Will your house be underwater?
There are some Google-based sites where you can see what happens if the ocean level rises by the amount that you specify. Here is one

There are better ones using Google Earth too.
I took a look at what a 2 meter rise would do.
Interestingly, most of the West Coast seems okay, except for a few specific spots (the Delta and part of the Peninsula in NorCal, some of the bays in Oregon, some islands in Puget Sound, etc). For the most part, either our coastlines are steep-ish, or you can't build right on the ocean's edge anyway.
However, significant parts of the East Coast are submerged, especially down south (NC SC FL LA etc) and also some Northeast and Mid-Atlantic spots (including some that I don't really think of as "coastal", like a good bit of New Jersey). And presumably people living on some inland waterways.
So, if or when the ocean rises 1 meter, then 2 meters, a lot of people are going to lose their largest possession. I think tens of millions of people. There's no way we can surround the East Coast with levees.
Are you one of them? Do you think this will affect you - not necessarily that your home will be underwater in your lifetime, but as ocean levels rise presumably you're more vulnerable to flooding and un-insurable, and maybe your property value falls since "owning" the property is now effectively nothing more than a "lease", no bank will write a mortgage on it, etc.
If you're not one of them, do you think you will be affected anyway? Will a coastal road have to be moved inland, requiring eminent domain seizure of your property? Will your beaches be submerged, making your region less desirable (asking all of you Martha's Vineyarders out there).
What, if anything, do you think we can do to protect our coastline? Maybe we put in a thousand-mile breakwater?
Oh, yeah, Stijn, how will you accomodate the entire country of Holland as they relocate to Belgium? Do you like the Dutch?
I know what I'm doing. I'm going to make sure my kids and I visit Venice several more times in the next few decades, while it is still there.
