Christopher Monckton made a similar observation a few years ago, and was wrong in implying the sea levels had stopped rising then. I don't know how much impact La Niña has but so far this "blip" is a smaller diversion from the trend than the "blip" around 2007.

New Sea Level page from University of Colorado: Source: sealevel.colorado.edu/They write: "Welcome to the new webpages from the University of Colorado sea level group! We apologize for the delay in updating our sea level releases, but the transition to these new web pages took longer than we thought. In addition, we have made many improvements to our data (new orbits, new tide model, new corrections) which ultimately had little effect on global mean sea level, but brought us up to date with the latest advances in the field. One important change in these releases is that we are now adding a correction of 0.3 mm/year due to Glacial Isostatic Adjustment (GIA), so you may notice that the rate of sea level rise is now 0.3 mm/year higher than earlier releases. This is a correction to account for the fact that the global ocean basins are getting slightly larger over time as mantle material moves from under the oceans into previously glaciated regions on land. Simply subtract 0.3 mm/year if you prefer to not include the GIA correction. You may also note that rate of sea level rise over recent years has been less than the long-term average. This is believed to be due to the recent La Nina’s we have been experiencing, though research on this is continuing. We will soon add a plot to the web site illustrating this effect." ----------------------- I have no idea what the second paragraph means... ... but it's nice that it's optional!

I scoff as well. I live at the beach and I have seen no changes in sixty years, other than sand left or sand right.

You wouldn't notice a rise of 5cm in 20 years. That said, it looks like the sea level may be falling around much of the US coast.

That image is simply wrong. In Sea of Bothnia is the land rise about 10 mm /year due to last ice age. Most of Scandinavia have also a significant land rise due last ice age. The picture show a sea level rise. That is wrong.
A sea level rise in the middle of the ocean are probably a measurement of changed air pressure. Higher level is lower air pressures. The sea rise in west pacific is then a proof of strengthen El Nino.

Yes, it is not a big deal. 5cm er 20 years = about 25 cm per century which is approx ~10" in 100 years. That is also less than 3mm per year. Alarmist crap is boring, derivative and repeatedly shown to be untrue. Yet gullible people keep regurgitating this stuff like it was some sort of new prophecy of doom. The only interesting question left is 'Why do certain people find themselves attracted to phonied up scary stories like ducks to water?'

Humans are basically insecure. Because of this some people can use this insecurity as a way of controlling others. They imply that because of global warming, rising sea levels ect that we are all going to die, but if we follow them we will be saved. We have a very poor education system throughout the world which doesn't teach the right information for people to reason logical facts. Even in the 20th century we still sacrifice things to the gods. We waste many years getting the message through, but luckily get there in the end.

Well said, but historically this does not always work out- the fear mongers / bs marketers frequently only stop after greatly harming others. NZ sounds so awesome, btw.

So if the sea level is rising slower than the land level the image will still show the sea level rising even though the local tide gauges would see the level falling.
