 Do We Need To Do Anything Now?

― To get an overview of the issue, read

1. Look at the maps showing lands vulnerable to sea level rise.

2. Read the abstracts for Cost of Holding Back the Sea , the barrier Island article , and Maryland Law Review without downloading any of the full pdf reports.

3. Read the background section on pages 1-11 of "Cost of Holding Back the Sea" , figures and tables only for pages 12-24, which summarize the study, and conclusions on pages 24-26.

4. Pages 3-8 of the barrier island article , figures and tables only for pages 9-15, then read implications section on pages 15-17.

5. Parts I and II of the Maryland Law Review article.

6.

If you are interested in saltwater intrusion, skim reports mentioned above that address this issue.
