Global warming is a topic that is increasingly occupying the attention of the world nowadays. Is it really happening? Is it really caused due to the human activities? Is it the cause for the irregularities in weather and climate these days? Or is it a conspiracy planned by the developed countries to prevent the developing countries from establishing themselves in the modern world? What’s the truth behind it? The documentary films “An inconvenient truth” by Davis Guggenheim and “The great global warming swindle” by Martin Durkin state contradicting opinions on this topic. In the documentary “An inconvenient truth” Al Gore, the ex-vice president of the USA discusses the present and future effects of global warming and the consequences that we will incur if the amount of the greenhouse gases generated is not reduced in the future. The documentary “The great global warming swindle” asserts that the concept of global warming is a big lie and it is one of the biggest scam of the human history. They suggest that the scientific opinion on climate change is influenced by political factors. The first documentary states that the sun radiation that hits the earth is reflected back by its surface. But some of the reflected infrared radiation is trapped by the earth atmosphere and keeps the earth warm. The green houses gases released into the atmosphere thickens it and are responsible for the rise of temperatures. In the other documentary we come to know that the greenhouse gases trap the radiation in the middle of the troposphere some 10-12 kms from the earth surface. So according to the climate models it’s here the rate of warming should be the highest if it’s the greenhouse gas that is causing it according to ... ... middle of paper ... ...es into the atmosphere. All the proposed methods to reduce global warming such as using recyclable products, using less quantity of fossil fuels, using energy efficient products, planting more number of trees, reduced use of paper products, and many other methods always help the environment irrespective of whether global warming causes the climate variations or not. If people think that global warming is not the cause of these climate variations and do not try to reduce the emission of greenhouse gases and what will happen if it is indeed global warming the main culprit for the cause of these climate variations. We cannot risk the future of the earth based on points which we do not know whether they are true or not. It is better to follow these methods than not following them. It is wise to reduce the emissions of these unwanted greenhouse gases into the atmosphere.

    Global Warming - A Problem Blown Out of Proportion It is ironic that fifty two years before hosting the 1997 United Nations Conference on Climate Change, the city of Kyoto had barely missed being destroyed. It was one of four cities considered as primary targets by President Harry Truman’s secretary of war, Henry L. Stimson. The others were Kokura, Hiroshima, and Niigata. Gale E. Christianson describes Kyoto in her book Greenhouse as a magnificent city surpassed only by Tokyo in the number of its institutions of higher learning.

  • Fiery Future Of Climate Change By Tim Dickinson

    Global warming is a scientific, political, and controversial topic. Some believe it is catastrophic, a slow moving killer hiding in the shadows. Others do not even think twice about it as they race by in a Hummer. Global warming is the gradual increase of temperature throughout different climates. It is caused by the greenhouse gas effect in which greenhouse gases, like methane and carbon dioxide, reflect sunlight back and forth. This reflected ultraviolet light bounces between the earth and the ozone layer and becomes trapped, resulting in a gradual rise of temperature. Over time, the slow rise of temperature causes new climates throughout the globe. The article “What Megablazes Tell Us About the Fiery Future of Climate Change” by Tim Dickinson

    It's no surprise to most people that the idea of global warming is a highly controversial and debated topic. But is there any real evidence that global warming is a growing problem or is global warming just a big scare tactic being used to get people to comply with strict government regulations? Global warming is widely believed to be the main cause of rising average global temperatures. In reality, global warming isn't really all what it has been exaggerated to be. Many of the predicted effects of global warming over time have actually been proven to be false all together.

  • The Dangers Of Climate Change

    Climate change has been nothing, but controversial in the last fifty years. Climate change is a change in the average weather of a region or city. Scientists have opted to use the term "climate change" instead of global warming because as the Earth's average temperature changes, winds and ocean currents move heat around the globe in ways that can cool some areas, as well as warm others. There is an ongoing dispute about the effects of humans on the global climate and about what policies should be implemented to avoid possible undesirable effects of climate change. Ninety-seven percent of published scientific research concluded that climate change is real, problematic for the planet, and has been exacerbated by human activity. But what about the three percent that contradicts that?

