storage ; however, this change in the dominant vegetation and associated faunal changes can modify carbon stocks and sequestration, as well as other ecosystem services . Landward range expansion of mangroves, marshes and seagrass in response to gradual RSLR can enhance carbon sequestration , but coastal squeeze can limit this  and RSLR can either submerge and bury or erode and release stored blue carbon . Gains and losses of mangrove habitat area  projected for nations under RCP4.5 and RCP8.5 depend primarily on the combination of SLR rate, adaptation scenario  and island or continental status . The influence of warming, MHWs and acidification on seagrass meadows , and associated coralligenous reefs , suggests that future warming and especially MHWs will cause more widespread loss of services from these ecosystems . Loss of blue carbon ecosystems will not only halt carbon storage but also release stored carbon: emissions after 2000 due to global mangrove deforestation have been estimated at 23.5-38.7 Tg Cyr-1 . Mitigation estimates for avoided conversion and restoration of coastal wetlands and the implications of the impacts of climate change are assessed in WGIII AR6 Section 7.4.
