The Arctic ocean freeze and thaw cycle over enormous amount of ice, around 10,000,000 square kilometers every single year.
But we don't see the Greta Gore floods wiping away the beachfront properties every. Why?

The surface of the seas in the Arctic freezes during fall and winter, forming ice packs. The ice packs thaw during spring and summer, and become seawater again. This seasonal cycle between seawater and ice pack has no effect on sea level. It's not adding to (or subtracting from) the amount of water in the oceans.
Sea level doesn't change when seawater at the surface of the ocean freezes and forms ice packs. Sea level doesn't change when the ice packs melt and revert to seawater again. It's in accordance with Archimedes principle of buoyancy.
No matter how thick the pack ice (or ice packs), this is frozen water that's floating on the sea. It's actually above sea level. It displaces or "pushes upwards" the same volume of seawater that equals its mass. You could be in the Arctic and looking upwards at pack ice that is so thick that it rises above you. But that doesn't change the sea level where you would be, at that place in the Arctic, and it doesn't change the sea level anywhere else around the world.
BUT... when ice sheets and glaciers, in Antarctica and Greenland (the two biggest) and other places melt, the meltwater flows into the ocean. Or the glaciers themselves, lubricated by meltwater, slide off the land and into the ocean, becoming ice bergs. These are processes that move water from land areas to oceans and so, increase the amount of water in the oceans—and that causes sea levels to rise.
To model what happens when ice sheets on land or glaciers melt or flow into the sea, the experiment would have to start, not with the ice cube already floating in the water in that measuring cup, but with the ice cube—having been taken from the freezer section of the refrigerator across the room—in the hand of Greta Thunberg before she drops it into the water. That would cause the water level in the measuring cup to rise, proportionate to the mass of the ice cube. Ergo, sea level rise.[This message has been edited by rinselberg (edited 01-23-2023).]

Has anything Al Gore, the charlatan, the quack, proven true. Has any green scare promise been proven true ?
Whah whah whah. The Planet's temperature will be one degree higher in 100 years. What is the ideal temperature that the gawds think is ideal ?
There are lies, damn lies, statistics, and false science.
I don't know how you believe in science. I view it as a theory, not a fact.
What gets me is why don't people question lies, damn lies, statistics, and false science. Scientists always question.
I always question government.

Wichita asked the question.
That's why when I posted "the same s**t again" here, I started with Wichita's latest remark in the Quote format.
I don't want Wichita not to understand what really is a simple concept.
Every time I explain it again, I think my explanation becomes more complete, and more clearly worded. "Practice makes perfect."
I don't want to PM him about it. That just seems... I dunno. I'd rather post the explanation again, as I just did, and hope he reads and understands it.
It's important to remember that the Arctic (proper) is an ocean, whereas Antarctica is a continent. That could be what's confusing him. He might not have even realized that his latest remark, which he framed as a question, goes right back to this very same "ice cube in a measuring cup of water" meme.[This message has been edited by rinselberg (edited 01-23-2023).]

You want to take a stab at explaining it to him?
