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 the natural cycle"(Hilderman, 2011, para. 1), there is no denying that the human carbon footprint has had its effect in recent years. The Sun initiates global warming through its natural cycle of orbital variations, these variations are due to the Milankovitch Cycles and the presence of sunspots during these cycles. This initial global warming effect triggers the release of the greenhouse gases into the atmosphere. The Earth has a natural greenhouse effect which means that when carbon dioxide and methane are released into the atmosphere these gases absorb radiation heat from the Sun and keep the average surface temperature on Earth higher, around 14°C, by amplifying the orbital warming. "Without the natural greenhouse effect, the Earth’s average surface temperature would be around -19°C'("Causes", n.d., para. 2). The natural climate cycle is nothing more than the combination of orbital changes and the natural release of greenhouse gases, this process has been occurring for millions of years long before the existence of humans. The scientific consensus is that humans are responsible for the increased global temperature over the last century since the industrial revolution. The amount of greenhouse gases released into the atmosphere due to human activity has over whelmed the natural cycle…...

...Weather Radio Distribution and Education Project On July 2nd of 1997, severe storms and tornadoes tore through Wayne County Michigan. Throughout the course of the storm 90 people were injured and there was a damage cost of $90 million. Based on the repercussion of this storm alone, the county felt a mitigation system was needed to help protect its 2 million residents. To help reduce the effects of storms the county chose to start a weather radio distribution and education project in 1998. This weather radio mitigation project installed national oceanic and atmospheric administration weather radios in every school, hospital, and nursing care facility in the county. This totaled 860 radios throughout these facilities. Included in the mitigation process was an education/training program. Employees of these facilities learned how to plan and prepare for severe weather. This day of education/training was video taped to share with other county facilities and to be used as a state wide example. Also, the mitigation process was funded by the HMGP and the local community. The total cost of installing radios and the education/training day was $21,000. This mitigation program is great to help our children, the sick, and elderly during severe storms. The radio system will give schools, hospitals, nursing care facilities a better warning system for severe storms. This warning system will increase warning time and give employees adequate time to follow through with their......

Global Warming and Mitigation

...Andrew Mosolovich Week 9 Assignment Professor Pavlov 06/07/2013 Is our environment being compromised from excessive use of different chemicals? This is the question that has been the ground for major debate for many years, is our advancements causing global warming? When debating global warming the first thing to consider is what the cause of global warming is, and the answer to this basic question is greenhouse gases. Greenhouse gases are natural gases such as CO2, Nitrous Oxide or Methane and are created in one of two ways. The first way is, through natural cycles, for instance, CO2 is released through animal respiration or plant photosynthesis. The alternative greenhouse gas production comes from man’s use of different fuels and products; this can lead to anthropogenic climate changes. Anthropogenic Climate Changes are changes in the atmosphere brought on by human activity, and there is evidence of these kinds of changes all over. By studying the size of the polar ice caps we can see that they are shrinking and this may be due to a warmer atmosphere temperature brought on by none other than an anthropogenic climate change. An IPCC report from 2007 showing levels of some of the greenhouse gases also shows that the levels of greenhouse gases in the earth’s atmosphere has skyrocketed since the post-industrial era, this can only be attributed to man-made machines that have come to rise. So how does human activity attribute to the climate rise? Greenhouse gases are......

Global Warming: Cause and Mitigation

...Climate change is attributable to both natural and anthropogenic factors. Anthropogenic climate change, which are also known as human induced climate change, is a result of increase in greenhouse gases, including carbon dioxide, methane, nitrous oxide and chlorofluorocarbons in the atmosphere, increase in atmospheric aerosols, and changes in land use, for instance, through cutting down of forests to create farms. The increase in greenhouse gases in the atmosphere causes an increase in the amount of heat that is being retained and consequently, increasing the temperatures on the earth’s surface significantly. For example, the amount of carbon dioxide concentration in the atmosphere has risen by more than 30 percent since the industrial revolution (Mulvaney, 2013). Atmospheric aerosols absorb infrared and solar radiation and also change the chemical composition of the clouds, both physically and chemically. Industrial processes, human activity, biomass burning and exhaust emissions lead to chemical reactions, which consequently, form aerosols in the atmosphere. Changes in land use have also led to a significant increase in the sunlight reflected back into the surface. In North America and Eurasia, during the industrial era, it is estimated that one-fifth of land was attributed to agricultural activities and deforestation. On the other hand, natural climate changes can be a result of changes in suns energy and shifting of the orbit of the earth. Essentially, the earth’s......

