The Trend of Global Temperature Polarization

Global temperature polarization means that the world is becoming either hotter or colder seriously (Fei Wen, 2012). There is a disputation with respect to the change of temperature. Some think that warming is the trend, while the other holds the opposite opinion. Since temperature plays an important role in people’s life, and it exerts a strong impact not only on their health, but also on the environment of the world, it is necessary to find out which theory can make a more precise prediction of the future.

The impact of weather will always touch people’s feeling directly. These years, there are a lot of complaints on either the extreme high temperature or the extreme low temperature. Also Polarization weather has strong destructive and sudden, unpredictable characteristics. People must pay greater attention to this abnormal temperature. These years, due to the increase of the frequency and strength of polarization weather, polarization becomes more serious. The power of the temperature is enormous no matter you care about it or not.

Besides, the temperature changes have tremendous impacts on the human beings, which is related to daily life. It may cause a reduction in grain yield, farmland obscene even food crisis. People must prevent the temperature’s change from getting worse and in order to ensure the living environment. The temperature also influences rainfall. How the temperature affects the rainfall is composite in different areas. The change of rainfall in seaside is more quickly than what in inland areas, but the evaporation capacity change in inland will be shown directly. An example shows that there has not been much change in rainfall in those inland areas, but the temperature has risen by over 1 degree Centigrade since 1970, which will have enhanced losses due to evaporation.

We are aware that water vapor in the atmosphere produces the strongest greenhouse effect, but it has been in balance for millions of years. The increase in carbon dioxide in the atmosphere arising from the burning of coal and oil is creating a greenhouse effect, and raising the world's average temperature. Coal is king in China and India, and coal is a very unscrupulous producer of greenhouse gases. Owing to the global temperature polarization, higher amounts of heat-trapping gases in the atmosphere can explain why the greenhouse effect increased these years. We must face the facts: our emissions of greenhouse gases probably are at least partly to be responsible for this winter of extremes.

We have the experience of extreme temperatures. In the United States, we are experiencing rain and snow freeze disaster that we rarely see. The serious weather phenomenon influenced in our daily life lets us know the great power of the temperature. In China, most areas are experiencing the longest scoreless period in winter due to temperature change. Even my grandmother said this was what she never saw in her 70-year life. These experiences made me more and more realized that the importance of the temperature polarization.

Because of the worsening global temperature polarization, people pay more and more attention on the temperature. Extremely elevated temperature is one of the features in the global temperature polarization. With temperatures rising and more water vapor in the air, such storms can pull in more moisture and thus rain or snow more heavily than storms of childhood. This winter in the eastern United States was a great case, use my own experience as an example, I think the temperature is much more colder than before. What I saw and felt let me awed by the power of nature, which is what makes me touch the life under the terrible temperature. I have never felt colder than this weather. Whether the temperature is getting warmer or cooler in the future becomes a major issue. I agree more with the viewpoint of warming trend. This is an important question for us to think about, so we must pay more attention on it.

In my investigation, I will go to Purdue libraries and search online to get some information on the climate change. The most statement said the trend of the global temperature is warming; global warming is a kind of climate in our life. And they said that the global warming is due to the increase of the carbon dioxide and other greenhouse gases effect; the temperature of the globe is increasing constantly. Besides, since I am taking EAPS100 this semester, a class on earth science, I will interview my geography professor about his opinion on the area of the trend of global temperature polarization. I think my geography teacher of EAPS100 is a really good teacher in Purdue University.
