We present new sea-level reconstructions for the past 2100 y based on salt-marsh sedimentary sequences from the US Atlantic coast. The data from North Carolina reveal four phases of persistent sea-level change after correction for glacial isostatic adjustment. Sea level was stable from at least BC 100 until AD 950. Sea level then increased for 400 y at a rate of 0.6 mm/y, followed by a further period of stable, or slightly falling, sea level that persisted until the late 19th century. Since then, sea level has risen at an average rate of 2.1 mm/y, representing the steepest century-scale increase of the past two millennia. This rate was initiated between AD 1865 and 1892. Using an extended semiempirical modeling approach, we show that these sea-level changes are consistent with global temperature for at least the past millennium.
我们根据美国大西洋沿岸的盐沼沉积序列，提供了过去 2100 年的新海平面重建。北卡罗来纳州的数据显示，在进行冰川均衡调整校正后，海平面发生了四个持续变化的阶段。海平面从公元前 100 年到公元 950 年至少保持稳定。海平面随后以每年 0.6 毫米的速度上升了 400 年，随后是一段稳定或略有下降的时期，一直持续到 19 世纪末。从那时起，海平面以平均每年 2.1 毫米的速度上升，这是过去两千年中最陡峭的百年尺度上升。这一速度始于公元 1865 年至 1892 年之间。通过扩展半经验模型方法，我们表明这些海平面变化与过去至少一千年的全球温度一致。
