...The contribution from lakes (8–48 Tg yr21; Bastviken et al. 2004a) in combination with the likely emissions from large impoundments (70 Tg yr21; St. Louis et al. 2000) and an expected high but unknown amount of emission from the globally abundant small impoundments such as farm ponds (Downing et al. 2008) points to emissions from inland waters that are on the order of 100 Tg yr21 or more....

...Estimates of the total area of reservoirs vary (St. Louis et al. 2000; Shiklomanov and Rodda 2003; Lehner and Döll 2004), but it is clear that their area is substantial compared to that of natural lakes (Downing et al. 2006)....

...Our estimate increases this unknown sink of CO2 by approximately 20%, from 1.3 Gt/yr of carbon (Houghton et al. 1996) to 1.6 Gt/yr of carbon (0.3 Gt/yr of carbon as C–CO2; Table 3), by effectively increasing the anthropogenic CO2 emissions to the atmosphere....
