    Tree Rings and Teachable Moments

    Nicole Davi, a postdoctoral scientist at the International Research Institute for Climate and Society and the Lamont Doherty Earth Observatory, thinks tree rings are an ideal way to motivate students to collect and analyze data as well as to learn about climate change.

    Glenn Denning’s Road to Bali, and the Earth Institute

    Glenn Denning grew up in Brisbane, Australia, loved the outdoors and hated the idea of working in an office. And, he really didn’t have any urge to go to other countries. Then he happened to overhear a conversation in a hallway between two students. That bit of serendipity sent him on a road to a…

    Next, Imbabura

    Today was a much longer climb up Imbabura, passing through more páramo until reaching our first Polylepis trees. Conveniently, they were marked by a little wooden sign. These are the trees that I hope to sample next week on Chimborazo.

    Preparing for Chimborazo

    I am staying with a friend’s family in Quito, Ecuador’s capital city, and tomorrow will meet up with my climbing partner, Pablo Puruncajas, to prepare for our expedition. I am here to collect tree ring samples and put up a weather station on Chimborazo, Ecuador’s tallest peak, to provide climate data about this region, which…

    The Missing Piece in Sustainable Peace

    We know very little about what “peace” is (and what it isn’t), the conditions that promote it, the motives that drive people to work for it, how to measure it, and how to build a climate and infrastructure that sustains it.

    “Field Trip: A Climate Cabaret,” at the Lamont Doherty Earth Observatory Open House on Oct. 6, will use song and dance to focus on the research of prominent female scientists.

  • Practicum Introduces Students to Earth Institute Research

    Each fall the Earth Institute offers a unique insight into the cutting-edge research of institute centers and units and the policy implications of that research in the Earth Institute Practicum. The practicum provides an opportunity to learn about issues in sustainable development, sustainability management and environmental science from faculty and researchers in these areas.
