In environmentalist Bill McKibben’s 2008 article, “Civilization Last Chance,” we are warned that we are in a state of emergency time we have little to save our environment from the danger. The current status of our earth is in danger, and people don’t seem to realize the serious consequence for the future. Robert W. Christopherson’s textbook, Geosystems, is an introduction to physical geography with scientific evidence. The current edition of Geosystems introduces the consensus science regarding human-created climate change. The high content of carbon causes global warming and global warming causes climate change.
Global Warming: Changing the Climate Control Policies For the past 10 years, 2000 until today, we have experienced some phenomenal natural disasters. For example, the 2004 Indonesia tsunamis, 2010 Haiti earthquakes, 2010 Icelandic volcano eruption, and massive hurricanes in the Atlantic, and they are leaving everyone wondering, why? Even though these are natural disasters and it seems there is nothing we can do to avoid these catastrophes; we can help control the climate around us. Climatologists have been warning the government all around the world of the possible effects due to global warming and there is still no agreement on the action that needs to be taken. Since we have the attention of everyone, now is the best time to take action against global warming.
Effects of Global Warming on Walruses When people talk about global warming, they think of the polar ice caps being melted and humans causing too much pollution in the air from various activities. It is actually an overall increase in the average temperature of the Earth’s surface caused by gases being trapped in the atmosphere by the “greenhouse effect” . From the North down to the South Pole temperatures are rising and the world is heating up fast. This has caused many changes in the nature of things. One such victim of the change in our climate is a pinniped most commonly known as the walrus.
[Intro.] He stresses the urgency of this problem, a repeated number of times, and challenges the audience to raise awareness throughout the entire film. [Emotion] Gore uses a clip from the series Futurama, to add some humor to the documentary, to help describe to greenhouse effect. He posts a rhetorical question to his audience asking: "You wouldn't want to make a cute, fluffy, polar bear drown now would you? [Logic] Gore discusses the possibility of the collapse of a major ice sheets in Greenland and in West Antarctica, which could raise global sea levels by 20 feet and flood coastal areas.
Which factors contribute to global climate change and how do these factors impact the earth compared to anthropogenic carbon dioxide emissions? Bodden, Zachary Environmental Systems and Societies Strawberry Crest High School May, 2014 3563 Abstract The most popular theory for the cause of global warming today is the burning of fossil fuels. Furthermore, there has been much speculation that anthropogenic carbon dioxide emission will have a harmful impact on the earth. However, through research, it shows that this truly is, only a speculation. In this paper, I plan to analyze the underlying causes of climate change, and the consequences the earth faces.
Since the temperatures have started to rise, the ice that they once lived on has melted and they are having a very difficult time surviving. People have increased the temperature of the Earth by contributing their pollution. Burning fossil fuels and forests has been the biggest issue amongst us all. Simple changes could help in simple ways but the fact is that since it is a global issue, the world has to be involved in order to make a difference. The United Nations has contributed in this way by holding meetings to discuss the climate changes throughout the world and what can be done to help.
Clearly life and climate interact with each other (McCaffrey). If life had never appeared on the earth’s surface, the local climates would have been different from those which have prevailed. And if climate had everywhere been unchanging throughout geologic time, the varied life we know- the millions of species- might not have come about. These are just a few of the many headlines that crossed the wires in last few years: “Europe’s summers to get hotter,” “The Arctic’s ominous thaw,” “Study shows warming trend in Alaskan Streams,” “Global Warming Seen as Security Threat,” “Global warming a bigger threat to poor,” “Tibet’s glacier’s heading for meltdown,” “USA: Climate change is costing millions.” Global warming has achieved the status of a major threat. It inspires nightmares of a troubled future and propels apocalyptic drams such as the summer 2004 movie “The Day After Tomorrow.” The twentieth century was the warmest of the past 1000 years and 19 of the 20 hottest years on record occurred after 1980 (Climate Change Facts).
The Extinction of the Polar Bear What Greenhouse gases are, how they work, and why they are threatening the very existence of the polar bear. “If a warming world melts nearly all sea ice during summers, as computer models predict will happen by the end of the century, scientists warn that the polar bear is unlikely to survive as a species.” Jordan Sherry 05-30-06 The Problem Carbon dioxide is what’s know as a “greenhouse gas” meaning it is able to keep the Earth warm by trapping some of the heat it produces within the Earth’s atmosphere. But if too much of the gas is trapped in the atmosphere it can get too hot, and according to scientists that is what is happening now. Starting during Industrial Revolution to concentration of carbon dioxide has increased by nearly 35 percent, which is more than the Earth has experienced in more than 650,000 years and more than the natural variability would allow. This in turn has cause the average temperature over the past century to raise about 1 degree, and another 4 degree increase is expected during the 21st century.
Another geological record, the cycling of ice age/inter glacial periods, suggest that the earth is approaching the end of the present interglacial, the Holocene. I think, though, that you wish to know whether or not human activity is a major driver in climate change? Human influence, sometimes called Anthropogenic Global Warming (AGW), more recently just Climate Change, has been a hotly debated topic over the last three decades, with proponents for and against arguing shrilly about AGW theory. It is best to avoid the most shrill arguments and concentrate on known facts. 1.
I strongly agree that people should give up their cars to save the earth. First of, according to Environmental Protection of United Kingdom, statistic proved that cars account for 22% emission of carbon dioxide which is the major contributor to climate change. World’s climate has been fluctuating throughout this decade and it arise the concern of many. Ices in North Pole are partially melted due to the drastic increase in temperature. This does not only affect the habitats living in North Pole but causing sea level to rise on top of this.
