The Spruce and Peatland Responses Under Climatic and Environmental Change (SPRUCE) project is a partnership between the U. S. Forest Service and the Energy Department.
The SPRUCE research scientists said that they plan to manipulate micro-climates within the research chambers in a way that mimics daily and seasonal temperature variations in the world outside. They will also add and subtract greenhouse gases to determine what impact they have on the living systems. More importantly, they can determine at what level and combinations the changes influence plant and animal life.
"We're trying to find what the balance is and what the tipping points are from microbial processes to large trees."
