Abstract
An examination of the climatic global changes taking place. The author discusses the types of climatic changes occurring and their effects on certain geographical areas and on the environment. Also, a look at their long term impacts on society as a whole.

From the Paper
"Since the mid-1970's, scientists reported, the average global surface temperature has increased at a rate of about 3.5 degrees per century -- about the same rate estimated for the 21st century if emissions of waste industrial gases that trap heat in the atmosphere are not reduced. By comparison, the world has warmed by 5 to 9 degrees since the depths of the last ice age, 18,000 to 20,000 years ago."

Abstract
This paper relates that historians and archaeologists can trace numerous events to smaller climatic fluctuations, such as Europe's "Little Ice Age," which happened in the early Middle Ages bringing strange weather that caused famines, uprisings and withdrawal of northern Icelandic and Greenland colonies. The author points out that some people believe that the major threat to humanity is not diseases, crazed terrorist or the earth being bombarded by asteroids but rather world population growth. Environmental experts are concerned over how many people the earth's atmosphere can support. The paper stresses that a scientific consensus says the most direct result of the many gas emissions is a "global warming" of 1.5 to 4.5 degrees over the next millennium, and that is in addition to a more than evident temperature increase of half a degree.

From the Paper
"The Maldives, a chain of 1,180 islands in the Indian Ocean now sits three feet above the ocean's surface. In his Los Angeles Times article, "Maldives Faces Global Warming Goliath," writer Dexter Filkins says that "the entire nation could vanish, Atlantis-like, into the sea." Last winter, these island states crusaded for marked reductions in global greenhouse gases. While the US has proposed that industrialized nations began to reduce emissions in 2008 (at 1990 levels), the 35 nations Alliance of Small Island States insists on a 20 % cutback by 2005. While the exact danger (and its arrival) is unknown, island countries are anxious about a five-year study by the International Panel of Climate Change that predicts that by 2100, sea levels could rise from 6 inches to 3 feet. If such a dire forecast comes true, the ocean will swallow most of the Maldives. The country's main economic activity, tourism, would be devastated."

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."

Abstract
This essay looks at the consequences of climate change in Antarctica. The causes of climate change are examined. The impacts of climate change on the environment of the Antarctic are analyzed. Furthermore, some impacts that would result from climate change in the Antarctic, but would have global consequences mainly as the result of global warming, are also examined.

From the Paper
"The Earth's climate is changing and there is more and more evidence of global warming. This essay looks at these climate changes and its consequences, focusing in particular on Antarctica, as it is a very sensitive region yet of vital importance to the overall global climate. The Earth's climate has always oscillated, but unlike previously climate change in the last decades, has mostly been due to human activity also outlined in the essay. The changes are particularly drastic in a fragile environment such as the Antarctic and Arctic."

Abstract
This paper discusses the expected changes in climate and the ensuing affects on world agriculture. The paper claims that it is critically important to research climatic change since it affects everything on earth: man, beast, fish, fowl and organism. It also explains how climatic changes will affect the water temperature and the quality of the air.

From the Paper
"Climatologists now have stated it is with the realm of "certain probability" that humans absolutely have induced global climatic disturbances resulting in a complete change in current conditions. Furthermore, the affect that has been projected for human health is one stated to be of a nature that is diverse, "unpredictable in magnitude" and slow in emerging. Specifically stated is that the "Adverse effects are likely to outweigh beneficial effect substantially" (McMichaels, et al eds., 2004) However the changes that may be witnessed sooner rather than later are those experienced from the affects of agricultural production difficulties and disasters and mass failure of crops due to unforeseen tragedy and destruction within the earth's biosphere.

Abstract
The paper reveals that climatic conditions such as temperature, wind and humidity as well as atmospheric pressures and altitudes can affect the distance of a hit baseball. The paper offers real life examples that explain the physical impact of weather conditions on the baseball and discusses how these conditions affect the flight of the batted baseball. The paper reaches the conclusion that the climate definitely has a direct effect on the flight of the ball.

From the Paper
"Climatic conditions such as temperature, wind and humidity as well as atmospheric pressures and altitudes can affect the distance of a hit baseball which can be a determining factor in a game that's won or lost. The laws of physics determine how the air will move, how warm it will be and whether it is dry or damp.
"The physics of the flight of the batted ball are complex, according to research and the formulas that go into the calculation of possible effects on the flight of the ball. However, we can boil down the climate conditions that affect the baseball to very specific elements: namely, altitude, humidity, and wind. The effects of these climatic elements impose a specific effect on the ball once it is batted that affects its trajectory."

Abstract
This paper states that there has always been a natural variation in rainfall, temperature, and related conditions in certain parts of the world, leading to food insecurity due to variation of agricultural production. The author points out that existing socioeconomic effects often occur faster than the changes in the environment, which cause the socioeconomic changes, and thus, it is difficult to forecast them. The paper states that, because of climatic changes, the entire world will move into an unfamiliar situation, as human beings would be stepping beyond the limits that the world can provide them in support.

From the Paper
"For the 21st century, agriculture requires that it may be integrated as a total system with the components of environment, society and economy. Only this will lead to development for meeting the needs of the present generation and also take care of the next generation. It is now estimated that the people of the world will increase by almost 3 billion in the next fifty years, and most of this growth will be in the developing countries. This will happen in spite of the fact that even today, some 800 million people go hungry every day and another billion live a day on less than one dollar. This is the food insecurity and poverty that affects one-fourth of the population of the world. It shows clearly that we have not been able to take the necessary corrective actions in spite of the tremendous scientific progress and economic developments that are being made now. To meet our food security and poverty dangers, we must ensure that proper agricultural and rural development take place."

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 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
The paper discusses how environmental effects of deforestation are caused by dry lands, degradation, climatic changes and human activities. The paper explains that these contributions lead to global warming, which results towards destroying global biodiversity of life on Earth. The paper looks at how the United Nations Conference on Environment and Development (UNCED) in 1992 defines deforestation as "land degradation in arid, semi-arid, and sub-human areas resulting from various factors including climatic variations and human activities" (Innes 1).

From the Paper
"The process of deforestation in various geographical regions is wiping out the environment. Deforestation changes the environment by cutting down and slashing forests into open lands in an effort to raise crops for agriculture, urbanization and industrialization. The effects of deforestation are hazardous because it alters biodiversity, the ecosystem and environment and destroys our social surroundings. Deforestation is associated with carbon dioxide emissions into the atmosphere, which alters climatic changes. It is gravely important to replenish the forest or reforestation in an effort to have more biodiversity on Earth. The United Nations Conference on Environment and Development (UNCED) in..."
