Rising sea levels.

I saw this vid recently that describes the basic issues with measuring sea levels.

By "actually is rising less than at any time over the last ten or so thousand years" are you referring to "no rise at all has happened in the last two years"?
from wiki:
Short-term variability and long-term trends
On the timescale of years and decades, sea level records contain a considerable amount of variability.[29] For example, approximately a 10 mm rise and fall of global mean sea level accompanied the 1997–1998 El Niño-Southern Oscillation (ENSO) event, and a temporary 5 mm fall accompanied the 2010–2011 event.[30] Interannual or longer variability is a major reason why no long-term acceleration of sea level has been identified using 20th century data alone. However, a range of evidence clearly shows that the rate of sea level rise increased between the mid-19th and mid-20th centuries.[31] Sea level acceleration up to the present has been about 0.01 mm/yr² and appears to have started at the end of the 18th century. Sea level rose by 6 cm during the 19th century and 19 cm in the 20th century.[32] Evidence for this includes geological observations, the longest instrumental records and the observed rate of 20th century sea level rise. For example, geological observations indicate that during the last 2,000 years, sea level change was small, with an average rate of only 0.0–0.2 mm per year. This compares to an average rate of 1.7 ± 0.5 mm per year for the 20th century.[33]

No, I was referring to the actual agencies concerned with creating the data that have stated in the last couple of years there is no measurement that shows an increase in sea level at all. from wiki:

But if you want to scaremonger the best route is to use small 30 year snippets to demonstrate a case but ignore the fact that if we transposed the 1925 - 55 data over the last thirty years data we could argue that the rate of sea level rise has abated somewhat.
Modern humans have experienced sea level changes of 120m or more so you would have thought by now we'd have copped on a bit and realised that you can't hold the sea back.
You're not dutch are you Modern humans have experienced sea level changes of 120m or more so you would have thought by now we'd have copped on a bit and realised that you can't hold the sea back.
Oh God here we go.
You obviously didn't read what I said. 'the agencies concerned with creating the data', not those that 'interpret' it to read what you want to hear.

But taking all that to one side, I really don't care enough to enter into ridiculous debate about it as the tide has not reached my ankles yet in my lounge and at even the worst forecasted rate I should have 300 years before it reaches my nostrils, at which point I shall just move in full time on the boat and be fairly secure from any rise however catastrophic.

Read the first two and couldn't find any "actual agencies concerned with creating the data that have stated in the last couple of years there is no measurement that shows an increase in sea level at all"You obviously didn't read what I said.

The dates on the next two don't look relevent so didn't bother.
The last one is more a 'actual agencies concerned with producing data are lying dooshbags' type of thing.

You're not Kerplunk's little brother are you? Or substitute.What are your thoughts on 'Arctic Ice Melt'(C)IPCC 2011?
If indeed 'he', I'm guessing a new dawn of self-realisation on re-entry but a broken 'o' key...
