  • New York City’s Bag Fee and the Circular Economy

    While the reduction and eventual elimination of fossil fuel use is a key element of such an economy, so too are the public policies and public-private partnerships needed to collect and reuse discarded products and packages. Bag bills and bottle bills can help develop these capacities. In most of the United States, these ideas have…

    The 2 Million Year Melee: Neanderthals vs. Humans

    Given their adaptation to cold climes and their advanced, albeit under-appreciated, skills, how were Neanderthals beaten out by their human counterparts? The answer lies in a combination of culture and genetics that enabled the successful radiation of humans.

    Meet Pepperoni the Robin, and Friends

    Natalie Boelman and colleagues are tagging American robins near Slave Lake, Alberta, Canada, as the birds migrate north to nesting grounds. In a recent blog post for NASA, she put up videos about their work. You can watch some of them below, or go to the blog page at NASA’s Earth Observatory to see and…

  • Migration Mysteries of the American Robin

    Migration Mysteries of the American Robin

    Ecologist Natalie Boelman is headed back to the far north to study birds—this time to the town of Slave Lake, in northern Alberta, Canada, to track the migration of American robins. She will have some schoolchildren in New York remotely helping her as she and her colleagues get to work.

  • The Presidency and Sustainability

    The president’s accomplishments are particularly noteworthy given the toxic political environment he must operate within. Flint, Michigan’s water crisis provides an example of how partisan politics is dominating federal environmental policy.

  • Navigating Governments’ Obligations in the Context of Land Investments

    Navigating Governments’ Obligations in the Context of Land Investments

    How should governments address the concerns of their citizens tied to land investments? And do their legal obligations constrain their options for doing so? These are increasingly complicated, and pressing, questions.

    How Will Shifting Climate Change U.S. Forests?

    One foggy spring morning just after a hard rain, Park Williams was tromping through the woods deep in Arkansas’ Ozark Mountains. Toiling down a steep slope, he supposedly was keeping a simultaneous eye out for rattlesnakes, copperheads, poison ivy and big old trees. Williams seemed mostly focused on the trees, though; attention to the other…

    In a Vast Ocean, Studying Impact of the Tiniest Creatures

    Vast portions of the oceans contain low levels of the nutrients that normally sustain life. Yet these areas are not devoid of life. Once thought to be biological deserts, recent research has shown that such nutrient-poor marine systems could significantly contribute to the amount of carbon dioxide that is trapped into the deep ocean, influencing…

  • Protecting Our Drinking Water

    The reason we have federal water quality standards is to ensure that local economic issues, politics, racism or other factors do not control decisions about water supply. But in Flint, decisions on water supply were not subject to effective federal review.
