Scientists have identified the cause of climate warming in the Arctic and Antarctic

According to the entrenched view, global warming is due to human activities. Moreover, the dominant version is called the carbon footprint of the industry. However, Russian scientists from a large group of scientific organizations have identified another cause of climate change in the Arctic and Antarctic, which began at the end of the XNUMXth century.

The Ministry of Education and Science of Russia told RIA Newsthat the anthropogenic concept of global warming looks doubtful and there is an alternative version - the seismogenic-trigger hypothesis, i.e., consisting of natural factors that do not depend on human activity. According to experts, it was catastrophic earthquakes that gave a sharp start to warming in the Arctic in the late 1970s. The growth of industrial production in this period was not observed, so the anthropogenic concept does not fit into this process.



Experts have established a connection between strong earthquakes on the Arctic shelf and the beginning of warming. Moreover, the correlation manifested itself with a time shift of 20 years. Earthquakes occurred in the interval 1957-1965. For two decades, deformation tectonic waves have covered a distance of about 2 thousand km between the Aleutian arc and the Arctic shelf, moving at a speed of about 100 km per year. It was these waves that led to the destruction of metastable gas hydrates located in the frozen rocks of the Arctic shelf - natural "reservoirs" of methane, from which the gas entered the atmosphere, contributing to a noticeable change in the Arctic climate.

The same seismogenic-trigger mechanism was also observed in the Antarctic, where the onset of the phase of anomalous climate warming occurred almost simultaneously with the Arctic. In 1960, in the central part of the Chilean zone, in relative proximity to Antarctica, the most powerful earthquake with a magnitude of 9,5 occurred in the entire history of observations. An increase in temperature in Antarctica began to be recorded against the background of a sharp intensification of the destruction of ice shelves.

The geodynamic model compiled by experts predicts further acceleration of the destruction of glaciers and climate warming in Antarctica in the near future. This is due to the unprecedented increase in the frequency of the strongest earthquakes in the South Pacific in the late XNUMXth and early XNUMXst centuries.

The project manager, Academician of the Russian Academy of Sciences Leopold Lobkovsky, believes that in this regard, it is necessary to revise economic и political solutions that provide for the rapid reduction of industries. According to him, the decrease in industrial production may adversely affect the development of the economies of entire regions of the planet, in particular Russia, China, the Middle East and others. Therefore, it is important to approach such decisions carefully, carefully weighing the consequences.
