What scares you the most about it?
Besides (or included in) all the "poorly undertood" factors, a concern is sudden sea level rise.
If sea level creeps up gradually, people will have time to deal with it. But what if the ice on Greenland and Antartica should melt or slide into the oceans quickly, causing sea level to rise tens of meters in just a few years? Coastal cities underwater, Miami 50 miles out to sea, hundreds of millions of refugees seeking higher ground.
I'm almost old enough to say "can't happen in my lifetime," but our kids could see it happen.

As long as it doesn't start a heating-spiral towards conditions on Venus the human race can survive with even 5 billion dead. Further as long it doesn't trigger an all shooting war with nuclear and biological weapons which could potential kill off the human race or reduce the survivors to a functional iron/stone age, while living in a toxic wasteland. So welcome to the induction problem - it is impossible from the present to foresee the future as such. In general this one applies to such problems as seen from the individual level: Even I as a Godless atheist/agnostic can understand the wisdom though religion is bad.  |

I read once that about 80% of humans live within 50 miles of a sea coast. If the people who live within 1 mile of a coast have to move inland due to rising sea levels, there will be a major economic hit. Their homes and land will have no value. Pretty scary.

I have seen a similar number somewhere and have already recommended twice that people who were talking about moving to the coast be sure that they buy at least 100 feet above current sea level, and not near the edge of a crumbling bluff (like in nearby Santa Monica or Malibu). (I don't go around preaching -- they were already looking at property.) |

How about being 360 degrees with around the coastline? That sounds bad, but much of Hawaii is high enough to be out of the danger zone. Worst case scenarios, where all the glaciers and snow packs melt and all that water flows into the oceans estimate a sea-level rise of about 100 meters. How much bigger would Pearl Harbor become? |

Well, I hope this works, because I still don't get how to reply to a specific post. So, assuming (not making I hope you know what out of me and whomever) I'm okay and in the right place, I do believe you're correct, Raybar, in that I don't have much to worry about in this lifetime (whatever is left of it). I live high up. The folks living in the tsunami and flood zones along the coasts, that's not too good. In fact a short time ago, there was an ediorial in our local paper about development planned for the Kakaako area (along the south coast -- eear Waikiki area, etc.) that in time it will be sea level. For me, I'm not worried just as long as reincarnation doesn't exist. I, for one, have no desire to come back anywhere on this planet.
