Abstract This paper discusses how more and more scientists are now accepting that the world is undergoing unusual climate change. This paper examines the most important and likely ways that Atlantic Canada will be affected by climate change. The paper shows how climate change has the potential to have a devastating effect on the forests, farms and economy of Atlantic Canada. Natural Resources Canada reports that the latest analysis provided by the Intergovernmental Panel on Climate Change (IPCC) provides more scientific proof that climate change really is happening.
Abstract This paper reviews the impact that global warming has on human communities and ecosystems, and how it represents a great challenge for the entire planet. The paper reports that specialists recommend we try to find alternative sources of energy, and meanwhile, use less of the fossil-fuel energy. The paper further discusses the Kyoto Protocol.

Conclusion
From the Paper "Another issue is represented by the more and more often natural disasters like storms, floods and hurricanes that damage and even destroy people's establishments. The regions most vulnerable to sea-level rise are river deltas such as the Nile delta in Egypt, the Ganges in Bangladesh, the Yangtze and Hwang Ho in China, the Mekong and also the United States that could loose 8000 square miles (20,000 km2) of land, valued at about $650 billion, and 30-80% of its coastal wetlands . Insurance companies are also affected by the natural disasters that come along and in order to avoid bankruptcy they try to develop new strategies on the market and diminish the risks."

Abstract This paper discusses the changing global climate and the human activities contributing thereto. The writer describes scientific research which can improve our ability to predict climate change and its impacts and provide a basis for mitigating the harmful effects of global climate change. This can be done through decreased human influences, technological advancement, and finding ways to adapt and become resilient to extreme events such as earthquakes and hurricanes. The paper concludes that future studies and technological advancements will pave the way for us to restore and repair our injured climate.

Introduction
Changes to the Climate Caused by Human Activity
Improving Changes in the Climate Conclusion
From the Paper "A great deal of scientific research has noted the harms to the environment caused by human activity. The majority of these harmful activities have had a profound impact on the overall climate. The climate of an area includes the temperature, weather, water levels, and overall air quality of an area. Human activity such as garbage dumping, urbanization and even artificial restoration of an area have contributed to negative climate patterns. In response to these harms, new plans for growth and expansion that have "environmentally friendly" goals have been initiated throughout the United States as well as other parts of the world."
Abstract This essay examines a marine ecosystem and a forest ecosystem and identifies and ranks the three most important ecosystem services that are provided by these two systems, describing the nature of the relationship between two of the ecosystem services and the well being of humans. Furthermore, the essay discusses the most significant direct and indirect drivers of degradation within the two systems and discuss the scenarios that would best protect them as well as the scenarios that are most likely to happen.
Abstract This paper examines two instances of ecosystem development--one instance being primary succession, the other instance being secondary succession--and explores how abiotic and biotic factors can create and/or perpetuate a ecological system. The paper concludes briefly by looking at the various mechanisms which hinder or help an ecosystem recover after a catastrophic event.
From the Paper "In our course textbook there are two especially interesting illustrations. The first of these depicts primary succession on a glacial moraine in Glacier Bay, Alaska. In this instance, the barren, rocky landscape is colonized by lichens and mosses and shrubs. Afterwards, dwarf trees and more mature shrubs emerge and then spruces come to predominate. In the second illustration, we are confronted with secondary succession in North Carolina wherein, after one year after cultivation, there is the emergence of crabgrass and then the subsequent emergence of annual and perennial weeds. A few years later, pine seedlings and saplings develop and these are followed by young pine forest and by the developing "under-story" of hardwoods. Finally, 150 years after the field was first abandoned, there is a mature hardwood forest present."
Abstract This paper presents an in-depth look at the water toxins and the way they affect the ecosystem as a whole. The writer takes the reader on an exploratory journey through the ecosystem and the way it works. Then it discusses the way water toxins and pollution are destroying the system by killing the marine organisms. Finally, it concludes that in the future it will be imperative to find ways to thwart the water toxins affects.
From the Paper "Because we have lived on this planet for millions of years, we have come to rely on its ability to support and sustain human and animal life indefinitely. The world survives by way of an ecosystem and that system is the core of all living things. For many years now scientists have warned that our cavalier attitude toward preservation of the eco system will cause it to begin breaking down, however, their warnings often fell on deaf ears. Now it is time to pay the piper. Recently scientists have begun to take a close look at the cycles of life and the way they are intertwined in the ecosystem. There is strong evidence that toxins are destroying the ecosystem because the abundance and diversity of marine organisms is rapidly declining(Liat pp 142)."
Abstract This paper begins by describing the current situation of marine ecosystems around the world and looking at the damage they suffer as a result of pollution. The paper explains that marine ecosystems are being altered because of oil spills and other human-mediated activities and then takes a look at the effects of this pollution.
The following paper discusses the climate of the U.S.A. and Canada, with respect to the climate classifications, its effects on farming and other activities.
Abstract This essay discusses how climate governs the entire ecological structure of the planet earth. The author examines how climate, in relation to the topography and latitudinal location, determines the vegetative types, the hydrology, soil, agriculture, and various human activities.
From the Paper "Climate represents a long term average of various weather features such as temperature and precipitation. The World Meteorological Organization uses 30-year averages to define climatological "normals" for these various features. Climate determines how resources such as water and vegetation are distributed and, until the onset of technology, climate also determined where people lived and worked. Many factors, such as topography, proximity to large bodies of water, and latitude affect a particular location's long-term climate. It is important to note that because a region's climatology is a 30-year average, significant year to year variability is likely. For example, a particular location may have a dry, warm winter one year and a record snowfall the next year"

