The Amazon Rainforest is a living warehouse for carbon dioxide. As climate changes, the lush tropical ecosystems of the Amazon Basin may release more carbon dioxide into the atmosphere than they absorb. NOAA scientist John Miller talks about how climate conditions in 2010 and 2011 created a natural experiment on how drought affects the Amazon's carbon balance.

This short video, is the fifth in the National Academies Climate Change, Lines of Evidence series. It focuses on greenhouse gases, climate forcing (natural and human-caused), and global energy balance.
