Can someone tell me whether sea level rises are still a concern and if so, why no one seems concerned?

When I was a kid that was the big scary climate change thing. I know it's maybe only 50cm but that's still problematic for lots of real estate... isn't it?

Like just the other day I visited an expensive apartment that would've been maybe 50cm above sea level.

The rising of the sea is astronomically slow, so there's a lot of denial about it. It's already a minor (maybe moderate?) problem here on the east coast of the US. Boston, NYC, and Miami are already seeing more flooding during storms than they saw historically.

But if there's someone who is willing to pay for a waterfront property despite the risk, then there will always be someone willing to sell it to them.

But here in Boston, we're finally starting to see new construction projects taking future sea level rise into account: https://www.baysideupdate.com/#:~:text=By%20raising%20the%20Project%20Site,and%20protect%20the%20surrounding%20neighborhood

It remains a concern; and is proceeding at a few mm per year.

I'm seeing it affect local planning in a meaningful way where I live, and is demonstrably affecting property values in low-lying areas.

I guess part of my question was whether it's progressing more quickly than previously anticipated given that climate change is progressing more quickly than previously anticipated.

My local council has a 100 year plan to mitigate the impact.

The problem isn't just the level the seas rise to because of melted glaciers; it's the increase in chaos in weather systems - storm surges like the ones blasting mansions off of cliffsides in cali, crazy flooding, more hurricanes of increased intensity, etc

It's a concern already for low-lying atoll islands like those in the Maldives and Tuvalu. Half of Tuvalu's capital city is expected to be flooded by 2050, but they've been seeing the effects for years unfortunately.

It really depends where you are though - my town is at around 100 m elevation and about 80 km inland. When I was a kid, my mum used to have nightmares about tidal waves coming over the horizon because she was so scared of sea level rise.
