The world's fastest-growing mud volcano is collapsing, with consequences for the surrounding environment, according to new research. (Durham University press release)

An abrupt release of methane about 635 million years ago from ice sheets caused a dramatic shift in climate, triggering a series of events that effectively ended the last "snowball" ice age, a new study reports. (University of California - Riverside press release)

An international team of scientists surveying the waters of the continental shelf off the West Coast of North America has discovered for the first time high levels of acidified ocean water within 20 miles of the shoreline, raising concern for marine ecosystems from Canada to Mexico.

A geographer from the University of Leicester has produced for the first time a map of the scorched Earth for every year since the turn of the millennium. (University of Leicester press release)

Researchers have found a way to reduce cloud-induced glare by as much as ten-fold in some cases when satellites measure blue skies on cloudy days, by using an indirect measurement of that reflected light. (DOE/Pacific Northwest National Laboratory press release)

A new study highlights the importance of the Earth's nitrogen cycle and its link to the global carbon cycle, especially the concentration of CO2. (University of Miami Rosenstiel School of Marine & Atmospheric Science press release)

Last summer scientists published research concluding that geological faults in the Sichuan Basin, China "are sufficiently long to sustain a strong ground-shaking earthquake, making them potentially serious sources of regional seismic hazard." (British Geological Survey press release)

As much as a third of the nitrogen entering the world's oceans from the atmosphere is man-made, according to new findings by an international team of scientists. (University of East Anglia press release)

A large quantity of nitrogen compounds emitted into the atmosphere by humans through the burning of fossil fuels and the use of nitrogen fertilizers enters the oceans and may lead to the removal of some carbon dioxide from the atmosphere. (Texas A&M University press release)
