汉译英，各位帮帮忙吧，谢谢了

According to the department of energy's an article estimated, in the troposphere (general said atmosphere, water vapor caused by greenhouse effect, accounted for more than 95%. United States Virginia university of environmental science professor and j. Michaels dr estimate is to do the same.
According to the energy department provides a data sheet, man-made carbon dioxide in the total annual production for 231 million tons, and man-made and natural carbon dioxide from the annual total to 7931 million tons. Both XiangChu, artificial parts accounting for all carbon dioxide output 2.91%.
Man-made carbon dioxide for greenhouse contribution is a thousandth more. Earth's temperature changes caused by many factors, never stop the greenhouse effect this item.
Now many scientists think, cosmic rays, or solar activity cycles, through cloud changes with the temperature changes are closely related. The real atmospheric pollution, all kinds of dust particles, obstruct the radiation of the sun, causing climate change coldly. But the recent decades the effective control of environmental pollution, possibly resulting global temperatures rise.

According to an estimate by the US Department of Energy, water vapor in the troposphere (i.e. atmosphere) accounts for 95% of the total greenhouse effect. Patrick J. Michaels, professor of environmental science at Virginia University, has echoed that estimate.
According to a table provided by the Department of Energy, carbon dioxide emission by human activities has reached 23.1 billion tons annually, while the total amount of carbon dioxide produced both naturally and by human activities is 7,931 tons in a year. Dividing the latter with the former and we can see that manmade carbon dioxide accounts for 2.91% of its total amount.
Manmade carbon dioxide accounts for a bit more than one thousandth of global greenhouse effect. There are various reasons for the rise of global temperature, greenhouse effect being one of them. Many scientists today argue that cosmic rays and the solar cycle, through the changes in the cloud cover, are closely related to the variation of the earth’s temperature. And the real air pollution, for example those dust particles, is blocking radiation from the sun hence cooling the climate. It is the effective control over environmental pollution that may have caused global warming.
