- Sea-level rise due to global warming
Analysis of historical solar cycles confirms the existence of both the 11-year short-term Schwabe cycle and the roughly century-long Gleissberg cycle.
Moreover, by noting the inverse relationship between solar activity and the formation of atmospheric radiocarbon, it is possible to identify a significant 6,000-year cycle in solar activity through the analysis of carbon-14 levels preserved in tree rings from the last 12,000 years.
When solar activity intensifies, the solar wind strengthens, shielding Earth from galactic cosmic rays and reducing the production of radiocarbon. Data indicates that during the Ice Age, solar activity was weak, leading to higher levels of atmospheric radiocarbon. However, around 12,000 years ago, a sudden surge in solar activity triggered global warming, causing the melting of massive polar ice sheets. This resulted in a rapid sea-level rise of over 100 meters, which severed the Japanese archipelago from the Asian continent. During this period, islands in the Pacific and Atlantic oceans likely submerged as well. It is plausible that legends of lost continents such as Atlantis, Lemuria, and Mu are linked to this dramatic rise in sea levels. Later, about 7,000 years ago, another peak in solar activity led to further warming and the ‘Jomon Transgression’ in Japan. This warmer climate facilitated the development of regional cultures and the flourishing of the world’s four great ancient civilizations.
Subsequently, during a 3,000-year period of declining solar activity, global temperatures gradually dropped, leading to Little Ice Ages such as the Spörer and Maunder Minima. From around 1700, sunspot numbers began to increase following the 11-year cycle; solar activity intensified, and temperatures rose accordingly.
As shown in the enlarged view of the red-outlined section, there is a sharp increase in solar activity starting from the 1900s.
This sharp downward curve is strikingly similar to the trend observed approximately 12,000 years ago, suggesting the possibility of a sea-level rise exceeding 100 meters in the future. The recent rapid rise in sea levels cannot be attributed solely to greenhouse gases. Henrik Svensmark, director of the Center for Sun-Climate Research in Denmark, points out that solar activity plays a significant role in global warming. The historical record of solar activity and glacial melting bears witness to this fact.

Considering the changes in solar activity over the past 12,000 years, the rapid decline in radiocarbon levels since 300 years ago—namely, the intensification of solar activity—is expected to persist for the next several millennia.
- Civilizational prosperity facilitated by global warming
Historical evidence confirms that periods of intensified solar activity and subsequent global warming correlate with the flourishing of human civilization. Following the two distinct cooling periods known as the Spörer and Maunder Minimums, solar activity began to resurge in the mid-1700s. It was during this period that the Industrial Revolution emerged in Britain, and in the mere 250 years since, modern civilization has rapidly advanced to its current level of scientific and technological sophistication.
- Solar Activity and the Great Global Purification
Conversely, major global incidents and catastrophes have tended to occur during the first half of the 100-year cycle, specifically during the phases within each 11-year cycle when sunspot numbers increase (periods of intensifying solar activity). In particular, during the first half of the 1900s, when sunspot activity surged rapidly, World War I, World War II, and the Pacific War broke out, leading to a period of radical global transformation.
- Solar Activity and Its Impact on Pandemics
Furthermore, it was during this same period that the 1918 global pandemic of a new strain of influenza (the Spanish Flu) occurred, resulting in an estimated 100 million deaths worldwide, including projected figures for the African continent.
The past three major influenza pandemics—the Spanish Flu, Asian Flu, and Hong Kong Flu—all emerged during the peak years of the 11-year solar cycle. Furthermore, during the first solar maximum of the 2000s, the SARS coronavirus spread globally, infecting over 8,000 people and resulting in more than 700 deaths across 29 countries.
During the second solar maximum of the 2000s, an Ebola virus outbreak that originated in Sierra Leone in 2014 caused more than 11,300 fatalities. Simultaneously, the MERS coronavirus, which emerged in Saudi Arabia, had resulted in 2,428 infections and at least 838 deaths across 27 countries as of May 17, 2019.
Additionally, a new Ebola outbreak in the Congo starting in July 2018 saw 3,481 infections and 2,299 deaths (a 66.0% fatality rate) by July 3, 2020.
The Ebola outbreak that spread from Sierra Leone in 2014 had a fatality rate of 39.5%, whereas the new strain that emerged in the Congo in July 2018 shows a significantly higher virulence, indicating it is a distinctly different type of the virus with increased toxicity.
