Climate change prevents the Genghis Khan village from conquering the Southern Song

Central and many other regions in China warm up, causing food productivity to skyrocket, creating a solid foundation for the Song Dynasty to develop its economy and military, slowing the expansion of the Mongol Empire.

Climate change helps Nam Tong prevent the invading army of Genghis Khan

According to SCMP, central, eastern and southern China are among the hottest places in the 13th century in Asia. The climate is unusually warm, resulting in an increase in rice productivity, a surplus of food enough to feed the army and a solid foundation for local economic and technical development.

Therefore, this is evidence that climate change acts as a Great Wall in the south central region, preventing Mong troops from invading.The Nam Song house benefited most from climate change, while the Yuan dynasty was increasingly weakened by economic exhaustion and corruption.

The international team led by Shi Feng, professor of the Institute of Geology and Geophysics at the Chinese Academy of Sciences, together with European, Japanese, Nepali and Pakistani colleagues analyzed hundreds of data around the world, comparing summer temperature changes in Asia in the past millennium.

"Temperature has increased in central, eastern and southern China (in the 13th century), significantly higher than in other regions, comparable to the 20th century , " quoted a report published on November 5. The author's Climate Change magazine.

China's economy in the middle, east and south of that period was very developed, accounting for 60% of global GDP. That period also marked many important inventions, including gunpowder and compass.

The Mongol Empire was founded in 1206, surviving throughout the 13th century. Genghis Khan (1162-1227) dragged troops to conquer many countries around the world, as far as the west, including Poland and the year. 1259. However, the south expansion is much slower. Although many times pulled troops to capture the south, but it took up to four decades, the descendants of Genghis Khan conquered the Southern Song, unifying China in 1279.

Dong Guanghui, professor of geological history at Lanzhou University, who is not involved in the study, said that ancient society is much more sensitive to climate change, since the economy was mainly based on agriculture and trading activities related to agriculture. However, Professor Dong said, should not exaggerate the impact of climate change.

"There are many warming areas in history, however, there is only one Genghis Khan , " Dong said. " History is full of randomness. Climate change doesn't decide everything."
