2,100. What is the greenhouse effect and how it affects the Earth's climate? The greenhouse effect of the earth's atmosphere is its transparency for the main part of the solar radiation (in the optical range) and Absorption (IR) of the thermal radiation of the planet's surface, warmed by the sun. The determining factor is the presence of carbon dioxide in the atmosphere (carbon dioxide), rather intensively absorbing infrared rays. If the current is now in the air concentration of carbon dioxide will double (from 0.03 to 0.06 percent by volume), it will cause a rise in temperature on the Earth by 3 degrees and lead to the rapid melting of continental glaciers. If the carbon dioxide content will fall by half, respectively, the temperature will drop and glaciers once again reach the latitude of the Crimea and New York.
