Geocentric Sea-level Trend Estimates from GPS Analyses at Relevant Tide Gauges World-wide

Technical Rating: star star
Woppelmann et al analyzed data from 160 GPS stations that were within 15 km of tide gauges to determine the vertical movement of the tide gauges. They determined that the global average sea-level rise from January 1999 to August 2005, after correcting the tide gauge data by the vertical land movement, was 1.31 mm/year.

Is Sea Level Rise Accelerating?

Technical Rating: star
The authors of this review paper summarize what is known about past and current rates of sea level rise. They report that "the geocentric rate of global mean sea level rise over the last decade (1993-2003) is +2.8 +/- 0.4 mm/yr, as determined from altimeter measurements," and that "this rate is significantly larger than the historical rate of sea level change measured by tide gauges during the past decades (in the range of 1-2 mm/yr)."

Two Hundred Years of Global Sea Level Data

Technical Rating: star
This study of sea level data determines the long-term trends for 12 large ocean regions, which are combined to produce the mean global sea level. It shows that global sea level rise is irregular and varies greatly over time, and it is not possible to detect a significant increase in the rate of sea level rise over the period 1950-2000.

Twentieth-Century Global Sea Level Rise

Technical Rating: star
High quality long tide gauge records from around the world were analysed to determine a mean global sea level history from 1904 to 2003. The mean rate of global sea level rise was found to be "larger in the early part of the last century (2.03 +/- 0.35 mm/yr 1904-1953), in comparison with the latter part (1.45 +/- 0.34 mm/yr 1954-2003).
