Let me guess! Sea levels will rise 2 ft +/- 2.5 ft right?
The projections are all over the place (thus why I was so vague) but I don't think they went quite as far as to have error bars that went into the negatives. Not that there's anything wrong with that.
More like +5/-1
+5/+1 more like. The sea will rise, but it's just a question of how much.
