The article provides information about climate changes, which have become one of the global problems, and their impact on the living world, which worries the world community more and more. Unstable weather conditions are felt not only in Azerbaijan but also in several countries of the world and create problems. Increasing attention to these problems is manifested in the holding of a number of international events, including scientific and practical conferences. According to the latest assessment report of the Intergovernmental Panel on Climate Change, the average temperature on Earth has increased by 0.8 degrees in the last 100 years. The increase in temperature is mainly due to anthropogenic factors. The basis of anthropogenic factors are gases that create a thermal effect: carbon, methane, nitrogen oxide, nitrogen 1 oxide and chlorine-fluorine compounds. Space observations of the last 100 years show that the intensity and frequency of storms and blizzards have increased. Hot winds, hurricanes, and precipitation have intensified. At the same time, the number of flood events has also increased. If the surface of the ocean used to heat up to a depth of 1000 meters, then the warming reaches up to a depth of 2000 meters; resulting in hot currents becoming even hotter. That is, the main factor in the increase of all these natural disasters is climate change.
