Global Change Research
headline bar

Our mission is to determine and interpret agroecosystem responses to atmospheric and soil processes induced by global change.

Our overall goals are to:

  • Reduce uncertainty regarding the effects of rising atmospheric CO2 concentration on crops, pastures, invasive weeds, and plant diseases.

  • Determine the role of agronomic management practices in the production of CO2 and other greenhouse gases, as well as the sequestration of atmospheric CO2 as organic C in soils.

This program addresses the carbon issue at several scales, from controlled laboratory environments to outdoor field exposures to elevated CO2.

The earth's atmospheric CO2 concentration has
increased 30% in two centuries. The effects
of this increase remain largely unknown.
