HW:Section D Man And Climate
Answers
Answer:
The economic activity of man has lately been exerting a considerable influence on global climate. This influence ranges from the growth of carbon dioxide concentration to an increase in aerosol chemicals in the atmosphere. The first results in a rise in air temperature at the surface of the earth, while the second provides for a fall in temperature. The overall influence of various man-made factors results in a fall in some tenths of degree in average temperature. Because of a rapid growth of the carbon dioxide concentrations and a growth of energy consumption with an extra heating of the atmosphere, it may be expected that a fall in temperature caused by economic activity will give place to a temperature rise in the near future. According to some calculations an average temperature at the surface of the earth may rise in 0.50 by the end of the present century. It may be followed by a considerable reduction in the area of the Arctic ice, by changes in the atmospheric circulation and by the diminution of precipitation in a number of regions
