Certain lakes in Africa reported to belch CO2 from rotting veg in the lake bottom. Sudden release, the CO2 drifts down the lowest valley out of the lake, everything dead down wind. Cows, dogs, people, birds. The CO2 is rapidly taken up by growing plants and cleared from the air. Big mystery until solved by investigations.
Stage and movies productions, low mystery fog, produced by dry ice= CO2. Heavier than air.
Surface growing plants, land and sea, take up CO2 instantly when in contact. CO2 is basic plant food. 85% of Earth covered by oceans. Land plants minor users of CO2 in comparison to the sea plants and buffer systems.
CO2 atomic wt. -44. O2 -32. N -28. H2O -18. Clouds(water vapor) on a hot day can only get up to the mid 20,000 ft.
Fuel burned above 30,000 ft (jet fuel) main way CO2 gets into the upper atmosphere in large quantities. 2-5 tons per hr per engine. 3.66 tons of CO2 /ton of fuel burned. Settles down slowly.
