In the past, major climatic changes occurred without human intervention. The sea level was not spared either. New investigations prove this impressively. Even without industrialization, this was about 6,000 years ago up to three meters higher than today.
The global climate has always been subject to massive fluctuations in temperature. Ice ages are followed by warm periods and these ups and downs will continue in the future. This is also noticeable in the sea level, which according to research is also subject to large fluctuations. According to studies, this has increased by an average of 1.56 mm/year since 1900. So we’re talking about 15.6 cm in a century. That sounds like a sharp increase, but there are said to have been much more extensive changes in the past.
For example, from 9,000 to 8,000 years ago, the sea level in the East Vietnam Sea rose by 29 meters – from -35 m to -6 m compared to today. That is 2.9 m per century or 29 mm/year. From 8,000 to 6,700 years ago, sea level then rose another 7.5 m. At that time (6,700 to 5,500 years ago) the sea level was 1.5 m higher than today. This is shown by a recently published study (Sequence stratigraphy and sedimentary processes since the last glacial maximum in Nha Phu Bay and adjacent shelf, central Vietnam).
Historically huge increases proven
Another recent scientific paper (a doctoral thesis) concludes that in the centuries ago around 14,500 years ago, global sea levels rose by 13.5 m (45 mm/year) in 300 years and by as much as 6.5 m in 140 years (>46 mm/year) would have increased. Sea levels eventually reached levels up to 3 m higher than today during the Holocene Sea Level Rise. (Also compare the article in the science magazine Scinexx). Sea levels along the coasts of New Zealand were 1.2 to 2.5 m higher than they are today for much of the last 7000 years before falling to current levels in the last millennium. This is probably due to the fact that the planet experienced a cold period in the meantime, which led to the build-up of glaciers and the strengthening of the ice sheets on the polar caps. It is not for nothing that the current melting of the glaciers is causing remnants of long-forgotten days (such as the famous glacier mummy “Ötzi”) to reappear.
Coastal regions have always been endangered
From a human point of view, such climatic changes have always caused challenges in the past, but human civilization has been able to continue to develop. Our problem today with regard to sea level rise is primarily that there are no longer just a few tens of millions of people living on this planet, but more than eight billion. Hundreds of millions of them live in coastal areas, making them more vulnerable to flooding. So the main problem is not the fluctuations in sea level itself, but rather the fact that mankind has mainly spread to the coastal areas.
Ultimately, the obvious fact remains: the rise or fall of sea level had nothing to do with CO2 levels in the atmosphere in the distant past, and it will remain so. Earth has experienced significantly higher sea levels—and significantly lower ones as well. The opinion of Ms. Klima-Greta and the globalists behind her, who swindle billions with the certificate trade, doesn’t matter to planet earth.
