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.
Global warming is a major ecological concern today. It is being caused by man’s ever
First, during the last few decades the Earth is experiencing greater rate of rising temperatures due to greenhouse gases that are being produced by human activities rather than because of environmental reasons, such as solar or volcanic activities. In 2006 the President of the National Academy of Sciences stated: “There is no doubt that the Earth is warming,” also he added that people are at least partly responsible for these changes in addition to regular factors (Cicerone, par.4). Natural factors have produced climate fluctuations on Earth for several million years. People have effected an atmosphere of the Earth just for nearly one hundred years, since Industrial Revolution has begun (Revkin 340). Of course, it is unfair to say that global warming is caused entirely by humans. For example, people can not have an impact on the position of Earth in relation to the sun, or on the galactic density, or such nature events as air emissions of volcanic gases. As a result of these environmental factors, Earth usually had higher rates of temperature fluctuations during the previous million years than it has in later centuries. On the other hand, people are responsible for the highest concentration of greenhouse gases during the last 650,000 years in the atmosphere due to industrial manufacturing, driven by the increase in consumer consumption (Lindsey, par.
Our world faces many issues consisting of political issues, economic crisis, poverty, world wars, and environmental issues for example. Global warming is one of the many environment issues that many pay little attention to. Mr. Al Gore in his documentary directed by David Guggenheim brings to light this climate crisis and how affective it can be to the earth and how we must address it as soon as possible as it may lead to the destruction of our world’s environment. Al Gore does a great job in identifying global warming, what are the cause and effects, and how we should address the issue that can potentially save our planet earth. Overall, Al Gore offers a credible argument and one of the many reasons Al Gore’s argument is credible is because
Portions of the United States experienced an exceptionally cold winter this year. Here in North Carolina we had three months of overnight temperature below freezing with temperatures in the 20s. I have lived in the Raleigh area for 25 years and have never experienced a winter so consistently cold with thick layers of ice on windshields every morning and frost on the roofs of homes that remained frozen until the middle of the morning. The act of cleaning up snow and ice brought back memories of growing up in the 1960s in the far north of New Jersey where temperatures remained below freezing for months and the ice on local lakes was solid enough to support the weight of a tractor to plow away the snow so everyone could ice skate, and we did skate there for at least two months. Recent winters in my hometown have been so mild that the lake did not freeze at all and even the Canada geese did not migrate south, but remained there in NJ. This winter, while we were freezing inside our homes back here in Raleigh, the news media continued to debate the global warming issue. The conflict between the weather outside for me vs. the news reports of global warming made me pause and question where the truth lies. My research uncovered that global warming is very real and, in fact, explains the shift in air currents that caused the extreme weather this winter that is negatively impacting millions of lives. In conclusion, the time is now when politicians must legislate strong actions to minimize man’s contribution to global warming and enact measures to provide emergency assistance wherever these violent weather patterns cause crises.
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
For a majority of people, it isn’t new news that the Earth’s climate is changing and increasingly getting warmer. For quite some time now, people have been arguing about what the actual causes are and what role humans have played in the current condition of the earth. A good bit of people seem to be in agreement that due to the actions of humans, the earth’s climate is increasingly getting worse and that if things don’t change, than everyone living on earth will be facing the consequences. However, this is not entirely true. The fault of climate change does not fall solely on the shoulders of mankind, but on the earth as well.
For years to come there will always be a speculation on whether the climate change has really taken place or not. Many believe that large companies launched this topic in order to benefit from it in profit, as there are also those who are convinced that this are consequences that have emerged from human mistakes in understanding the environment. As humans are struggling to trust one another whether it is just a big conspiracy or not or environment changing itself, we are slowly starting to feel the effects of climate change. Because of the gasses (CO2) that are in the air, atmosphere is getting warmer, thereby triggering the Greenhouse effect. Almost 70% of emitted gasses in air are CO2, which leads us to believe that this is the main cause of Global Warming. Since it is billions and billions of metric tons per year that are being released in air, many scientists conclude that temperature will most likely be more higher in twenty years from now, than it was in near past.
Throughout history climates have drastically changed. There have been shifts from warm climates to the Ice Ages (Cunningham & Cunningham, 2009, p.204). Evidence suggests there have been at least a dozen abrupt climate changes throughout the history of the earth. There are a few suspected reasons for these past climate changes. One reason may be that asteroids hitting the earth and volcanic eruptions caused some of them. A further assumption is that 22-year solar magnetic cycles and 11-year sunspot cycles played a part in the changes. A further possibility is that a regular shifting in the angle of the moon orbiting earth causing changing tides and atmospheric circulation affects the global climate (Cunningham & Cunningham, 2009, p.205). Scientific studies suggest that all these played a role in past global warming and cooling periods. Today, however, there is a lot of conflict on whether humans are causing a global warming that could be disastrous to humans and all species of plants and animals on this earth. This paper will first explain the greenhouse effect, then take a look at both sides argument, and, finally, analyze the effect of global warming on world-wide sustainability
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.
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.
Global warming is one of the most serious issues that the human species face today, yet the majority of the population does not pay attention to it. People are not aware of the dangers and do not care about it much because the main effects will affect the next generation and not themselves. Global warming is happening and it is the reason for changing weather and weather extremes such as earthquakes, floods and wildfires. Global warming is caused by societies lifestyle and these lifestyles destroy the environment and affect the whole world. The use of cars, trains, planes, as well as wasting energy for people’s entertainment has a price; this price is that society is in danger.
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
