Sea levels are falling

The average sea level is showing a increase in sea level-3mm a year since the mid 1990's. But in 2016 and so far in 2017 the sea levels are dropping. I imagine this is part of a larger cycle.

NASA satellite sea level observations for the past 24 years show that – on average – sea levels have been rising 3.4 millimeters per year. That’s 0.134 inches, about the thickness of a dime and a nickel stacked together, per year.
As I said, that’s the average. But when you focus in on 2016 and 2017, you get a different picture.

Sea levels fell in 2016, and with all of this winter’s record-breaking snowfall, I wouldn’t be surprised if they decline again this year.

This chart shows what the sea level rise since the 1990's but in 2016 the sea level starts level off and to fall, perhaps it is on it's way down or is this just normal fluctuations in the the levels?

I bet the sea level is dropping cause of all the hard work Al Gore has done.

There is an obvious correlation between the weight of the ocean's and the pressure they then exert on the ocean crust, that has an equally obvious implication for the displacement of sub crustal magma and the likely hood that some of that magma will over time be displaced toward the continental crust buoying it up slightly as the sea get's deeper, meanwhile coastal region's and low lying region's will certainly face inundation but in some area's this displacement will mean they actually become land locked.

Since the end of the last ice age Northern Europe has been rebounding (it was so heavy with all that ice the continental plate was pushed hundreds and perhaps even thousand's of feet lower than it was before the ice age, hundreds in most places and after the ice had melted the sea of course got deeper but the crust got lighter without it's ice so started to slowly rise back upward,. This however is in some places like a see-saw as in the case of Britain were northern Scotland is actually slowly rising and Southern England is sinking at a slightly higher rate than Scotland is rising.


Oh and don't forget this magma displacement will have an effect upon global volcanic behavior with more eruptions and also more earth quake's and this will result in more natural CO2 and other green house gas being released which perversely may actually then result in cooling as the increase in melt water desalinates the ocean's, this in turn will effect the mechanism called the global conveyor which the Gulf Stream is a small part of and this in turn will reduce water temperature regulation of the northern hemisphere which in turn COULD lead to an increase in cold winters, more snow on high ground and the return of Glaciers which will then swell and grow, suddenly you find yourself in an ice age and all because of global warming artificial and natural.

We are probably only in an inter glacial period anyway so it may actually turn out that human activity actually delayed the onset of an ice age already but if so it will likely only be so that we then enter an even greater glacial period.

Yeah sorry, i was fishing, thought it was a cod, was a big black plug, I will put it back, promise

is it sea level rising and falling, or is it the land?
is this a local or global phenomenon?
you have to look at the entire planet as a closed system, the amount of hydrogen and oxygen won't change, the total amount of that as water might do, and where that is might change too. is there more stored underground now? are there more clouds this year? is humidity generally higher? There's clearly more to it than just one factor.
what's the temperature of the oceans? I saw another thread that said that the temp was rising - well that means that if the pressure stays the same, the volume will have increased slightly, meaning sea levels should be rising, but you're saying they're not. so on one hand we have increased temp, the other lower sea levels, so that must mean that the water pressure is increasing to compensate. does that mean that G is rising? the earth is getting more massive?
is it to do with the gravitational pull from moon, sun, and other planets? are they maybe all a bit further away, so the pull is less, so tides aren't as high? is the earth spinning slightly faster, so more water is congregating around the equator, and less at the poles?

as you see - many factors for why the sea levels rise/fall over short periods of time. even over 30 years, there's only just a trend for rising levels. this 'blip' of downward trend does not let us off. we still need to be prepared for catastrophe, and try our best to reduce the amount that we're fluxing up our planet by.

It's interesting actually, people have been looking into why this is.

Over the past couple of decades, the oceans have been steadily rising by around 3 millimeters, a constant creep attributed to climate change. But there have been these odd blips.


And what they think the reason is, is Australia.

Australia has had much more rainfall than usual. And the geography of the country is such that this water ran into an inland salt sea, Lake Eyre, and this held a bunch of water that would otherwise have been in the oceans.


I don't think they've absolutely solved it though. But this is one action.

DB is on a diet, therefore the landmass is rising due to the lower amount of weight pressing it down.

a reply to: seasonal

what's really hard to find information on is that fact that Sea levels have been rising at a steady pace for thousands of years, long before we fired up the first coal plant. Anything you look up on the topic states something about AGW, as the internet search engines are a tiny bit biased.

Okay, we should talk to the military who are redoing all of their piers in Norfolk because the sea levels are rising. Maybe we should head down to Miami and see what is going on there.

Take the heads out of sand and stop looking for reports that enforce your beliefs. If the military is spending billions of dollars to account for it this is truth and not fiction.

a reply to: seasonal

That's just a scale matter. One month changes are irrelevant to overall.

Look!!!!

The level has been going down since March 2011!. Or not.

Sea level rise is caused primarily by two factors related to global warming: the added water from melting ice sheets and glaciers and the expansion of sea water as it warms.
NASA

Get back to us when the level has dropped down to the 60mm level, 2010 levels.

maybe Miami is sinking? maybe the piers are old and weak, maybe the foundations of the piers are sinking? if they're spending money, there is clearly an issue, but that is not cause and effect. rebuilding/restructuring piers in Norfolk does not equal global rising (or falling) sea levels.

Florida has been theorised to end up submerged for years but at the end of the day, it's still only a theory.

Looks like there was also a pretty "significant" dip around 2011 but then it went back to climbing after that. This is probably just another little inconsistency.

I put significant in quotes because it's really actually insignificant. More like "note worthy".

Things get even more complicated. If the Greenland ice melts, the sea levels in the north Atlantic will fall because the gravitational attraction of the ice will no longer keep the sea level where it is. Many people think that the ocean is like a bath tub but there are variations in mean sea level on open oceans due to gravitational attractions of various sea mounts and undersea structures. If the Greenland ice melts the Atlantic conveyor could be disrupted slowing the Gulf stream and refreezing northern Europe. This would result in large amounts of ice being formed and sea levels dropping again.
