The area that will by completely inundated by the rising ocean—and not in a century but in the lifetime of my two cats—are the American southeast, including the most populated area of Texas, almost all of Florida, most of Louisiana, and half of Alabama and Mississippi, as well as goodly portions of eastern Georgia, South Carolina and North Carolina.The author is Dave Lindoroff, and his bio says he's "a 34-year veteran, an award-winning journalist, a former New York Times contributor, a graduate of the Columbia University Graduate School of Journalism, a two-time Journalism Fulbright Scholar." How standards have fallen -- there's hardly anything scientifically accurate about his essay.
Cats live about 15 years, and global sea-level is rising about 3 mm/yr. So in the time span he envisions, sea-levels will rise only up to about 50 mm, or 5 cm, or .... 2 inches. Which isn't going to "inundate" anything.
Who cares, though, if it makes your political point? That, again, seems to be the attitude of the left these days.
This kind of alarmism does a lot of damage to the cause.
