Expanding Our Vision Brings the Big Picture Into Focus
1500 feet above the ground surface is where our suite of instruments normally operates, but for this flight we are taking them up higher, much higher, in fact over 20 times our normal range to 33,000 feet. Our flight plan is to repeat lines surveyed in a previous years by NASA’s Land, Vegetation Ice Sensor…

Next, Imbabura
Today was a much longer climb up Imbabura, passing through more páramo until reaching our first Polylepis trees. Conveniently, they were marked by a little wooden sign. These are the trees that I hope to sample next week on Chimborazo.

Climbing Fuya Fuya
After trudging through the paramo, our route becomes a high-altitude scramble on an exposed rocky granite spine with sheer drop-offs on either side. The surge of adrenaline keeps our minds off the thin air.

I am here to collect tree ring samples and put up a weather station on Chimborazo, Ecuador’s tallest peak, to provide climate data about this region, which…

‘This is a wake-up call – don’t hit the snooze button’
For years before Hurricane Sandy charged ashore on Monday, researchers from the Earth Institute knew what was coming. As the region struggles to recover from this “superstorm,” we asked some of them to consider the lessons we can learn as we move forward.

A Prescient Voice on Sandy: Suddenly Everyone Is Listening
For much of the last decade, Klaus Jacob warned of New York’s vulnerability to severe flooding in a major storm. Four days after the storm that crippled New York and New Jersey and swamped his own home along the Hudson River, Jacob reflected on Sandy’s lessons and what comes next.

The Zen of Sanding
By Ana Camila Gonzalez “But can’t you see the rings already?” I ask, wondering why I’ve been asked to sand a sample- it sounds to me like one would damage a sample by subjecting it to the mechanical screech of a sander. “Yes, but under the microscope they look foggy if you don’t sand…

The ‘Skinny’ on Antarctic Sea Ice
One piece of our IceBridge mission focuses on sea ice here in the south. Sea ice in the northern regions has been reducing at dramatic rates over the last decade, setting a new record just this year, but the story in the south is not so clear. In fact, there has been a buzz that…
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“
