Greenland Once Lost Nearly All Its Ice and Could Again - Scientific American

Wed, 12/07/2016 - 15:26
Evidence buried in Greenland's bedrock shows the island's massive ice sheet melted nearly completely at least once in the last 2.6 million years. The findings from a study led by Lamont's Joerg Schaefer suggest that Greenland's ice may be less stable than previously believed.

Retreat of Antarctica's Pine Island Glacier Began Around 1940s - Space Daily

Fri, 11/25/2016 - 12:00
New research by an international team, including scientists from Lamont-Doherty Earth Observatory, shows that the present thinning and retreat of Pine Island Glacier in West Antarctica is part of a climatically forced trend that was triggered around the 1940s. Even when climate forcing weakened, ice-sheet retreat continued, the scientists found.

Recently Killed Elephants Are Fueling the Ivory Trade - Science Magazine

Mon, 11/07/2016 - 12:00
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.
