To be able to fully answer that question first we must understand global warming, what causes it, what the effects are, and how can we change it if it does exist. Global warming is when the earth’s temperature increases, which is caused by greenhouse gasses such as carbon dioxide, water vapor, nitrous oxide, and methane. These gases trap heat and light form the sun in the earth’s atmosphere causing the temperature to rise on earth. Greenhouse gases are necessary for the survival of life on our planet but due to the large increase of average global temperatures people are pointing at human activity for speeding up the process to a degree that is deemed unsafe. Certain events have caused the natural greenhouse gases to rise...

Process of slowing it down 2. Consequences of global climate change Global Warming Global warming is the increase of a surface temperature that traps heat in that needs to escape from the earth, (Global Warming FAQ, n.d.). This is known as a greenhouse effect. The cause of global warming is the carbon dioxide and many other air pollutants that are in the atmosphere collect in the sky to make a thickening blanket (Global Warming, 2005). Some effects are: rising sea levels, salt water intrusion, beach erosion, extreme weather, and increased rainfall, destabilization of local climate, acidic oceans, and drought. Conserving energy is important so the earth won’t get polluted so much. When car buying choosing a hybrid vehicle is the best option, they contain gas electric engines. Carpooling puts less greenhouse gases into the air. Recycling means less trash goes to the dump to be burned. Using fluorescent light bulbs instead of incandescent bulbs save energy. Although they may cost more but they last longer and provide safer air to breathe. Reasons for global warming: * Deforestation ...

...Global Warming An Inconvenient Truth, a bold message that drew all the attention throughout the world about global warming was written and presented by former Vice President Al Gore. In his documentary, Al Gore discusses many global issues as well as the personal relevance they bear in his and all of our lives today and in our futures. The book, as a whole, is a huge success. It also raises public awareness of global climate change and tells the truth that lies behind global warming. It is a very daring book. However, some critiques have been made of Al Gore’s approach. The criticism is not whether global warming is true, or whether or not An Inconvenient Truth should have won an Academy Award for best documentary, but whether Al Gore has presented the information correctly and honestly. Many people argue that he has exaggerated, and he wrote the book because he wanted to gain popularity and money. Conservatives even use Gore’s mistakes to discredit his whole book. Even though Gore has made some mistakes, his central ideas are broadly accurate, and his use of good strategies makes his argument really convincing. Since the book An Inconvenient Truth got published, many people have become nervous, and they attacked Gore personally, such as people from polluting firms and organizations that were funded by polluters. Sean Hannity reports on Fox News channel’s Hannity & Colmes when Gore was running his campaign. He says that Gore’s use of a jet from New Hampshire back to Washington...

...Astronomy 1020 Global Warming The Global Warming dispute has baffled scientists for many years and as the increasing carbon dioxide deposits continue to flood the atmosphere it is now considered one of mankind’s largest challenges in the 21st century. Global warming is climate change that causes the average temperature of the Earth's lower atmosphere to increase. Global warming can have many different causes, but it is most commonly associated with human interference, specifically the release of excessive amounts of greenhouse gases. With this gas buildup, the Earth's atmosphere warms to unnatural temperatures, which causes an increase of natural disasters and causes sea levels to rise amongst other things. This warming trend is sometimes called the greenhouse effect because gases, such as water vapor and carbon dioxide, act like a greenhouse around the earth. Scientist continue to struggle to determine whether or not the global warming and the increase in carbon dioxide emissions is caused by human burning of fossil fuels, farming, and deforestation activities or whether it is a completely natural phenomena caused by the Sun. To understand global warming’s impact on the Earth we must first understand the Sun’s contribution to the warming effects. As supplier of almost all the energy in Earth's environment, the Sun has a strong influence on our climate. According to Dr Sami Solanki, the director of the renowned Max Planck Institute for Solar System Research in Gottingen...

...Global Warming Nowadays the human life is developing continuously in every field like technology, science, education, art, society and so on. Besides that, these developments have generated many negative effects. One of these biggest problems currently is global warming, that the whole world is facing with. According to Theodore C. Sorensen, an American presidential adviser, “Global warming is for real. Every scientist knows that now, and we are on our way to the destruction of every species on earth, if we don't pay attention and reverse our course”. In fact, global warming is happing and humans are causing it. Global warming will largely affect human in the future, so it is worldwide concern. However, none all of us know exactly the definition, the reasons, the impacts of global warming, and the solutions for global warming. What is the global warming? Global warming is a gradual increase in temperature of Earth’s surface, oceans and atmosphere. Scientists have documented and accepted the global warming as fact since 1800s. According to the lasted (January 2014) analysis from NASA’s Goddard Institute for Space Studies (GISS), Earth’s average temperature has risen by 0.8 degrees Celsius (1.4 degrees Fahrenheit) since 1980. Temperatures are predicted to rise another 1.133 to 6.42 degrees Celsius (2 to 11.5 degrees Fahrenheit) over the next 100 years. These statistics of temperature change are based on many independent scientific analyses from observations of the climate system...