Global Warming Causes and Mitigation

...warming: cause and mitigation Name: Institution: Introduction Global warming refers to climate change that causes an increase in the average temperature of the lower atmosphere. Though global warming has many different causes, it is greatly associated with human activities especially those that leads to release of greenhouse gases. This paper aims at evaluating both the scientific basis of global warming and the role of human beings in global warming. The paper achieves this by comparing natural and anthropogenic climate changes, providing evidence that global warming is taking place, and assessing carbon taxing and clean coal technology as current alleviation strategies for global warming. The paper finally proposes policy changes intended to stabilize global climate and points out nations and business sectors that would encounter strict standards on implementation of the proposed policies. Natural versus anthropogenic climate changes The climate change debate seems to be divided into two major sides. One side argues that the current global warming is caused by human factors while the other side credits global warming to natural processes. Although some scientists acknowledge natural processes as a cause of climate change, it has often been noted that there is no enough quantitative evidence to support that natural forces are dominant causes of current climate changes (Giddens, 2009). Many scientists credit the recent trends in climate change to anthropogenic causes. It is......

Global Warming: Cause and Mitigation

... Elizabeth Brabson | Global Warming: Cause and mitigation | Introduction To Physical Science | | Joshua Kyle | 3/3/2016 | The difference between natural climate change and anthropogenic can be summed up in relation with greenhouse gasses and how they are introduced into the Earth’s atmosphere. With the natural greenhouse effect, gasses such as methane and carbon dioxide are introduced naturally through such events as volcanic activity. In the anthropogenic greenhouse effect, those gasses are introduced by burning fossil fuels and from the intestines of livestock animals among other means. Also, due to deforestation and tillage of the ground, the Earth’s natural ability to store carbon is hindered. The Earth naturally maintains a level of homeostasis, when anthropogenic forms of greenhouse gases are introduced, it is too much for the planet to naturally maintain control of. Personally, I believe it as a slap in the face to the scientific community as a whole to deny climate change when there is a large amount of evidence to back up what 97% of scientist have pretty much agreed on. There are mountains of evidence, but I will present three. First and foremost, carbon dioxide levels are increasing substantially. Scientist have tested air bubbles in ancient ice from Antarctica and Greenland, and have determined that CO2 levels for the past 650,000 years or so have stayed between 180 and 300 parts per million. However, since the industrial revolution,......

Assignment 2: Global Warming: Cause and Mitigation

...Assignment 2: Global Warming: Cause and Mitigation Introduction to Physical Science xxxxxxxxxxxx December 6, 2015 Strayer University Professor xxxx xxxx One of the most all time debated and controversial topics to date in science is global warming. Over the last few decades climate change have lead scientist to develop a theories that human beings are the major contributors to the global warming crisis. Many theories suggest that different types of issues contribute to the warming of the planet but the mitigation strategies to slow this process down vary as well. When speaking of this topic there are two basic types of climate change, natural and anthropogenic. Main contributor in the climate change or global warming can be referred to as greenhouse gases. Greenhouse gases are derived from water vapor, Methane, Chlorofluorocarbons, and Carbon dioxide. Anthropogenic theory state that the development and consumption of fossil fuels for human life has generated and released a large amounts of carbon dioxide into the atmosphere. According to this theory the excess carbon dioxide is the main cause of climate change around the world. This process prevents heat from earth to escape naturally into space and hence cool the earth. The theory known as the natural theory states that the earth is going through one of the many peaks and valleys of changes. This of course being a peak of...

