Human-Influenced Climate Change May Have Contributed to Society’s Collapse

Over the past 450 million years, life on earth has undergone at least five great extinctions, when biological activity nosedived and dominant groups of creatures disappeared. The final one (so far) was 65 million years ago, when it appears that a giant meteorite brought fires, shock waves and tsunamis, then drastically altered the climate. That killed off…

Wave-washed sea cliffs along the coasts of western England and Wales are home to spectacular assemblages of rocks and fossils that may hold keys to understanding a sudden global extinction 201.4 million years ago that cleared the way for the rapid evolution of dinosaurs. Paleontologist Paul Olsen and geologist Dennis Kent of Columbia University’s Lamont-Doherty…

Paleontologist Paul Olsen has been investigating the causes of Triassic-Jurassic extinction–a turning point in earth’s history that wiped out many life forms and started the reign of dinosaurs. More than 200 million years separate us from this catastrophe (also called the End-Triassic Extinction), but it could contain some lessons for us today, says Olsen. For…

One hour from New York City, where the suburbs of New Jersey give way to farms, a team of scientists are drilling for ancient rocks on the edge of a cornfield. The rocks hold clues about what the earth was like about 201 million years ago,during the great extinction that allowed dinosaurs to dominate. Listen…

The Columbia Climate Center led PoLAR Climate Change Education Partnership receives a $5.6 million grant from the National Science Foundation (NSF), one of six awards under the Climate Change Education Partnership-Phase II program.

The worst drought to hit the U.S. in decades has already brought corn yields to a 17-year low and will almost certainly raise food prices. Wealth will soften the blow in the U.S., but in sub-Saharan Africa and South Asia, prolonged drought has often had deadly consequences. Is there a better way to anticipate climate’s…

The Intergovernmental Panel on Climate Change projects that droughts will likely increase in central North America this century. How can we prepare for a future of perpetual drought?

On Wednesday, August 8, students in the Master of Science in Sustainability Management program presented their final Capstone Workshop presentations for fellow students, program faculty, and colleagues at Columbia University’s Faculty House. The project, entitled “Environmental Performance Reporting,” required the team to analyze the pros and cons of the most viable reporting systems in order…
