Solar-Climate Theory Sheds New Light On History Of Chinese Civilization

great wall of chinaScientists say they have found evidence beneath a lake in northeastern China that ties climate change and 500-year sun cycles to ups and downs in the 8,000 years of Chinese civilization.

According to the study by a team at the Institute of Geology and Geophysics in Beijing published in the science journal Nature Communications this month, whenever the climate warmed, Chinese civilization prospered and when it cooled, it declined.

While historians have used various social and economic factors to explain changes over the millennia, Dr. Xu Deke, lead author of the paper, and his colleagues said that while people played their part, their study indicated that cycles in solar activity influenced human activity.

“We just point out there is a natural constraint on human efforts,” Xu said.

Previous research linking Chinese history to climate relied on written records, but ancient texts contained only subjective descriptions of the weather and social development. The records also go back only so far – writing in China was not invented until 3,600 years ago.

For this latest study, the team and its leader, Chinese Academy of Sciences professor Lu Houyuan, took plant and lake bed sediment samples to track climate change over the centuries and compared them with written records.

They visited Lake Xiaolongwan in the Changbai Mountains in Jilin province and studied the spread of plant life such as oak trees to map the transitions between warm and cold climate phases in northern China.

By comparing the records and their research, the scientists found that the warmer the climate, the more prosperous the civilization in terms of grain cultivation, animal domestication and human settlement.

Over the decades, researchers have established more than 4,000 carbon dating databases for archaeological finds in northern China.

From these, the team obtained a benchmark for the intensity of human activity in different periods. Their study also found that 500-year cycles often ended with rapid climate cooling.

Whenever that happened, societies started to collapse and neither culture nor political systems could sustain them. This, Xu said, was a lesson for modern China.

“The most effective countermeasure is science and technology,” he said. “We are in a much more capable position than our ancestors with the help of technology and machines in the face of global cooling, but preparation must start now.”

Citing this and earlier studies, Xu said that over the next few decades the Earth would enter 25 years of cooling, although greenhouse gases could slow the temperature drop.

Cooling would increase the size of polar ice caps and lower sea levels. Areas such as southern China could benefit as land would be reclaimed from the sea.

But overall, a cooling climate would continue to have a more negative effect on civilization than warming, Xu said.

Dr. Liu Yonggang, a Peking University scientist who studies ancient climate, said the researchers had provided important new information and perspectives.

Human societies have gone through temperature cycles such as the Medieval Warm Period (900- 1300) and Little Ice Age (1300-1870) Liu said, but most of that data came from Europe, not China.

The study left one big question. “Why do the sun’s activities vary every 500 years? Nobody can explain,” he said.

“We need to know more about the inner working mechanism of the sun, otherwise the future remains unpredictable.”

    The main serious producers of CO2 are:
    1. Oceans
    2: Volcanoes
    3. Forests
    (4. Man is irrelevant.)
    Therefore if we want to dramatically reduce or eliminate CO2 emissions the best choice we have are:
    1. Cover up all oceans with a plastic foil
    2. Plug all volcanoes
    3. Cut down all the trees of all forests in the world.
    Obviously this is not possible, so the “Gretins” want to make the antropo-centric emissions (0.00000….%) pay for something that depends on solar activity 99.9999…%. Of course, we’re also talking about BILLIONS of public money spent every year and hundred- thousands so-called “scientists” that make a living on this gigantic hoax.

    Never understood what the pretend greenies have against a greening planet .
    I suppose it conflicts with their population culling plans .
    There is a reason Amazon or nearly anyone else , don’t have head offices in Antarctica .
    If CO2 was such an imminent danger why haven’t they band green houses ?
    Oh because a 200% increase is plant food on steroids .
    Ban green houses and half of California agriculture shuts down .
    Hmm that could be an election Epstein .

    I think it is a remarkable position to claim
    that increased solar activity warms the earth
    and that decreased solar activity
    cools the earth.

      It’s true

    So global warming/cooling is all about the sun. Go figure. Wonder if the computer models take into account that giant bright orb in the sky? Maybe the global warming pagans should be worshiping the sun instead of worshiping Gaia.
