Modeling Sea - Level Rise Effects on Population using Global Elevation and Land - Cover Data E. Lynn Usery (2007) http://cegis.usgs.gov/pdf/aag-2007.pdf

Note that this sampling noise in the tide gauge data most likely comes from the water sloshing around in the ocean under the influence of winds etc., which looks like sea - level change if you only have a very limited number of measurement points, although this process can not actually change the true global - mean sea level.

Mike's work, like that of previous award winners, is diverse, and includes pioneering and highly cited work in time series analysis (an elegant use of Thomson's multitaper spectral analysis approach to detect spatiotemporal oscillations in the climate record and methods for smoothing temporal data), decadal climate variability (the term «Atlantic Multidecadal Oscillation» or «AMO» was coined by Mike in an interview with Science's Richard Kerr about a paper he had published with Tom Delworth of GFDL showing evidence in both climate model simulations and observational data for a 50 - 70 year oscillation in the climate system; significantly Mike also published work with Kerry Emanuel in 2006 showing that the AMO concept has been overstated as regards its role in 20th century tropical Atlantic SST changes, a finding recently reaffirmed by a study published in Nature), in showing how changes in radiative forcing from volcanoes can affect ENSO, in examining the role of solar variations in explaining the pattern of the Medieval Climate Anomaly and Little Ice Age, the relationship between the climate changes of past centuries and phenomena such as Atlantic tropical cyclones and global sea level, and even a bit of work in atmospheric chemistry (an analysis of beryllium - 7 measurements).

Satellite observations available since the early 1990s provide more accurate sea level data with nearly global coverage.

Projections for global sea level rise by 2100 range from 8 inches to 6.6 feet above 1992 levels, though the lowest end of this range is a simple extension of historic sea level rise — and recent data indicate this rate has nearly doubled in recent years.

Recently, the 2010 global temperature and satellite sea level data have become available.

These climate - related land storage effects could be significant for global sea - levels, though unfortunately there seem to be very few direct experimental measurements of the factors involved, and so the only studies of these effects seem to have been from computer modelling of data from weather data «reanalysis» models (e.g., ERA - 40).

The main frequency in the sea level data from the University of Colorado is also visible in satellite thermometers like UAH global data, but it seems that the sea level data are not as smeared as the land data may.

But, it seems in a race to find evidence of the global sea level rises predicted by man - made global warming models, a number of researchers have underestimated how problematic the data is.

Individual model parameterizations were constrained by paleontological data, and the overall modeled relationship between global temperature and sea level matched well against records from four previous warm periods: preindustrial, the last interglacial, marine isotope stage 11, and the mid-Pliocene.

Through modeling and with support from paleontological data, Levermann et al. (10) found a roughly linear global mean sea - level increase of 2.3 m per 1 °C warming within a time - envelope of the next 2,000 y.

Whatever the true linear increasing rate of the present global sea level rise is, a look on the data after subtracting a linear function of +3.2 mm per year from the Colorado sea level data shows a remarkable oscillation of about ~ 6.15 periods per year, because this is twice the synodic frequency of Mercury, Earth and Jupiter, with the frequencies of Mercury (4.15204 y ^ -1), Earth (0.9998 y ^ -1) and Jupiter (0.084317 y ^ -1): F = 2 * (4.15204 — 0.99998 — 0.

Despite the various problems with the tidal gauge data, it is possible that the various estimates of global sea level trends of 1 - 2 or maybe 2 - 3 mm / year might coincidentally be correct.
