  • A delicate balance: Student films examine needs of humans and wildlife in Kenya

    In the summer of 2019, a group of Princeton undergraduates embarked on a six-week Global Seminar in central Kenya, studying ecology and conservation as well as filmmaking fundamentals with Princeton faculty and other renowned instructors.

    Their classroom was Mpala, 48,000 acres of privately owned conservation lands managed by the University in partnership with the Smithsonian Institution, the National Museums of Kenya and the Kenya Wildlife Service.

  • Study helps pinpoint what makes species vulnerable to environmental change

    The fabled use of canaries in coal mines as an early warning of carbon monoxide stemmed from the birds’ extreme sensitivity to toxic conditions compared to humans.

    In that vein, some avian species can indicate environmental distress brought on by overdevelopment, habitat loss and rising global temperatures before an ecosystem has collapsed. Not all bird species, however, respond to environmental disturbances equally.

  • Microbe chews through PFAS and other tough contaminants

    In a series of lab tests, a relatively common soil bacterium has demonstrated its ability to break down the difficult-to-remove class of pollutants called PFAS, researchers at Princeton University said.

    The bacterium, Acidimicrobium bacterium A6, removed 60% of PFAS — specifically perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) — in lab vials over 100 days of observation, the researchers reported in an article in the journal Environmental Science and Technology.

  • Controlling methane is a fast and critical way to slow global warming, say Princeton experts

    In independent studies, two Princeton University research teams recently identified surprisingly large sources of methane, a powerful greenhouse gas, being leaked into the atmosphere. Pound for pound, methane causes a far greater warming effect in the atmosphere than does carbon dioxide — 86-fold more heating over 20 years, and 35-fold more over the course of a century.

  • Princeton collaborators bring layered approach to coastal resiliency in New York City

    As a microcosm of the challenges facing coastal cities around the world, New York’s Jamaica Bay pretty much has it all.

    Home to about 3 million people, one of the world's busiest airports and sensitive coastal ecosystems, Jamaica Bay is a lagoon bordered by Brooklyn and Queens at the southwestern edge of Long Island. This region is vulnerable to an evolving set of threats, including sea-level rise, increasingly intense storms and shifting rainfall patterns.

  • New ‘All for Earth’ podcast addresses environmental issues, solutions

    Thursday, Sep 12, 2019
    by Morgan Kelly, Princeton Environmental Institute

    The new Princeton University podcast “All for Earth” delves into the urgency of today’s environmental crises — as well as the effectiveness of the tools we already have to mitigate them — through in-depth interviews with the people leading the race against time to prevent the implosion of the interconnected systems that support life on Earth.

  • Solutions to urban heat differ between tropical and drier climes

    Wednesday, Sep 4, 2019
    by Molly Sharlach, Office of Engineering Communications

    In summer heat, cities may swelter more than nearby suburbs and rural areas. And while the size of this urban heat island effect varies widely among the world’s cities, heat island intensity can largely be explained by a city’s population and precipitation level, researchers reported in a paper published Sept. 4 in the journal Nature.
