The red line
shows tide gauge data (Church & White 2006).
I showed tide gauge data before, and here is another one.

Raw
data collected from altimeters have been re-processed and collated with wind speed
data from scatterometers and sea level measurements from
tide gauges, to
show the spatial structure of each storm.
Satellite
data shows a linear trend of 3.3 ± 0.4 mm / year and the
tide gauge reconstruction trend is slightly less.
Stefan, In your paper, you
show that the
tide gauge data falls at the low end of the uncertainty in the satellite altimeter.
Shown is the past history of sea level since the year 1700 from proxy
data (sediments, purple) and multiple records from
tide gauge measurements.
If one wants to discuss changes in rate within the past twenty years one should really only use the satellite
data for that and not the rate curves from the
tide gauges shown here.

Looking at global
data (rather than
tide gauge records just from the U.S.)
show that sea level rise has been increasing since 1880.
This is a global
data set, and it's a worldwide average so its
shows vastly less noise than individual
tide gauge records.
Tide -
gauge data from Diego Garcia (1988 — 2000, and 2003 — 2011)
show no statistically significant long - term rise, whilst the rates of rise obtained from the satellite altimeter record for 1993 — 2011 span the range of 0.16 — 4.56 mm yr − 1 in the surrounding sea areas (70 — 74 ° E and 4 — 9 ° S) and are also consistent with a zero rate except in the far south of the region... this has been a relatively stable physical environment, and that these low - lying coral islands should continue to be able to support human habitation, as they have done for much of the last 200 years.
Estimates from proxy
data1 (for example, based on sediment records) are
shown in red (1800 - 1890, pink band
shows uncertainty),
tide gauge data in blue for 1880 - 2009,2 and satellite observations are
shown in green from 1993 to 2012.3 The future scenarios range from 0.66 feet to 6.6 feet in 2100.4 These scenarios are not based on climate model simulations, but rather reflect the range of possible scenarios based on other kinds of scientific studies.
The long - term
tide gauges in the Mediterranean
show sea - level trends for the 20th century in the range of 1.1 — 1.3 mm / yr whilst more recent satellite altimetry
data reveals much larger increases in sea - level throughout the basin towards the latter part of the century.
However, the
tide -
gauge literature
data shows the current, rather slow but steady as opposed to accelerating, rate started in 1850, long before CO2 warming could have been the cause.
Finally NOAA 2016 updated coastal sea level rise
tide gauge data shows no acceleration in sea level rise along the California coastline or anywhere else despite false claims by the UN IPCC that man made emissions have been increasing rates of sea level rise since the 1970's.
Gavin Schmidt investigated the claim that
tide gauges on islands in the Pacific Ocean
show no sea level rise and found that the
data show a rising sea level trend at every single station.
Bill Innis: Jevrejeva's most recent
tide gauge data from 2003 to 2009
shows sea level is actually falling The
data will likely become available soon.
The
data - adjusters take misaligned and incomplete sea level
data from
tide gauges that
show no sea level rise (or even a falling trend).
Abstract: Mean - sea - level
data from coastal
tide gauges in the north Indian Ocean wereare used to
show that low - frequency variability is consistent among the stations in the basin.
As we have
shown in Rahmstorf et al. (2012), much or most of the decadal variations in the rate of sea - level rise in
tide gauge data are probably not real changes at all, but simply an artefact of inadequate spatial sampling of the
tide gauges.
For the past, proxy
data are
shown in light purple and
tide gauge data in blue.
All
data from
tide gauges in areas where land is not rising or sinking
show instead a steady linear and unchanging sea level rate of rise from 4 up to 6 inches / century, with variations due to gravitational factors.
The Telegraph did at least contrast the sea level fall at the
tide gauge with remote sensing
data showing general sea level rise, although it neglected to mention that the remote sensing studies relate to a broader spatial scale than the
tide gauges.
