For the first time, the American Geophysical Union's (AGU) global Earth and space science community will gather in Washington, D.C. for Fall Meeting 2018. The Fall Meeting 2018 will highlight and celebrate the latest scientific discoveries, insights and advances in the many fields of research that AGU encompasses. This year’s location also provides a special opportunity – to stand together to show the world that scientific collaboration is international, interdisciplinary, and indispensable – and to demonstrate the value of our science to policy makers, thought leaders and the public.
