Deep stores of carbon in northern peatlands may be safe from rising
temperatures, according to a team of researchers from several U.S.-based
institutions.
And that is good news for now, the researchers said.
Florida
State University research scientist Rachel Wilson and University of
Oregon graduate student Anya Hopple are the first authors on a new study
published today in Nature Communications. The study details
experiments suggesting that carbon stored in peat—a highly organic
material found in marsh or damp regions—may not succumb to the Earth's
warming as easily as scientists thought.
That means if these
northern peatlands—found in the upper half of the northern
hemisphere—remain flooded, a substantial amount of carbon will not be
released into the atmosphere.
"We do see some breakdown of peat on
the surface, but not below 2 feet deep, where the bulk of the carbon is
stored," Wilson said.
The study is part of a long-term look at
how carbon stored in peat will respond to climate and environmental
change. The team of researchers, led by Paul Hanson of the Oak Ridge
National Laboratory, includes scientists from FSU, University of Oregon,
Georgia Institute of Technology, the U.S. Department of
Agriculture-Forest Service, Chapman University, Lawrence Livermore
National Laboratory, Pacific Northwest National Laboratory and Oak Ridge
National Laboratory.
