Inconvenient Climate History: South African Sea Levels 3 Meters Higher 5,000 Years Ago
South Africa Sea Level Was Three Meters Higher 5,000 Years Ago Than Today ( Here)

By Dr. Sebastian Lüning and Prof. Fritz Vahrenholt
(German text translated/edited by P Gosselin)

Today’s topic: Sea level rise around Africa. There, the sea level is rising there like everywhere else. Already during the last warm phase, the Medieval Warm Period (WMP), sea level rose.

That makes sense because during the warm phases ice melts at the poles and high mountains glaciers. But what was the case during the Little Ice Age as the glaciers expanded?

There aren’t any tide gauge measurements from this time, but geological reconstructions have been carried out. And lo and behold, the south coast of Africa saw sea level drop during the Little Ice Age. See Scott & Lee-Thorpe 2004:

There is good evidence for a number of environmental shifts during the last 2,000 years, but the most noteworthy event may be the climatic fluctuation during the Little Ice Age (LIA) period. Evidence for a lower sea level on the southern coast during its earlier phase (1520 or 1570 AD) may be a reflection of widespread anomalous conditions during this phase (Marker 1997).”

Also on the west coast of South Africa, we find a small surprise. Five thousand years ago sea levels were three meters higher than they are today. This is nicely documented by Carr et al. 2015 in their Figure 7:

Sea level of the west coast of South Africa during the past 9,000 years (BP=years before present). The solid curve applies here (not the dashed line). Source: Carr et al. 2015.

Next, let’s move northeast to Mozambique. There, scientists Achimo and colleagues find that Maputo Bay already reached today’s levels 5,000-7,000 years ago:

The complete picture of Maputo Bay patterns with its modern sedimentary environments including Inhaca Island may have evolved when the sea level has stood close to its present level around 7,000 – 5,000 years BP, after which the Maputo Bay became more or less stable.”

A sea level drop between 800-1300 A.D. at Mozambique was documented in Sitoe et al. 2017 (see their Fig. 5).

Sea level rose again gradually after the year 1300 A.D. but hasn’t reached by any measure the level seen in 800 A.D.

Hansen, father of ‘global warming’, calls renewables a ‘grotesque idea’

Anthony Watts /
Dr. James Hansen, writing about his 1988 senate testimony 30 years ago in an op-ed in the Boston Globe, said some very strong things when it comes to the pie-in-the-sky renewables schemes.

He starts off with:

THIRTY YEARS AGO, while the Midwest withered in massive drought and East Coast temperatures exceeded 100 degrees Fahrenheit, I testified to the Senate as a senior NASA scientist about climate change. I said that ongoing global warming was outside the range of natural variability and it could be attributed, with high confidence, to human activity — mainly from the spewing of carbon dioxide and other heat-trapping gases into the atmosphere. “It’s time to stop waffling so much and say that the evidence is pretty strong that the greenhouse effect is here,” I said.

This clear and strong message about the dangers of carbon emissions was heard. The next day, it led the front pages of newspapers across the country. Climate theory led to political action with remarkable speed. Within four years, almost all nations, including the United States, signed a Framework Convention in Rio de Janeiro, agreeing that the world must avoid dangerous human-made interference with climate.

Sadly, the principal follow-ups to Rio were the precatory Kyoto Protocol and Paris Agreement — wishful thinking, hoping that countries will make plans to reduce emissions and carry them out. In reality, most countries follow their self-interest, and global carbon emissions continue to climb (see graph at bottom).

But his finish is quite something, and is sure to raise some eyebrows in the green sector:

The notion that renewable energies and batteries alone will provide all needed energy is fantastical. It is also a grotesque idea, because of the staggering environmental pollution from mining and material disposal, if all energy was derived from renewables and batteries. Worse, tricking the public to accept the fantasy of 100 percent renewables means that, in reality, fossil fuels reign and climate change grows.

BOOM!
