Annual tree rings are a rare find in the tropical islands of the eastern Pacific. The new discovery of trees with annual rings on a Hawaiian volcano could provide new climate data from a part of the world where much of the variability of the El Niño-Southern Oscillation originates.
The U.S. Gulf Coast has already felt the lasting effects of extreme weather on public health and infrastructure, and a new study says things could get worse with climate change.
The Columbia Center on Sustainable Investment, a joint center of Columbia Law School and the Earth Institute, is seeking an administrative assistant intern for Fall 2015.
“It took taking the Intro to Sustainable Development class for me to understand that this major is not only immediately applicable and vitally important, but also varied and interesting enough to keep me engaged throughout my college experience. Put simply, I discovered the passion that I hadn’t realized was there all along.”
Understanding how coastal areas changed as the ocean rose in the past could help communities protect themselves from storm surge flooding in the future as the oceans warm and sea levels rise.
The land surrounding the Arctic Ocean is like a set of cradling arms, holding the ocean and the sea ice in a circular grasp. Within that cradle is a unique mix of waters, including freshwater from melting glacial ice and large rivers, and a salty mix of relatively warm Atlantic water and the cooler Pacific water.
In the islands off Papua New Guinea, the rocks are giving rise to new ideas about the ways mountain chains form. A new scientific model shows how two seemingly opposite processes can take place in the same region.
“My experience at Lamont has been great and it’s something like no other. Here I was basically being trained to be like a scientist with exposure to lab work, fieldwork and presentation skills.”
Researchers from eight universities, including Columbia University, are using tree ring and glacier analysis to reconstruct the climate history of the Missouri River Basin in order to give policymakers and water managers better decision-making tools to manage the river.
