besides the fact that 40% of the world's population lives near the coast - and that 2-3 feet of sea level rise is not a uniform "the tide used to be 8 feet, now it's 11 feet" - Entire islands in the pacific will disappear - How do you think global trade works? What do you think happens to ports? AMOC collapsing (a byproduct of sea level rise) will have profound effects on climate, despite this author claiming without any evidence whatsoever that "actually it isn't a big deal."

Ports get retrofitted, redesigned, and rebuilt. The AMOC collapsing is a serious thing, but I'm not saying climate change isn't real or isn't a threat. My original point is that three feet of sea level rise is manageable, if expensive. Simply that, nothing else.

If you draw the line at the year 2100, things are uncomfortable but maneagable. If your horizon is 2300 or 2500, you get a different story. But you would hope that in tha sort of time frame, we have time to adapt.
