INSTAAR at AGU: Talks, posters, and sessions at the American Geophysical Union (AGU) Fall Meeting

INSTAAR faculty and graduate students will share their research at the American Geophysical Union (AGU) Fall Meeting held in San Francisco, 9 to 13 December. They will present new research on abrupt climate change, atmospheric chemistry, geomorphology, rivers and oceans, forests and snow, plants and soils, past climates, flood monitoring, Antarctic volcanoes, coastal erosion, and emissions from energy production.
