June 11, 2014 Abstract Global warming has been a topic of much debate, heated arguments and even the creation of environment oriented groups that look to impact the modern industrial world with their views and protest driven rallies in an effort to spread awareness about climate change. Cause and Mitigation Climate change has certainly been a bigger topic of discussion now than it has ever been in the past 10 years. While "some people speculate that the current global warming trend is part of

Global warming: The beginning of Armageddon My Artefact (1) / My Newspaper article (1) Scientists, celebrities, and everyday people have been trying to understand the nature of global warming. Controversy is rampant and there is intense debate around the world on the subject. The most obvious thing that can be said about global warming is that the earth is getting warmer. Specifically, the temperatures near the surface of the earth and the temperatures in the ocean are rising. Since 1990

Global Warming Mitigation Strategies and Solutions David Zavala University of Phoenix/Axia College Our atmosphere took billions of years to develop into what we know today but technological advances have given today’s society the power to change the atmosphere in less than a century. The revolution that began in the late eighteenth century made it possible for inventors to create many energy-saving machines. The only energy these machines save is human energy and time because these machines

over periods ranging from decades to millions of years. The world is currently experiencing drastic change in temperature. This change can be felt in the tropical climate areas where the weather is getting hotter and hotter every day. The change in global temperatures and precipitation over time is due to natural variability or to human activity. It is also caused by accumulation of greenhouse effects (Arrhenius, 1896). Should we as humans let this problem worsen? Climate change will affect everything

Clean Air Act – Help to breathe or not? Abstract When you first awake and take in the first long breath and exhale to start the day, do you think about that air being clean? This was not a question until 1948 where the industrial town of Donora, Pennsylvania had a thick cloud of air pollution formed over the town. (EPA, 2015) The event started the public awareness on the effects of air pollution and how it causes health problems. Clean Air Act – Help to breathe or not? Introduction

Closing case Chapter 6 Why did global food prices rise? Summary: In the last 25 years global food prices have been going downwards. This is thanks to the increasing productivity and output of the farm sector worldwide. However in 2007 prices went up dramatically. We can say that one of the main reasons was the increased demand in food. One of the main drivers has been the consumption of food in rapidly developing nations China and India. Rising consumption in meat leads to more demand in

The average pH of ocean surface waters has already fallen by about 0.1 units, from about 8.2 to 8.1 since the beginning of the Industrial Revolution. Estimates of projected future atmospheric and oceanic CO2 concentrations indicate that, by the end of this century, the average surface ocean pH could be 0.2 to 0.4 lower than it is today (IPCC 2014). The two main influences on sea level rise are the melting of land ice of glaciers and the ice cap on greenland and the change in density as result of

Paper Class of 2010 May 29, 2009 Global Warming The most important problem that concerns for many people all over the world is global warming. Global warming is defined as the increase of the average temperature on Earth. As the Earth is getting hotter, disasters like hurricanes, droughts and floods are getting more frequent (by Karin Lindinger). Every problem has its own causes. Scientists have determined that a number of human activities are contributing to global warming by adding excessive amount

Name: Date: Instructor’s Name: Assignment: SCIE211 Phase 3 Lab Report Title: Sources of CO2 Emissions Purpose The purpose of this lab is to research and state reasons for the trend of carbon dioxide emissions from data provided by the Earth System Research Laboratory over the past 40 years. Introduction Fossil fuels, wood, and living organisms are only some of the things that carbon is found in. The Earth uses CO2 to sustain life using the Carbon Cycle. Plants use the carbon for photosynthesis

by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions. Certain human activities have also been identified as significant causes of recent climate change, often referred to as "global warming". Scientists actively work to understand past and future climate by using observations and theoretical models. A climate record — extending deep into the Earth's past — has been assembled, and continues to be built up, based on geological
