El Niño Begins to Dissipate
Though weak El Niño conditions still exist, it appears that the climatic phenomenon that developed over the course of last summer has finally begun to dissipate. As reported earlier, El Niño is the name given to sustained sea surface temperature (SST) anomalies greater than 0.5°C across the central tropical Pacific Ocean. It is the warm…

Wally Broecker: 50 Years of Climate Science Innovation
Since arriving at Lamont-Doherty Earth Observatory in 1952, for a college summer internship, Wally Broecker has come up with some of the most important ideas in modern climate science. He was one of the first researchers to recognize the potential for human-influenced climate change, and to testify before Congress about its dangers. He helped pioneer…

Studying the Impacts of Climate on High-Altitude Ecosystems
Columbia University researchers Laia Andreu Hayles and Daniel Ruiz Carrascal traveled to Colombia last month to investigate the impact of climate on high-altitude ecosystems in the Andes. Supported by the Lamont-Doherty Earth Observatory Climate Center, Andreu and Ruiz are exploring the potential of several high-altitude tree species to reveal information about past climate variability and…

Looking Back on Winter: Part I
The arrival of spring in temperate climates means more hours of daylight, showers and flowers. Despite the general mood improvement from the dark days of winter, we should not be quick to forget the controversies surrounding this past season. Winter 2010, deemed by media outlets as Snowmaggedon and Snowpocalypse, was the snowiest season on record…

Urbanization, Deforestation, Reforestation
2009 was noted as the first year that more people lived in urban spaces than in rural areas. The hope that a majority urban population would slow the clearing of tropical forests — our most effective carbon sinks — seems, however, to have been misplaced. The idea was simple: if more people moved into forested…

Is there hope from Copenhagen?
Can we find positives from the United Nations Summit on climate change? Even President Obama admits that disappointment is justified, although the Commander in Chief claims a non-binding accord was better than a complete collapse of the negotiations. Jeffrey Sachs, fearless leader of the Earth Institute, adamantly opposed such victory proclamation from the President, for…

The State of the Arctic
Where climate change is concerned, the Arctic region acts as a harbinger: the extremely sensitive Arctic system reacts earlier and more profoundly to anthropogenic climate change than many other regions. And as climate change progresses, it is also projected to experience greater environmental changes than other places on earth. As such, it has become an…
