Since global warming appeared during the last decade as a serious environmental issue‚ it has been the subject of a lot of debate. Global warming is defined as the warming of the earth by greenhouse gases emitted into the atmosphere. But there are many questions about global warming‚ from its causes to its effects. Many people even question whether or not global warming exists. And if global warming does exist‚ people question why it exists. Well‚ there are two different viewpoints. The believers

GLOBAL WARMING One of the most strongly debated topics on our earth is the issue of climate change. Global warming and climate change is refer to an increase in average global temperatures. Natural events and human activities are believed to be contributing to an increase in average global temperatures. This is caused primarily by increases in “greenhouse” gases such as Carbon Dioxide (CO2) I. Effect There are two effects of global warming which is the environmental and social changes

Global Warming Global warming is the increase of world’s average temperature‚ mainly in the sector of atmosphere‚ seas and the land on Earth. here are three serious factor‚ namely the crack on the lower part of atmosphere‚ pollution on Earth an so many green houses. The first factor is on the atmosphere. Recent years‚ many researches show that atmosphere has some kind of crack because of the heat from sun’s emission. The layer of atmosphere seems can not take the heat anymore. The crack gets larger

Through the eyes of most scientists‚ global warming is seen as a very serious and severe threat. The actions taken by humans‚ such as industry and consumption of fossil fuels plus the increase in population and agriculture have played a big part in global warming. If something is not done soon the results could be very bad. By the middle of the twenty first century‚ there is evidence that the Earth will be warmer than it has been at any time in human history‚ and quite possibly since the

OF GLOBAL WARMING Global warming is defined as an increase in the average temperature of the Earth’s atmosphere‚ especially a sustained increase great enough to cause changes in the global climate. The term global warming is synonymous with Enhanced green house effect‚ implying an increase in the amount of green house gases in the earth’s atmosphere‚ leading to entrapment of more and more solar radiations‚ and thus increasing the overall temperature of the earth.

Global warming You have probably heard about the phrase “global warming” hundreds of times. But what exactly does global warming means? Global warming is not about having a hot day or week or month in one part of the world. It has to do with the average temperature worldwide. Simply put‚ global warming is the unusual rapid increase in earth’s average temperature worldwide. The warming of the earth began in the mid 1800’s. In the beginning it was small and very slow but then in the 1980’s the

Global Warming Global warming means a gradual increase in the Earth’s average lower atmosphere due to emissions and build up of greenhouse gases . Global warming is when the earth heats up and the temperature rises. It happens when greenhouse gases such as carbon dioxide‚ water vapor‚ nitrous oxide‚ and methane trap heat and light from the sun in the earth’s atmosphere‚ which increases the temperature. Most greenhouse gases are released by the burning of fossil fuels for heating‚ cooking‚ electrical

We could all come together as one and leave all our differences of color‚ religion‚ and political views behind us‚ to stand together to face what Bill McKibben calls the greatest challenge and threat mankind has ever faced: global warming. In 2007 Bill McKibben‚ an author‚ educator‚ and environmentalist‚ wrote the article‚ “Global Warning: Get Up! Stand

I Introduction My awareness of the phenomenon called either "global warming" or "climate change" started immediately before the Kyoto Summit in December 1997. I read articles in the media which said that many scientists believe that the threat of global arming was alarming and that our political leaders would have to do something in order to prevent the climate from getting hotter and hotter. Since this conference climate change has fascinated me. This research paper is divided into two main parts:
