Global Warming Myth or Reality Assignment

Global Warming Myth or Reality Assignment Words: 1913

The earth is at once going through a normal cycle in which there is a warm age, through global warming due to greenhouse effect, and much cooler temperatures during winters. This can mislead people into thinking that the earth is not warming up or that it is warming up simply due to increasing sunspots. They would actually be mistaken. These facts happen to be all right through coincidence or consequences of the other. Global warming is a term on the lips of many people these days. Just what is global warming? Should people be worried?

What can be done to stop global warming? Should it be stopped or ignored? These are just some of the questions that make up the current debate in the topic of climate change and its effect on life on Earth now and in the future. First of all, a definition: Global warming is a perceived increase in temperature around the world. Weather trackers and forecasters keep tabs on temperatures all round the world, every day of the year. These geographers and scientists determine the average temperature for a place or a region, a country, or a continent.

Putting all those figures together can give people an average worldwide temperature. And it is that average worldwide temperature that weather-watchers say is owe increasing. Some people would say that the temperature is increasing at an alarming level. What is certainly true is that the increases in temperature are happening more quickly now and in the past decade or so than at many times in history. One prime cause of this increase in worldwide temperature is the sharp increase in greenhouse gases. They are called this because like greenhouses, they keep heat in the atmosphere.

Chief among these greenhouses gases is carbon dioxide, which is produced by the burning of fossil fuels, like coal, oil, and gasoline-The more greenhouse gases are reduced, the more they flood the atmosphere, preventing heat from escaping and, in fact, reflecting it back toward Earth. This heat is nowhere near the heat produced by the Sun, but it is definitely heat that affects life on Earth Another prime cause of the rise in worldwide temperatures is the activity of the Sun itself. The star that is at the center of the Solar System has been demonstrated to be getting hotter.

It is certainly not anywhere near the end Of its life, but it is going through a period when its core temperature is rising, causing an increase in the heat and radiation that the star itself gives if. All of this heat and radiation streams outward, bombarding Earth on a daily basis. The result is hotter temperatures all round. The hotter temperatures are, the faster glaciers melt. Glaciers, massive chunks of ice, make up a large part of Antarctica, Greenland, and other land areas in the far north and south. As temperatures change, glaciers can break free and float in the world’s oceans.

More significantly, the more they melt, the more water they add to those oceans and the higher world sea levels get. Land that borders the world’s oceans can be at the mercy of that water. Hurricanes and hyphens can buffet coastal lands. Rising sea levels can spell disasters for houses and buildings right on the coast. Sustained increases in sea levels can cause flooding on a mass scale. Scientists can definitely prove that the average temperature has gone up around the world. Many places have reported increases in temperatures. Some of these increases are more dramatic than others.

Not all places have recorded rises in temperature, however; in fact, people in many places on Earth have reported an overall decrease in average temperatures. The average worldwide temperature is still limning, though. Another result of hotter temperatures is a decrease in rain. As rainfall drops, a place can get hotter and hotter. As a result, crops can be harder and harder to grow and water to feed those crops and help survive the people who grow them can get more and more scarce. People can misjudge the increase in rainfall and decrease in temperature for a cold age instead of global warming.

They can also misjudge the increasing temperatures in some countries for a warm age while a warm age cannot occur and affect the earth as quickly as it is being affected due to the greenhouse effect. Although there are many changes in the world showing global warming, some scientists still find reasons for all of them that do not include global warming and the greenhouse effect. They state that recent climate developments are not something unusual and that they reflect a natural course of planetary events.

Global warming has finally been explained: the Earth is getting hotter because the Sun is burning more brightly than at any time during the past 1 ,OHO years, according to new research. A study by Swiss and German scientists suggests that increasing radiation from the sun is responsible for cent global climate changes. Dry. Same Isolation , the director of the renowned Max Planck Institute for Solar System Research in Getting, Germany, who led the research, said: “The Sun has been at its strongest over the past 60 years and may now be affecting global temperatures.

