How does carbon dioxide tread on the steps?

How does carbon dioxide step through the steps? Interesting experience can be demonstrated in chemistry lessons. In a large can of 3-4 liters we put a ladder of tin. For each step of the stairs we put a small candle stump. We light all the candles. The tube, lowered to the bottom of the can, is let in from Kipp's apparatus carbon dioxide gas. It is heavier than air. Gradually, carbon dioxide extinguishes the candles, filling the jar, as if walking along the steps.

A distinctive feature of the greenhouse properties of carbon dioxide in comparison with other gases is its long-term effect on the climate, which, after the cessation of the emission that caused it, remains largely constant for up to a thousand years. Other greenhouse gases, such as methane and nitrogen oxide, exist in the free state in the atmosphere for a shorter time.

The decay of organic material, such as dead trees and grass, leads to the annual allocation of 220 billion tons of carbon dioxide, the earth's oceans allocate 330 billion. During the Indonesian forest and peat fires in 1997, 13-40% of the average annual CO2 emissions were allocated, obtained as a result of the combustion of fossil fuels.

In the normal state, these natural sources are in equilibrium with the physical and biological processes that remove carbon dioxide from the atmosphere - part of the CO2 is dissolved in seawater and some are removed from the air in the process photosynthesis.
