A recent report from some global warming alarmists claims that the sea level has risen 9 inches in the last fifty years or so, but how did they measure that, and how do they know that the crust of the earth in places hasn’t sunk 9 inches rather than the sea level having risen? Yet by this logic, some might ask then why aren’t the hundreds of sites of submerged ruins worldwide because of this tectonic mechanism, the reason that vertical tectonic movements of hundreds of feet would be reflected by vertical fractures in the geologic strata though not seen, the sea level not risen since circa 1400 b. c.
