--- res: bibo_abstract: - Atmospheric carbon dioxide concentration ([CO 2 ]) is increasing, which increases leaf-scalephotosynthesis and intrinsic water-use efficiency. These direct responses have the potential toincrease plant growth, vegetation biomass, and soil organic matter; transferring carbon from theatmosphere into terrestrial ecosystems (a carbon sink). A substantial global terrestrial carbon sinkwould slow the rate of [CO 2] increase and thus climate change. However, ecosystem CO2responses are complex or confounded by concurrent changes in multiple agents of global changeand evidence for a [CO 2]-driven terrestrial carbon sink can appear contradictory. Here wesynthesize theory and broad, multidisciplinary evidence for the effects of increasing [CO 2](iCO 2) on the global terrestrial carbon sink. Evidence suggests a substantial increase in globalphotosynthesis since pre-industrial times. Established theory, supported by experiments,indicates that iCO 2 is likely responsible for about half of the increase. Global carbon budgeting,atmospheric data, and forest inventories indicate a historical carbon sink, and these apparentiCO 2 responses are high in comparison to experiments and predictions from theory. Plantmortality and soil carbon iCO 2 responses are highly uncertain. In conclusion, a range of evidencesupports a positive terrestrial carbon sink in response to iCO2 , albeit with uncertain magnitudeand strong suggestion of a role for additional agents of global change.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Anthony P. foaf_name: Walker, Anthony P. foaf_surname: Walker - foaf_Person: foaf_givenName: Martin G. foaf_name: De Kauwe, Martin G. foaf_surname: De Kauwe - foaf_Person: foaf_givenName: Ana foaf_name: Bastos, Ana foaf_surname: Bastos - foaf_Person: foaf_givenName: Soumaya foaf_name: Belmecheri, Soumaya foaf_surname: Belmecheri - foaf_Person: foaf_givenName: Katerina foaf_name: Georgiou, Katerina foaf_surname: Georgiou - foaf_Person: foaf_givenName: Ralph F. foaf_name: Keeling, Ralph F. foaf_surname: Keeling - foaf_Person: foaf_givenName: Sean M. foaf_name: McMahon, Sean M. foaf_surname: McMahon - foaf_Person: foaf_givenName: Belinda E. foaf_name: Medlyn, Belinda E. foaf_surname: Medlyn - foaf_Person: foaf_givenName: David J.
