我们提出了一个简单的关系,全球海平面变化的时间尺度上的几十年到几个世纪的全球平均温度。这种关系是测试的合成数据,从全球气候模式为过去的千年和下一个世纪。当应用于1880-2000年的海平面和温度观测数据时,并考虑到已知的人为水文对海平面的贡献,相关性>0.99,解释了98%的方差。对于政府间气候变化专门委员会第四次评估报告中的未来全球温度情景,该关系预测1990-2100年期间海平面上升75至190厘米。
We propose a simple relationship linking global sea-level variations on time scales of decades to centuries to global mean temperature. This relationship is tested on synthetic data from a global climate model for the past millennium and the next century. When applied to observed data of sea level and temperature for 1880–2000, and taking into account known anthropogenic hydrologic contributions to sea level, the correlation is >0.99, explaining 98% of the variance. For future global temperature scenarios of the Intergovernmental Panel on Climate Change's Fourth Assessment Report, the relationship projects a sea-level rise ranging from 75 to 190 cm for the period 1990–2100.
