Due to climate change, including rising temperatures, more and more methane is bubbling up from lakes, ponds, rivers and wetlands throughout the world. The release of methane -- a potent greenhouse gas -- leads to a further increase in temperature, thus creating a positive feedback loop (also known as a 'vicious circle'). This is the conclusion of a team of biologists led by Radboud University in an article published in Nature Communications on Nov. 22.
Three new research studies from the University of Texas at Arlington have found harmful pathogenic bacteria in Texas groundwater near unconventional natural gas extraction sites.
In a new study, geophysicists from the University of Pennsylvania found that granular segregation helps explain the tendency of riverbeds to be lined by, or 'armored' with, a layer of relatively larger particles.
The first observation of a super-hydrated phase of the clay mineral kaolinite could improve our understanding of processes leading to volcanism and affecting earthquakes. In the lab, scientists created conditions similar to those in subduction zones where an oceanic plate dives under the continental crust. Transport of water with subducting plates causes volcanic activity. The team led by scientists from Yonsei University in the Republic of Korea presents its results in the journal Nature Geoscience.
Researchers studying a rapid global warming event, around 56 million years ago, have shown evidence of major changes in the intensity of rainfall and flood events. The findings indicate some of the likely implications should current trends of rising carbon dioxide and global warming continue.
Treated excrement from turkeys, chickens and other poultry, when converted to combustible solid biomass fuel, could replace approximately 10 percent of coal used in electricity generation, reducing greenhouse gases and providing an alternative energy source, according to a new study by Ben-Gurion University of the Negev (BGU) researchers.
How a species of fly subverted nature to forage in a caustic underwater habitat.
Urgent action is required to stem the loss of the world's seagrass meadows to protect their associated fisheries.
Groundwater depletion could be significant source of atmospheric carbon dioxide.
Groundwater recharge in the Western US will change as the climate warms -- the dry southern regions will have less and the northern regions will have more, according to new research. The new study covers the entire US West, from the High Plains states to the Pacific coast, and provides the first detailed look at how groundwater recharge may change as the climate changes. Groundwater is an important source of freshwater, particularly in the West.
