There has been an ongoing debate about whether global warming is man-made, natural or if it even exists at all. The answer to that debate is that global warming is man-made and a direct result of pollution. Carbon Dioxide, methane and nitrous oxide make up the biggest part of the cause of global warming, which form greenhouse gases Some people believe that global warming is caused by natural components in the environment and not man-made production of carbon dioxide, while the others believe that it is caused by man-made production of carbon dioxide and not by natural components in the environment. Global warming is due to the increased level in temperature of The debate on global warming and global climate change has been going on for several decades. One group is of the opinion that man in the name of technological progress has actually caused damage to the environment and was the reason of the global climate change. The other group believes that global change is a phenomenon that has been in progress for thousands of years and that it is nothing new

Climate change is defined in the change in global climatic patterns since the midth century and is not limited to simply warming temperatures, is global warming man made essay, but also extends to irregular precipitation, freak natural disaster events, record-breaking freeze spells, and much more.
The message of the film asserts that humans are causing global warming and that the effects can already be seen and will continue to devastate Volgren, However, there is an important place for looking carefully at the numbers and discerning fact from fiction. Perhaps the most talked about evidence of climate change is that of rising concentration levels of carbon dioxide. Carbon dioxide is a gas made from the combination of oxygen from the air with carbon deriving the man-made activities of from the burning of coal or oil, or from natural processes found in the carbon cycle.
Some sceptics defend their case saying that carbon is natural and a part of life! And although this is true, we must consider that if carbon dioxide CO2 had no harmful effects, then carbon emissions would not matter. However, the catch here is that carbon dioxide is a greenhouse gas and although it is not the strongest nor most prevalent in our atmosphere, it is significant nonetheless.
The main effects of putting more of it in the atmosphere include the absorption of infrared radiation heat which impedes the natural flow of heat from the planet and has a warming effect. The human activities that drive the burning of fossil fuels driving, urbanization, food production, powering machinery that produces more fossil fuel, etc undeniably have the effect of releasing carbon dioxide in the atmosphere.
It is important to recognize all of the forms of greenhouse gases, but carbon dioxide is the gas most frequently researched and discussed by scientists. As shown in Figure 1, the rate of carbon dioxide concentration used to be steady; a flat plateau from the s to the s. Figure 1: Carbon dioxide concentrations over the last years in parts per million. This data was measured from two sources: air trapped in ice cores which show varying concentrations of carbon dioxide up to and directly in Hawaii from onwards.
In the yeara noticeable shift occurred and the amounts of carbon dioxide began to increase rapidly at an exponential rate. In fact, the year marks the start of the Industrial Revolution, when James Watt patented the steam engine and is the beginning of unprecedented amounts of coal being burned from making iron and ships, heating buildings, powering vehicles and other machinery, and of course, powering the pumps that enabled more and more coal to be mine inside of hills all over Europe Mackay, 5.
Therefore, this shows that the correlation between higher amounts of carbon dioxidation is by no means an accident nor was it a part of a natural process from the preceding thousands of years. Although the facts speak for themselves, many politicians and members of the public are still skeptical that increased levels of carbon dioxide are caused by anthropogenic activities.
David MacKay dispels this myth effectively in the following argument. Yet the biosphere and the oceans send about 1, gigatons and 36, gigatons of Co2 per year into the atmosphere - one reason why some of us are sceptical about the emphasis put on the role of human fuel-burning in the greenhouse gas effect. The argument posed is appealing. However, MacKay demonstrates its misconceptions using scientific data.
MacKay points out that all three numbers used by Lawson seven, 1, and 36, are wrong and that they should be 26,andrespectively MacKay, 9. It is scientifically correct that natural flows of CO2 ie: outputs from the biosphere and ocean are larger than the additional concentrations that have spiked since years ago, as shown in Figure 1. However, it is misleading to quantify and show only the large natural input of carbon dioxide into the atmosphere without talking about how almost exactly the same amount is global warming man made essay out of the atmosphere back into these natural sinks ie: the biosphere and ocean.
Just a simple elementary schooler could tell you that earth systems work in cycles; for example, nitrogen and water cycles through the earth, the atmosphere, the ocean, and back to earth.
This simple law of nature applies to the cycling of carbon as well, and is not accounted for in charts, such as shown in Figure 1, because these large natural flows, cancel themselves out. Therefore, it is not relevant that these natural flows are greater than human emissions and sceptics such as Lawson have no argument. This phenomena is closely related to increasing amounts of carbon dioxide as previously discussed as well as other greenhouse gases, which act as a thermal blanket for the Earth, to support life at an average of temperature of 59 degrees Fahrenheit 15 degrees Celsius.
Changes to this average temperature will have serious consequences for all life on Earth as we know it Jenkins NASA. An important aspect of the greenhouse gas is that it is true that when atmospheric concentrations of greenhouse gases increasingly become trapped in the troposphere, the average temperature of the lower atmosphere, which affects human life, will also gradually increase.
Climate scientists, physicists, university researchers, world leaders and so many more, have found the evidence and continue to do research on the nature of climate change and how humans are affecting it. So far, the factors of fossil fuel burning, increasing levels of carbon dioxide, and the greenhouse gas have been discussed; by what changes are scientists now witnessing and will these worsen?
According to Amber Jenkins from NASA, although it is difficult to predict the consequences of changing the natural atmospheric greenhouse condition, the following effects are agreed upon by scientists to be likely. On average, is global warming man made essay, surface temperatures on Earth seem to be getting warmer, as evidence shows that the so-called average global temperature has increased 1 by 0. This increase is slightly more severe in the northern hemisphere than southern, with rapid glacier melting occurring in places such as Alaska, Greenland, the Himalaya, the Arctic ice shelf and other mountainous regions; however, is global warming man made essay, Antarctica is less affected, contrary to popular belief Dittmar and Nicollerat, Furthermore, increasing global temperatures results in shorter and warmer winter seasons in many areas of the world.
These warmer conditions lead to more evaporation and overall precipitation levels; however, individual regions vary as some become wetter ex: flooding in United Kingdom while others become drier ex: Southwestern United States. These factors have a is global warming man made essay toll on humanity considering that water and weather our necessary for our agricultural food systems, is global warming man made essay.
Although some crops and plants may respond positively to increased levels of atmospheric carbon dioxide, many more will suffer from soil failure and water shortage.
These effects outlined are just a short beginning to the complex, interrelated web of climate change consequences. Beyond drought and uncertain weather events, there are several other ways that humanity will be affected by climate change.
Our air and is global warming man made essay of water will continue to be polluted and dirty due to the increase is atmospheric ozone due to climate change. This has tolls on human health as we may see more cases of allergies and asthma will continue to rise, especially in urban areas such as New York City, as well as longer pollen seasons which will result in more air-based allergies. Sea-level rise is also a major concern for city-dwellers and other coastal communities.
Cities are more susceptible to natural disasters wrought by climate change increased hurricanes, more severe storms, flooding, etc and many cities do not have climate-change ready emergency plans.
Thus, city life could become far more dangerous than suburban areas, is global warming man made essay. A big question in moving forward, is how can national governments as well as individuals do their part in stopping or slowing down climate change. Individuals can do their part every day, on a small scale from biking instead of driving cars, and on a big scale through community organizing to make large, systematic changes to reduce climate change.
Cooperation is a key part of making is global warming man made essay planet a more liveable, healthier place in the future. Human activities undoubtedly have a role in climate change. Those who wish to dismiss this statement are in denial of a truth that is inconvenient, yet unavoidable. Dittmar, Michael, and Anne-Sylvie Nicollerat. Dutt, V. Freeman, Jody, and Andrew Guzman.
