The 90 % confidence range for the linear twentieth century rise predicted by the semi-empirical model is 13 — 30 cm, whereas the observed interval (using two
tide gauge data sets) is 14 — 26 cm.

data from
tide gauges and satellite altimeters, which measure sea surface heights.
In Aden, similar to Karachi and Mumbai and other
tide gauges of the area, a single -

This is a global
data set, and it's a worldwide average so its shows vastly less noise than individual
tide gauge records.

And now — based on sea level behavior between 1930 and 2010, as derived from United States
tide gauge data, plus extensions of previous global -
gauge analyses — a new empirical study, which does not rely on a relationship between sea level and temperature, casts doubt upon both
sets of projections.
