Recent global sea level acceleration started over 200 years ago?

Sea-Level Rise from the Late 19th to the Early 21st Century
John A. Church • Neil J. White
Surv Geophys (2011) 32:585–602
DOI 10.1007/s10712-011-9119-1
“Abstract We estimate the rise in global average sea level from satellite altimeter data for 1993–2009 and from coastal and island sea-level measurements from 1880 to 2009. For
1993–2009 and after correcting for glacial isostatic adjustment, the estimated rate of rise is 3.2 ± 0.4 mm year-1 from the satellite data and 2.8 ± 0.8 mm year-1 from the in situ data. The global average sea-level rise from 1880 to 2009 is about 210 mm. The linear trend from 1900 to 2009 is 1.7 ± 0.2 mm year-1 and since 1961 is 1.9 ± 0.4 mm year-1. There is considerable variability in the rate of rise during the twentieth century but there has been a statistically significant acceleration since 1880 and 1900 of 0.009 ± 0.003 mm year-2 and 0.009 ± 0.004 mm year-2, respectively. Since the start of the altimeter record in 1993, global average sea level rose at a rate near the upper end of the sea level projections of the Intergovernmental Panel on Climate Change’s Third and Fourth Assessment Reports.
However, the reconstruction indicates there was little net change in sea level from 1990 to 1993, most likely as a result of the volcanic eruption of Mount Pinatubo in 1991”.

Global sea level linked to global temperature
Martin Vermeera,1 and Stefan Rahmstorfb
Department of Surveying, Helsinki University of Technology, P.O. Box 1200, FI-02150, Espoo, Finland; and bPotsdam Institute for Climate Impact Research,
Telegrafenberg A62, 14473 Potsdam, Germany
Edited by William C. Clark, Harvard University, Cambridge, MA, and approved October 26, 2009 (received for review July 15, 2009)
“We propose a simple relationship linking global sea-level variations on time scales of decades to centuries to global mean temperature. This relationship is tested on synthetic data from a global climate model for the past millennium and the next century. When applied to observed data of sea level and temperature for 1880–2000, and taking into account known anthropogenic hydrologic contributions to sea level, the correlation is >0.99, explaining 98% of the variance. For future global temperature scenarios of the Intergovernmental Panel on Climate Change’s Fourth Assessment Report, the relationship projects a sea-level rise ranging from 75 to 190 cm for the period 1990–2100.

Contemporary Sea Level Rise
Annual Review of Marine Science
Vol. 2: 145-173 (Volume publication date January 2010)
First published online as a Review in Advance on September 28, 2009
DOI: 10.1146/annurev-marine-120308-081105
“We show that for the 1993–2007 time span, the sum of climate-related contributions (2.85 ± 0.35 mm year?1) is only slightly less than altimetry-based sea level rise (3.3 ± 0.4 mm year?1): 30% of the observed rate of rise is due to ocean thermal expansion and 55% results from land ice melt. “

Rates of sea-level change over the past century in a geocentric reference frame
GEOPHYSICAL RESEARCH LETTERS, VOL. 36, L12607, 6 PP., 2009
“The sea level trends obtained in the ITRF2005 reference frame are more consistent than in the ITRF2000 or corrected for Glacial-Isostatic Adjustment (GIA) model predictions, both on the global and the regional scale, leading to a reconciled global rate of geocentric sea level rise of 1.61 ± 0.19mm/yr over the past century in good agreement with the most recent estimate”

Sorry  Ufox the the  majority  consensus science in peer reviewed  journals again defeats you! I could give many more papers  to prove this contention!
Ufox you dill, measurements over short time frames  like 30 months mean nothing!You need to look at long term trends of at least 25 years or longer! Sadly like the other climate skeptic dills on flounders you do not know the difference between weather and climate!! No hope for you it appears! Back to "poetry"! or metal detector design for beginners! LOL

Spot on!!! Even I know 30 months is nothing, you joke Ufox  rolleye 1

By the way what was that "poetry" that the admin. removed? It must of being pretty bad for it to go, as I've never seen them remove anything to date!! So I think theirs your answer Ufox to "how do you like my poetry"

As usual UF's latest post about the latest GISS/NASA data not conforming with the hockey stick is just plain wrong!!
GLOBAL SURFACE TEMPERATURE CHANGE
J. Hansen,1 R. Ruedy,1 M. Sato,1 and K. Lo1
Received 3 June 2010; revised 10 August 2010; accepted 23 August 2010; published 14 December 2010.

