I recently came across this paper

(4) Global warming and carbon dioxide through sciences

from Paul Christodoulides and Georgios Florides. I was surprised that I had not seen it before. It is indeed very comprehensive and gives references to the results of quite a number of other relevant papers. If you have the time and if you love climate science, you should go through it. Here I just show a few quotes on the results of their investigation:

ABSTRACT:

Increased atmospheric CO2-concentration is widely being considered as the main driving factor that causes the phenomenon of global warming. This paper attempts to shed more light on the role of atmospheric CO2 in relation to temperature-increase and, more generally, in relation to Earth’s life through the geological aeons, based on a review-assessment of existing related studies. It is pointed out that there has been a debate on the accuracy of temperature reconstructions as well as on the exact impact that CO2 has on global warming. Moreover, using three independent sets of data (collected from ice-cores and chemistry) we perform a specific regression analysis which concludes that forecasts about the correlation between CO2 concentration and temperature rely heavily on the choice of data used, and one cannot be positive that indeed such a correlation exists (for chemistry data) or even, if existing (for ice-cores data), whether it leads to a “severe” or a “gentle” global warming. A very recent development on the greenhouse phenomenon is a validated adiabatic model, based on laws of physics, forecasting a maximum temperature-increase of 0.01 to 0.03 °C for a value doubling the present concentration of atmospheric CO2. Through a further review of related studies and facts from disciplines like biology and geology, where CO2-change is viewed from a different perspective, it is suggested that CO2-change is not necessarily always a negative factor for the environment. In fact, it is shown that CO2-increase has stimulated the growth of plants, while the CO2-change history has altered the physiology of plants. Moreover, data from palaeoclimatology show that the CO2 content in the atmosphere is at a minimum in this geological aeon. Finally it is stressed that the understanding of the functioning of Earth’s complex climate system (especially for water, solar radiation and so forth) is still poor and, hence, scientific knowledge is not at a level to give definite and precise answers for the causes of global warming.

RESULTS:

(a) Convection accounts for approximately 67% of the total amount of heat transfer from the Earth’s surface to the troposphere, the condensation of water vapour for 25% and radiation accounts for only 8%. As the heat transfer in the troposphere occurs mostly by convection, accumulation of CO2 in the troposphere intensifies the convective processes of heat and mass transfer, because of the intense absorption of infrared radiation, and leads to subsequent cooling and not warming as believed.

(b) The analysis indicates that the average surface temperature of the Earth is determined by the solar constant, the precession angle of the planet, the mass (pressure) of the atmosphere, and the specific heat of the atmospheric mixture of gases.

(c) If the nitrogen–oxygen atmosphere of the Earth would be replaced by a CO2 atmosphere with the same pressure of 1 atm, then the average near-surface temperature would decrease by approximately 2.5 °C and not increase as commonly assumed.

(d) The opposite will happen by analogy if the CO2 atmosphere of Venus would be replaced by a nitrogen–oxygen atmosphere at a pressure of 90.9 atm. The average near-surface temperature would increase from 462°C to 657°C.This is explained easily by observing how the results of the derived formulae are affected, considering that the molecular weight of CO2 is about 1.5 times greater and its specific heat 1.2 times smaller than those of the Earth’s air.

(e) If the CO2 concentration in the atmosphere increases from 0.035% to its double value of 0.070%, the atmospheric pressure will increase slightly (by 0.00015 atm). Consequently the temperature at sea level will increase by about 0.01 °C and the increase in temperature at an altitude of 10 km will be less than 0.03 °C. These amounts are negligible compared to the natural temporal fluctuations of the global temperature.

(f) In evaluating the above consequences of the doubling of the CO2, one has to consider the dissolution of CO2 in oceanic water and also that, together with carbon, a part of atmospheric oxygen is also transferred into carbonates. Therefore instead of a slight increase in the atmospheric pressure one should expect a slight decrease with a corresponding insignificant climate cooling.

CONCLUSIONS:

