tsunami

[Sunsettommy]

them some pretty pictures you posted there

The first link was from the NSDIDC.

The other link was from SciTechDaily

I made an honest effort to make a case based on official sources.

No you have no Rebuttal to offer, thank you.

Cheers.

No because the ice is already floating IN the ocean waters.

The ice in Greenland is not floating. It is on land, and has the potential to raise sea level by about 20 feet.

 

[Old Rocks]

1/8 inch per year ... is that what you're afraid of? ... just pathetic ... letting AI do your thinking ...

Wrong again;
Approximately 0.23 inches
The current rate of sea level rise is approximately 0.23 inches (0.59 centimeters) per year as of 2024, according to a NASA analysis. This rate is higher than expected, with the rise primarily driven by thermal expansion of seawater due to climate change.

NASA


Yes
Yes, the rate of sea level rise is increasing. Recent measurements indicate that the global mean sea level has risen by approximately 0.13 inches (3.4 millimeters) per year over the past 30 years, with the rate of increase being more than double the long-term average since 1901. This rise is primarily driven by the melting of ice sheets and glaciers, as well as thermal expansion of seawater due to climate change.

Even with only 0.24 inches per year, that equals a couple of feet in a century, catastrophic for port cities. But since the rate of rise is also increasing it is likely that it will be more than double that. https://www.bing.com/ck/a?!&&p=202b...vZi1zZWEtbGV2ZWwtcmlzZS1pbmNyZWFzaW5nLw&ntb=1

Miami International Airport is high and dry ... which port city can't take a two foot tide? ...

How expensive is a five foot berm? ... haha ... yet you still have to piss your pants don't you ... silly old fool ...

I think this group of you who are anti chat gpt look like they have practice at binding together to re enforce their personal nonsense beliefs

I am "Anti-AI" because it is inherently incorrect and leads to people believing absolute garbage.

It is not our fault that you can not comprehend science and instead fall back on a crutch instead of, you know, actually taking the time and effort to actually learn science. But your trying to claim the AI is correct when in reality it's completely wrong is absolutely comical.

This is not "re enforce their personal nonsense beliefs", this is actually understanding and comprehending science. And recognizing that AI in a great many areas is far more incorrect than it is correct.

But do not feel sad, I actually spend a lot of time in here trying to correct those that can not comprehend science. There are a hell of a lot of good videos on Youtube that are a great place to start your learning. And I am one that believes absolutely that learning should be a lifelong endeavor.

The moment you brought up the possibility of a tsunami by Arctic Ice, I knew any response other than "No" would be garbage. Just as any claims of sea level rise by melting sea ice would be absolute garbage. That ice is already in the water, the volume is already displaced, so it can have no impact beyond local ones from calving. Nothing even close enough to cause a tsunami because the volumes are already displaced.

Tsunamis are caused by massive land displacements, either under the ocean or by land falling into the ocean. The first via massive uplift/subsidence, such as the over 60,000 square kilometers of land that sank an average of 9 meters in the 2011 Japan Earthquake. Or the massive subsidence that will occur at the next Cascadia Earthquake.

Or the landslide that caused the 2025 Tracy Arm Landslide tsunamis in Alaska this year.

2025 Tracy Arm Landslide-Generated Tsunami

A landslide above the toe of the South Sawyer Glacier failed into the waters of Tracy Arm, south of Juneau, Alaska, producing a tsunami on Sunday, August 10th, 2025, at 05:26 AKDT / 13:26 UTC. No injuries or fatalities have been reported. This page may be updated as more information about the...

But a tsunami caused by ice that is already in the ocean so that volume has already been displaced? Nope, not gonna happen. Just localized waves from the calving into the water, nothing else.

what's your best algorithm so far? trai-training AI lol I'm sorry

 

[trevorjohnson83]

now that I think of it since you guys won't stop bringing it up, the ice that is floating is probably at least partially above sea level, meaning if it did all melt that it would probably in fact increase sea levels.

Put ice in a glass. Fill it to the top with water. Watch the ice melt.

Science.

 

[Mushroom]

Human thought.

To me, "AI" is no more "intelligent" than Eliza was over four decades ago. It's all still GIGO.

