Global warming is a phenomenon caused and intensified by humans as we have exploited the earth heavily for its resources and in doing so we have caused a large change in the characteristics of our planet and its climate.
Global warming is caused foremost through the release of green house gases (GHGs) mostly through the burning of fossil fuels, the trend can be very clealry seen between CO2 levels and temperature increase over the last 150 years. The last 150 years have bshown such a huge change in CO2 levels because of the expansion and birth of heavy industry across the globe which requires fossil fuels to be burnt, this releases green house gases into the atmosphere, a higher than normal concentration of green house gases in the atmosphere means traps heat in the atmosphere of the earth as they act as an instulator
GHG’s
Industrial revolution/ industrialisation
Increasing population (higher demand for goods)
Transport expansion (wide spread use of cars, large amount of air travel)
Fossil fuel burning
CFC’s
Ozone depletion

BANGLADESH AS EXAMPLE OF EFFECTS
Temps increases
Sea level rising
Sea surface temps rising (Increasing scale and severity of monsoons and TRS’s)
Saltation intrusion (Bangladesh up to 100km in causing issues with the agricultural industry, rice paddies around the coast line as well as fish and plant life which are commonly susceptible to specific salt/fresh water compositions)
More intense extremes of temp and weather -zero rain dry monsoon in future
Ice and snow melting from the higher temperatures
Drought and flooding occurring more frequently
Difficultly in maintaining a safe sustainable source of clean fresh

...of everything produced from oil (fertilizer, food, and fuel) rise beyond what some people can afford to pay. Energy and economic problems come at a time of unprecedented environmental concerns, from the local to global level. At the beginning of the modern era—in A.D. 1—the number of people in the world was probably about 100 million, one-third of the present population of the United States. In 1960 the world contained 3 billion people. Our population has more than doubled in the last 40 years, to 6.8 billion people today. In the United States, population increase is often apparent when we travel. Urban traffic snarls, long lines to enter national parks, and difficulty getting tickets to popular attractions are all symptoms of a growing population. If recent human population growth rates continue, our numbers could reach 9.4 billion by 2050. The problem is that the Earth has not grown any larger, and the abundance of its resources has not increased—in many cases, quite the opposite. How, then, can Earth sustain all these people? And what is the maximum number of people that could live on Earth, not just for a short time but sustained over a long period? Estimates of how many people the planet can support range from 2.5 billion to 40 billion (a population not possible with today's technology). Why do the estimates vary so widely? Because the answer depends on what quality of life people are willing to accept. Beyond a threshold world population of about 4–6 billion, the quality...

March. http://thehill.com/blogs/congress-blog/labor/218525-faa-why-we-should-invest-today-in-airports-inc) With the latest Federal Aviation Administration (FAA) forecast predicting a doubling of passengers and cargo by 2030, the current funding system is not up to the job of ensuring airports will have the infrastructure they need to handle such dramatic increases in traffic. This will have far-reaching consequences. Commercial airports are powerful economic engines, generating 10.5 million jobs and $1.2 trillion for the U.S. economy, according to a new Airports Council International-North America study. Across the country, workers and businesses count on local airports to attract investment and move people and goods around the world. Since 2001, the total number of jobs associated with airports has increased by more than 50 percent. Despite unprecedented growth and clear evidence of the economic benefits of infrastructure investments, airports expect to have $80 billion in unmet needs through 2015 because of the flawed system...

...INTRODUCTION TO MACROECONOMICS E202 $ ¥ Dr. David A. Dilts Department of Economics Doermer School of Business and Management Sciences Indiana-Purdue University-Fort Wayne June 1, 1993 Revisions: May 1994, December 1995, July 1996, November, 2000, May 2003, May 2006 PREFACE This Course Guide was developed in part because of the high cost of college textbooks, and in part, to help organize students’ studying by providing lecture notes together with the reading assignments. This Guide is provided to the student online at the Department of Economics website. Jayla Heller, the Department’s secretary has been kind enough to go through all of the frustration and hard work to put the guide in the appropriate format and put it online. To her goes my gratitude. The department, neither school, nor the professor make anything whatsoever from this Guide. In fact, the department’s budget and the professor’s own resources are used in the writing of the Guide, and the numerous draft copies that are produced in the revisions of this document. Like the sign in the Mom and Pop bait shop on Big Barbee Lake says, “This is a non-profit organization, wasn’t planned to be – it just worked out that way.” Well, actually it was planned to be a non-profit enterprise in this case. The professor also wishes to acknowledge the fact that several students have proposed changes, improvements, caught errors, and helped to make this document more useful as a learning tool. Naturally, any errors of omission...

The end of the Cold War is usually seen as the beginning of the contemporary era in world politics which is the subject matter of this book. It is, therefore, appropriate that we begin the story with a discussion of the Cold War. The chapter shows how the dominance of two superpowers, the United States of America and the Soviet Union, was central to the Cold War. It tracks the various arenas of the Cold War in different parts of the world. The chapter views the NonAligned Movement (NAM) as a challenge to the dominance of the two superpowers and describes the attempts by the non-aligned countries to establish a New International Economic Order (NIEO) as a means of attaining economic development and political independence. It concludes with an assessment of India’s role in NAM and asks how successful the policy of nonalignment has been in protecting India’s interests. The end of the Second...

Our goal is to provide leaders in the commercial, public, and social sectors with the facts and insights on which to base management and policy decisions. MGI research combines the disciplines of economics and management, employing the analytical tools of economics with the insights of business leaders. Our “micro-to-macro” methodology examines microeconomic industry trends to better understand the broad macroeconomic forces affecting business strategy and public policy. MGI’s in-depth reports have covered more than 20 countries and 30 industries. Current research focuses on four themes: productivity and growth, the evolution of global financial markets, the economic impact of technology and innovation, and urbanization. Recent reports have assessed job creation, resource productivity, cities of the future, and the impact of the Internet. MGI is led by McKinsey & Company directors Richard Dobbs and James Manyika. Yougang Chen, Michael Chui, Susan Lund, and Jaana Remes serve as MGI principals. Project teams are led by a group of senior fellows and include consultants from McKinsey’s offices around the world. These teams draw...
