Photo Essay: Sleeping Giant off West Africa Awakes
Nearly 20 years after its last eruption, in 1995, Fogo volcano off West Africa awoke on Nov. 26. Within a week, it had buried two villages under scorching lava, leaving 1,200 people homeless. Lamont-Doherty geologist Ricardo Ramalho was there to document the action and help advise local government.

Ice Loss in West Antarctic is Speeding Up
Glaciers in one part of West Antarctica are melting at triple the rate of a decade ago and have become the most significant contributor to sea level rise in that region, a new study says. The study found that the glaciers in the Amundsen Sea Embayment of West Antarctica have shrunk by an average of…

A Texas-Sized Block of Ice…
The Ross Ice Shelf is the largest of the Antarctic ice shelves, measuring just under the size of the state of Texas. It is several hundred meters thick, although most of this is below the water surface. Along the ~ 600 kilometer front edge of the shelf, the ice towers up to 50 meters in…

Why are Past Surface Temperatures and CO2 Concentrations Important?
By burning fossil fuels for heating, electricity, transportation and other purposes, humans add CO2 to the atmosphere. Yet, by comparing ways in which the Earth’s temperature, CO2 concentration, sea level and ice sheets have changed in the past, we are able to learn valuable lessons about the climate system of today and tomorrow.

This Bird Flies South for the Winter
Migrating south in the winter is a behavior that Antarctic scientists share with many species of birds, although the scientists fly just a bit further south. For the IcePod team it was time to join the migration so they could test their equipment in the most challenging environment the Earth has to offer.

Sounds of Seismology
Lamont-Doherty Earth Observatory scientist Ben Holtzman grew up discovering science through interactive exhibits in San Francisco’s Exploratorium and now provides a similar experience for others. Holtzman designs immersive shows that allow people to experience what earthquakes and seismic waves look and sound like as they move through and around the Earth. On Monday, November 17th…

Study: NASA Sites Vulnerable to Climate Change
NASA has been at the forefront of climate science, launching satellites that take the pulse of Earth’s land, oceans and atmospheric systems. But the agency is increasingly vulnerable itself to the effects of a changing climate.
By studying thousands of buildings and analyzing their electricity use, Columbia Climate School Dean Alexis Abramson has been able to uncover ways to significantly cut energy consumption and emissions. Watch the Video: “Engineering a Cooler Future Through Smarter Buildings“
