Causes And Cosequencesof Probable Global Climate Change

The question of the degree of human influence on its environment has always interested philosophers and scientists. Abnormal natural phenomena, a growing number of natural disasters, and significant temperature fluctuations raise questions about global climate change now. Many of them are caused by natural factors. However, a significant group of scientists talks about increasing human influence on the climate. The nature of the changes is not clearly defined. A large number of representatives of the scientific world believe that the era of warming comes.

But a group of scientists believes that the ice age is a likely scenario. Various theories about the causes and consequences put forward.

The trend of increasing air temperature observed since the late 19th century. A further increase in average temperature is associated with the expansion of the industry. Carbon dioxide is the main product of the combustion of hydrocarbon fuels. An increase in the level of carbon dioxide, methane, ozone, and water vapor leads to delaying the thermal cure at the earth's surface.

There are natural sources of greenhouse gas emissions: volcanic activity is already at the bottom of oceans, evaporation of biological origin. However, the raising in global temperature is associated with anthropogenic activities.

An international group of experts created by the UN has determined that a further increase in atmospheric temperature of more than 2 degrees can be fatal. The mass of ice and snow will become a critical minimum. Many coastal towns of the United States, Japan, Baltic countries, and island States may be completely inundated.

This may be the cause of significant economic and geopolitical problems. The freshwater supply may be greatly reduced. The water balance of the planet can be disrupted. Many species, especially endemic species may disappear.

A group of scientists suggests that the Earth has entered a period of cooling. The proponents of this theory believe that natural factors are the main cause of climate change. Large-scale geological studies confirm that global changes in climate occurred repeatedly. According to observations by Russian researchers over the snow cover of Antarctica, the volume of ice and snow over the past 30-40 years has raised. Scientists have developed a theory based on climatic factors from periods of solar activity, and the reflectivity of the Earth.

In the early twentieth century astrophysicist, M. Milankovitch investigated the cause of the occurrence of ice ages on Earth. He established a correlation between the advent of a cold snap and the change in the shape of Earth's orbit. Three positional cycles of various durations were identified that affect the Earth’s climate. According to Milankovitch’s cycles, the Earth is now in a relatively cool phase. Many modern studies of perennial ice confirm the theory of M. Milankovich.

There are several possible consequences of the onset of the Ice Age. Many areas will be unsuitable for living. The number of natural disasters will increase.

Climatic changes are characteristic of the history of the Earth. This is due to cosmic phenomena, geological activity, tectonic disturbances, and human activity. Many specialists confirm that changes in climatic conditions at the present stage of development are real. Humanity must be prepared to withstand this. There are government programs for the sustainable development of countries. Implementation plans should be developed and implemented. Many countries have high hopes for young scientists and students.
