China Burns up the Clean Energy Race
Although China dominates in the race to be the leading global manufacturer of clean renewable energy, they are not necessarily doing the most for the environment. China, consistently pushing the clean energy market towards an economic future, was expected to be a leading developing country in negotiations at Rio+20. Meanwhile, the United States, without a…

Investigating Impacts of Increased Fertilizer Use in Africa
The rains came late this year in Kenya. I was there for several months in the winter and spring to conduct research for a post-doctoral fellowship, examining the consequences of increases in fertilizer use on soil fertility, maize yields, nitrogen gas emissions and nitrogen leaching losses.

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…
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“
