  • High CO2 boosts plant respiration, potentially affecting climate and crops

    Andrew Leakey's team made use of the Soybean Free Air Concentration Enrichment (Soy FACE) facility at Illinois. This open-air research lab can expose a soybean field to a variety of atmospheric CO2 levels - without isolating the plants from other environmental influences, such as rainfall, sunlight and insects.
