It is not the job of politicians to sort the fact and opinion about global warming. On one hand McCarthy, 2012, says we pollute the air with greenhouse gases from fossil fuels and methane, emitting from the landfills that we stuff with trash that is on average 4. Global warming causes extreme temperatures, which affect quality of life and could be unbearable to people and other living organisms in highly affected. There are too many unknowns just to be jumping the gun.
While animals also breathe out carbon dioxide and methane, their small contribution is miniscule compared to humans and their consumption of non-renewable energy. As more and more fossil fuels are burned the atmosphere layer will get thicker and thicker. Human presence on this earth can either make or break the natural world. Methane is produced from the processing of oil, landfills and released from the digestive systems of livestock. Like any controversial topic, there are two main opinions with the majority claiming that the climate change is mainly man-made, if not entirely human-caused. Words: 1663 - Pages: 7.
Over that time, more than 250 Australians have joined David Wren on what, for many, is the trip of a lifetime. My sciences agree that there are natural causes to climate change so says the sun greenhouse effect and reflectivity. Theses scientists also fear that human activity will have long consequential problems for the world. Since it is trapped it warms the earth, keeping a constant temperature to accomodate life's needs. We are cutting down the trees that naturally take in our waste product so it will not aid in diminishing us as a race and the world as we know it and even supplies us with oxygen in return, but at least we have all the paper we. Carbon dioxide, as well as other greenhouse gases, is a very important factor in the vital cycles which sustain life on this planet: plants use carbon dioxide in photosynthesis and release oxygen necessary to maintain the lives of animal species, who through breathing out return carbon dioxide into the atmosphere, completing the cycle Taylor.
These create a deadly environment for the fish. Words: 2339 - Pages: 10. Green House Effect was first considered into study by S. Climate change is the fluctuation in weather and temperature on Earth either in a specific part of the world, or even the entire world itself. Natural temperature rises may be explained by the climate variability, yet they usually happen gradually, hence allowing other components of the eco-system adjust and accommodate to the new conditions. Global warming is a global event while climate change is a more regional change in the atmosphere. The fact is that earth left the natural path a long time ago.
Works Cited Intergovernmental Panel on Climate Change. Temperatures have been skyrocketing and scientists have no other explanation other than to say that human activity is the main cause of climate change to this point. Some theorize that global warming might lead to melting snow caps, which will result in sea levels rise in all the oceans. These are the greenhouse gases and, in order of importance, water vapor, carbon dioxide, methane and nitrous oxide. Other natural causes are the changes in solar activity, volcanic eruptions, natural forest fires, etc. There is no doubt it is one of the biggest environmental issues throughout time, though it is widely debated among scientists and environmentalists what the main causes are.
Many gases are sent into the air when are burnt of which main is the carbon dioxide gas. More demand for cars means more and more traffic on the roads which means longer waiting time on the traffic lights and that will result in burning of more fuel. Despite not signing the treaty, emissions in the United States have dropped 9 percent in the period of two years fr0m 2007 to 2009. Words: 2963 - Pages: 12. Those related to natural processes and those related to human activity.
Global warming is the very hot topic now because of being high risk environmental issue. Energy use is largely driven by economic growth with short-term fluctuations in its growth rate created by weather patterns affecting heating and cooling needs. Although it may be difficult for politicians and business people to believe are to take advantage of the information. Name: Instructor: Curse: Date: Is Climate Change Natural or Man-made? At that time many scientists said that climate was more likely to be part of a cycle of warming and cooling which happened every 1500 years they said. The National Academy of Science has studied climate change and confirmed that it is real and humans are causing it.
Fossil fuel like coal is burnt to produce electricity. For many years it was hard to tell in what direction the climate was headed. The believers think the increased temperatures of the earth prove that global warming exists as the main problem and it should be taken seriously. For the purpose of this essay it is assumed that global warming results from human production of excess green house gases including carbon dioxide emissions Gore, 2006. Many people have been affected by global warming, for example hurricanes are cause by the warm water from the seas. They thought it was due to a natural 1,500 year cycle.
The daily mail in 2007 — many experts said that global warming was a natural cycle. Scientists have provided solid evidence of global climate change by humans in multiple studies, but others believe that climate change is caused… 1544 Words 7 Pages Global warming has become a well conversed topic among scientists and peoples in the world today. Local transport is at a premium throughout the week and our added value service avoids any long waits. Melting permafrost in the North and South Poles at high level also contributes to the global warming. Higher concentrations of greenhouse gases present in our atmosphere improves the heat-trapping ability of our earth. Dating back to millions of years ago, even before humanity was born, the world has always experienced one form or another of warming; so the warming seen today is not as bizarre as many may… 1539 Words 7 Pages of global climate over long periods of time.
