The Global Warming Debate
In the beginning of the twentieth century scientist had started talk that the globe is warming and man is the cause. Then news stations of course took the idea and made it sound like the worst thing since World War II. The thought of the globe warming is frightening the American people and people all over the world because the scientists and the news blew it out of proportion. Although it is believed that man’s carbon emissions are the cause of global waring, in reality the global cycle of nature causes the climate to change and also provides benefits to life on Earth.
Global warming extremists voice that man’s factories, automobiles, and industrial activity produce enough carbon dioxide to cause the global temperature to warm. The connection between carbon dioxide and temperature rise is very small. This was proven in the 1960’s and 1970’s when the greenhouse gas, carbon dioxide was on the rise and the global temperature still ended up cooler for the decade (Biley 78). Another aspect to look at is that Earth’s main warming cycle took place before the 1940’s, before 80 percent of man’s carbon emissions were put in the air, which means that the emissions had little impact on the temperature if any (Biley 133). Even more evidence that shows global warming is not caused by man is that at the Oregon Institution of Science and Medicine 17,000 scientists signed a petition that stated there is no evidence of global warming being caused by man’s output of greenhouse gasses (Biley 44). Some may think that global warming is a serious problem on Earth but man should not be to blame over the very little fluctuations of the global temperature caused...

...son is longer their is more rain all and the winters are mild so their is not much killing of crops (Biley 111). Some may think that the warmer climate would kill the crops because of a drought, but there has been no water shortage and average summer temperatures around the world still remained normal (Biley 111). These are just some of the benefits global warming can offer to life on Earth which global warming extremists tend to overlook.
Scientists will always find new statistics about global warming and make claims that are both true and false. There is already enough evidence to belittle man’s carbon output as a significant cause of global warming and say that natural forces cause it and can make life beneficial. The only thing we know for sure is that global warming is a serious topic in the world today and always is going to be debated no matter what.
Many of the scientists believe that earth is getting hotter, and the average temperature of earth is increasing each year due to the excessive burning of fuels on earth. The idea that the earth’s temperature is increasing is called global warming, and humans are the main cause of it. In spite of this theory, many believe that there is no global warming because the surface temperature has not increased steadily, but documents and researches show that global warming is real, and it is endangering lives of the animals on the earth.
The Earth's climate has changed significantly throughout history. In the last 700,000 years there have been seven cycles of glacial advance and retreat. With the abrupt end of the last ice age approximately 7,000 years ago the beginning of the modern climate era was born. In the last century the global sea level has risen 17cm. All three major global surface temperature reconstructions show that Earth has warmed since 1880. Most of this warming has occurred since the 1970s, with the 20 warmest years, having occurred since 1981 and with all 10 of the warmest years occurring in the past 12 years. There is no denying global warming. Once considered a conspiracy theory by the world’s leading governments, industries and populations; global warming
The cause of global warming has been a debate between scientists and experts for numerous years. In fact, Svante August Arrhenius, a Swedish chemist, first predicted global warming would occur in 1896 (Harris 16). Researchers who agree it is naturally caused insist the greenhouse effect has many natural causes. Others agree that the cause of the Earth’s increase in temperature is just part of a continuous cycle. These researchers argue that solar activity plays a huge role in the issue of global warming. Therefore, based upon the myth of the greenhouse effect, cyclical patterns, and research on solar activity, global warming is not a man-made dilemma.
Global warming is a topic of discussion that many people can debate or try to avoid. It is often argued that the causes of global warming are either caused by humans, nature, or both. Some of these people don’t even have a clue about the impact they have on Earth and the ozone layer. Some people may not even know what causes global warming. If people don’t know how they are contributing to global warming, how are they going to contribute to stop it? Humans affect global warming by activities that range from driving to expanding their family. In this case, global warming’s effects are overwhelmingly connected to human activity.
The world is warming up. The Intergovernmental Panel on Climate Change (IPCC) has declared that the cause of the warming is human emission of certain gases into the atmosphere. The verdict of the IPCC is widely, but not universally, accepted. A small minority of scientists reject the finding of IPCC and propose that global warming is driven by the sun. Some also charge that IPCC is driven by a political agenda. These dissidents are beginning to get a public hearing. It is important that this matter be debated openly.
The negative side of global warming is that it leads to melting of ice. The world's glaciers, especially Arctic glaciers are melting faster than new snow and ice can supplement them. During the melting of Arctic ice opens over the dark surface of the water or soil and balance change reflects less and absorb a greater amount of heat, therefore, large areas of ice melt rapidly (News, global warming). There is evidence, which will support this argument: scientists from the University of California in San Diego investigated satellite observation data for the Arctic for 1979-2011 years. Since the 1970s, the area covering of the ice has decreased by 40 % and the region has warmed up to 2 degrees (News global warming).It means, that global warming affects to the wildli...
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.
