Recently, climatologists and other scientists have been aggressively wailing to the public and politicians with a request to pay close attention to the problem of the "greenhouse effect".
Official science believes that the “global” global warming is caused by increased man-caused human activity, an increase in the amount of carbon dioxide in the planet’s atmosphere in the form of exhaust gases from transport and industrial emissions. But is it really so?
Atmosphere of greenhouse gases
According to geological studies, before the beginning of the industrial era in the history of mankind, the content of carbon dioxide in the Earth’s air ocean was about 0.027%. Now this figure ranges from 0.03-0.04%. About 50 million years ago, its level was 1-3%, and then plant and animal life flourished in violent forms and an abundance of species.
The benefits of the greenhouse effect
Nowadays, this effect is used by agronomists in the cultivation of cultivated plants - it is enough to create a carbon dioxide concentration of about 1% in the air of the greenhouse, as the active growth of plants begins and their productivity increases. The low level of this chemical compound in the atmosphere (less than 0.015%), on the contrary, is harmful to the flora and inhibits the development of plants. There is also evidence that orange groves in California bore fruit 150 years ago much better than they do now. And this was due to a temporary increase in carbon dioxide in the air.
Is the greenhouse effect dangerous for humans?
As for humans, the upper limit of carbon dioxide in the air, hazardous to health, is more than 5-8%. It turns out that even doubling the current amount of this gas will not be noticeable to animals, and plants will begin to develop better. According to some estimates, the increase in the amount of "greenhouse" gases as a result of man-made activities of humanity is about 0.002% per year. At the current growth rate of the greenhouse gas content, it will take at least 195 years to achieve its doubling.
According to climatologists who advocate the “greenhouse effect” theory, an increase in carbon dioxide from 0.028 to 0.039% over the past 150 years has led to an increase in average annual temperature of about 0.8 degrees.
Periods of warming and cooling on Earth
In the history of the Earth there have been many periods of warming and cooling, not associated with a change in carbon dioxide in the atmosphere. In the period from 1000 to 1200 AD, there was a warming, in England they cultivated grapes and made wine. Then the small “ice age” began, when a decrease in temperature followed and the complete freezing of the Thames became a frequent occurrence. From the end of the 17th century, the temperature began to rise slowly, although in 1940–1970 there was a “rollback” towards lowering the average temperature, which caused panic in the society of the “ice age”. Temperature fluctuations within 0.6–0.9 degrees can be considered normal. The existence of a small “ice age” and other “uncomfortable” facts are being hushed up among the circles of climatologists.
Greenhouse gas levels
Studies of ice cores, whose age is several thousand years, showed that the level of carbon dioxide fluctuated both in the direction of increase and decrease. Moreover, these changes were more a result, not a cause of warming. Geological field developments in ice layers confirm this causal relationship.
Greenhouse gases
Greenhouse gases make up about 3% of the Earth’s atmosphere by volume. Of this amount, 97% is water vapor and clouds, and the rest is gases, such as carbon dioxide, methane, ozone and nitric oxide. Some researchers believe that water vapor and clouds are responsible for the occurrence of the "greenhouse effect" by 75% compared with other factors. Thus, a 3% change in the amount of water vapor in the atmosphere will have the same effect as a 100% increase in carbon dioxide from the initial amount.
The climate of the Earth has always changed. Our current “global warming” is not at all unusual by the standards of geological history. There are no justified facts proving the relationship of temperature changes with the presence of an increased or decreased amount of carbon dioxide in the air shell of the planet.
A number of factors influence the temperature change, and carbon dioxide is not dominant among them. Probably, ocean currents, continental drift of continents, vigorous activity of large volcanoes, changes in the parameters of the Earth’s orbit (ellipticity, axis orientation, etc.) have the greatest significance on the planet’s climate change.e.), the influence of asteroids and comets, solar radiation, magnetic storms and other effects from space.
