*change* that undermines human plans represents a big challenge.
Not when the change is so slow that you have generations to decide to move away from it, or alter your investments, it isn't. Every generation typically goes into new homes. Somewhere. Eventually, a generation (not this one or any one soon) will go... "y'know honey, instead of moving here in Miami, let's check out Vermont." Or where ever.
And you know what's kind of irritating? I never hear anyone going on about sea level rise mention this little fact: Change is the hottest possible breeding ground for opportunity. Change means employment, undertakings, recovery, rehabilitation, relocation, new methods, new ideas, new crops, new businesses. And so on.
