Rising atmospheric CO2 concentration is a well-established phenomenon with potentially major impacts on terrestrial vegetation. Grasslands are important when considering the effects of elevated CO2 because they make up a large and economically-significant part of the earth's plant cover, and substantial long-term changes in the functioning of grassland ecosystems may be expected. This brief overview covers some of the aspects of current research addressing such questions as the probability and possible magnitude of carbon storage by grasslands, differential responses of constituent species to rising atmospheric CO2, changes in turnover rates and other aspects of ecosystem function. Recent methodological developments, and possible directions and needs of future research on plant responses to elevated CO2 are briefly considered.
