Face Science

FACE Program | Homepage

The goal of FACE science is to study the effects of elevated [CO2] (and in some cases other factors associated with global change) on plants and ecosystems under as close to real world conditions as possible. The principal aims are:

  • To advance the understanding of the processes that regulate the carbon balance of ecosystems, including feedbacks between carbon, nutrient, and water cycles.
  • To understand the impact of elevated [CO2] on ecosystem function and structure.

Individual FACE experiments outline their specific research goals and maintain a list of publications on their web sites.  Below we have listed some of the review or synthesis papers that summarize the current state of FACE Science.
