National Geographic has an interesting take on rising sea levels.
Rising Seas - Interactive: If All The Ice Melted

That was very interesting, and it validates an original statement of mine about beach erosion:

"There will always be a beach. It might not be where you want it to be, but there will always be a beach"

Good sailing on the East Coast and the North West Passage.

Wow, I really like the new inland sea/lake in Australia. We would need a channel to the sea. I wonder if you would need a permit to tie up to Ayers rock?

Only after you have first passed the fruit fly inspection.

Yeah, except that that is if ALL the ice melts, and the sea level rises by 216 feet. Worst case scenarios for global warming that I've read have the sea level rising no more than a few feet. Meaning that your beachfront home is gone, and the people who bought the "cheap" houses four blocks back from the beach now have the beachfront. Nothing nearly so dramatic as that map portrays.

It looks like I'd have to get longer dock pilings.

Then your not reading enough.

It will take time, likely not in your lifetime.

There are at least two possible reasons for the disparity.

1 - A lot of talk is time limited. They just talk about some date (e.g., 2030 or 2050, whatever) and it is not always specified. Often it is represented as if that were the end of it, and its not.
2 - If you have not read RECENT projections then you might find a big difference. Projections have been changing quickly, and all for the worse. While they MAY change back, it seems all the newer projections are for an increased rate of change.

Sea level changes might produce some novel coastal changes but the real concern for us yotties should be the change in weather patterns.
Most of the modelling predicts more frequent extreme weather events as well as shifts in traditional wind patterns and water currents. How this will effect the trillions of dollars invested in maritime infrastructure such as ports, marinas, traffic control, charts etc is anyone guess.

The people who take global warming most seriously are those who were most affected by it the earliest: the insurance industry.

No climate-change deniers to be found in the reinsurance business - The Globe and Mail

You are already paying for this, and will continue to do so, unless you wish to be uninsured.

I'm taking it seriously my insurance went up 25 percent. I pushed back giving my stellar history excellent vessel etc.... They said because of the losses last year the rates had to go up. So I'm paying for those ateliers last year. Even though I was safely sitting on 3 anchors in a protected harbor 400 miles from the major damage.

The sea has been higher and lower both in human time and before. Where I sit, there was 6 miles of ice 12,000 years ago. Darn glad its gone. The fact that it took 12,000 years and WE had nothing to do with it AND that it has been receding and still recedes seems to be lost on the folks that want to tax us on every exhaled breath. There are places in the Med that show sea levels there were many feet higher in human history. The world is all about change but it is purely human to have to blame someone for it.

All true, but this time it's happening because we have interfered with the planet so much. And it's happening faster. It's not in any way comparable
