    Panel on New York’s Future After Sandy

    In a live webcast this afternoon from Hunter College, Earth Institute scientists Cynthia Rosenzweig and Klaus Jacob will join a panel on “Hurricane Sandy and Challenges to the NY Metropolitan Region.”

  • Forecasting Climate’s Effects on Global Food Production

    Forecasting Climate’s Effects on Global Food Production

    The worst drought to hit the U.S. in decades has already brought corn yields to a 17-year low and will almost certainly raise food prices. Wealth will soften the blow in the U.S., but in sub-Saharan Africa and South Asia, prolonged drought has often had deadly consequences. Is there a better way to anticipate climate’s…

  • Fossil Teeth, Traces of Climate & Evolution

    Fossil Teeth, Traces of Climate & Evolution

    From fossil teeth to carbon traces of plants in the soil, scientists are studying how changes in climate may have influenced early human evolution in Africa. Researchers from around the world gathered for a symposium held recently at the Lamont-Doherty Earth Observatory. Watch the videos.

    Did Climate Change Shape Human Evolution?

    “The use of stone to make stone that can cut flesh is important,” Richard Leakey said. “We’re not empirical things, we’re thinkers. … What was it that triggered that response?”

    From Sendai to Rio: A Call for Action

    The people living on the northeast coast of Japan had learned to expect large earthquakes. But despite being one of the best-prepared nations, they were caught off-guard by the force of the March 11, 2011, earthquake and tsunami that devastated their coastline and led to the meltdown of reactors at the Fukushima nuclear power plant.

    New York Roofs: Brighter, Whiter, Cooler

    The results are in for the first study to systematically measure the effects of the city’s fledgling effort to introduce more reflective rooftops in order to reduce cooling costs and the overall heat burden on the city.

  • One Planet, Too Many People?

    One Planet, Too Many People?

    Can we manage the needs of 9 billion people for water, food and energy without depleting our resources and ruining the environment? “The solutions,” says Tim Fox, “are all within the capability of existing technology.”

  • Ecological Succession: Forest Fires to the Ocean Floor

    Ecological Succession: Forest Fires to the Ocean Floor

    A new study reveals that new microbes supplant the active hydrothermal vent’s microbes after the site ceases to produce thermal energy. Though more research is necessary to fully understand the regeneration process in the dormant hydrothermal vents, the study provides an additional platform for ecologists to explore how ecosystems recover from natural unbalances and how…

    Building NYC’s Resilience to Climate Change With Green Infrastructure

    Climate change will impact New York City through more frequent heavy precipitation, sea level rise and rising temperatures. To strengthen its resilience, the city is planting trees and mini-parks, restoring wetlands and installing more permeable surfaces.
