Bet365 lotto review September 28，The official website of the University of Cambridge will publish a message，A research team led by the researcher at the school，In the past two thousand years，The importance of volcanic in natural changes may exceed people's past cognition，volcanic activities have profoundly affected the direction of human economy and society。Related papers "The Outstanding Restrictions of Volcano on Climate Change and Human History in the post -AD" recently published on the international journal "Tree Age School"。

By analyzing more than 9,000 trees samples，Researchers have obtained precise records that can be traced back to the summer temperature in North America and Eurasia, which can be traced back to the 1st AD。Researchers compare these data with the records of large volcanic eruptions and major historical events in the history of human development，The period of determining the warming and coldness of climate。Research on the ice nucleus，Researchers have confirmed the impact of volcanic eruption on temperature changes。From bet365 best casino games a certain extent，The volcanic ash produced by volcanic eruption blocks the direct irradiation of the sun on the surface，As a result, lower temperature and shorter crop growth season have caused some regions。and the 3rd century with a small number of volcanic bursts、10th and 11th centuries，The earth's climate is relatively warm。

Professor Ulf Büntgen, a professor at the Department of Geography of Cambridge University, said，This study allows people to clearly understand the difference between natural climate change and human climate change，to better understand the natural reasons and social consequences of climate change over the past two thousand years。

bet365 live casino games Researchers discovered，In the ancient Rome period and the Middle Ages, there were no frequent large -scale volcanic eruptions，The earth in these two periods has maintained a relatively sustainable warm climate。At the same time，China and Europe have presented the situation of social prosperity and political stability。In the period when volcanic activities are relatively frequent，Human society usually also increases conflict in history、The stage of economic recession。Bangtegen Represents，People should further study the question of how climate change has affected the process of human civilization in history。This has an Bet365 app download important reference significance for us to deal with climate issues in the future。
