這些德國呀、美國呀學者，真是不思進取，中國朝代輪替，怎麼可能與天氣改變有關呢？？！！！

絕對不是，肯定不是，一定與中國人自己有關－－－某顔色群體慣用說法

Epic drought broke the Ming dynasty: study

Posted Fri Apr 23, 2010 6:38am AEST

A study of tree rings has provided the most detailed record yet of at least four epic droughts that hit Asia over the past millennium, including one that helped end China's Ming Dynasty in 1644.

Data collected over the past 15 years for the study is expected to help scientists understand how climate change can unleash large-scale weather disruptions.

Any drastic shifts to the seasonal monsoon rains in Asia, which help feed nearly half the world's population, could have serious socio-economic consequences, according to scientists at Columbia University's Lamont-Doherty Earth Observatory.

Climate Shift May Have Helped Destroy Tang Dynasty

Over the past 15,000 years, there had been three periods in which the winter monsoon was strong but the summer monsoon was weak. The first two periods occurred at key moments during the last Ice Age, while the last ran from around 700 to 900. Each of these monsoon shifts coincided with what was, relative to the climate epoch, unusually cold weather.

The Tang dynasty, seen by many historians as a glittering peak in China's history, was brought to its knees by shifts in the monsoon cycle, according to a study published on Thursday. Famed for a flowering of art and literature and for prosperity brought by trade with India and the Middle East, the dynasty spanned nearly three centuries, from AD 618 to 907, before it was overwhelmed by revolt.
Scientists led by Gerald Haug of the Geoforschungszentrum (GFZ) in Potsdam, eastern Germany, looked at sedimentary cores taken from a lake at Zhanjiang in coastal southeastern China, opposite the tropical island of Hainan.

The magnetic properties and content of titanium in these deposits are an indicator of the strength of the winter cycle in the East Asian monsoon system, they believe.

They found that over the past 15,000 years, there had been three periods in which the winter monsoon was strong but the summer monsoon was weak. The first two periods occurred at key moments during the last Ice Age, while the last ran from around 700 to 900. Each of these monsoon shifts coincided with what was, relative to the climate epoch, unusually cold weather.

The twilight of the Tang began in 751, when the imperial army was defeated by Arabs.

But what eventually destroyed the dynasty were prolonged droughts and poor summer rains, which caused crop failure and stoked peasants' uprisings. Eventually, these rebellions led to the collapse of the dynasty in 907.

Haug's team suggests this shift in tropical precipitation occurred on both sides of the Pacific, not just in coastal East Asia.

連瑪雅文明摧毀，都說成與天氣有關，實在過份
Climate change destroyed Mayan Civilization and Tang Dynasty

That's the conclusion of recent research--that China's Tang Dynasty and the Mayan civilization. According to an article in The Australian,

There has never been a satisfactory explanation for the fall of the Tang emperors, whose era is viewed as a high point of Chinese civilisation, while the disappearance of the Maya world perplexes scholars.

Now a team of scientists has found evidence a shift in monsoons led to drought and famine in the final century of Tang power. The weather pattern may also have spelt doom for the Maya in faraway Mexico at about the same time, they say.
Both ruling hierarchies at the start of the 10th century were victims of poor rainfall and starvation among their peoples when the harvests failed.
