Shrinking Glaciers: A Chronology of Climate Change
During the last ice age, glaciers dominated New Zealand’s Southern Alps until warming temperatures some 20,000 years ago sent them into retreat. Scientists at Lamont-Doherty Earth Observatory, with their colleagues, are investigating the rocky remnants these glaciers left behind to learn precisely when the ice withdrew, and what glacier retreats globally can tell us about…

Chasing Ghengis Khan
Once you, as an outsider, spend considerable time in Mongolia, especially during Naadam and especially in the open Gobi steppe with people who still live as their ancestors did centuries ago, you will also begin to chase Chinggis Khaan.

Water Samples and Wildlife
After a day of coring on Tuesday, we decided to give our arms and backs a rest and collect water and plant samples. We take these samples so that we can characterize the chemical signatures of each plant type, and water from different parts of the system. Then, we can recognize those same signatures in…

Taking Steps (Together) in the Right Direction
The latest 2012 Climate Change Policy Tracker report released by Deutsche Bank Climate Change Advisors in partnership with the Columbia Climate Center shows that while current policies lead to emissions reductions, there is significant distance to go to reach “safe” levels of atmospheric greenhouse gases by 2020.

Deepest core yet from Imnavait Creek!
Our first day in the field was a wild success! We visited Imnavait Creek Peatland, named for the small stream that drains out of it into the Kuparuk River. We chose this location because it has the potential to be much older than many other peatland sites. During the last ice age, the area of the…

Getting There = 0.5*fun
Hello from the land of the midnight sun! We have just arrived by way of the famous Dalton Highway at Toolik Field Station, a Long Term Ecological Research site of the University of Alaska Fairbanks. We pulled up to the station just in time for dinner, a quick trip to the field station’s wood-fired sauna,…

A Major Legal Victory for Climate Science
Though most attention last week focused on the Supreme Court ruling upholding federal reform of the health-care system, the U.S. Court of Appeals for the District of Columbia issued the most important judicial decision on climate change in five years. That decision upholds the Environmental Protection Agency’s power to regulate greenhouse gases, and it…

Studying Cutting-Edge Carbon Storage Technologies
This past June, PhD candidates from Earth Institute’s Lenfest Center for Sustainable Energy Miriam Okun and Yinghuang Ji traveled to Alabama to attend Research Experience in Carbon Sequestration (RECS), an intensive 10-day program hosted by Southern Company and sponsored by the Department of Energy’s National Energy Technology Laboratory. The program allowed participants to study cutting-edge…
