n fact, the climate has changed in cycles throughout history. According to scientific data, severe climate changes that occur every 40 million years and last for 1 to 1.5 million years have made life on earth impossible, seas have become deserts, deserts have become seas, and many living species have disappeared from the face of the earth. These frequent climate changes caused ice ages on Earth. During these periods, many macroorganisms were completely wiped out from the earth. Less intense changes, which occur every 40-50 thousand years and last for 500 to 1000 years, within these cycles, caused the displacement of living things on the earth and changes in the ecosystems in which they lived. During this period, the continents separated or moved further apart, and some creatures specialized to certain continents or regions. There has been a huge decrease in the number of living things. More limited and less severe climate changes that occurred every 6-7 thousand years and lasted for 5-10 years during these two cycles severely reduced the population of some species in certain regions. It caused great damage to the food chain and caused periods of famine, especially for people.
These climate changes generally damaged the biological cycle on earth, as well as repaired the abiotic cycle of nature. In other words, it served as a repair mechanism for the earth by regulating the water, carbon and nitrogen balance and minerals, heat and gas transfer that were disrupted in the world as a result of climate changes and living things. It rearranged the distribution of natural resources, especially with the deterioration of inter- and intra-species competition. As a result of these changes, the earth lost some species but became richer in terms of biological and ecological diversity. Now the impact of a new climate change is being felt intensely on the earth. We are in a period when the human species is the most populous in terms of population and the most influential in terms of impact on the earth. This period in which we are experiencing a new wave of climate change seems to have coincided with one of the rings in the normal flow or transformation of the earth, and it seems to have been intensified and accelerated by the influence of human beings. The average temperature of the earth in the last 2 centuries has increased by 1°C, and the surface temperature of the earth has increased from 14°C to 15°C in 150 years. The increase in extreme weather events and their intensity, which have increased almost 300 times in the last 50 years, reveals this change all over the world. In short, we are talking about a very imminent threat that will affect every moment of life.
