Latest Carbon cycle Stories
Rising Arctic temperatures are causing permafrost soils to thaw at unprecedented rates, and NASA scientists are currently looking into just how much greenhouse gas is being released through soil decomposition.
A new study, published in Nature Geoscience, suggests that human activity might be increasing the transition of carbon from land to rivers, estuaries and the coastal zones. This indicates that large quantities of anthropogenic carbon might be hidden in previously unconsidered regions.
Along with other sea organisms, jellyfish are part of the ocean’s natural carbon recycling process. Jellyfish eat microscopic plankton and consequently ingest broken down carbon dioxide. Dead jellyfish then sink to the bottom of the ocean taking a large amount of carbon with them. This carbon becomes trapped in the deep sea water, allowing room for more carbon dioxide to dissolve into the ocean.
The Amazon rainforest is known as the lungs of the planet because it inhales carbon dioxide and exudes oxygen into the atmosphere. The plants of the forest use the carbon dioxide to promote leafy growth, which eventually falls to the ground and decomposes or washes away by the region’s plentiful rainfall.
More carbon dioxide is released from residential lawns than corn fields according to a new study.
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.