Climate change is a hot topic with many people saying that the humans are making the world's temperature increase and other saying it’s a natural cycle. Climate change can be very dangerous because it can make environments to hostile to certain plants or animals and it also can make the sea level increase witch would put many cities in danger.. The people that believe that the humans are to blame state that the amount of CO₂ that humans emit into the atmosphere and deforestation are the main problems that we are currently doing. Whilst the people that say its a natural process say that is a natural cycle and we are just unfortunate to experience this in our lifetime. In this debate the evidence seems to side with the people saying that the humans are the cause.
After viewing Climate of Doubt, it’s quite clear that the debate of climate change has quite the history. Dating back to 2007, there have been global warming advocates. The issue, however, arises from the opposing groups. On the side of global warming advocates, they are often depicted as “tree-hugging liberals.” On the other side, you have those depicted as “heartless science denying conservatives.” It’s within these opposing sides where you see the reason for a contentious debate. Each of the sides are constantly trying to poke holes in science and deny blatant truth. For example, the documentary highlights the “climategate.” It is explained that climategate was an email controversy where emails were taken out of context to combat climate
One of the hottest controversial topics right now is global warming, and it is only getting “hotter”. Everything about this topic is debated; how should we deal with it, what causes, and does it even exist?! First of all, global warming is the overall rise in the Earth’s temperature over time. These changes in temperature are happening more and more rapidly, and there is a clear reason why. That reason is us. Every second we emit about 2.4 million pounds of a harmful gas into the atmosphere. This dangerous gas is carbon dioxide (CO2), which is a gas we are casting out into the air through many of our daily activities and it is causing dangerous effects. While this effects are daunting, we are able to fix them. If we are willing to change. I
Scientists all over the world are preoccupied with the problem of global warming which can lead to disastrous consequences. That is why people should curb the global warming and climate change evaluating the current situation properly and correctly. The global warming is associated with the rise of the Earth’s temperature resulting in the accelerating sea levels causing flooding in the world and bringing much trouble for people ruining their property and homes. That is why people living in the world should understand the threat posed by global warming.
Many climate scientists, researchers, and environmentalists are expressing concerns about shifts in the overall climate of the earth. It is believed that a dramatically dangerous warming is taking place in the overall global climate, a problem that is referred to as "global warming”. Global warming is the observed century-scale rise in the average temperature of Earth’s climate system. This temperature rise is due to the damaging effects of deforestation and the burning of fossil fuels. It is our responsibility to preserve our planet and our way of living but in order to do that we need to act now. If we continue to destroy the planet with no regard as to how serious this matter is there could be several negative effects to us as human being and other living thing on Earth. This is why global warming is truly a global issue and needs to be tackled collectively. We must to act now in order to reduce the dangerous levels of carbon dioxide emissions and we must to work together.
Global warming has become on of the most controversial issues in the media today. While most of the Western world countries have generally accepted the premise that man's chemical emissions in the atmosphere can and are affected by the world’s climate patterns, in the United States, the issue has become so politicized with many republicans challenging the science behind the theory. Global warming is a greenhouse effect whereby gases are trapped on the earth’s surface causing it to heat up (Maslin 14). It is based on the worldwide temperature records that have been maintained by human beings through their activities since the 1880,s. In addition, global warming is not only caused by human activities only but also through climate changes in solar radiance. The problem is that, humans continue to contribute to the global warming phenomenon. All citizens should work in reducing human activities that cause global warming and also support the development of nuclear power. Scientists deem that, global warming is mainly caused by human activities which accelerate the natural process by creating greenhouse gases in the atmosphere. Human activities have become a great contribution to the greenhouse effect and this means that climate changes are inevitable. They further argue that, if these activities continue and are not reduced, it will lead to more trapping of energy radiated from the earth and this will likely lead to extreme weather and global warming. Global warming should be at reduced levels or else, it will be catastrophic.
Our planet has managed to survive and thrive for about 4.54 billion years. In the last 2 million years we have caused enough damage and destruction to make our world “broken” beyond repair. We will not be able to get back the world we once had. The reason behind this is global warming, specifically, the increase of the global temperature due to the burning of fossil fuels and the release of greenhouse gas emissions into our atmosphere. If we do not make the issue of global warming a priority in today`s society, our entire way of life will be at risk. There are many reasons why so many people believe global warming should be a concern. Thoroughly examined points include: scientific predictions, rising temperatures, human causes, drastic climate changes and animal adaptations. Though there are several points arguing how global warming should not be a concern, the reality of the matter is that it needs to be taken into consideration on a global scale before it is too late, as to do nothing would have devastating implications on humankind.
One of the most substantial problems in the world today is global warming. This gradual warming of the earth is in occurrence at an extremely slow rate but it is happening. Many scientists believe that as human’s work and release greenhouse gases into the earth’s atmosphere, it can become dangerous for the long lasting life of humans and our environment. “Unless we take immediate action, the impacts of global warming will continue to intensify, grow ever more costly and damaging, and increasingly affect the entire planet - including you, your community, and your family” (“Global Warming Impacts”). Everyone should be knowledgeable about global warming and the dangers that it brings to our planet. This essay will examine
