    Internships Available at Center on Sustainable Investment

    The Columbia Center on Sustainable Investment is accepting applications until March 31 for internship positions for summer 2016. Interns are assigned to one or more projects depending on background and interests; unpaid and paid opportunities are available.

  • The Sustainable City

    By concentrating human population in cities, we will make it possible to preserve land for wilderness, ecosystem maintenance and agriculture. People will travel to these places and will experience nature, but only a fortunate few will live close to nature.

    Uncovering Impacts of Gold Mining in Papua New Guinea

    From late December 2015 through January, a team of Earth Institute scientists and human rights lawyers from Columbia University worked in the highlands of Papua New Guinea to deliver the results of an independent study of water quality and human rights to the indigenous communities living near an industrial gold mine.

  • A Sustainable Lifestyle and the Changing Nature of Work

    In the process of changing the economic role of the city, we need to pay more attention to the impact of our production and consumption on the environment and on all elements of the supply chain that bring goods and services to us. Building systems that reduce environmental impacts is more important than individual consumption…

    Six Tough Questions About Climate Change

    People often ask certain tough questions about climate change— about the costs of cutting carbon emissions, the feasibility of transitioning to renewable energy, and whether it’s already too late to do anything about climate change. Laura Segafredo, manager of the Deep Decarbonization Pathways Project, answers these questions.

    From Copenhagen to Paris: Getting Beyond Talk

    The climate issue seems to generate a high level of ideologically based politics, emotional rhetoric and political symbolism. It is time to move past symbols to pragmatism and political reality.

  • Getting Sustainability on the Agenda of Our Dysfunctional Federal Government

    What is needed politically and in reality is a positive vision of a sustainable society. In the case of this country it will need to be built on the traditional values that have always attracted people to America: freedom, rewarding individual achievement, a love of the new and novel, innovation, and acceptance (even if reluctantly)…

    Last Sample and Home

    We finished our work at the river transect. Now we had one more sample to collect. Alamgir had arranged for drillers at this new site, but they were delayed because of a knife fight between two villages over some property.

  • OSL Samples at Last

    OSL Samples at Last

    The success of the tube wells for drilling and obtaining samples was a great boon to our field program. We drilled three additional tube wells to complete a five-well transect across the abandoned river valley. When we date the samples, we will find out if the river switched position suddenly, possibly from an earthquake.

AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
