Different Arguments and Theories on Global Warming and Why to Take Action Every year, almost 7 billion tons of carbon dioxide is released into the atmosphere by human activity. That is the equivalent of 107,700,000 jet airplanes being in the air at once! This harrowing figure is the main cause of global warming, and has been increasing for the last 50 years. Global warming is caused by the increase of greenhouse gasses, carbon dioxide and methane primarily, in the earth's upper atmosphere directly caused by human burning of fossil fuels, industrial, farming, and deforestation activities. Global warming is defined as an increase in the average temperature of the earth's atmosphere (especially a sustained increase that causes climatic changes). Many people believe in these statements, but there are many people around the world that refuse to believe that human contributions are the main cause of global warming, saying that the increase is part of the natural climatic change of earth. Debatable causes and solutions of this theory of global warming include the natural climatic change, the grounds of human causes, and the solutions we can take to halt global warming. As humans, we all have our own opinions, but the problem of global warming should not be debated; it should be solved. Many people around the world debate about the facts about global warming. The evidence that supports the human cause is plentiful and powerful, but few can find support for the issue that global warming is a natural part of the Earth's climatic change. Some people do support this issue, like John Christy, director of the Earth System Science Center at the University of Alabama in Huntsville. Christy says, "The carbon dioxide from fossil fuels is di... ... middle of paper ... ...witching to these more efficient types of energy, the amount of carbon dioxide released into the atmosphere would be drastically decreased. As a nation, we are attributed as the leading cause of global warming, with the most greenhouse emissions anywhere in the world. In addition, as the most influential country in the world, we can choose to sit by and watch it happen, or we can decide to become a more environmentally aware population, setting an example for the entire world to see. The debate of the causes of global warming should not matter, because the fact is that we are contributing to global warming through our activities, adding on to any natural climatic phase that the earth is experiencing. By not releasing so much greenhouse gasses into the atmosphere, we can end the global warming scare, and end the most debated environmental topic of the world today.
Global warming is a big problem for us, and there are things that we have done to cause it.
“All across the world, in every kind of environment and region known to man, increasingly dangerous weather patterns and devastating storms are abruptly putting an end to the long-running debate over whether or not climate change is real. Not only is it real, it's here, and its effects are giving rise to a frighteningly new global phenomenon: the man-made natural disaster.” BARACK OBAMA, speech, Apr. 3, 2006. Climate change is not a theory contrary to what many individuals believe and is in fact confirmed by major scientific agencies such as the National Oceanic and Atmospheric Administration (NOAA) and the National Aeronautics and Space Administration (NASA) in the United States. Global Warming causes are mainly due to greenhouse gases that are trapped in the atmosphere and cause depletion of the earth’s ozone layer. Carbon Dioxide is a greenhouse gas, and although it is a necessary component in our atmosphere as it helps plants perform photosynthesis, too much of it causes ozone depletion and therefore climate change. Carbon Dioxide levels in the atmosphere have increased tremendously after the industrial revolution, which indicates that the major cause of this issue is due to anthropogenic activities.
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...
Most climate scientists agree that the main cause of global climate change is the human expansion of the greenhouse effect. This is the global warming that results when the atmosphere traps heat radiating from Earth toward space (climate.nasa.gov). The main gases that contribute to the greenhouse effect include water vapor, carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons (climate.nasa.gov). Human activities are changing the natural greenhouse effect. The burning of fossil fuels like coal and oil has increased the amount of carbon dioxide in the atmosphere (climate.nasa.gov). Carbon dioxide levels have increased from 280 parts per million to 379 parts per million in the last 150 years due to human act...
Global climate change is a phenomenon widely accepted by the public in today’s society. A survey from Yale revealed that 63% of Americans believe that global warming is currently happening (Leiserowitz, 2013). And although the public has shown to misunderstand the scientific field, in the case of climate change, science supports their beliefs. Now, a majority of scientists accept that extreme changes are occurring in the world. Evidence is showing that worldwide climate change is real, and the consequences will cause adverse effects to all forms of life.
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 is an increasing threat to the Earth and future generations. Global warming, sometimes called climate change, is the name given to the process of heat getting trapped in the atmosphere and damaging the environment. Greenhouse gases cause heat to gets stuck in the atmosphere by trapping the sun’s rays. When the sun’s rays enter the Earth, they should bounce back into the atmosphere. Instead the gases trap them, causing the temperature to rise. In the past the temperature of the Earth has risen slowly and evenly but recently the temperature has risen faster. The temperature of the Earth has risen at least one degree Fahrenheit during the twentieth century. If global warming is not controlled there are serious consequences. People, animals, and plants could be living in an atmosphere that is not suitable for sustaining healthy lives.
The emission of green house gasses due to human activity contributes the most in increasing global warming. Today, fossil fuels are used as a source of energy for transportation, electricity, industrial process and to increase human comfort in this era. Over the last decade humans have created mass amount of industries. These industries have been burning fossil fuels such as coal, which release carbon dioxide and carbon monoxide; carbon dioxide absorbs heat that raises the temperature of the earth. More than 80% of carbon dioxide comes from tr...
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
The concept of global warming has become one of the most widely debated and controversial topics of our time. Scientists learned long ago that the earth’s climate has powerfully shaped the history of humanity. However, it is only in the past few decades that research has revealed that humans have a significant influence on the climate as well. A growing body of scientific evidence indicates that since 1950, the world’s climate has been warming, primarily as a result of emissions from the burning of fossil fuels and the destruction of tropical forests. More importantly, an article titled "Global Warming" published in the New York Times shows that methane, a gas that is emitted from landfills, livestock and oil gas facilities, is a close second to the carbon dioxide impact on the atmosphere (“Global Warming”). Though there are many scientists who support and can prove that global warming really does exist, a team of scientists from Competitive Enterprise Institute (CEI) spend their time and energy disproving the myths behind global warming.
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...
There are many pros and cons about global warming. “Overwhelming Scientific consensus says human activity is primarily responsible for global climate change”(“Is Human Activity Primarily Responsible for Global Climate Change?”). They say that the human activity causing global warming. A pro would be “Rising levels of human-produced gases released into the atmosphere create a green house effect that traps heat and causes global warming”(“Is Human Activity Primarily Responsible for Global Climate Change?”). The gases that we release are carbon dioxide, methane, and nitrous oxide. These gases build a shield that keeps the warmth inside Earth. Us humans help produce the Co2 that is emitted into the air. “As of 2008, only 39 out of every 100,000 molecules of air were CO2, and it will take mankind’s CO2 emissions 5 more years to increase that number by 1, to 40”(“Global Warming”). The reason we blame it on mother nature is because we can’t technically determine the sensitivity of the climate yet. I understand where we are causing the bad of global warming. We want to have a regular summer, not too hot. We want a normal winter where it actually snows. “Climate change- happens with or without our help”(“Global Warming”).
Hello everyone! Today I will be speaking about global warming but before I begin, how many of you believe that global warming exists and that the human population is the primary cause of global warming? I ask this because there are people who believe that global warming does not exist or that it’s “a hoax created by China”. But that’s not true and global warming is in fact one of the biggest problems facing the world today. There is a significant amount of negative effects for the environment and for all living beings due to global warming. And maybe some of you are not be interested in global warming, but the truth is, global warming is a big part of our world and it affects each and every one of us.
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...
The controversial subject of global warming according to a large amount of scientists is not a prominent concern. 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 ...