The Royal Observatory of Belgium has announced it is certain that a new solar cycle commenced in December 2019.

Simultaneously, the novel coronavirus (COVID-19), which originated in Wuhan, China, in December 2019, spread across the globe with staggering speed. In just over 20 days since the first death was confirmed on January 19, 2020, the death toll significantly surpassed that of the entire two-year SARS outbreak. Consequently, on March 12, 2020, the WHO finally officially declared a global pandemic.
The increase in the number of domestic COVID-19 infections and deaths was found to be in direct alignment with solar activity.
As of February 15, 2026, the WHO reports 779,142,314 confirmed cases and 7,111,892 deaths worldwide (a fatality rate of 0.913%). This infectious disease, which emerged in tandem with the onset of the new solar cycle, is now trending toward its conclusion.
＊Cumulative COVID-19 cases and deaths（JHU⇒WHO）
On the other hand, the Spanish Flu pandemic of the early 1900s was caused by the H1N1 influenza virus. It is estimated that between 50 and 100 million people died out of a global population of 1.8 billion, representing a vastly different lethality rate from today’s viruses. If the H5N1 avian flu currently circulating among animals mutates into a novel human influenza, the mortality rate could exceed 50%. In our modern, interconnected world, a pandemic with the same infection rate as COVID-19 could result in over 400 million deaths out of a global population of 8 billion. This would trigger unprecedented global panic and catastrophic economic collapse, with starvation due to food shortages surging alongside pandemic fatalities. Mankind is facing a crisis unlike any encountered before.
On May 8, 2023, COVID-19 was reclassified into ‘Class 5’ (the same category as seasonal influenza) in Japan. Despite this, the Japanese government continues to promote vaccination. Many observers point out that the number of victims suffering from vaccine-related adverse effects actually far exceeds the number of deaths caused by the virus itself. Nevertheless, both central and local governments maintain implicit trust in pharmaceutical companies. Many politicians, scholars, and medical professionals are sounding the alarm regarding the dangers of the ‘Replicon’ vaccine (self-amplifying mRNA), which Japan was the first in the world to approve. A government entrusted with the lives of its citizens must exercise far greater caution. While most countries halted vaccinations after the third dose, Japan uniquely continues to administer seventh and eighth doses.
This suggests that the outcome is manifested in the 926,443 excess deaths shown below.

Why is it that an increase in sunspots leads to a rise in infectious disease outbreaks?
While visible light is largely independent of sunspot activity, an increase in sunspots significantly boosts high-energy radiation, including ultraviolet rays, X-rays, and gamma rays. These emissions are believed to affect the human autonomic nervous system and endocrine functions, thereby intensifying immune responses.
Further research in this area is expected to yield significant insights.
- The Relationship Between Solar Activity and Seismic Events
Solar activity is also linked to the occurrence of major earthquakes. Since the year 2000 in particular, there has been a frequent recurrence of massive earthquakes reaching magnitude 8 or higher.
On March 8, 2011, the international sunspot count reached 140; just three days later, the Great East Japan Earthquake occurred.
High-energy radiation emitted from sunspots heats the Earth’s core, which in turn accelerates mantle convection. This process influences the movement of tectonic plates, triggering massive earthquakes, tsunamis along plate boundaries, and intensifying volcanic activity. This mechanism is identical to the principle of heating water in a microwave oven, where the water begins to boil from the center outward.
Within the Ring of Fire, the region where mantle upwelling occurs is the East Pacific Rise, which runs north to south to the east of Hawaii. Whenever mantle activity intensifies, the Kilauea volcano on the Big Island of Hawaii invariably erupts; this, in turn, triggers a series of major earthquakes and volcanic eruptions throughout the Pacific Rim. The same logic applies to the correlation between volcanic eruptions in Iceland and seismic activity in subduction zones. Notably, just six days before the Great East Japan Earthquake mentioned in the diagram above, Kilauea had indeed begun to erupt.
Prior to the massive M8.8 Kamchatka earthquake on July 29, 2025 (UT), continuous eruptions were confirmed at the Kilauea volcano, accompanied by frequent volcanic activity across the Ring of Fire. It is evident that mantle activity is intensifying. Consequently, the occurrence of the Nankai Trough mega-earthquake is now considered only a matter of time. We must implement robust and thorough earthquake preparedness measures immediately.
