A Controversy: Fracturing in the Marcellus Shale
The organic-rich source rock of the Marcellus Shale is an on-going target for massive gas extraction. Advances in horizontal drilling and hydraulic fracturing, or hydrofracking, have made this extensive area of Marcellus black shale one of the largest unconventional and widely controversial gas operations in the United States today.

Plugging the Leaks in Climate Models
Independent quality controls for climate models are crucial for the quality of future climate change predictions. Not all models are equally good and should be utilized in climate impact studies for such things as crop yield and hydrology that are produced for far-reaching decision-making.

Climate change may be affecting the jet stream
A new study provides evidence that climate change may be affecting the northern hemisphere jet stream, which appears to be moving north and slowing down. The slowing of the jet stream could cause weather patterns to remain in place for longer, resulting in prolonged heat waves or cold snaps.

Watch an Antarctic Iceberg in the Making
What does a glacier about to spawn an iceberg the size of New York City look like? A new animation from NASA flies you through the 19-mile crack that is slowly tearing Antarctica’s Pine Island Glacier apart.

What Darwin Saw
Sir Charles Darwin realized that humanity is interwoven with nature, that all of life is in a state of constant flux. The empowerment of nature, made possible by Darwin’s integration of human life into the whole, and grounded in his lived experience and profound humility, is the foundation of modern ecology.

Biodiversity in the Shawangunk Mountains
Recently ranked highest in biological diversity and as one of the “last great places on Earth”, the Shawangunk Mountains are being actively reintroduced to forest fires in an attempt to preserve biodiversity.

Seeking the Signal in the Noise of Environmental Performance Metrics
The 2012 Environmental Performance Index is a powerful tool for diagnosing trends not just across countries but over time, too. Consider what we can learn about overfishing, for example.
AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
