| Comments | "[Researchers'] analysis suggests that current estimates of global gross primary production, of 120 petagrams of carbon per year [BNID 101756], may be too low, and that a best guess of 150-175 petagrams of carbon per year better reflects the observed rapid cycling of CO(2). Although still tentative, such a revision would present a new benchmark by which to evaluate global biospheric carbon cycling models." |