Earth is a dynamic planet with a continuous variation of its climate. The present study has indicated that in their turn the atmosphere, the lithosphere and the biosphere of Earth change constantly through complex mechanisms affecting the climate. Many of these changes are unpredictable, enormous and sometimes sudden. It is certain that such natural climate-changes—both cooling and warming—will occur again and again in the future. Studying the climate record indicates that the 20th-century changes fall well within frequently seen past natural variations. It is our view that there is not yet sufficient let alone rigorous evidence that anthropogenic CO2-increase is indeed the main factor contributing towards the global warming of the 20th-century. This conclusion is supported by a mere study of the inconsistent related literature, reinforced by our analysis on the (probably more reliable and thus far overlooked) chemical CO2-records, essentially showing that one cannot be positive for a relationship between temperature difference and CO2-concentration. On the contrary, the conclusions using the adiabatic theory show that global warming due to atmospheric CO2-increase is impossible. Our study also points that even when the presence of CO2 concentration in the atmosphere was at levels much higher than today, the temperature still considerably fluctuated. Regardless of CO2’s role on global warming, CO2 is a key factor for biological activity that has generally benefited because of the increase observed in the last century. The change of CO2-concentration in the atmosphere through the geological aeons has caused adaptation in plants. At the beginning of their evolution the plants had no leaves, in the next stage they produced leaves and captured CO2 very effectively producing large deposits of coal, and in a final stage they changed their efficiency in photosynthesis to survive in a deficient environment. Palaeo-climatological data show that the atmospheric content of carbon in this geological epoch is at its minimum value. Science today still does not really offer an adequate scheme toward understanding the Earth’s complex climate system. It is therefore our belief that temperature is significantly affected by natural factors that have not yet been adequately assessed or even identified. For example, one could think of water’s role, as water is predominantly present on land, in the ocean and in the atmosphere, as well as the Sun as the main driving forces of climate. Both of these factors are rather poorly understood at present.

It looks to me that the approach that was used here to evaluate the effect of more CO2 in the atmosphere is very similar to that of Robert Holms, see his report:

The demise of South Africa’s Ferrochrome Industry

The demise of South Africa’s Ferrochrome Industry

By Lars Schernikau and Vijay Jayaraj

South Africa’s once dominant ferrochrome industry is on the brink of collapse and requires a government bailout. That decline is not because the world no longer needs ferrochrome. It is because South Africa’s leaders tied their industrial policy to a “green” agenda that undermines reliable, affordable energy and sacrifices economic strength.

What is happening in South Africa should concern every country that still cares about manufacturing jobs, supply chains and energy costs for ordinary people.

Ferrochrome – made largely of chrome ore, coal products and with lots of electricity – is not a boutique commodity. Valued for its hardness and resistance to corrosion, ferrochrome is a critical component of stainless steel, the alloy used in the making of kitchen appliances, industrial tools, passenger vehicles and construction infrastructure. It is difficult to imagine modern manufacturing without ferrochrome.

All it took was for South Africa to build a leading stainless steel industry was its domestic access to this valuable commodity. South Africa has two strengths worthy of envy: the world’s largest known chrome ore reserves and a ferrochrome production base second only to China’s. That combination should secure the competitive advantage of South African ferrochrome. Yet, the industry is dissolving.

Reporting a decline of more than 25% in ferrochrome production from 2024 to 2025 was Glencore PLC, a London-based titan in the sector that owns 80% of what was the world’s largest producer, the Glencore-Merafe Venture in South Africa.

The drop in the South African operation’s output – to 430,000 tons from 600,000 – stems from the government’s hostility toward coal and preference for technologies like wind turbines and solar panels – positions that ignore the fundamental laws of energy.

Robert Cartman, a senior analyst at Fastmarkets, predicts that South Africa’s total ferrochrome production could fall from 3.3 million tons in 2024 to a pitiful 1 million tons in 2026. At that point, South Africa ceases to be a major player. Mines will close. The expertise will migrate. The revenue will vanish.

Ferrochrome production is an energy-intensive beast that needs a steady, cheap power supply for electric arc furnaces, which won’t tolerate the intermittent whims of wind and solar. When the clouds roll in or the wind dies, a smelter operating at 1,700 degrees Celsius cannot simply “pause.”

Just as importantly, coal is not only a power source for this industry. Metallurgical coal is a chemical necessity that provides carbon as a reductant for stripping oxygen from chromium ore. Without coal, there is no ferrochrome.

There is no practical alternative to fossil fuels for the ferrochrome industry, but South Africa’s energy regime is discouraging the use of these economical energy sources and compromising the reliability and affordability of electricity.

Electricity rates have been rising for years. In 2025 alone, the National Energy Regulator approved an increase of nearly 13%, continuing a long trend of hefty hikes that stretch household budgets and corporate balance sheets.

While South African furnaces go cold, the demand for stainless steel continues to grow. However, a significant portion of the market has moved away from South Africa, allowing China to surpass it as the leading ferrochrome producer.

China understands what Pretoria has forgotten: Industrial dominance requires reliable, affordable power that can be dispatched when users need it, none of which can be provided by solar or wind. The Chinese government happily imports South African chrome ore, processes it using its own coal-fired power plants, and sells the finished ferrochrome to the world. South Africa is effectively exporting a large portion of its gross domestic product, outsourcing jobs to China and perpetuating domestic poverty.