Abstract This paper analyzes various studies of climate change and its effect on human culture in the Great Plains area of the United States, citing climate change on prehistoric cultures in southern high plains of Texas and New Mexico, determining what the climate change in the region of the Southern high plans may have been and examining changes in the culture of the native population that resulted from this change.
From the Paper "In this era of concern about global warming, more and more research has been conducted into climate change in the past. One area of such research has been into the impact of climate change on prehistoric cultures in southern high plains of Texas and New Mexico, determining what the climate change in the region of the Southern high plans may have been and examining changes in the culture of the native population that resulted from this change. From such research, certain patterns have emerged and have engendered further study."
Abstract This paper discusses the consequences of climate change in Antarctica. The essay is divided into three sections. The first section looks at the nature of Antarctica. The second section examines what global warming and climate change will do to Antarctica and the final section looks at the global consequences.
From the Paper "Global warming and climate change are two closely connected environmental problems. Although global warming and climate change will affect the entire world, different areas will be altered in different ways. Also changes in one area can lead to changes in other areas. For this essay the consequences of global warming and climate change will be examined in detail. In order to examine these issues the essay will be divided into three sections. The first section will look at the geography, natural resources and ecological nature of Antarctica. The second section will examine the effects of global warming and climate change on Antarctica."
Abstract This paper discusses a study relating to human influences on climate, and whether or not the contentions within the research are based upon accuracy. The paper further reviews the article from Karl and Trenberth, discussing the viewpoints of the authors, and the impact of the study on society. Finally, the paper discusses further research that both supports, and refutes the findings of Karl and Trenberth. This research is important because it focuses on what is factual, and whether or not there is any evidence to support contentions that humanity is destroying the earth, and the climate worldwide.
From the Paper "Thomas R. Karl and Kevin Trenberth (1999) suggest that a significant amount of discussion has been created relating to humanity's influence on the destruction of the global climate (p. 101). The authors contend that government organizations determined that humanity is contributing in a variety of ways to the deterioration of the climate, but that no evidence has been accumulated to support this assumption (Karl & Trenberth, 1999, p. 101). Yet, despite the assertion that no factual evidence has been collected to date that would provide specific data for further study; the researchers have addressed the issue with contentions that may be useful if future studies are conducted. Karl and Trenberth (1999) describe their article as relevant because it proposes to make suggestions based on facts that may lead to future research specifically focusing on data which demonstrates human factors in relation to climate (p. 101)."
Abstract In this essay the writer offers a short overview of Martian climate. First, the composition and characteristics of Martian atmosphere are presented. Then the major features of Martian climate are given with a special emphasis on wind formation. The final part is devoted to dust formation and dust storms on the Red Planet. A short fact-sheet about the planet is provided as introduction.
From the Paper "Mars is the fourth planet of our Solar System. Its average distance from the sun is 2.28 x 10^8 km, which is 1.54 times larger than Earth's average distance. As a result Mars years are much longer - 687 Earth days. Compared to Earth's orbit, Mars' orbit is more elliptical bringing the planet 206.5 million km from the sun at perihelion and 249.1 million km at aphelion."
Abstract This paper talks about how latitude is arguably one of the most significant determinants of a region's climate. First, what is latitude? The paper explains that latitude is the angular measurement of a location's distance north or south of the equator. The equator is delineated as 0 degrees latitude. The poles are alternately 90 degrees north or south latitude ("Latitude" par. 1). All other locations fall somewhere in between these two extremes. Thus, when we know a location's latitude we implicitly know that location's distance north or south of the equator. For example, Honolulu, Hawaii is at 21 degrees north latitude. Honolulu, consequently, is much closer to the Earth's equator than Phoenix, Arizona with a latitude of 33 degrees north. This difference accounts for significant climatic variation.
Abstract An examination of Milankovitch's theory which links the climate to seasonal and latitudinal variations in the solar energy received by the Earth. Through this theory we are given a better understanding of this time period. Criticism of the theory is also discussed and problems analyzed.
From the Paper "An ice age is a cool period in Earth history, where much of the Earth's land surface is covered by ice. What is most relevant here is that an ice age is defined by the lower temperatures, with the ice a symptom of this. An ice age then, can be defined as a period when climatic changes produce lower temperatures, which in turn cause the Earth to be covered by large sheets of ice."
