With life, legged and finned, Earth had been teeming,
Slitherers, predators, graceful trees tall …
Now, of these species, we are only dreaming:
Glossopteris, trilobites, eurypterids, all.
Carbon capture, storage and reuse has the potential to help us reduce CO2 emissions and combat global warming. The Lenfest Center for Sustainable Energy is bringing together experts from an array of fields to assess the state of the technology April 14-16.
The Earth Institute, Columbia University is proud to support student research in the areas of environment and sustainable development at the annual Student Research Showcase on April 25, 2014. Student interns, research assistants and travel grant recipients, and their Faculty and Research Advisors, will be honored for their research contributions that ranged in topics from biodiversity, urban planning, earth sciences to international development.
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.
Humans hate to catch the flu,
But here’s a fact that’s less well-known:
Bacteria get infections too
As many cultures have now shown.
Gliders and buoys and robots — oh my!
Over and through the ocean they fly.
Oodles of data from sensors galore,
Studied by many, far from the sea’s roar.
An ancient grain of zircon found
In Jack Hill sandstone north of Perth,
Inside its crystal lattice bound:
Secrets of our planet’s birth.
Bess Koffman, a postdoctoral researcher at Lamont-Doherty Earth Observatory, recently traveled to New Zealand to collect dust ground-up by glaciers during the last ice age. In this photo essay, she explains how she collected the dust, what analysis looks like in the lab and what she hopes to learn.
Forests are a vitally important habitat for much of the world’s terrestrial biodiversity. During this class you will learn key issues in forest ecology and management through an all-day field trip to Black Rock Forest, and study how pathogens and other invasive species affect forest structure and function.
