Sea-Level Rise and Coastal Ecosystems

摘要: Coastal ecosystems provide important service functions both for the environment, society and economy. These systems are adapted to various compartments typical wide coastal zone ranging from hinterland shelf margin. Small changes in sea-level can lead significant these posing extreme challenges adding stress resulting human actions possible weather patterns. Climate effects could cause rapid of exceeding capacity adapt. The magnitude IPCC predicted twenty first century global surface temperature exceeds century-scale typically experienced during last several hundred thousands years. However, any predictions climate impacts, including local rise, highly uncertain. While many change assessments conclude that will only rise on order 0.5 m by end century, there is no scientific basis exclude a plausible 2 ±3 m. If such take place, spatial relocation would likely exceed migration speed most ecosystems, loss vital already taking place due anthropogenic dramatically increase. Engineered protection development further limit options ecosystem adaptation through acerbate ecosystems. A strategy hard “hold-the-line” principle softer managed realignment approach giving room may be viable avenue preserving crucial if also option efficient disaster reduction. An assessment risks prudent even we cannot skillfully predict coming decades.
