The Compact Efficiency of New Airborne Science
The latest team celebration is around the magnetometer data. Magnetics has evolved quite a bit over the years of geophysical sampling. Lamont scientist Robin Bell recalls when in the 1990s working on a project in West Antarctica that the magnetometer was towed on a winch ~100 meters behind the aircraft – now it is nearly…

Photo Essay: Land, Lava, People
On Hawaii, lava is a way of life. The whole island is made of the stuff. Eruptions from Kilauea volcano have been adding new land and wiping out old for all of human time, and far before. In recent decades, lava flows have wiped out communities and major roads. The latest eruption, which began in June 2014, now…

In Hawaii, Living With Lava
When the most recent eruption of Hawaii’s Kilauea volcano started last June, Melvin Sugimoto at first did not think much of it. Hawaii, where he has lived all his life, is made entirely of hardened lava, and Kilauea, perhaps the world’s most active volcano, has been adding more off and on for the last 300,000 years. “Lava is…

Exploring Beneath Earth’s Changing Ice Sheets
If just the West Antarctic Ice Sheet were to melt, it would raise global sea level by 6 meters. That’s more than a theoretical problem. West Antarctica is losing ice mass, and scientists are worried.

Earth’s Magnetic Field: Just Returning to Normal?
Earth’s magnetic field is getting weaker, but it may simply be coming down from an abnormally high intensity rather than being a sign of an impending geomagnetic reversal.

Climate Is Changing Fast in West Antarctica
Fast-rising temperatures on the Antarctic Peninsula are having an impact on the ice and marine life, and providing clues about future ecosystem changes elsewhere.

In One Simple Line of Data You Can Read a Full Story
The lines of data are slowly creeping across our Ross Ice Shelf GIS map and with each new line comes an improved understanding of Ross Ice Shelf. What can you learn from a ‘snapshot’ of data? A radar contains a nice story.

Peat Fires Choking Southeast Asia Pose a New Threat to Global Climate
The Indonesian peat fires that have been choking cities across Southeast Asia with a yellow haze are creating more than a local menace—burning peat releases immense stores of CO2, contributing to global warming.
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“
