When alarmists warn of rising sea levels, they forget to point out one important fact: Current sea levels are the lowest they’ve been in nearly 8,000 years, according to two newly published studies. At that time it was two to six meters higher than today. And that too with a much lower CO2 concentration in the air.
Did you know that about 6,000 to 8,000 years ago, during the middle Holocene, sea level was two to six meters higher than it is today, depending on the region? Considering the fact that we’re actually at the end of a cold period, it’s really not that surprising. Even more: At the time, CO2 levels in the atmosphere ranged from about 265 to 280 parts per million (ppm), compared to about 420 ppm today. But it was much warmer than today, despite the much lower CO2 concentration in the air And the polar ice caps also showed less ice cover than at present.
Among other things, a study in central Patagonia in Argentina determined the then significantly higher sea level. According to this, it was about six meters above the level at which it is now. This is quite a difference. The data also shows that sea level rise in the local area was up to 110 meters lower during the last ice age than it is today, It increased significantly as the Earth warmed until about 8,000 years ago and has since seen a slow decline to today’s levels.
Japanese figures also confirm this trend.
Similar data can also be found in the Northern Hemisphere. There, recent study data from Japan suggest that during this middle Holocene period, relative sea level was about two to five meters higher than today, about 1 to 1.5 meters above present sea level during the Medieval Warm Period. level, and then gradually dropped to today’s level. In other words, here again the data show impressively that sea level is falling rather than rising.
On the other hand, these two studies also show that global warming in our time is really only a correction and that sea level rise again as a result of the melting of ice caps and glaciers is not significant. These two studies also suggest that CO2 cannot be identified as the primary factor for higher temperatures. Because how is it that 6,000 to 8,000 years ago not only was the average temperature much higher than it is today, but sea level was also a few meters lower than it is today?
