Solution to remove CO2 from air?

== Water does not have carbon dioxide in it. Example water = H2O (1 hydrogen, 2 oxygen) carbon dioxide = CO2 (1 carbon, 2 oxygen) == Some forms of water, including Seltzer water, carbonated soft drinks and some natural spring waters, do have carbon dioxide dissolved in them under pressure. The way to get rid of the CO2 in those forms of water is to leave the water out in an open container. The Carbon Dioxide will diffuse into the atmosphere in a day or so, depending on the temperature.
