Carbon Dioxide

The fundamental reason why

by

The fundamental reason why carbon dioxide in the atmosphere is critically important to biology is that there is so little of it. A field of corn growing in full sunlight in the middle of the day uses up all the carbon dioxide within a meter of the ground in about five minutes. If the air … Read more

This treaty [Kyoto] is, in our opinion, based upon flawed ideas. Research data on climate change do not show that human use of hydrocarbons is harmful. To the contrary, there is good evidence that increased atmospheric carbon dioxide is environmentally helpful…agreement would have very negative effects upon the technology of nations throughout the world, especially … Read more

The Earth is warming

The Earth is warming but physical evidence from around the world tells us that human-emitted carbon dioxide has played only a minor role in it. Instead, the mild warming seems to be part of a natural 1,500-year climate cycle (plus or minus 500 years) that goes back at least one million years. Fred Singer

The correlation of increasing warmth with increasing carbon dioxide concentrations is particularly weak; that with solar energy and with ocean movements is much stronger. Don Aitkin
