AsanthropogenicemissionsandwarmingcontinuetoalterEarth’senvironment,itisessential to highlight future impacts that can be avoided through mitigation. Here we use two ensembles of theCommunityEarthSystemModel(CESM)rununderthebusiness-as-usualscenario,RCP8.5,andthemitigation scenario, RCP 4.5, to identify avoidable impacts of anthropogenic warming on marine net primary production (NPP). We emphasize the use of ensembles so as to distinguish long-term, anthropogenictrendsinmarineproductivityfrominternalvariability.TwentiethcenturygloballyintegratedmarineNPPis 55.7±1PgC,withmuchofthevariabilityattributabletocertainregions(e.g.,theequatorial Pacific).CESMprojectionsindicatethatglobalmarineNPPwilldropby ∼4%by2080ifwefollowRCP8.5, Grant no.
