Greenland’s fjords are far deeper than previously thought, and glaciers will melt faster, researchers find
West Greenland’s fjords are vastly deeper than rudimentary models have shown, allowing intruding ocean water to badly undercut glacier faces, which will raise sea levels around the world much faster than previously estimated. Those are the findings of a University of California-Irvine-led research team that battled rough waters and an onslaught of icebergs for three summers to map the remote channels for the first time.

A new study shows that Beijing quadrupled in physical extent between 2000 and 2009. The new buildings alone — not including the impacts of additional city dwellers and their cars — increased heat and changed wind and pollution patterns in a ring around Beijing.

Our sun is a volatile star: explosions of light, energy and solar materials regularly dot its surface. Sometimes an eruption is so large it hurls magnetized material into space, sending out clouds that can pass by Earth’s own magnetic fields, where the interactions can affect electronics on satellites, GPS communications or even utility grids on the ground.

The Grand Canyon is a bit closer to how it was before one of the country’s largest dams was installed upstream. Three years of releasing water from Glen Canyon Dam to generate controlled floods has resulted in rebuilding sandbars in the Grand Canyon, according to a new USGS article published in Eos, the daily Earth and space science website published by the American Geophysical Union. These simulated floods redistribute sand and mud, which helps develop this critical feature.

Waves in the northern Gulf of Mexico are higher than they were 30 years ago, contributing to a greater risk of coastal erosion and flooding in Florida, Alabama, Mississippi and Louisiana, according to a new study.

For the last nine years the United States has dodged the hurricane bullet: No major tropical cyclones have made U.S. landfall. Such a remarkable “hurricane drought” has never been seen before – since records began in 1851. It beats the previous record of eight years from 1861-1868, say researchers who have looked into the probabilities of the unusual streak, what it means for the chances of hurricanes this year and whether or not insurance premiums reflect the risks. Their conclusion: the hurricane drought is mostly a matter of dumb luck.

New research matching different types of underwater volcanic eruptions with their unique sound signatures could help scientists better detect and understand emissions occurring on the seafloor.

Torrential rains inside hurricanes might be acting as a control knob on these giant storms, reducing their intensity by as much as 30 percent, according to a new study.

On Dec. 19, 2006, the sun ejected a small, slow-moving puff of solar material. Four days later, this sluggish Coronal Mass Ejection was nevertheless powerful enough to rip away dramatic amounts of oxygen out of Venus’ atmosphere and send it out into space, where it was lost forever. Learning just why a small CME had such a strong impact may have profound consequences for understanding what makes a planet hospitable for life.
