New paper finds sea levels were significantly higher during past interglacials — Paper published in Quaternary Research
Study 'finds sea levels on the island of Curaçao [southern Caribbean] during the last interglacial were up to 9 meters higher than the present, and that during another interglacial period 400,000 years ago sea levels were up to 20 meters higher than the present. According to the paper, these significantly higher sea levels during prior interglacials 'require major ice sheet loss from Greenland and Antarctica.'
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].
