KeynoteSpeaker_Abstract
U. Houston, ABSTRACTS 2006
Excerpt: ... Why Carbon Sequestration and the Technologies related to it? Out of the roughly 30 Gt of anthropogenic carbon dioxide emissions into the atmosphere, about 25 Gt are due to the consumption and flaring of fossil fuels. Several studies have demonstrated a direct link between the accumulation of green house gases in the atmosphere, and a surface global warming of about 0.60.2C. Given the expected growth in the energy demand, and the resulting gradual shift to coal to bridge the supply gap, a more pronounced carbon dioxide emission is likely in the next few decades. To mitigate some of the undesirable consequences in climate change as forecasted by the IPCC, carbon sequestration seems to be the most viable option for the medium term. With the vast experience dealing with hydrocarbon reservoirs and fluid injection, we argue that the oil and gas industry appears to be the best suited to provide the most viable solutions for reducing atmospheric accumulations of greenhouse gases. As estimated by the EPA and others ...

nuclear power
TCNJ, ENG 155
Excerpt: ... sil fuels. According to a study done by MIT and Harvard, fossil-fuel based electricity is expected to account for more than 40% of global greenhouse gas emissions by 2020. Currently in the US, 90% of carbon emissions from electricity come from coal, even though this accounts for only 52% of electricity produced. Taking nuclear power off the table as a reasonable alternative will prevent its global use in controlling carbon dioxide emissions . However, nuclear power is not perfect. There are high relative costs and possible safety, environmental, and health hazards if it is not well-managed. There are also unresolved challenges in long-term management of nuclear wastes. But there are many ways to lessen these costs, and over time, the price of carbon emissions could work in nuclear power's favor. Overall, those scared by the world "nuclear" should not write off the use of this energy source. Nuclear power may be the most efficient way to curb carbon dioxide emissions and stop that pesky global warming from dest ...

ECCD, GEOG 2101
Excerpt: ... - is less than the current daily temperature range for most major cities, and thus hardly a cause for concern. Warming cannot be due to greenhouse gases since changes in temperature and changes in greenhouse gas emissions over the past century did not occur simultaneously. 16 15 Carbon dioxide is removed from the air fairly quickly, so we can wait to take action to reduce greenhouse gas emissions until after we see the impacts of warming. Human activities contribute only a small fraction of carbon dioxide emissions , an amount too small to have a significant effect on climate, particularly since the oceans absorb most of the extra carbon dioxide emissions . The Earth has warmed rapidly in the past without dire consequences, so society and ecosystems can adapt readily to any foreseeable warming. 17 The buildup of carbon dioxide will lead to a "greening" of the Earth because plants can utilize the extra carbon dioxide to speed their growth. It is hard enough to predict the weather a few ...

Field Notes from a Catastrophe Summary
IUP, ENGL 101
Excerpt: ... Field Notes from a Catastrophe Summary Sarah Angiolelli The beginning of the book kind of introduces the idea of global warming to the general public. They know that most people are not familiar with the complex ideas that go along with such a general idea so they do a good job of explaining it. They speak of the Carbon dioxide emissions and how the United States is such a great producer of the harmful chemical. In addition, the other country's governments are taking serious measures to cut down on the harmful emissions of Carbon dioxide and our government is not. The woman decides to take a trip to Alaska to investigate her assumptions further and another doctor accompanies her. They take the trip in a truck which they spend hours driving in but when they finally get there they think it is worth it. follow the pipeline and see how the permafrost is melting. There are some communities which are built entirely on permafrost. Their whole towns are being ruined and they are They being driven out o ...

