The creation of the narrow isthmus that joins North and South America changed not just the world map, but the circulation of oceans, the course of biologic evolution, and probably global climate. Scientists try to decipher the story behind its formation.
The formation of the slender land bridge that joins South America and North America was a pivotal event in earth’s history. At its narrowest along the isthmus of Panama, it changed not just the world map, but the circulation of oceans, the course of biologic evolution, and global climate. Cornelia Class, a geochemist at Columbia University’s Lamont-Doherty Earth Observatory, and Esteban Gazel, a Lamont adjunct researcher now based at Virginia Tech, are looking into a key factor: the Galápagos Plume.
As the arctic region loses ice in a changing climate, the economic and social tradeoffs are unclear. How will we balance economic, social and environmental functions? The Center on Global Energy Policy and the Consulate General of Canada in New York will examine these questions in a discussion on March 26: “Understanding the Arctic Resource Challenge: Canada and U.S. Perspectives.”
Earth Institute field researchers study the planet on every continent and ocean. Projects are aimed at understanding the fundamental dynamics of climate, geology, ecology, human history and more. Here is a partial list of upcoming expeditions.
The Earth Institute is grateful to its many partners for their important role in the effort to develop the science and solutions necessary for sustainable development. Please visit the interactive digital 2013 Annual Report to read more about how we are forging partnerships across disciplines and sectors to advance the global effort to guide our planet onto a path toward sustainability.
In late 2013, the dream of creating a uniquely powerful facility for the Lamont-Doherty Geochemistry Division became a reality upon completion of the Comer Building’s Ultra Clean Laboratory. On the afternoon of November 20th, this new laboratory was dedicated in front of an audience of Observatory Advisory Board members, donors, scientists and other members of the extended Lamont-Doherty and Columbia University communities.
Scientists from Columbia University’s Earth Institute will present important research results and special events at the Dec. 9-13 San Francisco meeting of the American Geophysical Union, the world’s largest gathering of earth and space scientists. Here is a guide in rough chronological order.
Four scientists and one PhD student from the International Research Institute for Climate and Society are attending the 2013 American Geophysical Union’s Fall Meeting. Below are links to Q&As with each of the presenters and the schedule of their posters and presentations.
The spectacular colors of fall foliage draw throngs of tourists to the Eastern U.S. each year. However, new research from The Chinese Academy of Sciences suggests that climate change may shift the timing of this seasonal event to the detriment of travelers and locals alike.
