For example, [Kruss 1983] has this to say about the Lewis glacier on Mt. Kenya: «A decrease in the annual precipitation on the order of 150 mm in the last quarter of the 19th century, followed by a secular air temperature rise of a few tenths of a degree centigrade during the first half of the 20th century, together with associated albedo and cloudiness variation, constitute the most likely cause of the Lewis Glacier wastage during the last 100 years.»

The overall pattern remains, though: about 1 mm / year in the beginning of the century, around 1.5 — 2 mm / year in the middle of the century, rising to 3 mm / yr at the end of the century.

Can anyone please explain to me what I'm missing because looking at satellite data from university of Colorado (http://sealevel.colorado.edu/) its obvious that the annual sea level rise is contained at 3.3 mm / year.

But again the «models» estimate includes an observed ice sheet mass loss term of 0.41 mm / year whereas ice sheet models give a mass gain of 0.1 mm / year for this period; considering this, observed rise is again 50 % faster than the best model estimate for this period.

If the melting rate continues to stay within those two points, and given that the current contribution to sea level from the Greenland Ice Sheet is only about 0.1 mm / year, we won't see a lot of sea level rise until later this century.
