What causes global warming?

Global warming concerns the increase in the temperature of the Earth, which is expected to be partly caused by a greenhouse effect or excessive release of gases such as carbon dioxide, methane and nitrous oxides, as well as ozone layer depletion that is released into the atmosphere.

Many people believe that global warming is largely due to the impact of human activities, especially industry and agriculture. However, although human activity is very likely to contribute a large factor, we are not the only cause of global warming. In addition, the problem of growing global temperatures is not an exact science.

Scientists believe that over the last 400,000 years there have been four almost identical weather cycles, each with a little over 100,000 years. It was almost 100,000 years cold during each cycle. Then there was a much warmer period lasting 10 to 20 thousand years of shower temperature comparable to the present. By studying weather patterns in terms of 10,000 years, it is likely that temperature fluctuationsIn the year and a gradual increase in the average global temperature indicates the natural cycle of "global warming".

In the last few thousand years, the main cause of climate change has been caused by the cyclic variant of the Earth's orbit around the Sun, which changed the average amount of energy received by the Earth from the Sun. These variations in the Earth's orbit have created several very long “astronomical seasons”, similar to the “regular seasons”. They were the main cause of climate change and created a number of ice ages and "warm" periods, such as the ones we are now experiencing.

This natural astronomical cycle has a domino effect on the planet, which further increases the incident Global warming. One very important factor includes the Arctic regions. A slight increase in temperatures is enough to start melting the permafrost of the Earth, a country that has been frozen since the last time. When this happens, inThe rusties of dead plant material and other organic compounds in the soil begin to decompose, creating by -products of carbon dioxide and methane gas. This process releases more greenhouse gases into the atmosphere and creates a vicious cycle that snowballs of global warming. Volcanic eruptions also contribute to the presence of gases in the atmosphere.
