The La Madre phenomenon has also become a decadal oscillation in the Pacific Ocean, with two lunar declination maximums and one lunar declination minimum periods forming the La Madre cold phase period, and strong tides lead to frequent disasters. Two lunar declination minima periods and one lunar declination maximum period form the La Madre warm phase period, and the decreasing tidal intensity leads to accelerated global warming.

The declination of the moon is about 18.6 years, a La Madre cycle is about 56 years, 1946-1976 is the La Madre cold phase, from 2000 the earth entered the La Madre cold phase again, although no specific data are available, the cold phase period of the 19th century was about 1889, 1834 and 1778 20-30 years later.

During the cold phase of La Madre, extremely strong earthquakes, severe low temperature frost damage, abnormal droughts and floods, strong winds and tsunamis, and influenza outbreaks occurred in an orderly manner in time and space, forming a disaster chain.

The statistical law shows that during the cold phase of La Madre, strong earthquakes, low temperatures, droughts, floods, hurricanes accompanied by La Niña, and influenza accompanied by El Niño will become more and more intense. The earthquake and tsunami in Indonesia at the end of 2004 and the freezing damage at the beginning of this year are nature's warnings to mankind: the disaster chain of the cold phase of Ramadre has been set in motion, and people must be prepared [10].

During the cold phase of La Madre, natural disasters are interconnected in a chain and stimulate each other, providing harbingers and signals for human beings to prevent and predict disasters

1. Earthquakes and volcanic disasters

"La Madre" is a high-air pressure current, also known as the Pacific Decadal Oscillation, which alternates over the Pacific Ocean in two forms: "warm phase" and "cold phase", respectively. When the "La Madre" phenomenon occurs in the form of a "warm phase", the water surface temperature near the North American continent rises abnormally, while the ocean surface temperature in the North Pacific Ocean decreases abnormally. At the same time, the Pacific high air flow moved from the two continents of the Americas and Asia to the central Pacific Ocean, and the low air flow was the opposite, raising the sea level in the central Pacific Ocean. When "La Madre" comes in the form of a "cold phase", the situation is completely reversed. Repeated rises and falls in the central Pacific Ocean cause a seesaw movement in the earth's crust, triggering strong seismic and volcanic activity.

Since 1889, there have been 22 earthquakes of magnitude 8.5 or greater. From 1889 to 1924, the cold phase of La Madre occurred 6 times, and from 1925 to 1945, the warm phase of La Madre occurred once. From 1946 to 1977, the cold phase of La Madre occurred 11 times, and from 1978 to 2003, the warm phase of La Madre occurred 0 times. In 2004-2008, the cold phase of La Madre has occurred four times. The law shows that the cold phase period of La Madre is the concentrated outbreak period and the low temperature period of global strong earthquakes. The year 2000 entered the period of La Madre cold phase, and the period from 2000 to 2035 is the period of global strong earthquakes.

The anomalous eruption of the Icelandic volcano in 2010 was noteworthy.

2. Typhoon and hurricane disasters

Since 2007, the number of typhoons that have landed in China has increased, and the time and place are relatively concentrated, resulting in large losses, and some areas have been repeatedly affected by disasters, causing serious losses. There has been a sharp increase in the number of typhoons making landfall in China during the cold phase of La Madre.

There is a cyclical pattern in the occurrence of hurricanes in the data records of the last 60 years. According to Science magazine, the last period of high hurricane activity was from 1926 to 1970, and it hit the East Coast and the Caribbean hard. From 1970 to 1994, the hurricane turned into a period of low activity. In 1995, a new period of high hurricane activity began.

From this, we can see an obvious pattern: from the warm phase of La Madre to the cold phase, the hurricane is in the period of high activity, from the cold phase of La Madre to the warm phase, the hurricane is transferred to the low active phase, and the hurricane is generated by the high temperature of the ocean surface, which eventually leads to the overturning of the cold water in the deep sea and the cooling of the ocean surface, and its physical mechanism is also obvious. The period from 1995 to 2030 was when La Madre moved from the warm phase to the cold phase, and hurricane activity re-entered the period of high activity.

3. Low temperature

The low temperature period at the beginning of the 20th century, the warming in the 30s and 40s, the low temperature in the 50s and 60s, and the rapid warming after the 80s correspond to the transition of the cold and warm phases in La Madre. The end of 18 consecutive years of warm winter in our country was a natural consequence of the cold phase of La Madre in 2000 and the earthquake and tsunami of 26 December 2004 in Indonesia.

There is a good correspondence between the frequent occurrence of strong earthquakes and low-temperature frost damage, and Guo Zengjian's "deep-sea earthquake cooling theory" is a reasonable explanation: the giant earthquake in the ocean and its surrounding areas produces a tsunami, which can make the cold water in the depths of the ocean move to the sea surface, so that the water surface is cooled, and the cold water absorbs more carbon dioxide, so that the earth can be cooled for nearly 20 years. The increase in temperature after the 80s of the 20th century is related to the increase in carbon dioxide emissions due to human activities, and there were no major earthquakes during this period. Hurricanes are caused by high temperatures on the ocean surface, which eventually lead to the cold water of the deep sea and the cooling of the ocean surface, and the physical mechanism of cooling is also obvious. With the intensification of earthquakes and hurricanes in the cold phase of La Madre, global temperatures will gradually cool in the next 20 years.

