18 16, why is there no summer this year and the climate in In the snow has changed a lot?

18 16 There was no summer this year. In July, due to the eruption of Mount Tambora, gas covered the sun, which led to global cooling, and the snow climate changed greatly.

No summer year is 18 16, which is the 21st year of Qing Jiaqing in China. According to historical records, in June and July this year, extreme weather occurred in southern China, such as Jiangxi and Anhui. In July and August, there was heavy snow in the Yangtze River basin. In June, the temperature in Pengze, Jiangxi Province plummeted and snow appeared on the mountain. In July, heavy snow fell suddenly in parts of Anhui, and the snow on the ground was more than one inch thick. Due to the sudden drop in temperature, people in the Yangtze River basin actually began to keep warm in June and July, which is a rare spectacle in the Millennium.

Due to the sudden drop in temperature, the growth of crops in the field was seriously affected, which led to a large reduction in grain production at that time, which in turn triggered a food crisis. Because of this extreme weather that lasted for nearly three years, people began to eat bark without food. In the end, even the bark was gone, so we had to eat Guanyin soil to satisfy our hunger. Many people lost their lives in this natural disaster. According to historical records, the famine in Yunnan is the most serious: is it a great famine and the road is dead? .

In the same period, a similar situation occurred in the whole northern hemisphere except China. It snows in Britain in July and winter in Germany in August. Plants and trees were frozen, rivers froze and crops froze to death. About 200,000 people in Europe died from this sudden natural disaster. Due to the summer of 18 16, the temperature plummeted and it snowed in July. Europe called this year? A year without summer? .

Mount Tambora erupted. What do we often say? Snow in June? There must be resentment. Is it because you are angry this year? Obviously not, all this is caused by the butterfly effect caused by the eruption of Mount Tambora.

Tambora volcano is an active volcano, located in Sumbawa Island in northern Indonesia. It broke out in 18 15 and lasted from April 5 to mid-July of that year. This is the largest volcanic eruption ever recorded in the world, and the volcanic explosivity index (VEI) is 7. The loud noise of volcanic eruption can be heard 2500 kilometers away. Volcanic eruption spewed out14 billion tons of magma, releasing energy equivalent to 50,000 times the explosive power of the atomic bomb dropped by the United States in Hiroshima, Japan at the end of World War II, resulting in the death of about 7 1000 people.

Butterfly effect The eruption of Mount Tambora triggered the butterfly effect. Volcanic ash and some gases from Mount Tambora surround the earth, including carbon dioxide, water vapor, sulfur dioxide, methane and other gases. When these gases pass through the atmosphere, they react and become sol, which blocks and reflects sunlight, so the earth loses the heat of the sun, and the temperature drops, which eventually leads to a global temperature drop of 0.53 degrees. Its influence suddenly appeared in the world in the following year 18 16, and a rare weather anomaly appeared in the northern hemisphere. A year without summer? .

Who would have thought that a volcanic eruption thousands of miles away would affect global climate change so seriously? The butterfly effect is really amazing. This also proves once again from one side that the earth is the same fate, and it is everyone's responsibility to protect it, otherwise, once something goes wrong, no one will be spared. Especially in recent years, the problem of global warming deserves our vigilance. Protecting the earth starts with you and me!
