Warming pushes Western US toward driest period in 1,000 years
During the second half of the 21st century, the U.S. Southwest and Great Plains will face persistent drought worse than anything seen in times ancient or modern, with the drying conditions "driven primarily" ...
Buried fossil soils found to be awash in carbon
Soils that formed on the Earth's surface thousands of years ago and that are now deeply buried features of vanished landscapes have been found to be rich in carbon, adding a new dimension to our planet's ...
Study casts doubt on climate benefit of biofuels from corn residue
Using corn crop residue to make ethanol and other biofuels reduces soil carbon and can generate more greenhouse gases than gasoline, according to a study published today in the journal Nature Climate Change.
Experiments open window on landscape formation
University of Oregon geologists have seen ridges and valleys form in real time and—even though the work was a fast-forwarded operation done in a laboratory setting—they now have an idea of how climate ...
Soil water, microbes influence carbon in world's coldest desert, study finds
Soil water and microbes' respiration contribute to fluctuations of carbon dioxide in the world's coldest desert, where climate change is expected to increase underground moisture and microorganisms, an Arizona ...
Fungi essential for land plants live with mysterious bacteria
Soil fungi colonize roots and provide essential nutrients for the majority of the world's land plants, but new research sheds light on a class of bacteria found living within these fungi.
Crashing comets may explain mysterious lunar swirls
Brown University researchers have produced new evidence that lunar swirls—wispy bright regions scattered on the moon's surface—were created by several comet collisions over the last 100 million years.
Study shows isopods may dampen impact of global warming on forest soil
Human security at risk as depletion of soil accelerates, scientists warn
Steadily and alarmingly, humans have been depleting Earth's soil resources faster than the nutrients can be replenished. If this trajectory does not change, soil erosion, combined with the effects of climate ...
Soil nutrients may limit ability of plants to slow climate change
Many scientists assume that the growing level of carbon dioxide in the atmosphere will accelerate plant growth. However, a new study co-written by University of Montana researchers suggests much of this growth ...
Researchers predict gradual, prolonged release of greenhouse gases from thawing permafrost
There's qualified good news about one contributor to climate change, say researchers who have crunched data from a series of recent studies.
Study finds that soil carbon may not be as stable as previously thought
Increased plant growth caused by rising atmospheric carbon dioxide is associated with higher rates of carbon dioxide release from soil. If rising carbon dioxide enhances soil carbon storage at all, the effect ...
Scientists predict gradual, prolonged permafrost greenhouse gas emissions
A new scientific synthesis suggests a gradual, prolonged release of greenhouse gases from permafrost soils in Arctic and sub-Arctic regions, which may afford society more time to adapt to environmental changes, ...
Climate change, plant roots may accelerate carbon loss from soils (Update)
Soil, long thought to be a semi-permanent storehouse for ancient carbon, may be releasing carbon dioxide to the atmosphere faster than anyone thought, according to Oregon State University soil scientists.
