There's the dome...you never heard of that, have you?
Marshall Islands: Concrete dome holding nuclear waste could leak
Translation: the thing is already leaking like a sieve. So, any damage done by rising sea levels will have no effect.
And, rising sea levels are certainly an issue on the Marshall Islands; the one place on earth where the innocent are paying a huge price for the sins of the guilty.
Within Decades, Floods May Render Many Islands Uninhabitable
To me, the saddest part of this story is the complete lack of concern anyone in the US had/has for the residents of the Marshall Islands. First there were 23 nuclear tests on the islands, followed by leaving behind a giant radioactive waste pit; the result of shoddy cleanup and a feeble attempt to seal it off. And now, the US territory is on the verge of becoming uninhabitable thanks to our giant hunger to devour all the resources on earth; a greed fueled by the constant burning of fossil fuels.
No wonder so many Americans go to church and beg for forgiveness. Maybe this thread will give some of them a clue to what they are praying to be forgiven about.
