Gore describes carbon dioxide as “global warming pollution.” It is not. It is food for plants and trees. Tests have shown that even at concentrations 30 times those of the present day even the most delicate plants flourish. Well-managed forests, such as those of the United States, are growing at record rates because the extra carbon dioxide in the atmosphere is feeding the trees. Carbon dioxide, in geological timescale, is at a very low concentration at present. Half a billion years ago it was at 7000 parts per million by volume, about 18 times today’s concentration.
 
Obviously, CO2 is both. Carbon dioxide is used by plants during photosynthesis to make sugars. Carbon dioxide is also a greenhouse gas as it absorbs strongly in the infrared wavelengths.
