The belief that modern sea levels and sea level change rates are unprecedentedly high takes another hit.<\/em><\/strong><\/p>\n\n\n\n

Per a new study, sea levels were ~9.5 m higher than today about 8000 years ago (White Sea, northwestern Russia), then fell to ~7 m higher than today by around 4000 years ago.<\/p>\n\n\n\n

From that point in the Middle Holocene, the sea levels plummeted (by 7 m) to the present. Today\u2019s sea levels are likely the lowest since the last glaciation in this region.<\/p>\n\n\n\n

Early Holocene sea level change rates ranged from 35 to 100 mm per year. Compare this to the 1.56 mm per year change rates experienced from 1900-2018 (Frederikse et al., 2020<\/a><\/strong>).<\/p>\n\n\n

<\/p>\n\n\n\n

This study (Kublitskiy et al., 2023<\/a><\/strong>) also reveals the modern sea ice coverage in this region is the highest it has been (~4 mo.\/year duration) in the last 6000 years. There were Holocene centuries (e.g., the Roman and Medieval Warm Periods) when this region was sea-ice free year-round (~0 mo.\/year).<\/p>\n\n\n
