Christensen C.S. Laser technology change knowledge about the Mayan Empire: the major decline of the Mayan culture around the years 800-1,000

The Maya Empire which includes areas that we now know as southern Mexico, western Belize and Guatemala peaked on its development with population of up to 16 million. That’s far more than previously thought. It was formerly believed that the Maya culture peaked with a population of around 7 to 11 million people spread across the territory 95,000 square km. The latest research builds on the 2018 analysis and has resulted in a 45% jump in the new population estimates of Maya civilization. The new estimates now range from 9,5 million to 16 million people in the late period from the year 600 to 900. In this article the author analyse the reasons why the Mayan culture experienced a breakdown more than 1,000 years ago. These reasons are established in the context with the influence of climate on the course of history and the vulnerability of mankind in the in the terms of transformations caused by climate change.

Christensen C.S. Anthropogenic climate change, climate disasters and the role of nature: with special focus on the year 536

Earth’s climate has changed throughout history. Just in the last 800,000 years there have been eight cycles of ice ages and warmer periods, with the end of the last ice age about 11,700 years ago marking the beginning of the modern climate era and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives. The current warming trend is different because it is clearly the result of human activities since the mid-1800s, and is proceeding at a rate not seen over recent millennia. It is undeniable that human activities have produced abundance of gases in the atmosphere that have trapped more of the Sun’s energy in the Earth system. This extra energy has earned the ocean and lands, which lead to widespread and rapid changes in the environment. In this paper there are analysed anthropogenic changes, nature’s own role and climate disasters in comparing the results obtained into perspective with incidents in the year 536.
