If you plan on attending the AGU Fall Meeting and study hydrology, biogeochemistry, or ecosystem science, please consider submitting an abstract to GC038. Hot Droughts and Hotter Extremes: Investigating Changes in Extreme Events in Hydrology, Aquatic Biogeochemistry, and Ecosystems. This interdisciplinary session aims to investigate the impact of climate extremes on hydrology, biogeochemistry, and ecosystems with a particular focus on the pending ‘hot drought’ phenomenon.  What types of changes can we expect in the environment during future droughts compounded with the expected increases in temperature through the 21st century? This will be explored and discussed through the lens of these three disciplines by examining changes that are occurring within the atmosphere or terrestrial environment for any ecosystem.


Session Conveners: Kurt Solander1, Martha A Scholl2, Hyungjun Kim3 and Chonggang Xu1, (1) Los Alamos National Laboratory, Los Alamos, NM, United States (2) USGS Headquarters, Reston, VA, United States (3) The University of Tokyo, Institute of Industrial Science, Tokyo, Japan
