    American Geophysical Union 2017: Key Events From the Earth Institute

    A chronological guide to key talks and other events presented by Columbia University’s Earth Institute at the American Geophysical Union 2017 meeting.

    Study: Overuse of Water Threatens Global Food Supply

    In recent years, scientists have revealed that we are depleting our global groundwater reserves at an alarming rate. Now researchers have shown that a significant share of this unsustainable water use fuels the global food trade, which means water exhaustion in supplier nations could ripple outward, causing food crises half way across globe.

    How We Know Today’s Climate Change Is Not Natural

    Despite the many climate “skeptics” in key positions of power today, 97 percent of climate scientists agree that the warming of Earth’s climate over the last 100 years is mainly due to human activity. Why are they so sure?

    Trump’s Unifying Opportunity: Food Security

    A sound strategy to secure the nation’s food supply and reduce its vulnerability within and beyond our borders will be a major step towards making America and the world more resilient in the face of increasing uncertainty.

    2016 Sets Another Record for Warmth

    The news doesn’t come as a surprise to scientists and others who’ve been watching, but marks a milestone nonetheless: 2016 was the warmest year on record, dating back to the start of modern record keeping in 1880.

    Mapping Risks and Building Resilience, from Plot to Plate

    Michael Puma, an associate research scientist at the NASA Goddard Institute for Space Studies and a Center for Climate and Life Fellow, works to improve understanding of the fragility of the global food system and how it might respond to major disruptions.

    Extreme-Weather Winters Becoming More Common in U.S., Study Shows

    This past July was Earth’s hottest month since record keeping began, but warming isn’t the only danger climate change holds in store. Recent years have seen a dramatic increase in the simultaneous occurrence of extremely cold winter days in the Eastern United States and extremely warm winter days in the Western U.S., according to a…

    Study Downgrades Groundwater Contribution to Sea Level Rise

    Some research suggests that, along with melting ice sheets and glaciers, the water pumped from underground for irrigation and other uses, on the rise worldwide, could contribute substantially to rising sea levels over the next 50 years. A new study published in Nature Climate Change says the magnitude is substantially lower.

    Internships: Work with NASA Scientists on Climate Change

    An internship program at the NASA Goddard Institute for Space Studies in New York is offering graduate students a chance to work with NASA scientists on climate change research.
