Carbon dating evidence from the elevation of abandoned penguin rookeries (and other proxies) reveals that relative sea level (RSL) was ~30 meters higher than today across East Antarctica about 8,000 years ago (Small et al., 2025). [some emphasis, links added]
Following that highstand, RSL fell rapidly at rates of 4 to 10 meters per 1,000 years.
RSL was 24 meters above present sea level (ASL) by 7,200 years ago, 15 meters ASL by 5,700 years ago, 5 meters ASL by 3,200 years ago, and still 1 meter ASL about 800 years ago.
Another study from Antarctica’s South Shetland Islands suggests RSL has plummeted by 10 meters just in the last 2,000 years after a 15-meter highstand 9,000 years ago.
There are regions in the northern hemisphere where RSL reached similarly high elevations as they did across East Antarctica.
The southeast coast of Sweden, i.e., the southern Baltic Sea, records RSL 22 meters higher than today from approximately 7,500 to 6,200 years ago (Katrantsiotis et al., 2023).

Global sea levels were likely higher than today between 6,000 to 8,000 years ago, possibly by as much as 1.5 meters (5 feet), as massive ice sheets continued melting after the last Ice Age, though they stabilized around 4,000-5,000 years ago before modern human-caused rises, according to studies suggesting higher Holocene sea levels in some areas. static adjustment, where the land rises as the weight of the ice is removed. The claim of 30 meters higher in some portion of Antarctica is baloney. Which is the Ken Richard specialty?
Humans have NOT caused any increase in sea level something you are totally unable to prove.
Science does not prove or disprove anything.
Science collects evidence to support theories.
Evidence that human CO2 emissions are a major cause of the global warming the past 50 years is strong.
Sea level rises slightly faster during the period of global warming after 1975. Compared with the rate of sea level rise from 1940 to 1975.
The acceleration is tiny and barely seen on a tide gauge chart
Reason for that is simple: Oceans have a huge thermal inertia because they are so large and deep. High thermal inertia means the oceans resist rapid changes in temperature, acting as a massive buffer for the Earth’s climate system. This property stems from water’s high specific heat capacity (it takes more energy to heat water than air or land) and the ocean’s immense volume.
Surface ocean temperatures are significantly warmer and more variable than the global average ocean temperature.
You can thank me later for teaching you something about climate science. The “you can’t prove it” argument is meaningless in science.
I will never thank an arrogant fool who thinks he knows much more about how the climate works than he does. I don’t care how many posts you make. That doesn’t mean what you post is based on reality.
