According to a Rutgers co-authored study, volcanic eruptions have contributed to the collapse of the Chinese dynasty over the last 2,000 years by temporarily cooling the climate and affecting agriculture.


Large-scale eruptions create clouds that block sunlight for a year or two. It reduces warming of Asian lands in summer, weakens the monsoon, reduces rainfall, Crop harvest..

“We have for the first time confirmed that the collapse of the Chinese dynasty over the last 2,000 years is more likely to occur in the next few years. volcanic eruptionCo-author Alan Robock, a prominent professor of environmental science at Rutgers University, New Brunswick, said: Easy to collapse. The impact of cold climates on crops also increases the likelihood of conflict and further increases the likelihood of collapse. “

According to a journal study, scientists have reconstructed 156 explosive volcanic eruptions from 1 to 1915 AD by examining elevated sulfate cores in Greenland and the Antarctic ice core. bottom. Communication Earth and environment. Scientists also analyzed Chinese historical documents about the 68 dynasties and investigated the war in China from 850 to 1911.

Erupting volcanoes produce millions of tonnes of sulfur dioxide Upper atmosphere, Reflects sunlight and forms a huge sulfuric acid cloud that lowers the earth Average surface temperature..

Research states that large-scale eruptions can lead to “a dual crisis of significant cold and dryness during agricultural growth.”Impacts can be exacerbated and accelerated by livestock mortality Land deterioration And more crop damage from agricultural pests that survive during the milder winters.

Scientists have discovered that the “impact” of a small volcano on climate can disrupt the dynasty when political and socio-economic stress is already high. Larger impacts can lead to collapse without substantial existing stress. Other factors include lack of leadership, administrative corruption, and demographic pressure.

The influential Chinese concept of “mandate” has allowed some continuity between dynasties. By seizing power, the elite and the “common people” more easily embraced the new dynasty, which demonstrated God’s mission to rule the former. dynasty I was lost.

Scientist findings emphasize the need for preparation Future eruption, Especially economically Vulnerable population There is a history of resource mismanagement, such as Syria before the 2011 uprising, which may have been partially caused by the Ming and / or droughts (probably comparable to the Ming and Tang dynasties of China).

Eruptions in the 20th and 21st centuries were smaller than those during the Chinese Empire. Nonetheless, moderate eruptions could have contributed to the Sahel drought in the 1970s and 1990s, killing about 250,000 people and creating 10 million refugees in this economically marginalized area. Future large-scale eruptions combined with climate change are likely to have serious implications for some of the most populous and marginalized regions of the planet, studies say.


Monsoon rainfall response to volcanic eruptions depends on pre-eruption ENSO conditions
