... I am convinced that this whole global warming thing can be laid at the feet of big-cola. Evil capitalist corporations like Coca-cola keep putting carbon into beverages and of course that carbon makes its way out of the cola and into the atmosphere.
I drink my cokes very fast so as not to allow too much the carbonation to escape into the atmosphere. I suggest that we start a campain to get all americans (the biggest cola-consumers) to do the same. There is no telling how much effect on the world mean-tempature this simple measure could have. Maybe as much as 1-degree celcius over a 1000 year time frame.
(I hope its not to late already)