    First is a description of the greenhouse effect. The earth’s atmosphere has four layers, or zones, with each having distinct differences in temperature. The troposphere is the first layer surrounding the earth. Within this layer air is continually circulating and moving heat and moisture around the earth. The troposphere is denser than the other layers due to the fact that gravity keeps the majority of air molecules near the earth. This is about 75 percent of all the atmospheric mass. It is also the warmest layer (Cunningham & Cunningham, ...

    The subject of global warming is as popular as the president. These both topics have always been hot subjects in everyday life. Global warming is the biggest storm headed in our way. It is also the most important issue of our times. Those ads or public service announcement on TV about global warming might not be the most attractive but the cause behind it is very important. Global warming is one of the major threats our planet is facing. Most scientists prove the fact that global warming is mainly caused by human activities rather than natural cycles. To simplify it, most mechanisms that we use are affecting earth. These mechanisms are created by humans. Therefore, humans are affecting earth.

    Al Gore also notices that the ten hottest years on record have occurred in the last 14 years. He gives many examples such as the massive heat wave in Europe, the dramatic high temperature in India and a lot of cities in America. The temperature increases are occupied in the whole world, not only the land but also the oceans. When the oceans get warmer, that causes stronger storms. In the last couple years, there are a lot of big hurricanes. These catastrophic disasters did a lot of damages. They lead to more flooding, heavy rain. However, they also lead to more drought. The spring comes earlier and the fall comes later, the temperature keeps on going up. Many explorers found that the ice is less thick than before. Mr. Al Gore uses a lot of scientific and geographic knowledge to explain the cause and the consequence about the global warming. Ecological environment has been influenced and many rare animals are endangered. Many mosquitos change their habitats and expand their range owning to the change of temperature. Also, it causes a lot of vectors for infectious diseases. It is often said that human should save water and water is a necessary. However, most people never notice that many droughts were caused by global warming. The explanation in the movie is very convince and persuasive. When I was a senior high school student, our geography teacher told us global warming not only makes the temperature high, but also makes many potential dangers. As I was a child, there is a catastrophic disease named SARS, my mother told me that the disease was very serious and led a lot of people to die. If we have to go out, we should be well-armed. We need to use masks to keep us from the virus. From this case, SARS is a disaster and from this movie, global warming is also a

    The Great Global Warming Swindle has been the most widely watched documentary critical of the scientific consensus that climate change is due to anthropogenic activities. Aired in 2007 in the United Kingdom, the documentary claimed to debunk the “myth” of manmade global climate change, exposing it as a vast conspiracy designed to gain funding for research and push an environmental agenda that is especially harmful to the developing world. Directed by British producer Martin Durkin, the documentary includes discussion with a number of scientists who are skeptical of anthropogenic global warming and claim that there viewpoints are being deliberately censored in favor of the politically correct consensus.

Over 31,000 scientists have signed on to a petition saying humans aren't causing global warming. More than 1000 scientists signed on to another report saying there is no global warming at all. There are tens of thousands of well-educated, mainstream scientists who do not agree that global warming is occurring at all. If so many scientists believe it is not a concern then why should we think any different? Well, a consensus shows that in reality 97% of all climate scientists agree that global warming is an issue and that it is most likely due to ...

    While this may contain some truth, most believe that the causes of aerosol, fossil fuels, and the greenhouse effect are the reasons for global warming. These causes can easily be reduced if we take the time and effort to halt the action. Simple actions can be made that will not have a severe effect on our everyday lives. Al Gore once said, "The good news is, we have everything we need now to respond to the challenge of global warming. " We have all the technologies we need, more are being developed but we should not wait, we cannot wait, we must not wait.”

    Scientists blame the greenhouse gas effect in combination with societies greenhouse gas emissions for the rising temperature. The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions. Since part of this re-radiation is emitted back towards the earth’s surface and the lower atmosphere, it results in an elevation of the average surface temperature above what it would be in the absence of the gases (Intergovernmental Panel on Climate Change). Simply, global... ... middle of paper ... ... of extreme weather and melting ice caps are indicators of global warming.