Facts and Fiction of Global Warning 1. Facts 2. Fiction II. Conclusion Global Warming: Fact or Fiction According to the New York Times, “Global warming has become perhaps the most complicated issue facing world leaders”. The debate on Global warming’s causes and effects are controversial between scientists and some politicians. Scientists believe that the earth is getting hotter due to the greenhouse effect and some politicians believe that Global warming is the natural phenomenon where the earth’s surface temperature increases due to different factors in the earth’s biosphere naturally. The greenhouse effect is basically heat from the sun being radiated back into the earth’s atmosphere and absorbed by water vapors, carbon dioxide, methane and ozone which comprise greenhouse gases. Greenhouse gases contribute to about 1% of the earth’s atmosphere but they help regulate our climate by trapping heat in the atmosphere and holding it there. The greenhouse effect is really a good thing because it helps sustain life on earth. Without...

...Humans: The Cause of Global Warming Alicia Ferrell Miller-Motte Technical College Humans are responsible for global warming for many reasons and if it is not controlled properly it can affect the future of this planet. The burning of fossil fuels, mass deforestation, and increased population are all causes of global warming. "Global warming is believed to be caused by changes in the earth's atmosphere as a result of industrial process."(Leggett 124) Global warming is the rise of Earth’s temperature causing a vast amount of issues. The sign that supports the human cause is abundant and powerful, some say it is normal for the planet to undergo such changes in atmospheric temperature. If we, as humans, do not change the way we use resources, our planet will be doomed for the future. Deforestation is a major topic in today’s era. Man has cut down trees in great amounts that has led to the obliteration of great forests and the lives of countless animals and plant types. We are unsuccessful at realizing that trees are the most important characteristics of our planet and the presence of tress does play a dynamic role. They provide homes to many, controls the climatic surroundings, and avoids soil in erosions and many more. However, trees have been disappearing at a disturbing rate and it is projected that, about 50 % of the tree cover has been removed. Trees are being cut for numerous purposes and when reforestation is not happening, the proportion between the cut trees and...

...Global Warming Anita Orzel Southern New Hampshire University Global Warming The earth has undergone periodic changes known as global cooling, and global warming. Today’s global warming is unique, due to human influences. American people should be concerned, as the world's scientific experts agree that industrial and land use activities are having an unfavorable impact on global warming. Burning of fossil fuels such as coal, oil, gasoline cause buildup in greenhouse gasses, in addition, deforestation, and destruction of ozone layer create global warming. Earth will suffer serious environmental damage if there are no precautions taken now to reduce global warming pollution. To prevent further damage to global warming caused by human activities, policies must be implemented and diligently enforced, all nations need to partake in action plan to implement policies such as fossil fuel conservation and recycling programs. Greenhouse gases help sustain life on earth by trapping heat from the sun and keeping the earth warm. Some greenhouse gasses develop naturally some occur from human activities. Naturally occurring gasses are, water vapor, carbon dioxide, methane, and nitrous oxide (An Overview of Greenhouse Gases 2009). Human activities, such as, burning of solid waste, fossil fuels such as, oil, natural gas, and coal, wood, raising of livestock, and industrial activities add to the greenhouse gasses, and destroy the ozone layer. Lynas M. (2006) burning fossil fuels release...

...The global warming hypothesis originated in 1896 when Svante Arrhenius, a Swedish chemist, developed the theory that carbon dioxide emissions from the burning of fossil fuels would cause global temperatures to rise by trapping excess heat in the earth’s atmosphere. Arrhenius understood that the earth’s climate is heated by a process known as the greenhouse effect. While close to half the solar radiation reaching the earth’s surface is reflected back into space, the remainder is absorbed by land masses and oceans, warming the earth’s surface and atmosphere. This warming process radiates energy, most of which passes through the atmosphere and back into space. However, small concentrations of greenhouse gases like water vapor and carbon dioxide convert some of this energy to heat and either absorb it or reflect it back to the earth’s surface. These heat-trapping gases work much like a greenhouse: Sunlight passes through, but a certain amount of radiated heat remains trapped. The greenhouse effect plays an essential role in preventing the planet from entering a perpetual ice age: Remove the greenhouse gases from the atmosphere and the earth’s temperature would plummet by around 60 degrees Fahrenheit. However, scientists who have elaborated on Arrhenius’s theory of global warming are concerned that increasing concentrations of greenhouse gases in the atmosphere are causing an unprecedented rise in global temperatures, with potentially harmful consequences for the environment and...

...Global warming and climate change can both refer to the observed century-scale rise in the average temperature of the Earth's climate system and its related effects. Multiple lines of scientific evidence show that the climate system is warming. More than 90% of the additional energy stored in the climate system since 1970 has gone into ocean warming; the remainder has melted ice, and warmed the continents and atmosphere. Many of the observed changes since the 1950s are unprecedented over decades to millennia. Scientific understanding of global warming has been increasing. In its fifth assessment in 2014 the Intergovernmental Panel on Climate Change reported that scientists were more than 95% certain that most of global warming is caused by increasing concentrations of greenhouse gases and other human activities. Climate model projections summarized in AR5 indicated that during the 21st century the global surface temperature is likely to rise a further for their lowest emissions scenario using stringent mitigation and for their highest. These findings have been recognized by the national science academies of the major industrialized nations. Future climate change and associated impacts will be different from region to region around the globe. The effects of an increase in global temperature include a rise in sea levels and a change in the amount and pattern of precipitation, as well as a probable expansion of subtropical deserts. Warming is expected to be strongest in the...