They say that over the last century the number of sunspots rose at the same time that the Earth’s climate became steadily warmer. Global warming and melting polar ice caps are not just problems here on Earth. Mars is facing similar global changes, with temperatures across the red planet rising by around 0. 65 degrees over he last few decades. From time immemorial, alternate warm and cold cycles have followed each other, with a periodicity ranging from tens of millions to several years. The cycles were most probably dependent on the changes occurring in the Sun.

As for the short term changes, which occurred in the few recent year, are caused by terrestrial factors such as large volcanic explosions, which inject dust into the stratosphere, and the phenomenon of II Infix, which depends on the variations in oceanic currents. As many debate that the world is warming up, some still reject that idea, thinking that the oral temperatures have been going down instead. China has its coldest winter in 100 years. Baghdad sees its first snow in all recorded history. North America has the most snow cover in 50 years, with places like Wisconsin the highest since record-keeping began.

Record levels of Antarctic sea ice, record cold in Minnesota, Texas, Florida, Mexico, Australia, Iran, Greece, South Africa, Greenland, Argentina, Chile, and many others. The evidence has been supplanted by hard scientific facts. All four major global temperature tracking outlets (Hadley, Anna’s GIGS, SHAH, IRS) have released updated data. All show that over the past year of 2010, global temperatures have dropped precipitously. As much as we would like to believe that there IS no global warming occurring, we cannot pretend we don’t see the changes and deny all the scientific proofs.

Humans use up the earth’s natural resources, which are a part of the natural causes of global warming, they tend to change the environment around them. The Earth will always change because of the natural causes of global warming but humans are actually the catalysts of the increasing global warming and catastrophes occurring in the world. It is pedaled proved with substantial examples that the world is going through such a catastrophic situation due to human sources. While it is shown that there have already been other warm ages in the opposite argument, there have never been as many natural disasters as there have been in this last decade.

Glaciers have been melting, causing floods, hurricanes destroying cities and even earthquakes breaking down thousands of homes. The evaporation from the oceans also causes climate disasters, which have never occurred at this rate before. Although many debate that the world is actually acing its coldest winters since hundreds of years, it is simply due to the global warming. The summers become much warmer and the Winters much cooler. The evaporation causes floods in China, India, Australia, the US and other areas while there have been droughts in other parts of the US, Australia, and south Africa.

Although glaciers have always partly melted and broke down, as shown in the “Global Warming Swindle”, there has never been as many glaciers completely melting away as there have been this last decade. In ” The Inconvenient Truth”, we can see many examples that prove he recent change in climate, which had never occurred to this extremity in the past. The huge glacier in Argentina has completely melted and is now only a lake. We can also see how the tundra in Alaska is being affected since the permafrost is melting during the warm summers and the treeless dry lands in the Arctic now include trees and lakes.

In Greenland where there has not been agriculture for decades, there has been a recent return to agriculture since the weather is warmer and crops can now survive. The Arctic icecap has now become 40% thinner and is causing major problems such as transport, which can only take place a few months during the year when the ice cap is thick enough. In different parts of the world, there have been various weather events such as strong rains, floods and very low record breaking climates that would let think that the world is not warming up.

While climate change is a long process that affects the weather, these cold weather changes are only short-term events. As a planet is becoming warmer, the climate patterns are altered every. Veer at all times of the years. A warming planet can cause increasing cold, rain and storms through out the world. As the Global Warming Swindle” explains how animals and oceans release ICC, in AY Gore’s documentary we can see that the ICC levels have never reached such a high level, causing the world to heat up, and humans are to blame.

As the population grows, there is more agriculture thus more animals produce more ICC. As humans are weakening the ozone layer by using fuel and releasing ICC, the radiation levels increase causing the ocean to warm up and release ICC instead of storing it if it were cold. As the change in climate is talking place, animal cycles are disrupted and soon, the animals will not be able to revive and cause problems in agriculture and animal survival. More and more animals are getting extinct as their normal habitats are getting altered due to the change in climate.

Polar bears who have existed for thousands of years are now almost extinct due to the melting of glaciers. Global warming exists and it should be handled very carefully since the consequences are already starting to harm human, animal and plant lives. As some scientists come up with proof of global warming through greenhouse effect, others come up with proof of a warm age. The fact is that both are right and both are taking place. The one caused in the long term effect is the is the warm age which is a normal cycle that happens every couple of hundred years.
