These two scenarios are polar opposites posited by two sides of the global warming debate. The third prong of the global warming trisects asserts that scientific knowledge to ate is insufficient to develop a theory of the causes or effects of Global Warming Global Warming Mission plan a. Analysis of the problem 1. History Of the Problem Some scientist’s have been concerned since 1896 about what might happen if there were 5. 5 global warming and therefore should not be the basis of public policy on the issue.

The debate is intense. The three positions all seem to agree that the temperatures around the globe have increased over those in recent years, but considerable disagreement and insufficient concrete evidence concerning the possible effects of such warming, together tit its causes, indicates that drastic and expensive mandates are premature and warrant further study.

During the course of the twentieth century, many environmental scientists have become increasingly confident that the average global temperature has elevated. Although . Recently is the one issue upon which both sides of the global warming controversy seem to agree. According to an editorial in The Wall Street Journal, the average surface temperature globally has increased about 1 agree Celsius during the 20th century. Other sources indicate that the increase has been about 1 degree Fahrenheit.

Some data, including data obtained from study of tree rings and ice cores, indicates that this increase is likely to have been the largest of any century Global Warming FETISHISM MARKINGS The greenhouse effect and global warming are issues that are talked about by geologists all the time. The greenhouse effect is a natural process that keeps the earth during the past millennia. Some scientists indicate that the pattern farming is consistent with the warming hat would be expected from an increase in the levels of carbon dioxide, or CO. These same scientists have observed changes in snow and ice, which have decreased.

The sea level has increased by 10 to 20 centimeters, and the heat content of the ocean has also increased. While the two sides of the global warming issue do agree on the fact Of Global Warming Global Warming The greenhouse effect, in environmental science, is a popular term for the effect that certain variable constituents of the Earth’s lower atmosphere have on surface temperatures. It warming, the agreement ends there, with one side claiming the issue is one for great alarm and the other asserting that the warming is one of countless trends in warming and cooling that has taken place on the planet in its billions of years of existence.

To provide some context, periods of global warming and cooling have taken place many times throughout the Earth’s billions of years. In addition, levels of CO have increased and decreased countless times during The humanity is currently facing one its biggest problem ever. Indeed, the Earth is warming and consequences might be devastating for the future generations. There is a general agreement among Earth’s history. For example, CO levels were 18 times higher during Cambrian Period (550 million years ago), than they are today, accompanied by an explosion of life during that ancient time.

Such levels were nine times higher during the Jurassic period, when dinosaurs lived, than they are today. Evidence reflects that during the last 400,000 years, the Earth has experienced a series of ice ages lasting about 100,000 years, each Of which is followed by a warming period of Global Warming 3 Life is Changing Global warming is the most urgent environmental problem limited change caused by about 10,000 years. In the year 1 ,OHO A. D. , the Earth’s climate was much warmer than it is now. The latest ice age, often called “the little ice age,” occurred during the period from the asses through the mid asses.

Most of this century warming occurred before 1940. According to one source, the climate has experienced some cooling for several decades after World War II. Another asserts that the decade of the asses was the hottest decade on record. The Environmental Affects Of Global Environmental effects of global warming The greenhouse effect and global arming are issues that are talked about by geologists all the time. The greenhouse effect is a natural process that globally averaged surface temperature is projected to increase by 1. 4 to 5. 8 degrees Celsius by the year 2100.

The lack of debate about whether temperatures have recently trended toward warming sharply contrasts with the abundance of debate on the possible effects of such warming, an issue on which one side focuses. The effects of warmer temperatures in recent years range from cataclysmic to neutral to beneficial. Some assert that the trend will result in increased roughs, floods, environmental affects of global warming greenhouse effect is a natural hurricanes Of greater intensity, coastal flooding and extinction of species that cannot adapt.

Among the predictions: still warmer temperatures, rising sea levels, intensification of the hydrological cycle, adverse health effects, detrimental effects on all of the world’s ecosystems, and a decline in flexibility of crop production. Some predict that the warming trend experienced during the 20th century and into the 21st century will continue through and after the year 2100. Surface temperature increases are projected to increase from 1. 8 Environmental Affects Of Global greenhouse effect is a natural to 6. 3 F in the next century, with scientists’ best guess being about 3. F. This contrasts with a prediction that the increase will be about 1. 4 to 5. 8 degrees C, and still another prediction that the increase will be 15 to 20 F above the present day mean annual global surface temperature. In a prediction which assumes that CO levels cause warming, scientific modeling suggests that the surface temperature will continue to increase beyond the year 21 00 even Global Warming 2 Carbon dioxide plays a major part of impacting the Earth s climate. Carbon dioxide traps heat form the sun.

