    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.

    #100. Taking a Fresh Look at Five Issues

    This is the 100th blog I’ve written for the State of the Planet. It seemed like a good occasion to take a look at my five most popular blogs to see what has changed in the years since they were written. Is the news better or worse for seawater greenhouses, plastic pollution, turning wastewater into…

  • Microbeads, Marine Debris, Regulation and the Precautionary Principle

    It is clear that the hunger for economic growth and wealth pushes business and governments to ignore environmental impacts that are considered an inevitable byproduct of development. But this fails to account for the costs that will inevitably be borne when the damage must be cleaned up.

  • Genetic Analysis of Asian Elephants in India Reveals Some Surprises

    Researchers find one population actually two; suggest strategies for future elephant conservation

  • What Is Ocean Acidification & Why Does It Matter?

    What Is Ocean Acidification & Why Does It Matter?

    Excess carbon dioxide absorbed into the oceans is starting to have profound effects on marine life, from oysters to tiny snails at the base of the food chain. Our scientists explain the changes and what they are learning about ocean acidification in the past.

    World Wildlife Fund, Earth Institute Form New Partnership

    The World Wildlife Fund will collaborate with the Earth Institute’s Center for Climate Systems Research to advance adaptation to the impacts of climate change around the globe. The partners will create new ways of generating climate risk information and embedding it into the World Wildlife Fund’s conservation and development planning, policies and practice.

    The Catskill Watershed: a Story of Sacrifice and Cooperation

    It has become so easy for us here in NYC to turn on the tap without realizing the hardship, unimaginable sacrifices and money that have allowed us this incredible resource at the mere flick of a finger. We returned to the downstream end of the aqueducts with a newfound appreciation of the hard work we…

  • Climate Is Changing Fast in West Antarctica

    Climate Is Changing Fast in West Antarctica

    Fast-rising temperatures on the Antarctic Peninsula are having an impact on the ice and marine life, and providing clues about future ecosystem changes elsewhere.
