climate change a significant change in global and regional climate patterns that is of current concern and is associated with an increase in carbon dioxide and certain other gases in Earth's atmosphere which contribute to global warming. [1/2 definitions]

external respiration the exchange of carbon dioxide and oxygen across external or respiratory surfaces, such as gills, in multicellular organisms.
hyperventilation unusually rapid and deep breathing that causes a loss of carbon dioxide from the blood and can lead to dizziness or fainting.
leavening an agent such as yeast or baking powder that causes the formation of carbon dioxide gas in batter or dough, causing it to expand and rise. [1/2 definitions]
