Ah, but how would one get to the marinas if the roads and lands they are connected to are flooded.

Apparently, Earth's sea level has gone 8 meters higher than it is now, and 135 metres lower than it is now in the last 200,000 years:

I'd call that significant.

Yes the land under the ice will rise slowly as the weight of the ice is removed by melting and the liquid water flows downhill towards the sea level. But the mass and volume of water that melts and flows into the sea will raise the sea levels.

The northern part of the Jutland of Denmark is rising more than the southern part because the southern part was depressed by less depth and weight of the ice flow during the last ice age.

Re: US coasts sea level rise 10 to 12 inches by 2050

Almost 100% of so-called sea level rise is caused by the shifting of the Earth's tectonic plates. This is a natural phenomenon over which humans have no control. Kansas was once at the bottom of an ocean. So was Mt. Everest.

Every molecule of water that was on the planet is still her today in three forms solid liquid and gas, except for a small quantity the has been broken down into hydrogen and oxygen experimentally.

I ask people if all the ice in the arctic melted how much would the sea levels rise? I get answers from 2 to 20 feet. The answer of course is zero. All arctic ice is floating and therefore is already displacing an amount of water equal to its weight.

While it's true that arctic ice has been melting at a relatively fast rate in recent years the snowpack has increased dramatically on the Antarctic Contenant. Its Ross Ice Shelf is the size France, but it too is afloat, as are the dozen or so other ice shelfs in Antarctica.

Man-made global warming has been soundly debunked. "Climate Change" has been substituted as the woke crisis of the day. The woke folks have had to admit that this is a natural occurrence which has gone on since the planet was formed.

So let me get this straight. If climate change is a natural occurrence why are humans suggesting that man-made efforts will have any effect on the inevitable? Good luck. It's not nice to fool Mother Nature.

Re: US coasts sea level rise 10 to 12 inches by 2050

Just on TV tonight-California ocean levels to rise 1 foot on next 30 years. What are the communities to do ?

So that is 304 mm in 30 years, or 10 mm a year.

That is 10 times the current level of rise, on the California Coast, on average.

California coast sea level trends run from -0.70 mm/year in Cresent City to 2.2 mm/year in San Diego, with most of the state in the 1 mm/year category.

No specific details on how this is predicted to occur, and by what level of certainty, is provided to the 30 million who live here.

Ocean rise gets to 10x the current rise amount on average. But many websites call it eye-opening anyway.

For global sea level trends might I suggest.

What is your 500million year graph trying to show that can't be explained? The use of a quasi-logarithmic scale distorts the results, so not much can be made of the graph.

If you expand many of the earlier sections similar to the last few hundred years, you will see similar flat sections followed by changes.

I agree.

Except, it's common for one side of the discussion to chastise the other for incorrect use of terminology when it supports their position but happily makes the same logical mistake to prove their point.

So now when the news stories and climate activist wax on after a hurricane/tornado/forest fire/heat or cold wave how this is climate change, will you chastise them also for incorrect and misleading terminology?

Weather forecasts are quite good for the next 1-3 days. By the time you get a week out they are little better than educated guesses.

Ironically, climate modeling is the opposite. Trying to look at a few years, a few decades, even a few centuries can be incredibly hard to predict but expand that out into the 10's of thousands of years and you can see the patterns.

Problem is humans haven't been impacting the climate for long enough to get a good handle on what is normal variation vs caused by humans...even more important, what humans can do to impact it.
