CO2 “only affects a small range of long-wave re-radiation from the surface of the Earth,” and there “seems to be no connection between carbon dioxide and the temperature of the Earth.” − Harris, 2023
Some key points from the paper include:
• Past and modern climate change is driven by solar cycle (Milankovitch) variations and their affect on ocean circulation and heat transport.
• Throughout the last hundreds of thousands of years, temperature changes precede the lagging changes in CO2.
• The UN IPCC position that atmospheric CO2 is the cause of the warming since the onset of the Industrial Revolution is only an assumption that is “not consistent with studies involving changes in temperature in rural areas of the northern [NH] hemisphere.”
• The natural 23 thousand year (23 ka) Milankovitch cycle has begun to reduce insolation in the NH “starting in 2020,” and this “heralds the start of the next glaciation.”
• CO2 is essential for life on Earth (photosynthesis), and a reduction in CO2 would be harmful to the biosphere. On the other hand, there “seems to be no connection between carbon dioxide and the temperature of the Earth.”
