Overview.

Global warming is become a major issue in our society. Some believe another ice-age will result from global warming, and others believe our earth's nature, and environment will be destroyed beyond repair. Global warming is the idea, of our earth's temperature increasing more and more every year while our polar ice caps melt, and natural habitats get destroyed. Most importantly global warming has many different viewpoints.

Global warming has been a nationwide issue. A heatwave in June 1988, James E. Hansen Director of Space Studies at NASA shows global warming as a result of greenhouse gases and that gas emissions are changing earth's climate. The first report on climate change was in June 2000. The report was called, "Climate Change in American." It stated global warming causes disappearing Alpine meadows, coastal wetlands, barrier islands, and a rise in diseases. Earth's temperature started out as a rise of 1 degree and has rose to 4 degrees in the last century. One solution is described to be, Reduction and Adaption. The question isn't where the climate will change, it's how much, how fast and where it changes. As long as there's humans, CO2 will be released into the atmosphere. Thomas J Crowley, a geologist at Texas A and M University found that "Natural variability plays only a subsidiary role... Most rise is due to the anthropogenic increase in greenhouse gases. Mary L. Walker believes Nuclear power is a solution to global warming. It's cleaner and more smog reducing than oil. She also believes we have to turn to non fossil energies such as, solar, wind, hydro power, geothermal, biomass, and nuclear. If climate change does not change then, sea level will rise 15-95 centimeters by 2100.

Global warming occurs when the sun's energy enters our atmosphere in the form of UV rays and heats our earth surface. With the help of our earths ozone some of the heat remains within our atmosphere. The remaining UV rays are then reflected back into space (Gore, 21). This is a natural process that is needed to heat our earth. The problem we are now encountering that is causing global warming, is the increase in greenhouse gas emissions. As we release more greenhouse gases into our atmosphere such as CO2 emissions and methane gases, we increase the thickness of our ozone layer (25). Now when the heat waves are being reflected into space, more heat waves remain in our atmosphere than ever before because our ozone layer is too thick for the waves to travel through (21). This process is similar to how a greenhouse works.

Greenhouse gases are fueling global warming. Many argue that global warming is just a natural cycle, but there is no way of denying that our increase in greenhouse gas production is harming our environment. 60% of the methane gas located in our atmosphere is produced by humans through livestock, landfills, the burning of fossil fuels, and more (Gore, 51). The most common gas we have produced as humans is CO2. In 1958 our atmosphere had 280 parts per million CO2. In 2005 our atmosphere had 381 parts per million CO2 (36). The reason why this matters to our planet and society is because the slight increases of our worlds temperature is causing massive glaciers to melt, and sea levels to rise.

2005 was the hottest day our nation has seen since the Civil War, not to mention all the cities setting records for high temperatures. The Northern Hemisphere is now hotter than it has ever been in the past 1000 years (Gore, 64). Also in the summer of 2003 Europe was hit by a massive heat wave that killed roughly 35,000 people (74). Some of our worlds most vital glaciers have melted or have already disappeared. Glaciers such as Boulder Glacier, Upsala Glacier, Adamello Glacier, and many more important glaciers are gone (51). The Himalayan Glaciers and the Tibetan Plateau contain 100 times the amount of ice found in the Alps, and within 50 years, all of that ice is expected to melt due to global warming. The reason why this is important to our society, is that those two glaciers provide drinking water for up to 40% of our world's population (58). The melting of the glaciers is also causing a ripple effect because glaciers reflect 80% of UV rays ( "Polar Regions Climate Change", 1). Now that the glaciers are disappearing more UV rays are absorbed by our earth and causing global warming to excel. Another issue is the glaciers, especially the ice caps, which are home to many animals that are now dying more than ever (Mathias, 1).

Glaciers melting is a large issue on it's own, but it is also causing sea level rising. Our ocean is said to now rise 1mm to 2mm every year due to glaciers melting (Mathias,1). Costal areas such as Florida and New York City, will be submerged in water (Gore, 204). Sea level rising will not only affect our world geographically. Many animals and living organism depend on the water, and it's temperature which will rise if the glaciers melt. Coral reefs will begin to die as they will not receive enough sunlight through the deeper water. Fish who need the cold water temperatures to survive will begin to die off, killing other species such as the birds that eat them to die off (Mathias, 2).

Through many studies it is clear to most that we are abusing our world, at a rate that may be irrecoverable. With new technology, we have the option to either help our climate dramatically or destroy it (Gore, 268). A common example of us using our technology to destroy our climate is, irrigation. Today we see massive irrigation systems that divert entire rivers to water crops. The Areal Sea is now virtually empty from the Soviet Union using it for irrigation (Gore, 245). That's why our world, and more specifically our nation, needs to halt the destruction of our environment. The United States has more carbon emissions than any other country, and nearly twice the amount of carbon emissions as Europe (261).

