...all of these deadly and destructive anomalies. Some claim an apocalypse is coming, some say we are heading toward an ice age, some believe we have accelerated a change in the Earth’s climate cycles by our own actions. Any view taken, is one of fear and trepidation. As a factual and unbiased paper, we will not take the Apocalypse theory into account for the fact that there are concrete facts or evidence. Regardless of why we believe something is wrong or changing, it is undeniably fact that the world is changing on many levels. The purpose of this paper is explore and attempt to find the reasons why this is happening, and what we, as mankind, can do to be prepared, and to attempt to mitigate any effect we may have on the acceleration of these changes Pollution and human consumption of fossil fuels, trees and other natural resources have been the scapegoat for “global warming” for several years now. How is it that, specifically, carbon emissions from vehicles allegedly has caused or sped the rate of global warming? Carbon emissions have been in existence since fossil fueled engines have been around, which is roughly between 150 and 200 years at this point. How could something happening in such a very short part of a climate cycle possibly have an effect on how rapidly or slowly the cycle may be changing? 3 “...a sign of global warming -- which most readers presumably took to mean "anthropogenic," or human-caused, global warming. But is that the...

...dissertation examines the Australian ‘Emissions Trading Scheme’ (ETS) and why it is such a fiercely debated topic in politics, industry, community groups and the general public alike. It explores the ways in which the topic of global warming and climate change has significantly altered Australia in numerous aspects and particularly investigates the Rudd Governments’ decision to introduce an emissions trading scheme. The emissions trading scheme came on the back of The Garnaut Climate Change Review which presented its draft report on 4 July 2008 (with the final report submitted in September 2008). Upon receiving the draft report, Climate Change Minister, Penny Wong, issued the Government discussion paper on emissions trading, titled Carbon Pollution Reduction Green Paper. Since this paper was released, and the recommendations stated, turbulent times for all involved has ensued. With the ETS to be made effective sometime in 2010, the government has had to fight tooth and nail in the Senate to get it (the ETS) passed in time for the scheduled deployment. In this piece, both sides of the case will be looked at and a decision on whether the proposed ETS is an effective measure to combat global warming and climate change will be presented. Is an emission trading scheme the right path to alleviate global warming for Australia? Global warming and climate change. Two terms that are constantly thrown around in the Australian media but what do they actually mean? Simply put; global warming...

...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 natural...

...chip (die). APU-based platforms can deliver a prodigious amount of computational horsepower, and can present enormous opportunities in developing an application ecosystem beyond today’s mainstream computer systems. While APUs seek to deliver a superior, immersive PC experience, they also can provide tangible environmental benefits. By eliminating a chip to chip link and by introducing new holistic power management techniques, the APUs are designed to be more power efficient than current generation platforms that have both computational and graphical capabilities. This paper compares the environmental impact of one of AMD’s first APU products against an equivalent computer platform powered by the current generation of AMD processors (CPUs and GPUs). By conducting a business to consumer (B2C) lifecycle assessment, this study compares the total lifecycle greenhouse gas (GHG) emissions (also known as a “carbon footprint”) of an APU system (based on the 18W dual-core processor codenamed “Zacate” and the M1 chipset codenamed “Hudson”) with the latest AMD system codenamed “Nile” (which is based on an AMD Athlon™ Neo II Dual Core processor, SB820 Southbridge, RS880M Northbridge with an ATI Mobility Radeon™ HD 5430 discrete graphics card). This study concludes that the APU system offers significant GHG benefits (up to a 40% emissions reduction) when compared with the Nile platform.

...Phase 1 Individual Project SCI201-1403A-12 Environmental Science and Sustainability July 10, 2014 Trena Woolridge Just to keep the theme going from the discussion board 2 assignment I decided to research and write about the Tropical Rainforest. I have always found the world’s rainforests to be very interesting with all of their secrets they hold inside of them. By doing this paper it will allow me to discover more in-depth information on the Tropical Rainforests. I wonder what all I will discover? There are many rainforests in the world but can be found only in three major geographical areas around the world. The one that stands out the most to me is the Tropical Rainforest in Central America in the Amazon Basin from the previous assignment I researched. Others are located in Africa, Australia, and Assam to name a few. Tropical Rainforests are made up of large trees, exotic wildlife, and thousands of species of plants. The structure of the Tropical Rainforest is very complex but can be simple to understand when broken down into sections. The rainforest can be divided into layers from top to bottom and can get a better understanding of the Tropical Rainforest as a whole. The different layers are: emergent, the canopy, the understory, and the leaf litter or cryptoshere or also known as the ground. Emergent are the larger, taller trees that stick out above the canopy. They can be 20-100 feet above the canopy and endures strong winds, temperature fluctuations, and damaging...

