Sea level has been rising for 20,000 years, since the end of the last ice period. Some sea level rise is normal. Is the rate of sea level rising because of man? What does the observation show?

NOAA 375 global tidal gauges also demonstrate quite clearly that there has been no increase in the rate of sea level rise in the past one to two centuries link Please note that some stations show a reduction in sea level, this is due to the land rising. This also highlights the difficulty in accurately measuring the rate of sea level rise.

East Coast USA sea level rise uneven, area with largest rise, MD, VA, NC have the largest post ice age affect. We were surprised that the largest rates of sea level change due to the last ice age are found in Maryland, Virginia, and North Carolina, explaining 75 percent of the observed variation along the East Coast, Across the past century, records indicated that sea level rise has varied – from approximately 1.5 feet along the shores of the Chesapeake Bay in Virginia and the beaches near Cape Hatteras, North Carolina, to approximately one foot near New York City and Miami. Along the coast of Maine, sea level rose only about a half a foot.. link

Satellite data different tidal gauges, impact of increasig tropopspheric water vapor link NOAA states that global sea level rise shown by tide gauges is 1.7mm/year, or 6.7 inches per century. NASA satellite records since 1994 indicates the rate is now 3.2mm/year, still only 12.6 inches per century but almost double the tide gauge records.

"We expected that the coast would start to retreat due to sea level rise, but the most surprising thing is that the coasts are growing all over the world," said Dr Baart.

Coastal areas were also analysed, and to the scientists surprise, coastlines had gained more land - 33,700 sq km (13,000 sq miles) - than they had been lost to water (20,100 sq km or 7,800 sq miles).

Judith Curry "“At best, the determination and attribution of global-mean sea-level change lies at the very edge of knowledge and technology. Both systematic and random errors are of concern, the former particularly, because of the changes in technology and sampling methods over the many decades, the latter from the very great spatial and temporal variability. It remains possible that the database is insufficient to compute mean sea-level trends with the accuracy necessary to discuss the impact of global warming, as disappointing as this conclusion may be.”

• Sea level was apparently higher than present at the time of the Holocene Climate Optimum (~ 5000 years ago), at least in some regions.
• Tide gauges show that sea levels began to rise during the 19th century, after several centuries associated with cooling and sea level decline. Tide gauges also show that rates of global mean sea level rise between 1920 and 1950 were comparable to recent rates.
• Recent research has concluded that there is no consistent or compelling evidence that recent rates of sea level rise are abnormal in the context of the historical records back to the 19^th century that are available across Europe.
