Duration of Climate Cycles during the Last Millions of Years and Hundreds of Thousands of Years and Modern Climate Anomalies

Abstract

The problem of the end of the modern interglacial is discussed. Following theoretical predictions, cooling should soon begin after the end of the modern interglacial and Quaternary climate period. However, as climatologists note, now weather anomalies have begun to occur more often: high and low temperatures, heavy rainfall, thunderstorms, hurricanes, and floods are breaking long-term records. Unfortunately, the scientific community has not reached a consensus regarding the causes of climate change during this period. Global numerical models of Earth’s climate system have discrepancies with observed climate changes. Supporters of anthropogenic global warming, in spite of everything, ignore the natural factors of climate change, such as tectonic waves, glacial destruction, and the ocean, which actively participates in the exchange of gases with the atmosphere, volcanic activity, earthquakes, etc. Data on changes in the global temperature of Earth’s surface on a time scale of the last 700 million years and ~70 million years are analyzed and periods of warming and cooling were identified. The cyclicality of climate changes in the Quaternary (the last approximately 2.5 million years) is analyzed as one of the most important features of the climate system, used to assess both changes in individual environmental components in the past and to predict climate change in the future.
