as water vapor‚ carbon dioxide‚ and methane keep ground temperatures at a global average of about 60 degrees farenheit. Without them the average would be below the freezing point of water. The gases have this effect because as incoming solar radiation strikes the surface‚ the surface gives off infrared radiation. The effect is comparable to the way in which a greenhouse traps heat and that is how we got the name greenhouse

Global Warming: Fact or Fiction? Is global warming taking place? Are humans the cause of it? Lately these questions are being asked more and more by people who believe that the earth’s climate is growing steadily warmer at an alarming rate. Our planet’s ever-changing climate has captured the attention of those who would have us agree that without drastic modification of our behavior‚ we will ultimately destroy the world in which we live. However‚ these activists are using scare tactics based upon

SUMMARY Global warming is the increase in the average temperature of the earth’s atmosphere. It happens when high level of greenhouse gases like carbon dioxide and methane are trapped in the atmosphere causing a rise in temperature. Although the idea that global warming is similar to climate change‚ there are still some distinctions with these two concepts. As mentioned earlier‚ there is a shift from low temperature to high temperature caused mainly by gases when we speak of global warming. While

It means the list of endangered species only expanding‚ And all habitats anticipate the future taking a crash landing.

Abstract The impacts of global warming vary depending upon perspective and in this paper I will discuss the debate of whether global warming is caused by human activity and carelessness or whether it is just a normal part of the Earth’s natural cyclical processes. Global Warming: Natural or Manmade? Global Warming has been an intriguing and worrisome subject amongst environmentalists‚ scientists and society alike‚ especially in the last few decades‚ but is global warming a topic to raise concern

People are all carrying an umbrella when they step out of house as they cannot stand the blistering heat. This is caused by global warming‚ isn’t it? Global warming has resulted many negative effects and they are mainly caused by human activities. Hence‚ we‚ humans should stop global warming. Human activities produces 75% of annual carbon dioxide emissions. Firstly ‚the greenhouse gases has caused temperatures to increase. Since 1861‚ the average temperature has increased by 0.6 Degree Celsius. Scientists

all of the phony science‚ could it be that man-made global warming is the greatest hoax ever perpetrated on the American people? It sure sounds like it‚” said James M. Inhofe a member of the U.S. Senate. Could this be the true? Many facts behind the controversial issue of global warming prove this statement to correct. Global warming is not caused by human activities. Global warming cannot be completely caused by human’s emission of greenhouse gasses.” In the last 1.6 million years there have been

Global Warming - Fact or Fiction? - Speech The Earth is rapidly heating up or is it? If it is‚ the next few decades may witness Biblical scenes of rising temperatures‚ crop failures‚ flooding and the extinction of different species. On the other hand‚ increases of Carbon Dioxide in our atmosphere may well encourage plants and trees to thrive like never before. Whom can you believe? One thing is certain the debate on climate change and Global Warming is heating up. It is surely right for
