Since late 1800 scientists have studied the phenomenon of Global Warming and majority of them had concluded that human activities are responsible for most of the warming. Human activities contribute to global warming by enhancing earth’s natural greenhouse effect. The greenhouse effect warms the earth surface through the complex process involving sunlight, gases and particles in the atmosphere. Gases that trap heat in the atmosphere are known as greenhouse gases like carbon dioxide, methane, nitrous oxide, and fluorinated gases. There are few scientists who argue that the increase in the greenhouse gases had not made a measurable difference in the climate. Therefore the claim that human activities are causing the global climatic to warm significantly is irrational. However, scientists would like to see a clear mirror image of the global warming which threatens our environment; if you are uncertain about the remarks made by them. I would like to show you both sides of the mirror.
Global warming is rise in the temperature of earth’s surface because of the greenhouse gases that get trapped in the atmosphere. This is like on a very hot day heat gets trapped inside the car. The increase in temperature of the climate is due to increase of human activities by burning of the fossil fuels; the serious environmental threat as described by Ross Gelbspan, a Pulitzer Prize-winning journalist and author of The Heat Is On: The Climate Crisis. Opposing his view that the human activities are causing the global climate to warm is not the serious environmental threat by S. Fred Singer, head of Science and Environmental Policy Project, and director of the U.S. Weather Satellite Service. His books include Hot Talk, Cold Science: Global Warming Unfini...

These authors surely show us different sides of the mirror about global warming. Gelbspan supports to fight against the global warming, where slightest increases of greenhouse gases will have a profound effect on the global climate which can lead to catastrophic events in the future. He also calls for the solution by reducing the emission of harmful gases and turning to eco-friendly products. Whereas Singer contends that the slight rise of temperature is natural process and will not lead to significant changes in the climate. Instead these changes will benefit agricultural crops to grow. He also argues that not all the theory is fully understood and statistical data established by IPCC is unreliable. This is a never-ending debate and all we can hope that our planet thrives prosperously with all its natural resources.
Global warming is the rise in average temperature of Earth’s atmosphere and oceans. If the warming continues it will have drastic effects on our lives in the future. Things such as harsher summers and colder winters will become a reality for future generations. Global warming is real, despite what the naysayers say, and it will affect us in many different ways if we can’t solve this problem. By presenting skeptics arguments about global warming I’ll prove global warming to be real by disproving them.
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.
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
Kenneth Hare reviews the scientific evidence on the greenhouse effect and explained that warming on global and increased greenhouse gases is the main issue that impact climate change. Human activity is the one who causes the greenhouse effect. The natural greenhouse effect is benefit to our world and become probable to making life on earth, but the temperature is very high nowadays that harm human, plant, and animal life. For example, the natural resource such as petrol for vehicles and electricity for our necessary needs will produce more than billions of carbon to the atmosphere every year that cause climate change every day in our earth.
Global warming is an increase of carbon dioxide, nitrous oxide and methane disrupting the earth’s ecosystem ultimately causing climate changes, this is just one of the tradeoffs of the modern life we live. Some doubt that global warming is a real issue despite the increasing natural disasters, freak weather and populations of species becoming extinct. Global warming is one of the challenges that we are facing today, it is much like the climate changes faced in the past but our climate is changing more rapidly. Wi...
Over the past years, planet Earth has been warming up. According to NASA's Goddard Institute for Space Studies, average temperatures have risen around1.4 degrees Fahrenheit/0.8 degrees Celsius since 1880. In fact, the rate of warming is increasing. It was reported by a number of climate studies that the last two decades were the hottest in 400 years. Global warming is a major threat to the planet. It is agreed that humans have caused most of the past century's warming by releasing greenhouse gasses, as we power our electronic lives. The “greenhouse effect” is performed when the gasses let out into Earth’s atmosphere trap heat from the sun. Through the burning of fossil fuels, humans are enhancing the greenhouse effect and increasing the temperatures of the planet. Although the greenhouse effect is what keeps the planet warm, thereby supporting life, too much would also result in severe issues. Now, with the increasing rate of greenhouse gases emissions, frozen glaciers are melting, sea levels are rising, and wildlife is scrambling to keep up with the fast pace. Above that, weather can also become more and more extreme. Something has to be done.
