CO2 is heavier than air

What the science says...

Climate Myth...

CO2 is heavier than air

Comments

Comments 1 to 1:

  1. “Pure CO2 is indeed heavier than air and there have even been suffocation deaths caused by volcanic emissions of CO2 many times in human history. The one word answer is wind. The atmosphere is very turbulent (windy) and this turbulence easily dilutes many kinds of gases in the atmosphere and overpowers any small differences in buoyancy [due to molecular weight differentials].” From http://scienceblogs.com/illconsidered/2010/10/is_co2_well_mixed.php There’s a more detailed discussion of this topic at the source: Is CO2 well mixed?