... Global Warming Global warming is a grave issue that is affecting not only the United States, but the whole world as well. Various international strategies need to be implemented so that these issues can be tackled. If taken seriously, the issue of global warming can not only be overcome, it can be prevented as well. Poll conducted in my community- family members, friends, and coworkers- asking if they felt whether or not global warming was a problem or not or undecided: Two examples of how global warming if affecting the life of our communities: * Global warming is already leading to more violent storms and less predictable weather patterns. According to the Pew Center on Global Warming, since 1995, only two years have not had above average hurricane activity. The overall number of tropical storms has not increased, but there are more storms strong enough to be called hurricanes. We will probably continue to get bigger storms, which will do more damage to coastal areas. * Global warming will have drastic effects on local ecosystems. Most plants and animals are adapted for a certain environment. Generally, each species does well when the temperature is in a certain range, and the seasons work in a regular way. As things like temperature and seasonal precipitation shift, less robust plants and animals are not going to be able to adapt quickly enough. This will result in widespread extinction. Three facts that are relevant to global warming: * Arctic...

...Global Warming Did Humans start it and can it be stopped? SCI 207 Stacy Murphy October 8, 2012 Global Warming: Did humans start it and can it be stopped? Humans have used planet Earth and its resources like they had no end. But for the few years they have started coming to realization that Earth and the people on it cannot survive for much longer, if they don’t change the way they are living. Now that it has come to this, they are trying to strategize and come up with ways to try and save the planet. Can we do it or have we already gone too far past no return? Earth is in a stage called global warming. Global warming is the rise in the average temperature of the Earth’s atmosphere and oceans. Since the late 19th century, scientists have been warning the world that due to the increase of greenhouse gases in the Earth’s atmosphere, it is causes the Earth to undergo changes that are not good for humans or the planet. Some these increases are being caused by human activities such as burning of fossil fuels and deforestation. The Earth’s temperature had increased 0.8 degrees Celsius over the past 100 years and with about 0.6 degrees of this warming in the past three decades (National Research Council 2011). The effects of this increase in temperature cause the sea levels to raise, changes in the amount and pattern of precipitation, as well as an expansion in the subtropical deserts. Warming is expected to be the strongest in the Arctic from the continuing break in the...

...they will attempt to give attribution to the warming, which now looks more and more like a natural cycle. See updates below. – Anthony ================================================================ Guest essay by Bob Tisdale The recently published climate model-based paper Recent global-warming hiatus tied to equatorial Pacific surface cooling [Paywalled] by Yu Kosaka and Shang-Ping Xie has gained a lot of attention around the blogosphere. Like Meehl et al (2012) and Meehl et al (2013), Kosaka and Xie blame the warming stoppage on the recent domination of La Niña events. The last two sentences of Kosaka and Xie (2013) read: Our results show that the current hiatus is part of natural climate variability, tied specifically to a La-Niña-like decadal cooling. Although similar decadal hiatus events may occur in the future, the multi-decadal warming trend is very likely to continue with greenhouse gas increase. Anyone with a little common sense who’s reading the abstract and the hype around the blogosphere and the Meehl et al papers will logically now be asking: if La Niña events can stop global warming, then how much do El Niño events contribute? 50%? The climate science community is actually hurting itself when they fail to answer the obvious questions. And what about the Atlantic Multidecadal Oscillation (AMO)? What happens to global surface temperatures when the AMO also peaks and no longer contributes to the warming? The climate science community skirts the...

...Global Warming Global warming has become perhaps the most complicated issue facing human beans and world leaders today . Warnings from the scientific community are becoming louder, as an increasing body of science points to rising dangers from the ongoing buildup of human-related greenhouse gases — produced mainly by the burning of fossil fuels and forests. Global warming is when the temperature of the earth rises which causes the earth to heat up. This effect happens because of greenhouse gases carbon dioxide ,water vapors, nitrous oxide and methane .These gases trap heat and light from the sun in the earths atmosphere which therefore increases the temperature of the earth. This is a negative impact on the earth and it effects humans ,animals, plants, and climates. A major theory to what causes global warming is the greenhouse effect . The greenhouse effect is when heat and light is trapped in earths atmosphere as a result of this happening the temperature rises. The greenhouse effect has a positive and a negative side on the positive side the greenhouse effect makes earth adaptable for people to live on, without it the earth would be freezing, or on the other hand it would be very hot. Although the greenhouse effect makes it able for humans to function and live on this earth if there gets to be to many gases the earth can get warmer and plants,animals,and humans might die. The reason why humans would die because there would be less food,corn,wheat, vegetables and fruits...