Under the pressures of South Africa’s woke ESG (environmental, social and governance) demands, global investment firms and banks are abandoning the country’s resource sector. Coal-dependent industries in South Africa are deprived of insurance and financial services while massive amounts of coal fuel the Asian industrial machine.

It is a rigged game. South Africa tangles itself in “green” tape and “carbon” taxes to appease foreign elites, while global competitors double down on the fossil fuels necessary to build strong economies. South Africa’s newest Integrated Resource Plan 2025 (IRP2025) continues to favor wind and solar.

Electricity Minister Kgosientsho Ramokgopa recently admitted that skyrocketing electricity bills are hurting. “The Department of Electricity and Energy acknowledges that the rising cost of electricity presents a serious challenge to households, businesses, and the broader economy,” he said.

This admission is a rare moment of clarity from a government that usually deals in obfuscation. Whether promises of “policy and structural measures” to “over time” reduce the cost of electricity are ever fulfilled remains to be seen. What is clear is that the current trajectory means the complete collapse of the South African ferrochrome industry is a mathematical certainty.

Policies that aim to save industry after the damage is done are reactive, not strategic. South African leaders must pivot to an energy agenda that accepts the present reality: Coal and natural gas are indispensable for industrial competitiveness – at least until affordable, reliable, on-demand alternatives can match their performance and cost.

Putting the rise in sea level due to the warming of the earth in the right perspective.

Putting the rise in sea level due to the warming of the earth in the right perspective.

We recently made a holiday trip along the Cape coast starting in Knysna and ending up at the Weskus as far north as Velddrif. Amongst scientists who study climate change, there is much discussion about the increase in the level of the oceans and how this could affect life in and around coastal cities.

In fact, I heard some alarmists on radio claiming that by 2050 the water would rise to the level of Paarl. I decided to investigate. I show 3 graphs of places with sea level gauges on the western Cape coast.

We note an average increase of around 2 mm per annum for the western Cape. If we also include the results of the gauges on the east coast, the total average for South Africa is 1.75 mm/year. I must say that the error margin is large, on average 0.8 mm. I also suspect that at some stage new equipment was installed at most stations and that automatic recording procedures were instituted. This would make comparing current data with data from previous times somewhat complicated.

Be that as it may, let us assume that the graphs we have, thanks to NOAA, are completely correct and that we are dealing with a sea level rise of about 2 mm per annum, on average, for the western Cape. We can therefore expect a rise of 50 mm to bring us to 2050. That is 5 cm. To put this amount into some kind of perspective, I show you some pictures of the places that we visited, from top to bottom: Knysna, Brenton-on-Sea, Mossel Bay, Reebok, Jacob’s Bay, and Port Nolloth.

5 cm rise by 2050. Really? You have to laugh….

Yet, amongst our learned friends who study all the data from all over the world, which are all here:

https://tidesandcurrents.noaa.gov/sltrends/sltrends_global.htm

there are those who are arguing that there is an accelerating trend, meaning there is not only an upwards linear trend line, there is a curved line going upwards. Now, if I look at the gauge of Simon’s Bay – which seems to be the most reliable record that we have here, with the smallest error – you can see that the opposite is true: there is a distinct downturn from ca. 2015. To quote one of my friends over at the Dutch blog:

People who claim that all those hundreds of dead straight NOAA sea level lines worldwide (covering almost 200 years) are curves, are not scientists. I thought that such people were extinct after the Dark Ages, but they still appear to be present in large numbers. Insane.

Hope is what we do….. | Heart for Children

Our project of building two foster homes in Bethanie, now named “Kingdom Legae”, in the North-West, is really progressing well. I understand the building of the ablution facilities is now also completed. See pictures below. 

We are grateful for the very economic spending by Fani in building the foster homes and the progress made. Thus far, HfC has spent ca. R60000. Fani is obviously doing a very good job, supervising the building. However, we knew from the start that this would not be a simple one-year project but that we would need more time to raise the funding for a project as big as this.

To continue with the project, we are depending on your donations. Any donation or assistance with the building & furnishings will be much appreciated. To donate now:

I know that you have little power, and yet you kept my word and have not denied my name.

I so enjoyed watching this Xmas movie; I am sure many people can relate to the story as it pertains to the real problems that we all experience in life at some stage. Ourselves, we went through a difficult time this year with Annette having to go through 2 operations on her stomach, each lasting more than 5 hours. We are so grateful to God that she can now eat normally again! Looking back, we can truly say: it was a miracle. I am sure that all the prayers for her from all our friends and family (‘our angels’) had something to do with it!
