Antarctica's Southern Ocean May No Longer Help Delay Global Warming

Researchers are studying the ocean's carbon dynamics to improve predictions for sea level and temperature rise. “New technologies are allowing us access to these remote areas, and we are far less dependent on driving a ship through the sea ice," Lamont oceanographer Arnold Gordon told Nature magazine.

How Did Climate and Humans Respond to Past Volcanic Eruptions?

To predict and prepare for future climate change, scientists are striving to understand how global-scale climatic change manifests itself on regional scales and also how societies adapt—or don’t—to sometimes subtle and complex climatic changes.These issues were at the heart of the inaugural workshop of the Volcanic Impacts on Climate and Society (VICS) Working Group, convened at Lamont-Doherty Earth Observatory.

Recently Killed Elephants Are Fueling the Ivory Trade

The illegal trade in elephant ivory is being fueled almost entirely by recently killed African elephants, not by tusks leaked from old government stockpiles, as had long been suspected. That’s the conclusion of a new study from Lamont's Kevin Uno that relies on nuclear bomb tests carried out in the 1950s and ’60s to date elephant tusks.
