I don't know if this is the canary in the coal mine, or just an artifact of poor original urban planning, but Miami beach has a road raising project to prevent flooding at high tide. link about street flooding miami beach This is not without controversy since road work diverts flooding water runoff.I've been to beaches in FL, SC, NC, ME, CA, OR over my 56 trips around the sun and haven't seen any significant sea level change. Obviously people like Obama and Zuckerberg aren't worried or they wouldn't have spent tens of millions on seaside mansions/properties.
Old basketball axiom... "watch their feet not their head", so they don't fake you out on defense with a head fake. Ex President Obama considered himself a ball player. I rewrote it to be watch what he does, not what he says, because he made good speeches.I believe it was JR who used to say "watch their feet not their lips" or something to that effect.
The next ice age is coming, but i can't tell you exactly when.I'm old enough to remember "the next ice age is beginning" all over news, magazines, and books. It isn't clear that humans actually understand what's going on, but it does seem that our outsized hubris makes us believe various theories we've made up from incomplete data and knowledge.
Again rising temperature or ocean level is an objective fact... the real question is what do we do in response. I am pretty sure hobbling the fossil fuel industry is not the optimal solution. The world needs the wealth from inexpensive energy to adapt.
