A large quantity of nitrogen compounds -- emitted into the atmosphere by humans through the burning of fossil fuels and the use of nitrogen fertilizers -- enters the oceans and may lead to the removal of some carbon dioxide from the atmosphere, concluded a team of international scientists led by Texas A&M University Distinguished Professor of Oceanography and Atmospheric Sciences Robert Duce.

The team of 30 experts from institutions around the world presented its conclusions in the current issue of the journal Science.

Human-caused atmospheric nitrogen compounds are carried by wind and deposited into the ocean, where they act as a fertilizer and lead to increased production of marine plant life. The increase in plant life causes more carbon dioxide to be drawn from the atmosphere into the ocean. This process results in the removal of about 10 percent of the human-caused carbon dioxide in the atmosphere, thus potentially reducing the climate warming potential, according to the team's paper.
