Carbon dioxide density & distribution in the atmosphere

Seniour Baloc

carbon dioxide is heavier than air, so how there is a layer of CO2 is forming around the atmosphere?

As far as I know there is no layer of CO₂ forming around the atmosphere. Do you have any source to backup the claim?

Then what is the reason of Global Warming?

Borek

Global warming is a banned topic here, but the question is actually not about GW. You are misunderstanding the mechanism of the greenhouse effect. It doesn't require a layer of carbon dioxide anywhere, all it requires is a presence of the carbon dioxide in the atmosphere.
