A power plant in Iceland is set to become the first in the world to try turning carbon dioxide emissions into solid minerals underground, starting this September.
In an $11 million pilot project, Reykjavik Energy will capture CO2 from its plant, dissolve the gas in water and inject it deep into volcanic basalt nearby. Over the nine-month study, some 2,000 tons of greenhouse gas will be treated.

Seismologists, Pinpointing Location, See Little Doubt It Was Bomb
Seismologists who have intensively studied North Korea’s nuclear testing efforts say Monday’s blast was certainly a nuclear bomb, roughly five times larger than the country’s first test in 2006.

Another world lies beneath the Hudson River, as scientists have shown using pulses of sound to map the bottom. In recent years, the bathymetry maps developed at Lamont-Doherty Earth Observatory and Stony Brook University have turned up hundreds of shipwrecks and a new channel off Battery Park City, drawing interest from treasure hunters and mariners alike. Now a new group is finding inspiration: artists.

The new Gary C. Comer Geochemistry Building at Columbia University's Lamont-Doherty Earth Observatory in Palisades, N.Y., has won three top architecture awards. Recognized for its environment-friendly features, the building houses more than 80 staff, many of whom have long been at the forefront of global climate research. Scientists in Lamont's geochemistry division study the movements and interactions of substances in air, oceans, groundwater, biological remains, sediments and rocks.

Landslides kill thousands of people each year but because they're often triggered by earthquakes or heavy rains, the danger remains poorly understood. A PhD candidate at Lamont-Doherty Earth Observatory has put together a global catalog of recent mudslides to help scientists better predict where and when the next one will occur.

Even on a sunny day, nearly 13 million gallons of water are pumped from New York City subways. As global warming brings rising sea levels and more frequent storms, more of New York’s transit system is expected to flood.

New Dating Technique Points to Differences Over 7,000 Years
The vast majority of the world’s glaciers are retreating as the planet gets warmer. But a few, including ones south of the equator, in South America and New Zealand, are inching forward. A new study in the journal Science puts this enigma in perspective.

A new book, Climate Change: the Science of Global Warming and Our Energy Future, serves as an excellent, long-needed primer on the workings of earth's climate.

Global Warming Could Worsen Newly Seen Pattern
Researchers have developed the first year-by-year record of rainfall in sub-Saharan West Africa for the past 3,000 years, and identified a daunting pattern: a 30-to-60-year cycle of serious droughts that last a decade or more, punctuated by killer megadroughts that last for centuries.

Oceanographer Wins Prestigious Prize for Work Advancing Education
Kim Kastens, an oceanographer at Lamont-Doherty Earth Observatory, has been recognized for her research in making spatial concepts in earth science easier for students in a wide age range to understand. She will receive the American Geophysical Union’s Excellence in Geophysical Education Award at a ceremony in Toronto in May.

Four current and former researchers at Lamont-Doherty Earth Observatory will receive honorary degrees from their alma mater, St. Lawrence University, this spring. The degrees will be awarded at May graduation to paleoclimatologist Peter deMenocal; engineer Dale Chayes; paleoceanographer Miriam Katz; and oceanographer Richard Fairbanks.

Iran seems to be moving toward an atomic bomb; North Korea reportedly could build a half dozen; and terrorist attacks have revived the specter of a faceoff between nuclear-armed Pakistan and India. Yet the Comprehensive Test Ban Treaty, forbidding nuclear testing, has failed to win ratification from the U.S. Senate and lawmakers of some other nations. Opponents say scientists cannot reliably detect clandestine tests: Why should we go along, if others can cheat?
