High CO2 boosts plant respiration, potentially affecting climate and crops

The leaves of soybeans grown at the elevated carbon dioxide (CO₂) levels predicted for the year 2050 respire more than those grown under current atmospheric conditions, researchers report, a finding that will help fine-tune climate models and could point to increased crop yields as CO₂ levels rise.