Natural Resources Defense Council issue paper Commercial Nuclear Power EXECUTIVE SUMMARY Because of the sheer magnitude and urgency of the global climate challenge, the United States must consider all forms of energy—as long as they do not otherwise undermine international and environmental security. Unfortunately, the nuclear power industry in its present state suffers from too many security, safety, and environmental exposure problems and excessive costs to qualify as a leading means to combat global warming pollution. Large-scale nuclear plants remain uneconomic to build. And while the nuclear fuel cycle emits little global warming pollution, nuclear power still poses globally significant risks that need to be further reduced, including:...

...21 October 2014 Review of: Linkages of plant traits to soil properties and the functioning of temperate grassland The researchers and authors of this paper looked at the idea of plant-soil interactions and how their traits can be a tool to help understand ecosystem functions. Global climate change has affected many factors involved in ecosystems and their functions, and this will continue to happen. A very likely outcome of continued climate change is the changing of plant communities and their traits. This in turn affects the surrounding soil, and that will have an impact on the nutrient cycling which rely very heavily on the soil to be the mediator. Most of Earth’s processes and functions are interconnected and are difficult to alter without having an effect on something else. The relationship of plant traits to ecosystem properties can tell researchers a great deal about the current state of the ecosystem and the kind of functions that are present. Key nutrient cycles such as nitrogen, phosphorus, and carbon are intricate and affected by many factors. The researchers of this paper believed that by studying the plant traits and soil properties they could gain a better idea of these cycles and the way that they are affected. Their main goal was to determine whether or not the traits of co-existing grassland species grown with different growth strategies would have an effect/differ the soil properties. They measured the plant traits on fresh leaf, litter, and root...

...which results in global warming; however, global warming may just be caused by natural occurrences, such as cosmic rays, the sun, volcanic activity and the ocean. The combustion of fossil fuels input enormous emissions of CO2 into the atmosphere causing the atmospheric CO2 levels to rise radically. The academic textbook, Contemporary Environmental Issues states, “CO2 is the principal gas contributing to the enhanced greenhouse effect…three main greenhouse gases, CO2, CH4, and N2O, are rising because of human activities such as the burning of coal, oil, and natural gas” (Turk & Bensel, 2011). Levels of greenhouse gases in the atmosphere have increased substantially through the industrial revolution. In particular, the concentration of carbon dioxide in the atmosphere has increased by roughly 35 percent since...

This motivated me and strengthened my desire to explore and search for answers to questions I had crafted in an attempt to understand nature and its role in our lives. I was privileged to study cellular and molecular biology under one of the most experienced professors at this University. In this class, I gained a holistic view of nature. This was a challenge initially as I had to comprehend how intimately the various parts of our ecosystem were interconnected; from the carbon cycle to the invertebrate and fungi population. At the end of the semester, using information and data collected previously, I presented a research paper explaining the effects of land management practices on carbon sequestration in Costa Rica. I studied deforestation in Costa Rica and some viable reforestation techniques. Writing this paper gave me some background knowledge on the tropical forests of Costa Rica.

...Ecosystem Structure, Function, and Change Paper (Great Lakes) Shantera Bell October 26, 2015 SCI/256 UOP The Great Lakes region is rich with life and full of native species well adapted to survival. However, since the early 1800s, many non-native plants, animals and microscopic organisms have been introduced into the Great Lakes, either accidentally or intentionally. Great Lakes native species are diverse and interesting and contribute to a healthy ecosystem. There are many unique and interesting birds, fish and plants found in Michigan and throughout the region that are integral to the health of the Great Lakes ecosystem. More than 140 species of birds depend on Michigan’s coastal habitat during their life cycle. Coastal wetlands, beaches, sand dunes and remote islands provide food and shelter for both resident and migratory species. Waterfowl such as Canvasback and Scaup are among the many species that use coastal wetlands as stopover sites to rest and refuel. Shorebirds including the endangered piping plover fly thousands of miles to nest on undisturbed beaches and remote Great Lakes islands. Because of their use of the coastal lands, there are thousands of great locations to see both resident and migratory bird species throughout Michigan and the Great Lakes region. State parks, national parks, wildlife refuges and sanctuaries throughout the state all provide good bird-watching opportunities. Some sites along Michigan’s Great Lakes shoreline are even...
