Freshwater methane release changes greenhouse gas equation
Date:1/6/2011

AMES, Iowa An international team of scientists has released data indicating that greenhouse gas uptake by continents is less than previously thought because of methane emissions from freshwater areas.

John Downing, an Iowa State University professor in the ecology, evolution and organismal biology department, is part of an international team that concluded that methane release from inland waters is higher than previous estimates.

The study, published in the journal Science, indicates that methane gas release from freshwater areas changes the net absorption of greenhouse gases by natural continental environments, such as forests, by at least 25 percent. Past analyses of carbon and greenhouse gas exchanges on continents failed to account for the methane gas that is naturally released from lakes and running water.

Downing, a laboratory limnologist at Iowa State, has also conducted research measuring the amount of carbon sequestered in lake and pond sediment. This new study gives scientists a better understanding of the balance between carbon sequestration and greenhouse gas releases from fresh water bodies.

"Methane is a greenhouse gas that is more potent than carbon dioxide in the global change scenario," Downing said. "The bottom line is that we have uncovered an important accounting error in the global carbon budget. Acre for acre, lakes, ponds, rivers and streams are many times more active in carbon processing than seas or land surfaces, so they need to be included in global carbon budgets."

Methane emissions from lakes and running water occur naturally, but have been difficult to assess. David Bastviken, principal author and professor in the department of water and environmental studies, at Linkping University in Sweden, said small methane emissions from the surfaces of water bodies occur continuously.

"Greater emissions occur suddenly and with irregular timing, when methane bubbles from the sedi
