  • Illuminating the Science: Art and Climate Change Part II

    Last week I expressed some skepticism that art and climate science were complementary languages. I also expressed some hope that the nature of these two fields – that is, that they both are ways of better knowing the world – really were reconcilable, and could create a better robustness of understanding the natural world. I’m glad…

  • Mandating energy benchmarking: the next step for cities in addressing climate change?

      by Marne Sussman Within the past two years, two cities in the U.S. have passed ordinances mandating that existing buildings benchmark their energy usage. Benchmarking requires a building owner to report energy use data which can then be compared to data from buildings of a similar size and function and to past data from…

  • Year Without a Summer? Not this Time.

    You may have heard about the Year Without the Summer, 1816, when severe climate anomalies linked to the eruption of Indonesia’s Mt Tambora provoked widespread famine, the westward expansion of the United States, the invention of the bicycle, and Frankenstein. So epic, so influential: Tales of the dramatic climate impacts of that fateful year got…

  • The Desert Margins – vulnerable to desertification, but not hopeless

    Most people are aware that vegetative cover, such as trees or other shade producing plants, helps to keep moisture in the soil, especially in the driest climates. Not all plants have the same effect, though.

  • Creating More Useful Forecasts

    Seasonal forecasts can be effective tools for agricultural planners, water resources managers and other decision makers. For example, after torrential rains and floods wreaked havoc in the West African nation of Ghana in 2007, displacing some 400,000 people there, the regional office of the International Federation of Red Cross and Red Crescent Societies started using…

  • Taro Takahashi Wins Top U.N. Award for Environmental Leadership

    The United Nations has awarded Taro Takahashi, a geochemist at Lamont-Doherty Earth Observatory, its highest honor for environmental leadership, the Champions of the Earth award, for his research on the oceans’ uptake of carbon dioxide and its implications for global warming. He was presented with a trophy and a $40,000 prize on Thursday, April 22,…

  • Study Reconstructs Asia’s Most Devastating Droughts

    Key to Understanding Monsoon and Climate’s Impacts

  • Illuminating the Science: Art and Climate Change

    On Thursday I’ll be attending Illuminating the Science: Art and Climate Change. The event’s project is surely ambitious.  It claims not only that climate data might be better communicated, or made more robust, through the arts, but that indeed “the landscape of numbers can be populated by dreams in the form of images, dance or music,…

  • Addressing urban water scarcity in developing countries: Chennai, India

    Ensuring an adequate water supply isn’t only an issue for large urban centers like New York or Los Angeles. It’s also a vital concern of the growing populations of cities in the developing world. Veena Srinivasan, of the Department of Environmental Earth System Science, Stanford University, shared her work on ‘The integrated water paradigm: a…

Colorful icons representing nature, sustainable living, and renewable energy with text "Earth Day 2026"

The first Earth Day in 1970 ignited a movement to stop polluting our planet. Today, our scientists and experts are tackling the most pressing challenges to achieve real-world impact. This Earth Day, join us in our commitment to realizing a just and sustainable future for our planet. Visit our Earth Day website for ideas, resources, and inspiration.
