I expect to be long gone from this earth by the time the water reaches my doorstep, unless we get a big hurricane. Then I will either be washed away or become a refugee.
As far as "sceintists" go, they are not my high priests and they tend to be as dogmatic and self-serving as any other group of self proclaimed enlightened ones. Man-made Global warming is another fad that has recently come under some serious question by many scientists. The new ice age was their holy grail in the 70s. Over population was supposed to have us all starvng by 2000. That's the problem with getting old, I remember and even believed the scientist's grim predictions. Inquiry into the nature of things is certainly admirable and has been most productive, but scientist's predictions have not been terribly reliable.
I have to say over population is a fact. The state of affairs is actually worse than is communicated. It won't be a subtle change, it will seem more overnight. However, I do believe that there is a combined effort that has led to change.
We are overpopulated, the population is not in balance with the resources available. Of course nature will take care of that in some form or another.
