Dire Predictions: Global Warming

Geography November 29, 2010 fearful Predictions Student Edition Chapter superstar of Dire Predictions Understanding spherical warm up does exactly like the title says, it gives the reviewer the inhering basics of understanding the Global Warming issue. Chapter one gives essential information regaleing a wide range of things including the pictorial and merciful impacts on climate, definition of a glasshouse gas and how it alludes temperature, positive and nix feedback loops, threatening human byproducts that affect the ozone, bureaus scientists study ancient climates, and it gives potential future Earth outcomes due to globular heating.It is a really ludicrous chapter I hit the sack, alone this information proves to be very valuable when gibeedness about world(prenominal) warming. In fact, the information is so valuable that it substructuret be covered by righteous stating a warm overview of the chapter, but needs a to a greater extent detailed summary. Some na tural variables that potentially affect the Earths climate include the sun, volfannyic eruptions, and Earths orbit. But how exactly does roundthing like a vol whoremasteric eruption effect climate?This is because Explosive volcanic eruptions modify the firearm of the atmosphere by injecting small particles called aerosols into the atmosphere layer. These released aerosols block the solar shaft of clean that would put on r distributivelyed Earths surface and consequently, it has cooling effect on Earths surface. The more than talked about topic in chapter one however is the non-natural, or human induced impacts causing global warming. man burning of fossil fuels and release of chlorofluoro coulombs (CFCs) are both founts of human variables that affect global warming.CFCs are a kind of gas that is released by cooling apparatus such as the refrigerator. These gasses acquit been proven to obliterate the ozone. Furthermore, the book goes on to prove that the major impacts caus ing global warming are not natural but aboutly human do. It states that the tar in the ozone is not mostly caused by a natural accession in CO2 gasses but the release of CFC-11 and CFC-12 gasses by humans into the environs. As proof of the gasses affect on the ozone it states that the average temperature of the globe has gone up from 13. degrees Celsius to 14. 5 degrees Celsius. It canvasms like a small amount of temperature increase but even one degree average increase can wee a major influence on global warming. Finally, chapter one goes on to describe what discovers if these patterns persist. So what leave behind happen if these patterns persist, and what do will it have on agriculture and man? To better understand what will happen to us, we have to understand what the ozone layer does. The ozone layer protects us from libellous ultraviolet shaft.If these patterns persist the ozone will protect little and little ultraviolet radioactivity from entering Earths atmo sphere. If this happens then the sorbet caps will vanish which will be catastrophic to man and agriculture. According to http//www. tropical-rainforest-animals. com/Global-Warming-Effects. html some effects of global warming will be Floods Droughts, Heat waves, innate winter cold and hoodwink fall, Tornadoes, Extreme storms, Tropical cyclones, hurricanes, and typhoons. You dont have to be a geography major to know that these types of effects will deal a devastating blow to people and plants.Precipitation patterns will also change everywhere, messing up normal agricultural growth. Some more effects global warming will have on agriculture and animals is it will drag trees produce leaves earlier, it will cause earlier color on vegetation, it causes re-distributions of algae that will kill animals that eat it to survive, and the ultraviolet radiation will ultimately poison humans and animals and destroy plants everywhere. If we have no ozone life will be unsustainable on Earth. Bu t wait, all these stately things dont have to happen we can do things to go along global warming.We can start to friend this not to happen by burning up less fossil fuels, thus reducing emissions into the ozone. Scientists and mechanics have recently been working together to make cars that produce less waste and are better for the environment. We can help by purchasing these kinds of cars and investing in this type of research. An separate route to help is if we as a world unite and we set goals and laws that require fewer emissions from each country. Also, it may seem small but a way we can all help is by recycling things which cuts down the waste it takes to make whole new things.More ways you can help are by using less air conditioning and heat, ever-changing light bulbs to more energy in force(p) ones, buying energy efficient products, driving less or carpooling, using less hot water, and finally set a tree. Although planting a tree or changing a light bulb may seem like a small way to help, if everyone in the world followed these suggestions emissions would be greatly abridged which could save the Earth. Scientists have worked together to try to understand the problem.By constantly recording new entropy and looking at old data they have come to a better understanding of what we use that causes these emissions and the way it affects us and our planet. A way scientists have studied the ancient atmosphere is by drilling into the ice caps and examining the trapped air. Also scientists are constantly observing the ozone layer to see any changes that might come. Scientists also look at what kind of molecules the ozone is make of and gasses that could destroy it. Learning about the problem is half the battle so we are on our way to a brighter tomorrow.I think the information given over in the book was good information based on scientific truths. The information in this book was very easy to follow as almost every page had a corresponding graph or get wind to help you understand the information given. However one of the problems I had with the information in this book is I felt that it was really ardent to discredit the other(a) side of the argument with not much detail. When approach with an opposing point the author just basically says that all other views are wrong and moves on.Also, the information in this book jumped to something completely different every other page. But that being said I did learn a lot from reading this book. The thing I make up most enkindle in the book were some of the statistics given throughout the chapter. For example thought how long the gasses CFC-11 and CFC-12 last and how much more potent it is that vitamin C dioxide. Even after five hundred old age after CFC-12 is released, it is hushed 5,200 times more potent than carbon dioxide. And five hundred years after CFC-11 is released, it is 1,620 times more potent that the carbon dioxide (Dire Predictions, p. 9). With CFC gasses and other ha rmful gasses lasting this long it is important to stop the release of these harmful gasses as soon as we can. Another thing I found interesting in the book was the change in Mount Kilimanjaro snow coverage over time. First, it shows Mount Kilimanjaro during the year 1912 and it is covered in snow. That picture is followed by a picture of Mount Kilimanjaro during the year 2007, and the snow cover has almost all disappeared. Another statistic I found very interesting in chapter one is the graphs on page thirty-three.These graphs show the amount of carbon dioxide, methane, and nitrous oxide in the atmosphere before and up to 2005. The graphs show that the levels of these greenhouse gasses are pretty constant until it reaches the year 2005 When the graph line representing the gasses reaches to just before the year 2005, levels of all three of these gasses skyrocket. (Dire Predictions, pg. 33) Reading this book made me realize how serious the global warming issue is and how it is already alter the world today. Due to global warming life as we know it could possibly come to an end.But dont start putting your bucket list together just yet. If we start doing things everyday to help reduce the emission of greenhouse gasses we can make sure that tomorrow is a brighter day, figuratively that is. The things stated earlier (using less air conditioning and heat, changing light bulbs to more energy efficient ones, buying energy efficient products, driving less or carpooling, using less hot water, planting trees) are all examples of everyday things we can do to help the environment and stop global warming.Another thing that people can do to help this problem is by educating themselves about global warming. By educating yourself about global warming you can solve the problem easier because you know the causes. Also you can educate other people about the importance of taking global warming into consideration. If everyone around the world pitches in to try to help, maybe the succeeding(prenominal) book we read will be Optimistic Predictions.Works Cited Banerjee, Subhankar.
