Fifteen more new studies published in 2024 document meters-higher sea levels across the world during the Mid-Holocene, when CO2 hovered near 260 ppm.<\/strong><\/h4>\n\n\n\n

There were 45 studies published from 2022 to 2024 indicating sea levels were approximately 2 to 3 meters higher across the world about 7000 to 4000 years ago before declining to today\u2019s levels.<\/p>\n\n\n\n

For a full database of over 150 studies, see the updated \u201c2m Higher Holocene Sea Levels<\/a><\/strong>\u201d on the No Tricks Zon<\/strong>e right side bar.<\/p>\n\n\n\n

\u201cThe Holocene transgression began flooding the extensive continental shelf offshore BAH around 10 ka BP, progressively separating Masirah from the mainland through channel formation between 9.5 and 8.0 ka BP. It then inundated the present-day BAH peninsula around 7.7 ka BP, reaching a highstand of 2.5\u20133.2 m above present sea level by 6.0 ka BP (Mid-Holocene Highstand; MHHS), before gradually declining to the current level<\/strong>.\u201d<\/em><\/h6>\n\n\n\n
