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. Global warming, or climate change, is the increase in the earth’s surface, ocean, and atmospheric temperature over time due to pollutants that are stuck in the ozone layer of the earth. These pollutants such as carbon dioxide and chlorofluorocarbons trap radiation from the sun that would normally escape the earth’s atmosphere. This phenomenon is known as the green house effect, and has caused global temperature to dangerously increase over the past decades. If global temperature continues to …show more content…
When fossil fuels are burned carbon dioxide and other heat trapping greenhouse gasses are released into the ozone layer. Humans obtain the energy to heat our homes, run our vehicles, power manufacturing, and generate electricity from oil, coal, and natural gas, which are all fossil fuels. Scientists are able to relate the dangerous carbon dioxide in the atmosphere to these fossil fuels due to the carbon dioxide’s unique finger print. Another reason for these harmful gases in the atmosphere is deforestation. Deforestation causes large amounts of carbon dioxide to be released into the atmosphere when trees are cut down. These trees that are cut down would normally help absorb the extra carbon dioxide, but now they are unavailable to play their role. The rapid increase in the amount of greenhouse gases in the atmosphere is causing the temperature of the earth to rise at a rate that many living things cannot adapt
“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.
Recent scientific evidence indicates that humans have upset the carbon cycle, leaving more carbon dioxide and other greenhouse gases in the atmosphere. Burning fossil fuels such as oil and natural gas, burning biomass such as ethanol and wood, creating cement and releasing other chemicals into the atmosphere is upsetting the natural flow of carbon.
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
Global warming is an issue we are all pretty familiar with. It is the climate change that we, humans, are responsible for. The warming of the earth’s atmosphere is caused by the fossil fuels we burn, clearing of forests, and the carbon dioxide and other harmful gases we release into the air (Cunningham, Cunningham, 2009). There are other harmful toxins we use such as pesticides that are supporting global warming. Some effects of global warming include: increase in weather catastrophes, melting glaciers, rising sea levels, and the impact on species could lead to extinction (Cunningham, Cunningham, 2009). “Many scientists regard anthropogenic global climate change to be the most i...
According to the United States Environmental Protection Agency (EPA), carbon dioxide is the primary gas emitted through human activities and is the most important human contributed greenhouse gas (Overview of greenhouse, 2014). Carbon dioxide is naturally occurring in Earth’s atmosphere. The passing of carbon dioxide through the atmosphere, oceans, soil, plants, and animals is what is known as the carbon cycle. This carbon cycle is important to sustaining life here on Earth. Carbon dioxide is important to life on earth because it is the main component of many biological compounds, minerals, and exists in various forms in the atmosphere (Carbon Cycle, 2014). Humans are disrupting this carbon cycle however by adding more carbon dioxide to the atmosphere and by removing natural absorbers of carbon dioxide, like forests to remove the carbon dioxide from the atmosphere. This is where the greenhouse effect comes into play, since the industrial revolution there has been an increase in the human-related emission of carbon dioxide mainly due to the burning or combustion of fossil fuels for energy. Other contributors include certain industrial processes, the differen...
One of the biggest environmental impacts which is steadily increasing in severity due to fossil fuel usage is global warming. Global warming is mainly caused due to the trapping of heat in the atmosphere due to increased amounts of carbon dioxide. Because of the burning of fossil fuels, there has been a twenty five percent increase in the amount of carbon dioxide in the atmosphere over the last 150 years (Clean Energy). This increase over the years has caused the global average surface temperature to raise ...