This effect is considered global warming which is often if concentrations of greenhouse gases are stabilized by that time. The same assumption is made in the prediction that, if carbon dioxide emissions continue to increase at present rates, a quadrupling of pre- industrial CO concentration will occur shortly after the year 2100. The increase in global temperature has been projected to be accompanied by a rise in sea levels. The levels of the sea have risen since the end of the last ice GE, rising 4 to 10 inches Global Warming In the last century, the earth’s surface temperature has increased 0. 5-0. 60 degrees Celsius. Although some scientists believe global warming is not a problem, many scientists believe that global warming during the 20th century. Sea level is projected to rise by . 09 to . 88 meters, or between 6 to 37 inches between 1 990 and 2100. The levels could rise even more, depending on the concentration of CO levels in the atmosphere: 550 parts per million, double the pre-industrial levels, would result in a sea level rise of greater than 0 inches, or 80 inches if the CO levels quadruple to 1 1 00 pimp.

Sea level rise increases the vulnerability of coastal Global Warming There are many problems concerning the environment. Pollution, destruction of the rainforest’s, and the consumption of all of our planet’s natural resources are just a few. None of these issues populations, said to be 46 million, to flooding and causes land to be lost to erosion. The number of people affected by rising sea levels is predicted to increase to 92 million with a 50 centimeter sea level rise or 1 18 million with a 3-foot rise.

A one-meter increase in sea level will be enough to flood 1 percent of Egypt, 6 percent of the Netherlands, 17. 5 percent Of Bangladesh, and 80 percent Of the Major Atoll in the Marshall Global Warming Global Warming Global warming is a huge environmental and economic challenge that we are facing in the 21 SST century. Global warming is also commonly referred to as the greenhouse Islands. Rising waters might force the occupants of numerous small island nations to migrate elsewhere, as many of them lack the coastal defense systems to cope with higher water levels.

In addition to increased sea levels, some predict that the hydrological yes will intensity, resulting in more frequent and severe droughts and floods. The hydrological cycle, the circulation and conservation of earth’s water, would intensify and cause drastic droughts and floods, according to sources. Warming will likely result in Global warming In the article “Happiness Is a Warm Planet” it tries to explain and tell how Global Warming is a good thing.

It says “mankind should benefit from and upward an increase in the amount of water exchanged among the oceans, atmosphere, and land. Increasing rates of evaporation will likely result in drier soils. An accelerated hydrological cycle means greater amounts of precipitation in some areas and will probably result in more frequent and severe droughts and floods. This prediction has been said to be linked to two 1 00-year floods which Occurred in fewer than five years in the Midwestern United States during the asses.

Significant changes in water volume, Global Warming Global Warming As the new millennium quickly approaches, scientists, politicians and the people of the world are beginning to have more and more concerns about the future of the earth distribution, and supply are redirected and will likely have a dramatic impact on regional water resources. According to the World Bank, one-third of the world’s population already suffers from chronic water shortages. The Wristwatch Institute predicts that this situation will be exacerbated further by the addition of an estimated 2. Billion people to the world’s population over the next 30 years. By 2025, the group claims, some three billion people or 40 percent of the world’s population Global Warming Global Warming”We have an obligation to weigh the risks of inaction against the cost of action. In that regard, global warming is no different than any other problem. Could be living in countries without sufficient water supplies, leading to crop failures, diminished economic development and even to regional conflicts as nations find it necessary to fight for control over scarce water resources. The opposite is also claimed.

Global warming would mean more condensation and more evaporation, producing more and/or heavier rains. Global warming, therefore, could offer the answer to the water scarcity problem that the Wristwatch Institute has been seeking. Hurricanes is another area of prediction global warming Global Warming Global Warming, aside from pollution is one of scientists biggest concerns. Global Warming is caused by the Greenhouse effect. There are 4 Steps in the Greenhouse in connection with the global warming controversy, With those on one side indicating that global warming will increase the strength of hurricanes.

However, others indicate that neither the number and strength of hurricanes has increased outside natural range of variability. The decade during the asses had 10 of 24 hurricanes in categories three, four, and five, those considered “major. ” An average of nine major raciness occurred in each of the decades of the asses, asses, and asses. Ninety-two giant hurricanes global warming are 4 struck the mainland of the United States been 1 851 and 2004, 61 of them before 1950. Had . Canes. The peak for major hurricanes (categories 3, 4 5) came in the decades of the asses, 1 sass and asses an average of nine per decade.

Of the 92 giant hurricanes that have struck the U. S. Mainland between 1851 and 2004, 61 of them occurred before 1950, long before global warming was an issue. “Strain is part of a global warming are 4 steps in the Greenhouse effect. I-Sunlight well-documented, latitudinal scale fluctuation in hurricane activity,” said Stanley Goldenberg, a meteorologist at the Hurricane Research Division of the National Oceanic & Atmospheric Administration, who wrote a paper published in 2001 in the journal, Science. If you look at the raw hurricane data itself, there is no global warming signal. What we see instead is a strong cycling of activity. There are periods of 25 to 40 years where it’s very busy and then periods of 25 to 40 years Global Warming are 4 steps in the Greenhouse effect. I-sunlight when its very quiet,” said scientist Chris Lands, also of the administration. According to the Woods Hole Research Center, a warming earth will most negatively impact health in the form of heat-related deaths.
