Grasslands under extreme climate events

Researchers report that grasslands exposed to conditions predicted for the 2050s, including extreme heat waves, drought, and elevated atmospheric CO2 concentrations, may continue to serve as carbon sinks, likely by increasing nitrogen uptake and root growth after periods of heat and drought, findings that suggest that future elevated CO2 concentrations may help plants compensate for periods marked by a lack of growth during extreme climate events. - Read at PNAS.org
