On Our Way: Avoiding the Storm
We are now aboard the R/V Palmer and on our way to East Antarctica. Due to two storms in our direct way we are heading west first to go around the storms and we’ll then head south on their backside.

Photo Essay: Sculpting Tropical Peaks
Max Cunningham, a graduate student at Lamont-Doherty, traveled to Costa Rica’s Mount Chirripó this past summer to test the idea that mountain glaciers carved the summit we see today. He and his colleagues hope to eventually pin down when Chirripó’s high-elevation valleys eroded into their current form. Check out a recap of their 2014 field…

Is the Highest Climb Sustainable, and Who Pays the Price?
The Khumbu Icefall on Mount Everest is perhaps the most well-known and notoriously dangerous glacial feature on the planet. In a fresh post on the Glacier Hub blog, the Earth Institute’s Ben Orlove, writing with anthropologist Pasang Yangjee Sherpa of Penn State, recounts a recent workshop held in Kathmandu to address the issues raised by…

Beneath an Icelandic Glacier, Another Eruption Brewing
The 2,000-meter tall Bárðarbunga volcano in Iceland is at risk of eruption, an event that could send a cloud of ash and steam high into the atmosphere and cause extensive disruptions in air travel, among other effects, according to media reports. Earth Institute scientist Ben Orlove looks into it on the Glacier Hub blog.

What Geology Has to Say About Global Warming
The most important lessons drawn from geology are that the earth’s climate can change radically, and rapidly. We can’t say precisely at what CO2 level we’re in danger of melting Antarctica, but that threshold could be reached in 150-300 years, if CO2 levels keep rising at the current rate.

Clock Is Ticking in West Antarctic
“The high-resolution records that we’re getting and the high-resolution models we’re able to make now are sort of moving the questions a little bit closer into human, understandable time frames.”

Celebrate Earth Day with Extreme Science
Lamont-Doherty Earth Observatory scientist Robin Bell will participate in a Google+ Hangout hosted by the White House on Tuesday, April 22 at 4:00 p.m. EDT. Bell, who will join the Hangout from New Zealand, is a polar scientist who studies sub-glacial lakes, ice sheet dynamics and tectonics in Earth’s polar regions.

Joanne Johnson and Lamont-Doherty, Collaborating on Glacial Research
New research about West Antarctica’s Pine Island Glacier suggests the glacier’s recent and rapid thinning and melting may continue for decades or centuries to come. British Antarctic Survey’s Joanne Johnson’s research, done in collaboration with scientists at Lamont-Doherty, might not have been possible without Lamont’s effort to promote women scientists.

When the World Ended in Ice
A mile or so of glacial ice covering much of North America and plowing down from the north once terminated in the New York metropolitan area, at a front stretching roughly from exit 13 on the New Jersey Turnpike (Rahway), on across southern Staten Island, the Bensonhurst neighborhood of Brooklyn, and northeastward through Long Island. But exactly when that ice started…
