People in the Florida Keys are starting to recognize that their islands are doomed because of global heating.

To raise their homes enough to escape flooding in the short term would cost more than they can afford. Worse than that, it would only delay the disaster, not prevent it -- the work would have to be repeated, with increasing frequency, and that would be money ill spent.

Millions of people will lose their homes due to sea level rise, and for in most cases we can't protect them for very long.

We have to focus on treating the disease, not the symptoms. The disease is greenhouse gas emission and the treatment is to curb emissions.