There is still a constant debate about whether global warming is actually occurring, but still 97% of climate experts believe in global warming and climate change (Arguments From Global Warming, 1). Of the 3% that don't they argue, that our climate has gone through changes like this before, for example an ice age. Science responds by saying that human activity is increasing the speed in which it will occur though (1). Another popular argument found among skeptics is that plants and animals can adapt to a warmer climate. Science says other wise and that life can't adapt on such a short time scale (1). The list of skeptics theories continues with "We're headed into an ice age," "There is no consensus," and "Climate sensitivity is low."

In conclusion, the debate over global warming will never end. There is strong evidence showing that global warming is occurring. But, there are also many who doubt the idea of global warming. Global warming is becoming a major political issue, and our society is beginning to form around concepts like alternative energy and saving natural habitats and wildlife. As explained in many articles and papers, change must come as we only have one world. An easy way to grasp the one world idea, is relating it to the Pixar film Wall-E, in which humans are forced to live in space after they take advantage of our worlds delicate environment. Whether you grasp the idea through a movie, or a research paper, it's important that you and our world is aware.


There is Evidence that proves Global warming is real and it is happening. This website basically states that climate change happens and in the last 650,000 years there have been seven cycles of glacial retreat. The last ice age was about 7,000 years ago, which marked the beginning of the modern climate change. It is still unsure if humans are causing global warming or if it is a natural occurrence. The evidence that proves this is the sea level rising (which has rose 6.7 inches in the past century), warming of oceans (the water traps the heat), shrinking ice sheets (NASA's Gravity Recovery and Climate Experiment show that between 2002 and 2006, Greenland lost 150 to 250 cubic kilometers of ice per year, while Antarctica lost about 152 cubic kilometers of ice between 2002 and 2005), Declining sea ice, and ocean acidification.

• Many argue that rising global temperatures are due to human consumption and emission of carbon dioxide.
• With ice caps melting, and the possibility of changing weather patterns and rising water levels, governments around the world seek to agree upon and solve the perceived problem through the adjustment of consumption.
• Others believe caps on emissions and forced changes will create economic disasters.

Gore, Al. An Inconvenient Truth. Rodale. Emmaus PA. 2006. Print.
Summary: An Inconvenient Truth is a non-fiction text, that speaks of global warming, it's effects on our world, and how we can stop it. The book starts off with a great introduction that explains global warming well with the use of statistics and good graphics. The book speaks a lot about, glaciers and their effect on our world as they continue to melt. The book also goes in depth into global warming and its affect on wildlife and future predictions for our world if we continue at this rate.
Assess:The information in this book is very detailed and easy to comprehend. The book covers just the major points mainly using statistics and then supports its assertions with using pictures and graphs. The book is also well organized in a way that is easy to follow. The only disadvantage of the book is the yellow sections that have some of Al Gore's experiences and their connections to global warming. I usually skip over them as they are tedious to read, and don't usually have great information just opinions. I do feel like the book does have a little bit of a political agenda though.
Reflect: This source is great for statistics to help enhance your Wikispace, and to add interesting facts. The book is also good for major points that you can look into online for more details.

Reflections and Conclusions

There is so many different opinions and theories on Global Warming and lots of information that backs up both. Either way, it is a huge problem going on in our society and people don't seem to take it as serious as it really is. I've learned a lot about the effects of climate change. Also, i learned about all the different ways humans can changes their habits to help lower the CO2 that is released into the air. What i found really interesting was that there are satellites that orbit the earth that observes the atmosphere, ice, oceans, and vegetation. I've realized we have so much information on climate change, we just need to act upon it. In my opinion, after reading opinions and such, i still believe Global Warming is a natural occurrence.

I have heard many different opinions about climate change and global warming. From one of the books I read there were two different view points on global warming. Some people thought that it was effecting our climate and that it was a problem and others thought that it wasn't hurting our environment and that we didn't have to worry about it as much as we are. Do you guys think that global warming is the main issue in climate change and it's something we need to worry about?

After spending over 2 weeks researching climate change and global warming, I am very convinced that it is a major issue in our society and that it needs to be addressed. Through this assignment I was able to go more in depth to the science aspects of global warming along with the political and global impact. I learned most importantly the ripple effect of global warming. How it begins with human activity, then leads to effects such as glaciers melting, then sea level rising and final destruction of our environment. Reflecting on the actual idea and purpose of the project, I believe it's a great way to do group work, but experience independence at the same time. The concept of also being able to add videos, images, and hyperlinks also helps to produce a better and more useful paper in today's society.

Throughout this whole research process, I have learned that the climate is alwasy changing. And Global Warming is a serious topic with many different opinions. Some believe that Global Warming will end our world, while some think it is a huge myth. Some believe the earth is heating, others belive it is cooling. There are no real answers or proven information that show whether Global Warming is real or not. It depends on your opinion. I do belive that Global Warming is real, and it is serious. After research, I have learned that Global Warming is caused by humans releasing green house gases into the atmosphere which are heating the earth and warming our earth.
