Cyclical changes in terrestrial elements and their combined effect cause climate oscillations, during which periods of glaciation and warming (glacial and interglacial periods) alternate on Earth, but even these are not stable climates, but consist of a series of colder and warmer phases. The most recent interglacial stage (Riss-Würm) lasted for about 15,000 years (130–115,000 years ago), during which the Earth’s climate was warmer than it is today. This was followed by another glacial period, which included one of the coldest phases of the Ice Age. Since our interglacial period (the Flandrian) began approximately 12,000 years ago, it could be concluded that in a few thousand years, our planet’s climate will begin to cool again and another glaciation will occur. Interestingly, because of this, researchers did not realize for some time that we were facing warming rather than cooling, as the climate gradually cooled between 1940 and 1970. It later turned out that this cooling was caused by sunspots, meaning that less solar radiation reached the Earth than before. At that time, it was widely believed that a new ice age was coming. However, since 1980, the Earth’s climate has been warming almost continuously: here we must mention another significant factor affecting our climate, namely the amount of greenhouse gases in the atmosphere.