Assignment #4_Letter_Problem_Set_Solution
Cornell, CHEM 106
Excerpt: ... Maurice D. Hinchey New York-22nd, Democrat 2431 Rayburn HOB Washington, DC 20515-3222 Dear Congressman Hinchey: We are students at Cornell University studying chemistry and its applications to everyday life. Recently, we focused on global warming and its effects on our lives and on our future. Furthermore, we have researched and learned that there was a bill introduced in the Senate to reduce greenhouse gas emissions in the United States by establishing a market-driven system of greenhouse gas trade-able allowances. This bill, S. 280, also supports the use of new technologies that help to alter climate. We believe that global warming is a serious problem that the government cannot ignore. The United States is currently the worldwide leader in per capita carbon dioxide emissions and is also first in total emissions. By limiting the amount of emissions produced in each state, the United States can take great strides towards curbing this tremendous problem. In a New York Times article, Robert N. Stavins, directo ...

Excerpt: ... s well as other resources. As the consumption of energy sources continues to increase, so does the demand for the source. Therefore, the increasing economy this is demanding more energy sources for consumption is the driving force behind increased carbon dioxide emissions . In response to these increasing emissions is the warming of our atmosphere. Over the last 10-20 years, the United States has experienced recordbreaking years of warmth. This increased the demand for another electrical device, air conditioning, fans, and other cooling devices powered by energy consumption. This limited hydroelectric power and increased the release of carbon dioxide output from coal-fired plants and gas release. Also, we can not forget about the inefficiency of energy conversion for consumer use. It has been reported that typical power plants convert only 1/3 of the energy consumed towards electricity, while the remaining energy is released into the atmosphere as HEAT. These thermal inefficiencies are releasing large numbers ...

Excerpt: ... dioxide concentrations, the construct of business-as-usual (BAU) is often utilized. BAU assumes that people will continue behaving just as they have been. In other words, their transportation behaviors, consumption patterns, etc. will continue along the current trajectory. Under BAU conditions, studies show that we are likely to roughly double our carbon dioxide emissions over the next 50 years. In order to meet the 500 ppm goal, however, greenhouse gas emission rates must remain approximately the same as they are today. An often-cited article published in 2004 by Pacala and Socolow argue that we have the ability with current technology to stay under the 500 ppm concentration goal over the next 50 years. We currently produce 7 Gigatons of carbon (GtC) emissions annually, but we are on track to over double that value to more than 14 GtC/y by 2050. To meet the 500 ppm level, we need to keep emissions constant at about 7 GtC annually. Pacala and Socolow use the idea of the climate stabilization triangle divided ...

Excerpt: ... erns of native people and native species in the Arctic have shifted drastically over the past half-century. Warming on the scale projected by this study could well mean the extinction of some species of seals and polar bears, and a certain end to traditional ways of life. These are sobering thoughts. Ice cores show that over history the polar climate has fluctuated, often severely. But this fluctuation is caused by human activity. Even if we were to sharply and immediately reduce carbon dioxide emissions , some arctic warming would continue. The solution to this problem rests on our ability to imagine and purposefully shape the future. One obvious way is to create international agreements and recognize that immediate restraint on our part may make the difference. The Bush administration has denied the severity of global warming and the science behind it. On this vital matter, the president needs to look a painful reality squarely in the face.

Excerpt: ... tc.). The instructor may want to review the class results and note the top three-five contributors of carbon dioxide emissions (i.e., car use, airplane use, utility use). Once the top three-five class contributors of carbon dioxide emissions are identified, students should develop proposals of realistic methods/steps that students in the class can take to reduce their carbon dioxide emissions . Students should focus on novel ideas that may not have been developed yet. Further, students should research the background of the Kyoto Protocol and develop an argument as to whether or not the U.S. should ratify the protocol. Groups should present their proposals and arguments regarding the Kyoto Protocol in a five-minute presentation to the entire class. ...

