The authors determine sea levels by dating fossilized reefs that are presently located high above current sea levels [photo below]. The paper also shows sea levels in the Red Sea were up to ~8 meters higher than the present within the past 5,000 years of the current interglacial, and up to ~12 meters higher than the present during the last interglacial. This and many other papers debunk claims by climate alarmists that recent sea level rise is unprecedented, unnatural, or accelerated. In fact, sea levels rose at a constant rate without acceleration during the 20th century, and have decelerated since 2005 to a rate of only ~1.2 mm/yr [less than 5 inches per century].