Hurricane Mitigation

...particularly when coinciding with natural high tides. This causes great potential for loss of life. They not only damage structures, but the debris which they carry is dangerous too. External debris can become deadly missiles in the wind force. Damage to tall objects, esp. power lines, telephone cables can cause disruption. High rise buildings are at risk from windows blowing out, particularly at higher levels, since wind speed increases with height. Winds can stay above hurricane level well inland. Comprehensive Emergency Management is the preparation for and the carrying out of all emergency functions, other than functions for which the military forces are primarily responsible, to mitigate, prepare for, respond to, and recover from emergencies and disasters, and to aid victims suffering from injury or damage, resulting from disasters caused by all hazards, whether natural, technological, or human caused, and to provide support for search and rescue operations for persons and property in distress (Wikipedia). When you think of local or State Hazard mitigation plans we took New Orleans’s plan for hurricanes before Katrina. Mitigation includes those activities, policies or programs developed and adopted by government officials which will reduce, eliminate, or alleviate damage caused by disasters. Proper and coordinated planning is a prerequisite to effective and efficient procedural changes required in addressing hazard mitigation. The City of New Orleans currently......

Stormwater Mitigation

...Storm Water Mitigation JoAnn Westerberg Research and Writing - ENG 215 February 26, 2012 Amanda Mc Clure Storm Water Mitigation While driving to work during a rainstorm, I noticed how much rainwater was pooling on city streets. Many roads become flooded because of the amount of rainfall and the inability of the storm drains to handle the amount of rainfall. After a heavy rainfall, hillsides comes tumbling down across roads. News reports from all across the country show how flooding occurs, washing away roads, trees and houses. This is a major problem country-wide causing millions of dollars of damage every year. How can this be prevented? There are many ideas to alleviate the problem of such flooding such as using rain gardens, grassy swales, and permeable pavement. A rain garden is a planted depression that allows rainwater runoff from impervious urban areas like roofs, driveways, walkways, and compacted lawn areas allowing the storm water runoff to soak into the ground instead of flowing into storm drains. Rain gardens decrease the amount of pollution entering into creeks and streams by 30 percent. Rain gardens are usually located near a drainage pipe or a roof. The benefits of rain gardens are improving the quality of runoff water, provide flood control, encourage wildlife and biodiversity, ties developments and environments together, and are pleasing to the eye. In 1990, Dick Brinker, a developer building a new housing subdivision in Prince George......

White Hat Inc will define risks as their priority to the company in terms of their impact on the company. White Hat will also help to define mitigation plans to resolve these risks. We will use several factors to prioritize risk and place each risk into one of three categories High, Medium and Low. To determine what category each risk will be placed we will use the following set of questions and definitions: • Define the Risk • Impact of the Risk on Physical or network aspect of the business • Cost of the Risk • Impact on Compliance • Recovery time and cost of lost business Throughout our audit we will generate several reports on the current status of IT security for The State. To Prioritize Risks for The State faces we will review these reports that include: • IT Security Compliance and Governance Gap Analysis • Data Privacy Legal Requirements and Compliance Requirements • Security Assessment • Data Privacy Security Gap • Security Assessment and Risk Identification • Qualitative Risk Assessment Definition of Risk Categories: • High- exploit of vulnerability that has a high cost to the organization's mission and reputation. This could also entail a risk of death or injury to humans. • Medium- exploit of a vulnerability where the cost of a resource would cause notable loss to the organization's......

...After researching the info on the subject matter. I have broken down the summary in two categories. They are risk, threats, and vulnerabilities in a Workstation Domain, and Risk mitigation tactics used to audit for compliance. Top risk, threats, and vulnerabilities in a Workstation Domain are as followed: • Unauthorized access to workstation • Unauthorized access to systems, applications, and data • Desktop or laptop computer operation system software vulnerabilities • Desktop or laptop application software vulnerabilities and software patch updates • Viruses, malicious code, or malware infects a user’s workstation or laptop computer • User inserts compact disks, USB’s, or DVD’s into a organizations computer • User downloads photos, music, or videos via the internet • User violates Aup and creates security risk for the organization’s IT infrastructure Below are risk mitigation tactics that can be used in order to audit for compliance. They are the following: • Enable password protection on workstations for access. Enable auto screen lockout for inactive times. • Define strict access control policies, standards, procedures, and guidelines. Implement a second-level test to verify a user’s right to gain access. • Define workstation operating system vulnerability window policy definition. A vulnerability window is the gap in time that you leave a computer unpatched with a security update. Start periodic Workstation Domain vulnerability tests to find......
