I recently moved to a coastal area, and I work near the coast as well for local government. Certain portions of my work unfortunately focus on “climate change.” A BIG focus is “sea level rise.” As a result, I pay attention to this and I’m beginning to notice inconsistent reports on the amount of “sea level rise” might impact different areas of the coast. I haven’t had time to research for sauce but I plan to do so. Sea level is sea level. If it rises, it should rise consistently around the world, unless there is a weather system like a hurricane, right?

Nope, not consistent at all. For 2 years I lived in Panama around the Canal. Oddly enough, the Atlantic (Caribbean) side of the canal is always 16 feet different elevation from the Pacific side. Also, due to the corealis effect, tides and water levels at the equator will be more extreme than at the poles, since the equator moves faster around the Earth than the lands to the north.
Imagine any wheel...ferris wheel, bicycle or car wheel... the outside diameter travels faster than the inner portion because the diameter has to make one revolution in the same time the hub does...so the outer rim travels faster than the hub. Similar for Earth...the equator travels faster than lands farther north or south of the equator...and you get more water there.
Thanks!
Somebody here on GAW posted about an experiment you can try.
Fill a glass with ice water. Let it melt and see how much the water rises.
Does the experiment require that you live in a density / displacement free zone?
Yeah, but Greenland and Antarctica have most of their ice over the landmass.
Not believing the sea level hoax, but your experiment is easily refuted by that fact.
To OPs question.
No, mostly because of the coriolis effect and the moon.
The experiment works BETTER when ice is above water level, honestly. Do it. Fill a glass with ice then pour water to nearly fill - but you have to have the glacier proportion of Greenland for example below water- and mark the line. Let it melt and check the line.
What?
Read what I wrote again.
Icebergs melting will not affect sea levels because water vs ice density. Glaciers melting (like Greenlands inland’s ice and the ice over the Antarctica mountain range)
Melting icebergs will however dilute the salt level in the ocean, that might have some effect on how the sea works.
And because melting ice has temperature differential than the surround sea, the currents also might be affected. Like melting Greenland glaciers and the Gulf Stream.
What I mean is, if I understood you correctly: using this experiment to show that melting ice won’t affect the sea level is easily refutable.
Melting ice will certainly affect the sea level, but only if the ice is on land, which a lot of it are above Greenland and Antarctica. Melting icebergs might also affect the sea with lower salt levels and changes in currents.
Welcome to the flood mapping rabbit hole. The whole idea started with the brilliant idea to 'get it all digital' for local governments, globally. Since 2015 or so, lots of environment planning departments have been busy trying to predict where to draw 'red zones' with the intention to ban people from building there, or make them build houses on ginormous piles.
The idea was to create some sort of GIS dashboard that banks and insurance companies can point to, to charge extra money, or refuse applications, or something - nobody actually thought it out.
It's amazing, (and this happened in our district) when a property developer gets a second opinion from an engineer, to counter the local government maps. The council usually accept the engineer's report because it's from ... well, an engineer - not the pink haired lady wearing odd-socks who got the job of coloring in environment planning maps, while also making odd demands about grease traps that were already provided for in the building codes, but had to suddenly be bigger - but I digress.
The engineer's reports create 'steps' in the supposed 'once in a hundred year flood' levels. On the map, the proposed new subdivision is high and dry, while the surrounding properties look like a lake. (???).
Another oddity is that a recent flooding, in my neck of the woods, was proclaimed a '200-year' flood. So, the '100-year' flood map didn't predict the damage. (!).
Funny. Reminds me of a time decades ago when FIL's small real estate office was found to be in the flood plain. But right across the street wasn't. Trust me, it was odd to say the least. We had a 500 year(?) flood in 1993 up and down the Mississippi River. We joked that when a guy was hand-drawing the flood map, someone bumped his elbow and he drew a line around the office. During the 500yr flood, there was no water even close to the office, it was horseshit.😂
yep. So that corroborates my story just fine.
In my opinion, it is a scam. But hey everyone takes it so seriously when it is on a 'map'.
It’s almost as if certain entities started talking about ‘climate change’ instead of ‘global cooling’ or ‘global warming’. A bunch of nerds went to college to study ‘climate change’ because they believed it was an issue. Now, their livelihoods depend on grant money from governments and entities that are pushing‘climate change’.
What do you think would happen if their reports stated that climate change is natural or any other answer other than climate change is an issue and their studies funded by taxpayer dollars can find a fix?
I think it's dependent on the moon phase, the local crust density, the waterflows, the local air pressure, the seabed morphology, loads of things.
Even the earth is an oblate sphere so the sea "level" is higher at the equator by that metric.
Its definately higher in Canada.
Somewhere in Canada has a tidal range of over fifty feet, I seem to recall. That makes the eighth of an inch every century look a bit tame!
Here we are: Bay of Fundy, Canada
noice! But, hey muh climate change.
Never was. The Mediterranean Sea formed when the Atlantic broke through what is now the Strait of Gibraltar. The Black Sea formed when the Mediterranean broke through the Bosporus. The Dead Sea used to be part of the Mediterranean but the land lifted.
The short answer is no :