Historical records show that during the "cold phase" of La Madre, El Niño years (La Niña years) are prone to severe cold injury. (1954-1955), 1957, (1964), 1969, 1972, 1976, and 1977 severe low temperature chilling injuries occurred in China during the "cold phase" of "La Madre" from 1947 to 1976.

Since today's climate trends are very similar to those of the Dalton minimum, it is necessary to focus on the severe natural disasters that occurred in China after 1790.

China was in the Jiaqing (1796-1821) and Daoguang (1821-1850) periods, and we know that Jiaqing was the turning point of the Qing Dynasty from prosperity to decline, which perfectly conformed to the climate change cycle. In the Jiaqing Dynasty, the uprisings of the people of Hunan and Guizhou, the uprisings of the Yao people in Hunan, Guangdong, and Guangxi, the uprisings of the White Lotus Sect in Sichuan, Chu, and Shaanxi, and the peasant uprisings in Henan, Hebei, and Shandong shook the foundation of the Qing Dynasty's rule.

Although there are corrupt officials and corrupt officials, it has always been believed that the people risked killing their heads to rise up, and the pressure of survival is the first element.

In the Daoguang period, we remember most clearly that the Daoguang famine, several provinces starved people, from the Qing history can be clearly summarized, in the period of 1800-1900, the Qing Dynasty's natural disasters far exceeded the previous dynasties and the Qing Dynasty's Qianlong period, in which floods and droughts occurred one after another, eventually leading to the demise of the Qing Dynasty.

The specific numbers are too complicated, and a search on the Internet shows that the floods, droughts, and locust plagues in the Daoguang period of the Qing Dynasty have reached their peaks.

--------------------------------------------------------------------

The year 1816 was the last time the sunspots were minimally extended, also in the cold phase of La Madre, marked by the eruption of Mount Tambora on the Indonesian island of Sumbawa in 1815.

The widespread crop failures of 1816 led to "food riots" in almost every country in Europe, fueling the revolutionary passions that swept across the continent. In the United States, hungry people moved westward, changing the structure of agriculture and expanding their territory. In China, famine led to popular revolt, triggering the Qing Dynasty's decline from prosperity to decline. At the same time, the haze of nature also affected the style of painting and the tone of literature, and promoted the birth of new religions and the emergence of new inventions. A global climate change that affects the direction of the whole world. Natural historians, on the other hand, attribute this cascade of changes in part to a volcanic eruption in Indonesia. A hundred years later, experts are beginning to worry about whether the eruption of a volcano in Iceland will bring the planet back to cold.

In 1816, global low temperatures hit Europe, the Americas and even China, and it is conservatively estimated that the average temperature in the Northern Hemisphere dropped by 0.4-0.7 in 1816. In the West, this year is known as the "Year of No Summer", and in folk memory it is known as "1816 of the Frozen to Death". The famine in Yunnan during the Jiaqing period shared a common climatic background with what the West calls the "Year Without Summer".

The low summer of 1816 caused the collapse of nature, but what are the causes of the extreme weather? It is generally considered that the solar magnetic field activity of this year is very inactive, in scientific terms, in Dalton minimum. This period of magnetic inactivity lasted from 1795 to 1820. Prior to this, the Mondstadt Minima caused 70 years of continuous low temperatures in the Northern Hemisphere.

The so-called Mondstadt Minimum refers to the period from 1645 to 1715 when sunspots decreased significantly. This conclusion was discovered and proposed by the British astronomer Mondstadt. At its lowest in Mondstadt, the weather in Europe is much colder than usual, and Londoners can host a variety of events on the frozen Thames River in winter. The Mondstadt Minimum was sandwiched between the colder Xiaoice Age, known as the Xiaoice Period from 1450 to 1850. During this period, glaciers expanded in many parts of Europe, warm summers disappeared, and rivers, ports, and canals froze. The second factor is that the Sun deviates from its position in the solar system during the Dalton minimum, which occurs every 178-180 years. But the more immediate cause of the cold phenomenon in 1816 was the eruption of Mount Tambora in 1815.

On April 5, 1815, the magma of Tambora volcano on the Indonesian island of Sumbawa, which had been dormant for 5,000 years, erupted violently. Five days later, at around 7 p.m. on April 10, 1815, the Tambora volcanic rock erupted again, and then continued intermittently for more than 100 days. It was the largest eruption of Mount Tambora in nearly two centuries and the deadliest recorded volcanic disaster in history, with a total of 117,000 deaths.

By the time the smoke cleared, Mount Tambora had "ejected off the summit", plummeting from 4,100 metres to 2,850 metres in height. Mount Tambora erupted 10 times more violently than the 1883 Krakatoa eruption, spewing ash into a layer in the Earth's atmosphere, which "covered the sky with one hand", blocking out the light and heat released by the sun to the entire earth, resulting in cold weather.

Because volcanic ash takes time to move through the atmosphere, it did not immediately affect the climate of the surrounding area until 1816. This was preceded by two other eruptions, in the Caribbean in 1812 and in the Philippines in 1814, and the ash that had already existed in the atmosphere was exacerbated by the eruption of Mount Tambora.

Diaries and newspapers in Europe and the United States at the time recorded the weather in 1816 in detail, such as unusual colors in the sky, huge sunspots, and other strange phenomena. These sources corroborate the research of today's natural historians: changes in the sun's magnetic field, huge volcanic eruptions, and sunspot activity caused famine, drought, and devastating rain and snow in the Northern Hemisphere. The tidal maximum in 1770 was also an important factor.
