Rising Sea Levels
Based on recent studies, an article in today’s New York Times displays maps of major coastal cities showing what’s above sea level now and what will be above sea level in 2050. More than 150,000,000 people will be displaced by then. The before and after maps illustrate the changes in process more vividly than words and statistics. I guess in thirty years there will be a marker sticking up from the Gulf of Mexico showing where New Orleans was.