Before a person can tackle handling the concept of global warming, they first must analyze the true definition of what it is. Climate change periodic modification of Earth’s climate brought about as a result of changes in the atmosphere as well as interactions between the atmosphere and various other geologic, chemical, biological, and geographic factors within the Earth 's system. (britannica) Since all 196 countries in the world have to share the oxygen and carbon dioxide, we all should take a part in the responsibility of taking care of earth. On November 6, 2012 President Obama said that we want our children to live in a world without the destructive power of a warming planet. The biggest challenge we face is not only saving a warming
The Earth’s current CO2 level is at 393.84ppm (CO2now, 2013). This is the highest of the high levels in the past 450,000 years. Extra carbon dioxide in the air is believed to keep temperatures steady and contributing to the greenhouse effect which causes the planet to warm. Scientists believe that humans add CO2 through the burning of fossil fuels, deforestation, and livestock farming to name a few. Natural processes also contribute to the CO2 emitted into the atmosphere including forest fires. Two sources on Earth remove CO2 from the atmosphere: Trees and the ocean. Deforestation can contribute to global warming because trees absorb carbon dioxide and when trees are removed the Earth loses its natural carbon storehouses. Phytoplankton consume CO2 through the photosynthesis process and transport it from the ocean’ surface to the deep. These sources eliminate 30-50% of carbon dioxide in the atmosphere.
The most destructive human contribution to climate change is fossil fuels combustion, which results in the release of carbon dioxide and other greenhouse gases into the atmosphere. Increased carbon dioxide, methane, nitrous oxide and halocarbons levels in the atmosphere cause an imbalance in the earth’s energy. This is because the gases alter solar radiation and thermal radiation which regulate the earth’s energy. Research indicates that anthropogenic climate change is the cause of the increased global warming over the last fifty years. 57 % of the carbon dioxide emitted is absorbed into the atmosphere while the rest is absorbed into the oceans. Carbon dioxide in the atmosphere is the most central greenhouse gas that is associated with global warming (Eby, Zickfield, Montenegro, Archer, Meissner, & Weaver,
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...
The burning of fossil fuels has greatly harmed our environment and is a leading cause as to why climate change has become such a threat to our way of living. In May of 2013, the carbon dioxide levels in the atmosphere reached 400 parts per million, an increase of more than 40 percent since the beginning of the Industrial Revolution. This could cause the Arctic Ocean to be nearly ice-free during the summer by 2020(Overland and Wang, 2013).
Humans and animals breathe out Carbon Dioxide, often referred to as the greenhouse gas, as a waste product. Plants take in this CO2 and use it to make food. This is called photosynthesis. During this process oxygen is released which is then breathed in by humans and animals. This procedure is repeated over and over and a natural balance is obtained. However this natural balance is disrupted by human activity. People of the world are putting more than 5.5 billion tons of CO2 into the atmosphere every year. 75% of this is caused from the burning of fossil fuels. These fuels are burnt all the time to run factories, power plants and vehicles. The main sources of CO2 emissions are electric utilities, residential buildings, industry and transportation. The other 25% is induced by the destruction of the world's forests. The reason for this is that there are less trees and plants to take in the CO2 but there is just as many, if not more, humans and animals to breathe it out.
The commonly debated “greenhouse effect” refers to “the global-average temperature increase that has been observed over the last one hundred years or more” (Spencer). President Barack Obama addressed the issue as an effort to highlight its severity, "We have to all shoulder the responsibility for keeping the planet habitable, or we’re going to suffer the consequences – together” (Leader). The earth’s increasing atmospheric and oceanic temperatures result in climate changes due to cumulative amounts of carbon dioxide (CO2) in the atmosphere.
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.
The earth is a complex system, which continues to evolve and change. Climate change and global warming are currently popular in the political agenda. But what does “climate” really mean? The difference between weather and climate can be conveyed in a single sentence: “Climate is what you expect; weather is what you get.” Based on research of the geologic record, we know that climate change has happened throughout Earth's history and at present, ever-increasing evidence points to the roles that humans play in altering Earth systems. The Earth and its atmosphere receive heat energy from the sun; the atmospheric heat budget of the Earth depends on the balance between incoming solar radiation and outgoing radiation from the planet; which has been constant over the last few thousand years. However present evidence seems to suggest that the recent increase in temperature has been brought about by pollution of the atmosphere, in particular the release of huge amounts of carbon dioxide, mostly through Anthropogenic Forcing (human activity) and other various internal and external factors.
