Abstract
The steadily increasing global carbon dioxide concentration is further recognized through the decreasing trend of 13C/12C isotopic ratio in the annual rings of twentieth-century trees. The decrease is averaged to about 0.012 per mil per year which is attributed not only as due to anthropogenic fossil-fuel burning but also to the man’s impact on the land pattern.
