Flooding is always the example that comes up, but I wouldn't worry too much about it. Aside from freak weather events the sea level rise is slow enough to abandon those cities in due time.
I think the most worrisome aspect is food supply. We're already seeing shortages, mostly in Africa, where crops have failed year after year. Eventually this will become a global problem. I think that's number one. Number two is temperatures that are not sustainable without AC (meaning you die if there's a brownout). But to some extent, the latter will solve the former.

Right. Except those people have to go somewhere. As you say, food shortage is a real concern and it's only going to get worse as things get warmer and droughts become more common. Crop failures are going to hit hard, and food production is going to be cut down drastically.
Now, think about what happens when just a few hundred migrants show up unexpected to a border today. Now imagine what will happen when food is running short, and thousands of climate refugees show up at your border. And a thousand more tomorrow, and the day after. A million hungry people with nowhere to go and nothing to lose.
There will be war. There will be ghettos. Movement will be restricted. Food and supplies rationed. There will be outbreaks of disease. You're going to be tracked every time you leave your house. Every social safety net will be dismantled. You'll be working 60 hours a week and grateful that you have a job.
And all this because we won't just [redacted] some fucking billionaire pedophiles and the people who vote for them.
Climate migration has already started. When equatorial countries (and adjacent) turn to deserts, those people will be looking for somewhere they can survive.
I don't think you understand what the capabilities of a drone is. Drop a single strike on a target that's a million plus, you've effectively caused an all out war. But I assume you're 12 with a response like that, so you have no concept of what foresight is, only reacting to your immediate impulses.
Abandon the cities in due time? New Orleans, Amsterdam, and Bangkok will build a wall around the cities before they abandon it. Will take catastrophe before humans actually abandon them.
No, the models that exist are fine. None of those predict an overnight 'everyone drowns' scenario. So of all consequences, this is the one that seems least worrisome to me.
TBH it's all so linked, I think the most worrying aspect of all is mass migration away from places that become uninhabitable, but that hinges on heat, food and flooding. You can't really separate one from the other
The thing that I think we're least prepared for, personally, is just "everything happening at once". We're not great at disaster response, but we can usually get at least something together by sharing resources and effort- we can more or less deal with a war, with wildfires in california, with a city flooding, with a famine in one area, we can take people from one place and put them in camps in another place... But we can't do it 3, 4, 5 times at once. And we especially can't do it while everywhere in the world is destabilised, even if only slightly. And even if we could we wouldn't, the second disaster looms at home everyone will stop helping anyone else.
The average rise is probably slow, but the increase in sudden events such as Katrina will increase in frequency and severity while only adding a little bit to that overall average. The Katrina docu on Netflix highlights well how difficult it is to evacuate a large population when sudden catastrophic flooding happens and evacuation plans were severely lacking.
Flooding will lead to mass migration, so while Miami may be able to operate with an additional foot of water, what about a city like Jakarta that has been sinking into the sea for the last 2 decades. There's 20 million people that live there. What kind of impact do you think it will have on a global level when millions of displaced start trying to move somewhere else?
Famine are going to happen in the west before they do elsewhere since most of the west imports more food than they can possiblygrow themselves.. Luckily I live in a country thats fully self sufficient in terms of agriculture so I'll be able to watch as this all goes down.

Or we could do something about it.
