Atmospheric CO2 and Terrestrial Carbon Feedback CO2 effects on terrestrial ecosystem carbon subsidize CO2 emissions and are complex, uncertain, and likely to decline into the future. Atmospheric CO2 is increasing, leading to climate change. Increasing CO2 also increases leaf-scale photosynthesis and water-use efficiency, which has the potential to increase plant biomass and soil organic matter. … Continue reading Atmospheric CO2 and Terrestrial Carbon Feedback
