There is a strong suspicion that climate change occurs under the influence of carbon dioxide. According to the data of the last century it is 26 times smaller in the atmosphere than the water vapor. Surely it is water in molecular form and at high altitudes. A significant role in weather and climate is played by low-lying clouds - water in the form of drops. These clouds and clouds cover the influx of solar radiation. There is no direct link between the increase in CO2 and natural disasters. And it’s very content in the atmosphere is not only dependent on the combustion of fuel, but also on the state of the surface layer of the planet and the hydrological cycle. It is necessary to seek and eliminate the causes, the sources of its appearance. And it is even more accurate to look for the causes of climate change itself.