And as I am expecting you to have to look that up, my using GIGO should show how long I have actually been involved in computers. I literally started programming when keypunch cards were the primary way of putting programs and data into a computer.

It does not matter if it is above sea level or below it.

The volume of the ice is already displaced. For goodness sakes, this has only been understood since 246 BCE. When the volume of an object entering the water is already displaced, the net effect is zero. It's a wash. Local waves, that's all. Tsunamis are caused by massive amounts of material raising (landslide) or lowering (subsidence) the water.

And when I say "massive amounts", I am talking in the volume of tens of thousands of cubic kilometers of material or more. The Tsunami Effect was only noticeable in the Tracy Arm because it was a narrow and restricted waterway. If that had happened on say the California Coast, the effect would have been negligible.

The vast majority are actually caused effectively by material "leaving" the water. This is the case of the Tsunamis off the PNW and Japan. A huge chunk of land under water sank in moments, causing a gigantic depression that was below sea level to form. This caused the sea water to rush into that depression then continue onto land.

 

[westwall]

The 2011 earthquake was a thrust type where one plate is being subducted under the other.

The tsunami was caused by the seafloor rising from 3 to 7 meters, depending on which section of the fault you were on.

Additionally there was between 20 and 50 meters of lateral movement, once again depending on location.

A Category 3 hurricane can produce storm surges that typically range from 9 to 12 feet, but can exceed 20 feet in certain conditions, leading to significant coastal flooding and damage.

Understanding​

Storm surge is defined as the abnormal rise in water level generated by a storm, over and above the predicted astronomical tide. It is primarily caused by the strong onshore winds of a hurricane, which push water toward the coast. The height of the storm surge can vary significantly based on several factors, including the hurricane's intensity, forward speed, size, and the shape of the coastline.

Considering that 5 ft berm in a Cat 3 storm, it would not save much. And then you have the wind driven waves on top of that. And as the ocean level increases every decade, these events damage more and more infrastructure further and further inland. Not only that but the salt water invade aquifers further inland.

You have it completely backwards. As the subducting plate dives beneath the continental or ocean crust, it depresses the land because of the drag of the ocean crust against the stationary plate. This creates a stress that is only relieved when the plate being drug down rebounds, creating a tsunami.

Of course. But it is the ice on land that is melting and raising sea level.

so the ice that is above sea level presses down much like if you place a basketball in a bucket of water, when you press the ball under the water the water rises.

 

[Old Rocks]

That is a classic failed post since it didn't address my correct reply at all which was that nearly all of the ice in the North Arctic is already in the water to start with.

If your definition of North Arctic is north of Greenland.

 

[Mushroom]

This creates a stress that is only relieved when the plate being drug down rebounds, creating a tsunami.

The "rebound" is the crust falling, not rising. It is the pressure that makes it rise, the release of the pressure makes it fall.

What, do you think in a subduction zone that the crust is artificially lowered, and suddenly rises when that stress is relieved?

I do not have it backwards, you do.

 

[Old Rocks]

so the ice that is above sea level presses down much like if you place a basketball in a bucket of water, when you press the ball under the water the water rises.

When water freezes, it expands by about 10%. That is why 90% of the iceberg is under water. The ice melting will not raise the sea level on bit. In fact, the reason it won't is the same reason that Archimedes jumped out of his bath, screaming Eureka. Yes, look it up.

 

[Mushroom]

If your definition of North Arctic is north of Greenland.

The very claim of a "North Arctic" is itself nonsensical. Just as nonsensical as a 'South Antarctic".

When one moves that close to the pole and a geographic area crosses it, "north" and "south" become absolutely nonsensical. And even "East" and "West" only make sense when used in comparison to another land mass.

Such as an "East Arctic" and "West Arctic" if seen from the point of North America with the area east and west of that landmass. And even then, generally in regards to anything towards that land mass from the pole itself.

That is why if you stand on the "North Pole", literally every direction you look is "South". And the reverse at the South Pole. That is why scientists tend to use longitude references or geographical references instead.

Which he first wrote about in 246 BCE.

It always amazes me that some Greek dude that lived over 2,200 years ago understand such basic science better than many do today.
