Re: Global Warming - what's behind it?

& just to back it up a little further ...

"Acute carbon dioxide toxicity is sometimes known as Choke damp, an old mining industry term, and was the cause of deaths at Lake Nyos in Cameroon, where an upwelling of CO2-laden lake water in 1986 covered a wide area in a blanket of the gas, killing nearly 2000. The lowering of carbon dioxide in the atmosphere is largely due to absorption by plants, which convert it to sugars through photosynthesis. Phytoplankton photosynthesis absorbs dissolved CO2 in the upper ocean and thereby promotes the absorption of CO2 from the atmosphere."
