    Changing Ocean Chemistry: the Poem

    A study published earlier this month indicated that due to manmade emissions of carbon dioxide, the earth’s oceans are tipping toward acidity faster than at any time in the last 300 million years. It made world headlines, and this week the study was the subject of Sunday New York Times editorial, “Changing the Chemistry of Earth’s Oceans.” And now, the poem.…

    At the Bottom of the Bottom of the World

    As we in North America emerge from a remarkably mild winter, the brief and sunny summer in the world’s deep south is drawing to a rapid close. Antarctica’s days are becoming shorter, and come the vernal equinox the South Pole will enter into its yearly hibernation—six months of dusk and night. Researchers from Columbia University…

    A Controversy: Fracturing in the Marcellus Shale

    The organic-rich source rock of the Marcellus Shale is an on-going target for massive gas extraction. Advances in horizontal drilling and hydraulic fracturing, or hydrofracking, have made this extensive area of Marcellus black shale one of the largest unconventional and widely controversial gas operations in the United States today.

  • A New Spring Course: Bangladesh: Life on a Tectonically Active Delta

    During the Spring 2012 semester, the Undergraduate Program in Sustainable Development is offering a new and unique senior Capstone Workshop that explores the world’s largest delta in Bangladesh as an example of development challenges in the 21st century.

    Bottom Up or Top Down? Another Way to Look at an Air Quality Problem

    While not all countries have the financial wherewithal and capacity to deploy ground-based instruments for air-quality monitoring, and for some countries monitoring information is not available to the public, for example, through health advisories, another way exists to assess air pollution levels: through satellites.