Over the last few years almost everyone has heard that the earth is warming. Also, almost everyone has heard the pleas to go green and reduce carbon emissions, led by former Vice-President Al Gore. Even though there is not a truly accurate definition of global warming it can be roughly defined as a rise in average global temperature according to Laurence Pringle’s book Global Warming Assessing the Greenhouse Threat (19). Global Warming Assessing the Greenhouse Threat also bring up that the average temperature data that scientist are using only goes back to 1860 giving scientists today only 150 years of temperature data. Also, with this current warming, even with humans contributing to the rising average global temperature, scientist today do not fully understand all the complexities of the atmosphere (Pringle 19-21). According to another book by Mr. Pringle, Global Warming the Threat of Earth’s Changing Climate, scientists predict global temperatures could rise from two to six degrees Celsius by 2050 (33). Despite these predictions historical and new information show that scientist are incorrect that global temperatures will forever continue to increase. Global warming and the rise in global temperatures is due to humans burning fossil fuels and overconsumption of products, as well as natural cycles changing slightly and other natural phenomenon; however, this warming will eventually lead to global cooling.
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 scientific definition of global climate change is a long-term change in the earth’s climate due to an increase in the average atmospheric temperature. The facts about the global climate change are known throughout the scientific community, but not well known in the public and those facts are going be explained in this essay. Either the two reasons that people use for the global climate change are that it is the human species’ fault or it is a natural course of the environment. Both of sides of the argument are going to be explained depth in this essay, too. Global climate change, also known incorrectly as global warming, is not a debate about whether or not it exists. It is a debate about whether it is the human species’ fault or if it is an effect of the natural processes.
Over time, scientists have been able to perform studies and gather the information as to what exactly causes global warming. Scientists have collectively agreed that humans are the main cause of global warming is human produced. Humans burn coal, oil, and other gases to create energy. In doing so, this creates excess carbons that warm the atmosphere that block the heat from escaping the Earth (Climate Change Causes: A Blanket around the Earth). This process is known as the greenhouse effect. Other gasses that contribute to the greenhouse effect include water vapor, carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons (Climate Change Causes: A Blanket around the Earth). Another human activity that contributes to global warming is
Global warming and global climate change is the study of future increases of temperature across the globe. Studying climate change refers to how the over- all climate will change such as the dry places getting dryer and the wet places getting wetter. Global climate is dependent on “the greenhouse effect a natural process that helps regulate temperature” (Easterling and Karl). In the past few centuries humans have had a monumental effect on increasing of greenhouse gases in the atmosphere. Climate change is result of the increase amount of the greenhouse gasses in the atmosphere such as methane, carbon dioxide, water vapor, nitrous oxide, and ozone. “Global temperature has rose approximately 1.4 degrees Fahrenheit over
In talking about global warming, we need to learn what causes the greenhouse effect. Rays from the sun are taken up and absorbed by water vapor that is natural in the atmosphere. The United States emits the largest man made greenhouse gases in the world. As Americans we must realize the responsibility to reduce the emissions. (Gore, Albert) Water Vapor is eighty percent of greenhouse warming. The last twenty percent results from other gases that are in very little amounts. A huge absorber of the sun’s heat rays is carbon dioxide. Us as humans release a lot of carbon dioxide. When fossil fuels are burned, they release big amounts of carbon dioxide. Carbon dioxide is on the increase in our atmosphere due to car emissions. Approximately eighty percent of CO2 increases because of man’s use of fossil fuels. When there is more carbon dioxide in our atmosphere the more sun rays are absorbed. In result to this happening this will cause the earth and the earths atmosphere to warm. When the earth is warming, water temperatures will start to get warmer. Oceans and lakes will get warmer in result f...
Global Warming is a condition caused by greenhouse gases and human activities. The increased concentration of greenhouse gases due to activities such as deforestation and fossil fuel burning is causing the Earth’s atmosphere and oceans to warm up. As a result of this, global warming has some serious effects in the shape of extreme weather, species extinctions, and rising sea levels. These effects can contribute to the changes that are taking place all over the world, most of which are dangerous enough to pose a threat to the survival of life on Earth in the future.
As we approach the future we are faced with many global problems. Most of these problems arise because we have caused them ourselves. We need to face these problems and find a solution. Global warming, although most often overlooked in importance, is a crucial problem of the future directly related to human activities. Global warming is caused by gases humans release into the atmosphere called anthropogenic gases and by deforestation. Anthropogenic gases include carbon dioxide, methane, chlorofluorocarbons (CFCs), hydrofl...
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.
