Predictability of twentieth century sea-level rise from past data
The prediction of global sea-level rise is one of the major challenges of climate science. While process-based models are still being improved to capture the complexity of the processes involved, semi-empirical models, exploiting the observed connection between global-mean sea level and global temperature and calibrated with data, have been developed as a complementary approach. Here we investi...
متن کاملTwentieth century sea level: an enigma.
Changes in sea level (relative to the moving crust) are associated with changes in ocean volume (mostly thermal expansion) and in ocean mass (melting and continental storage): zeta(t) = zeta(steric)(t) + zeta(eustatic)(t). Recent compilations of global ocean temperatures by Levitus and coworkers are in accord with coupled ocean/atmosphere modeling of greenhouse warming; they yield an increase i...
متن کاملSea-level Rise Forecast Model
The paper analyzes the melting pace of ice cap in the North Pole and its influence on the rising sea level. The paper constructs the linear and non-linear models between rising sea level and the year by quoting data from Florida Tide Gage Station. The paper also contrasts the two models and selects the non-linear model. By adopting the model, the paper predicts the height of rising sea level ev...
متن کاملOn the rate and causes of twentieth century sea-level rise.
Both the rate and causes of twentieth century global sea-level rise (GSLR) have been controversial. Estimates from tide-gauges range from less than one, to more than two millimetre yr(-1). In contrast, values based on the processes mostly responsible for GSLR-mass increase (from mountain glaciers and the great high latitude ice masses) and volume increase (expansion due to ocean warming)-fall b...
متن کاملContemporary sea level rise.
Measuring sea level change and understanding its causes has considerably improved in the recent years, essentially because new in situ and remote sensing observations have become available. Here we report on most recent results on contemporary sea level rise. We first present sea level observations from tide gauges over the twentieth century and from satellite altimetry since the early 1990s. W...
