   No, it's the reaction product between water and CO2.

  The Columbia Encyclopedia, Sixth Edition. 2001.
carbonic acid
H2CO3, a weak dibasic acid (see acids and bases) formed when carbon dioxide
dissolves in water; it exists only in solution. Carbonic acid forms
carbonate and bicarbonate (or acid carbonate) salts (see carbonate) by
reaction with bases. It contributes to the sharp taste of carbonated
beverages.