Over the past 300 years, the mid-1900s—the period of the most intense solar activity—saw three consecutive Magnitude 9 earthquakes, followed by a frequent recurrence of massive quakes of M8.5 or higher. Since the Great East Japan Earthquake (M9.0) was the second such event following the Sumatra Earthquake (M9.1), there is a strong possibility that further M9-class earthquakes will continue to occur in the future.
- The Influence of Solar Activity and Lunar Tidal Forces on Earthquake Generation
Major earthquakes and volcanic eruptions frequently occur during the full moon or new moon. Similar to how the gravitational pull of the sun and the moon draws seawater to create spring tides, the Earth’s crust—which floats atop the mantle—is also pulled by these gravitational forces. This creates stress and deformation, triggering the release of energy accumulated along plate boundaries and active faults. Notably, both the Great Hanshin-Awaji Earthquake and the Sumatra Earthquake occurred during a full moon.

- Solar Activity and Climate Variability
The surge in high-energy radiation from the sun raises temperatures on the Earth’s surface and sea levels, intensifying the temperature gradient between equatorial and polar regions. This triggers shifts in air and ocean currents, leading to the development of powerful fronts and the intensification of typhoons and low-pressure systems. Furthermore, the meandering of the jet stream causes extreme temperature fluctuations in mid-latitudes, resulting in frequent floods, droughts, wildfires, and unseasonable cold spells. The anomalous weather patterns of recent years are a clear testament to this reality.
- Predicting Future Solar Activity
The Royal Observatory of Belgium has released its projections forfuture solar activity.
＜The Royal Observatory of Belgium＞
According to the chart, the peak of the current cycle is situated in 2024, though official forecasts suggest a timeframe near 2030.
In predicting future solar activity, it is crucial to note that while the peak sunspot numbers for the first solar cycle of each century were approximately 96 in the 1700s, 76 in the 1800s, and 105 in the 1900s, the figure for the 2000s has surged to approximately 173.
If solar activity follows the same pattern as the third, fourth, and fifth cycles of the 1900s, it is projected that the corresponding cycles of the 2000s could see peak sunspot numbers reaching between 300 and 340. This suggests we may be approaching a period of solar activity that far exceeds anything within our current imagination.
In any case, humanity must prepare itself for the profound impacts of solar activity—the likes of which we have never before experienced. The global climate change and abnormal weather patterns currently driven by global warming have reached a point of no return.
What kind of world-shaking upheavals will we face in the first half of the 21st century? From massive earthquakes, extreme weather, and rising sea levels to catastrophic disasters, wars, regional conflicts, pandemics, and the resulting poverty, famine, and refugee crises—the unfolding of these events depends entirely on future sunspot activity.
Now is the time for us to recognize just how intimately our lives are connected to the pulse of the sun.
Throughout the history of the East since ancient times, the Three-Legged Crow has consistently appeared as a potent symbol of the sun. In the modern era, advancements in science and technology allow us to observe the sun in meticulous detail, providing a vast array of real-time data and diverse imagery. In antiquity, however, the sun could only be perceived with the naked eye. What, then, is the significance of ancient people depicting a three-legged crow within the sun?
When ancient people saw a rabbit or a toad in the moon, they were likely exercising their imagination based on the patterns visible on the lunar surface. However, the discovery of the three-legged crow within the sun must have stemmed from witnessing bird-like shadows during the rising or setting sun. It is imagined that these shadows were, in fact, giant sunspots. Since sunspots almost always appear in clusters, ancient people likely associated them with crows—black birds that are known for constantly moving in flocks.
However, the crucial point is that there was once an era when sunspots could be clearly perceived with the naked eye, leaving a profound and lasting impression on the collective consciousness of the people. In other words, it signifies that there was an era when solar sunspot activity was exceptionally intense.
During that era, the intense solar activity likely triggered a variety of global upheavals. It is probable that people stood in awe of the sun, began to deify it, and that sun worship spread among the masses as a result. The prevalence of sun-worshipping faiths among ancient civilizations serves as a powerful testament to this reality.
When the three-legged crow is once again perceived upon the solar surface with the naked eye, might it not signal the dawn of a new era for humanity?
