Solar Magnetic Field Change and Its Impact on Earth’s Global Warming

The now generally accepted paradigm attributes the Earth’s global warming to greenhouse gases, a significant portion of which is anthropogenic, primarily from the extraction and burning of fossil fuels and intensive agricultural practices. The hope is that it is within humanity’s ability to limit this biosphere-threatening process by regulating the mentioned activities. This article argues that processes on the Sun have partly or entirely caused global warming in the Earth’s atmosphere over the past 70 years. Global warming is likely a consequence of streams of positively charged, high-energy particles emitted by the Sun, mainly during the “rise” phase of solar activity when the phenomena on the Sun’s surface are associated with the growing magnetic field. Part of the flow of high-energy radiation reaches the Earth. It penetrates deep into the Earth’s atmosphere, creating an increased content of ions that serve as condensation nuclei around which water vapor forms drops. Condensation nuclei increase cloudiness in the lower atmosphere. The upper surface of clouds and fog partly reflects electromagnetic solar radiation into space. It does not reach the Earth’s surface, which leads to a decrease in the temperature of the surface and, hence, in the temperature of the ground air heated by the surface. When the solar activity decreases, as observed in the last 70 years, the reverse process occurs – the high-energy fluxes of corpuscular radiation decrease, the ionization of the air in the Earth’s atmosphere decreases, the cloudiness decreases, and more solar electromagnetic radiation reaches the Earth’s surface, increasing the temperature. An additional argument for the presence of high-energy radiation that penetrates deep into the Earth’s atmosphere and even reaches the Earth’s surface is the high statistically significant correlation between the fluxes of such radiation recorded by the GOES series satellites in geostationary orbit (36,000 km above the Earth’s surface) and human mortality from the deadliest diseases. The bad news is that if the described mechanism is the leading cause of global warming, there is not much humanity can do to protect itself and the biosphere. Humanity’s efforts (the International Energy Agency estimates global clean energy investment at USD 3 trillion for 2024) should be redirected towards increasing the planet’s reflectance of solar electromagnetic radiation.
