Latest Carbon cycle Stories
A new global-scale modeling study that takes into account nitrogen – a key nutrient for plants – estimates that carbon emissions from human activities on land were 40 percent higher in the 1990s than in studies that did not account for nitrogen.
Despite widespread use of fertilizers and nitrogen emissions by industrial processes, the amount of atmospheric nitrogen has remained consistent over the past 500 years, according to a new study in Nature.
A continental-scale chemical survey in the waters of the eastern U.S. and Gulf of Mexico is helping researchers determine how distinct bodies of water will resist changes in acidity.
A new study led by Oregon State University reveals that the greatest battle in Earth's history has been going on for hundreds of millions of years. And the battle, which no one knew existed until now, is far from over.
Researchers studying Arctic thermokarst failures in Alaska were alarmed to find climate-warming carbon dioxide gas may be releasing into the atmosphere at an unprecedented rate.
Using a new research tool, scientists have discovered that forest death in the Amazon is higher than previously believed, a finding that casts a dark shadow on the future of climate change.
A research team from the University of California – Santa Barbara, led by Mariah S. Carbone, studied the influence of clouds on the largest Bishop pine forest of Santa Cruz Island.
A new analysis led by NASA's Jet Propulsion Laboratory, Pasadena, Calif., has estimated how much the growth of plants worldwide is limited by the amount of nutrients available in their soil.
Phytoplankton are important for the sustainability of the aquatic food web. However, future warming oceans could significantly alter the populations of these important organisms.
Recently, an international collaboration headed by Tom Battin from the Department of Limnology at the University of Vienna looked at an little-studied example of a carbon cycle. His team’s task was to explore and determine the role of Alpine glaciers in the carbon-cycling process. Glaciers are, in effect, nature’s freezers. Items that were deposited into the glaciers over several millennia became locked in a frozen tomb. And it is only on account of unprecedentedly rapid glacial melt...
