Abstract

In the article "The global carbon dioxide budget" by Eric T. Sundquist (12 Feb., p. 934), the second sentence of the third paragraph on page 935 should have read, "The ice core record from the Byrd station in Antarctica shows that CO2 concentrations rose from 200 ppm between 17,000 and 18,000 years ago to 280 ppm between 10,000 and 11,000 years ago (2)." The sixth sentence of the second paragraph of column three on the same page should have read, "There is some evidence for a significant deglacial change in terrestrial chemical weathering (10)." The seventh sentence of note 66 on page 941 should have read, "I calculated the latitudinal distribution of the authors' tropical deforestation flux by assuming proportionality to the biospheric destruction terms in (50)."
