Clues from Last Ice Age May Hint at Drying Ahead for Some Regions

In the spectacular collapse of ice sheets as the last ice age ended about 18,000 years ago scientists hope to find clues for what regions may grow drier from human caused global warming. In a talk Thursday at the American Geophysical Union’s annual meeting, Aaron Putnam, a postdoctoral scholar at Lamont-Doherty Earth Observatory, painted a…
Huge Landslide Linked to Glacier Surge in Tajikstan’s Pamir Mountains

Glaciers advance in colder temperatures, but sometimes a big rock avalanche can also make a glacier grow, new research results presented at the American Geophysical Union’s annual meeting suggests.
Frozen Water on Mercury, NASA Confirms

Mercury, the planet closest to the Sun, may hold at least 100 billion tons of ice in permanently shaded craters near its north pole, NASA scientists announced Thursday. The findings come as NASA’s MESSENGER spacecraft nears its second year of orbit around Mercury. MESSENGER’s lead investigator, Sean Solomon, is director of Columbia University’s Lamont-Doherty Earth…
After Sandy, Testing the Waters

During Hurricane Sandy the seas rose a record 14-feet in lower Manhattan. Water flooded city streets, subways, tunnels and even sewage treatment plants. It is unclear how much sewage may have been released as plants lost power or were forced to divert untreated wastewater into the Hudson River. Four days after Sandy, the environmental group…
A Prescient Voice on Sandy: Suddenly Everyone Is Listening

For much of the last decade, Klaus Jacob warned of New York’s vulnerability to severe flooding in a major storm. Four days after the storm that crippled New York and New Jersey and swamped his own home along the Hudson River, Jacob reflected on Sandy’s lessons and what comes next.
A Talk with Sean Solomon, Lamont-Doherty’s New Director

“The Observatory has remained a powerhouse in Earth science research and a very special place. The scientists here are true explorers—creative and fiercely independent.”
Newtown Creek Clean-Up Polluting the Air, Researchers Say

A city effort to clean-up polluted Newtown Creek by aerating the water to boost oxygen levels is having an unintended effect: it is releasing sewage bacteria and other particles into the air above the site, researchers say in a new study in the journal Environmental Science and Technology. The researchers found bacteria types in the…
Master of It All: One Woman Scientist Pays Tribute to Another

Lamont-Doherty geophysicist Robin Bell pays tribute to colleague Kim Kastens who is retiring from Lamont after 31 years. Kastens was the first woman co-chief scientist on the JOIDES Resolution, first woman faculty member to join Columbia’s geology department, founder of Columbia’s joint journalism and environmental science master’s program and a pioneer in the field of…
What’s Holding Water Conservation Back in Rockland County?

Rockland County’s main water provider, United Water NY, wants to build a treatment plant on the Hudson River that would deliver more freshwater to Rockland taps. As the project awaits state approval, a new debate on water consumption has emerged. Should people be encouraged, or even required, to use less? And if so, how?