Excerpt: ... China to Pass U.S. in 2009 In Emissions - New York Times http:/select.nytimes.com/search/restricted/article?res=F50B12F83A5B. November 7, 2006 China to Pass U.S. in 2009 In Emissions By KEITH BRADSHER; JAD MOUAWAD CONTRIBUTED REPORTING FROM NEW YORK. China will surpass the United States in 2009, nearly a decade ahead of previous predictions, as the biggest emitter of the main gas linked to global warming, the International Energy Agency has concluded in a report to be released Tuesday. China's rise, fueled heavily by coal, is particularly troubling to climate scientists because as a developing country, China is exempt from the Kyoto Protocol's requirements for reductions in emissions of global warming gases. Unregulated emissions from China, India and other developing countries are likely to account for most of the global increase in carbon dioxide emissions over the next quarter-century. The agency's prediction highlights the unexpected speed with which China is emerging as the biggest contributor to ...

Syracuse, PPA 777
Excerpt: ... n in 2006 was 100 quadrillion Btu, or 21% of the worlds total. Per capita energy consumption was 335 million Btu. The strong economic performance of the United States during the 1990s helped to increase energy usage. Of total energy consumption, 40% came from oil, 23% from natural gas, and 22% from coal. Although most electricity currently is generated in coal plants (52%, compared to 21% nuclear and 16% of natural gas), most new electric power plants use natural gas. However, production of electricity from natural gas fell slightly in recent years, due to higher natural gas prices. Carbon dioxide emissions : Total carbon dioxide emissions in 2005 were 5.9 billion metric tons. This is 20% of the global total. Even on a per capita basis, the U.S. figure of 19.8 metric tons per person is much higher than other developed countries. In the Kyoto Protocol, the United States pledged to reduce carbon emissions 7% from 1990 levels by 2008-2012. Since then, total emissions have increased, and President George W. Bus ...

In 2002, Vermont produced 37% of the national supply of syrup. Maple trees need warm days and cold nights for the sap to flow, and warmer springs will shorten the sugaring season and decrease syrup production. WHAT IS RGGI and HOW DOES IT WORK? The Regional Greenhouse Gas Initiative (RGGI) is a seven-state program introduced in 2005 to reduce carbon dioxide emissions from power plants while maintaining affordable energy prices and reliability for the consumer. Emissions will be controlled by a cap and trade system, which places a limit on the overall carbon dioxide emissions for the region and for individual states. Companies will only be granted a certain number of emissions permits, or permits to pollute, and will not be allowed to pollute more than their quota all ...

Excerpt: ... January 18, 2007 Bills on Climate Move to Spotlight in New Congress By FELICITY BARRINGER and ANDREW C. REVKIN WASHINGTON, Jan. 17 - The climate here has definitely changed. Legislation to control global warming that once had a passionate but quixotic ring to it is now serious business. Congressional Democrats are increasingly determined to wrest control of the issue from the White House and impose the mandatory controls on carbon dioxide emissions that most smokestack industries have long opposed. Four major Democratic bills have been announced, with more expected. One of these measures, or a blend of them, stands an excellent chance of passage in this Congress or the next, industry and environmental lobbyists said in interviews. Many events have combined to create the new direction - forsythia blooming in lawmakers' gardens in January, polar bears lacking the ice they need to hunt and Al Gore's movie, "An Inconvenient Truth," along with pragmatic executives seeking an idea of future costs and, especially ...

Excerpt: ... e of the top 25 spots in the worldwide rankings are occupied by countries in economic distress, including Uganda, Chad and Myanmar. Switzerland, Costa Rica and Peru are the exceptions. The study's definition of renewable energy resources does not include nuclear power - in part, Mr. Esty said, because countries with a high proportion of nuclear-fueled energy, like Japan, the Czech Republic and France, reaped the benefits of their energy choices by earning high rankings on the study's other scales, like the air quality index measuring particulate matter. To create another scale that disproportionately favored nuclear-energy users would have undermined the overall reliability of the study, he said. As a result, the renewable-energy rankings tilt heavily toward countries reliant on hydropower, like tiny Bhutan. The study shows that annual carbon dioxide emissions , measured as metric tons per $1 million of gross domestic product, average about 363 tons. North Korea, Turkmenistan, Ukraine, Uzbekistan and Mongolia ...
