    At AGU, Earth Institute’s Columbia Water Center Adds to the Abundance of Scientific Riches

    The annual American Geophysical Union (AGU) meeting is an all-you-can-eat buffet of the most current scientific knowledge available on the planet. Name your pleasure: space, climate change, geomagnetism, nonlinear geophysics, volcanology, biogeosciences, etc. You have to be careful to indulge in moderation over the five-day event, or risk unseemly bloating. The Columbia Water Center contributed…