[1] We update the Goddard Institute for Space Studies (GISS) analysis of global surface temperature change,compare alternative analyses, and address questions about perception and reality of global warming. Satellite?observed night lights are used to identify measurement stations located in extreme darkness and adjust temperature trends of urban and periurban stations for nonclimatic factors, verifying that urban effects on analyzed global change are small. Because the GISS analysis combines available sea surface temperature records with meteorological station measurements, we test alternative choices for the ocean data, showing that global temperature change is sensitive to estimated temperature change in polar regions where observations are limited.We use simple 12 month (and n × 12) running means to improve the information content in our temperature graphs. Contrary to a popular misconception, the rate of warming has not declined. Global temperature is rising as fast in the past decade as in the prior 2 decades, despite year to year fluctuations associated with the El Niño/La Niña cycle of tropical ocean temperature. Record high global 12 month running mean temperature for the period with instrumental data was reached in 2010.

Berkeley Earth Temperature Averaging Process

Abstract
A new mathematical framework is presented for producing maps and large-scale averages of temperature changes from weather station data for the purposes of climate analysis.
This allows one to include short and discontinuous temperature records, so that nearly all temperature data can be used. The framework contains a weighting process that assesses the quality and consistency of a spatial network of temperature stations as an integral part of the averaging process. This permits data with varying levels of quality to be used without compromising the accuracy of the resulting reconstructions. Lastly, the process presented here is extensible to spatial networks of arbitrary density (or locally varying density) while maintaining the expected spatial relationships. In this paper, this framework is applied to the Global Historical Climatology Network land temperature dataset to present a new global land temperature reconstruction from 1800 to present with error uncertainties that include many key effects. In so doing, we find that the global land mean temperature has increased by 0.911 ±0.042 C since the 1950s (95% confidence for statistical and spatial uncertainties).
 This change is consistent with global land-surface warming results previously reported, but with reduced uncertainty.

The lesson? Always look at all the data, don't be fooled by selective presentations.

October 29, 2010)
We present new sea-level reconstructions for the past 2100 y based on salt-marsh sedimentary sequences from the US Atlantic coast.The data from North Carolina reveal four phases of persistent sea-level change after correction for glacial isostatic adjustment. Sea level was stable from at least BC 100 until AD 950. Sea level then increased for 400 y at a rate of 0.6 mm/y, followed by a further period of stable, or slightly falling, sea level that persisted until the late 19th century.
 Since then, sea level has risen at an average rate of 2.1 mm/y, representing the steepest century-scale increase of the past two millennia. This rate was initiated between AD 1865 and 1892. Using an extended semiempirical modeling approach, we show that these sea-level changes are consistent with global temperature for at least the past millennium.

These are the classic methods used by Ufox and other climate skeptics
 Lying Or Reckless Disregard For the Truth
• Focusing On Unknowns While Ignoring The Knowns. (a classic tactic used by Ufox and other climate skeptics!)
• Specious Claims Of "Bad" Science (another tactic used by Ufox!!!)
• Creation of Front Groups
• Manufacturing Bogus Climate Science
• Think Tank Campaigns
• Misleading PR Campaigns.
• Creation of Astroturf Groups
• Cyber-bullying Scientists and Journalists


Oh dear Ufox shot down again sad1
Its getting boring "beating" him up so easily! Good science and correlated data sets will beat him every time!
