Before 2100. Estimates on that site say as close as 2040.

It's mostly because this problem lacks visibility because we haven't been hit with the brunt of it yet. Hard to care about it when it's just some hypothetical impending problem for Florida real estate.

Well before the ice caps completely melt, when the problem is evident we will likely turn to drastic solutions like this to change things regardless of the current opinion right now.

That source absolutely does not claim that sea levels will rise 230 feet by 2100, or anything remotely close to that.

There’s plenty to be concerned about with climate change without making unfounded breathless claims.

This source claims ice caps will completely melt around 2040 and before 2100. That was what was asked for.

The 230 feet sea level rise as a result of complete melt down of polar ice caps is from OTHER sources. I can certainly provide that as well:

https://www.usgs.gov/faqs/how-would-sea-level-change-if-all-....

https://sealevel.nasa.gov/understanding-sea-level/global-sea... (more than 160m)

https://www.theguardian.com/us-news/ng-interactive/2020/oct/... (all ice caps melted by 2035)

These are not obscure pieces of data they aren't even close to unfounded they are in google and roughly the first search results. What I don't understand is the hostility here. Look up the facts yourself because you obviously didn't. It is illogical to be hostile towards something you didn't look up.

I'm sure there's contradictory evidence too, but you obviously didn't dig for that because you offered nothing to counter the evidence I presented.

All of your sources are about Arctic sea ice melting completely. If all of the floating ice shelves and sea ice melted (all of it on Earth), it would raise the level of the ocean by 1.5-2 inches [0]

For the sea level to rise 230’, all of the Antarctic ice would need to melt which will take hundreds or likely thousands of years. [1]

So no, there will not be 230’ of sea level rise in the next 75 years. That being said, the melt in Antarctica could raise sea levels by several feet by the end of the century, which would absolutely impact every coastal city on earth.
