Essay about Global Warming - A Natural Process

NGS integrates greenhouse into other major policy initiatives, such as the Natural Heritage Trust, and launches new measures to increase greenhouse emission reduction activities across the Australian community. It provides the strategic framework for an effective greenhouse response and for meeting current and future international commitments. It will provide a fresh impetus for action by governments, stakeholder groups and the broader community and set directions for that action into the next century.

Global Warming is an increase in the average temperature around the world. Scientists have been able to trace the global climate and concluded that over the last ten thousand years, the climate of the earth has been relatively constant. In the twentieth century, the global temperature increased 0.740°C. The change in the warming, and cooling, of average global temperatures cause climate change, a change related to climate patterns such as temperatures, rainfall, wind and humidity. This flux in temperature is affected by multiple factors making it hard to determine the true source of problem. Evidence supports that the earth's warming is natural; however, some data indicates that the warming trend has increased due to human activity.

The global warming is a phenomenon happening all over the earth, there are several causes, but most are a result of human activity. The graph in image 1 shows that a significant increase in the climate temperature in the mid-20th century, somewhere between 1900 and 1950. The industrial revolution happened between the years 1820 and 1840, although great improvements in technology were achieved in the 1900 's. The increasing temperatures since the industrial revolution work as a proof that global warming is a direct effect of human activity. As image 1 shows before the 20th century the variations in the earth 's climate were minimal, except for that of the ice age. Although the industrial revolution detonated the rising temperature due to the use of new chemicals, this change is not evident until it surpasses the previously registered temperatures in the mid-1900 's. Science and technology have improved in the last 200 years, most devices used to measure changes in temperatures were just developed about 150 years ago, so there is not much information of the temperatures before that (Vallis). Nevertheless, scientists have been able to estimate the earth 's temperature from millions of years ago by studding trees, fossils, sediments and water temperatures. Recent studies have proved how many man-made chemicals and activities have contributed to the climate change, affecting the natural processes in the earth like the

In the words of the great Herclitus “the only constant is change,” this is true regarding anything in life, including climate change. From our own experience, temperatures have been increasing year by year and snowfall has slightly diminished as the year’s progress. The portrayal of global warming by the media and the government has been over-exaggerated due to a lack of concrete evidence to back up their claims. Our planet shows evidence of climate change beginning approximately 4.6 billion years ago, when the earth was first formed. The Earth hasn’t been experiencing a constant rise in global warming, but an unpredictable change of warming and cooling periods. The media’s depiction of global warming does not exist, rather a pattern of unpredictable

The rise of air temperatures near Earth’s surface over the past century is known as global warming. Earth has experienced periods of gradual warming and cooling throughout its existence due to natural causes, such as volcanic eruptions and variations in the Sun’s output. However, scientists have created the idea of an increase in global temperatures to human cause, mostly the release of greenhouse gases into the atmosphere as a result of industrial industry. These greenhouse gases which absorb and trap heat emitted from Earth’s surface through a phenomenon known as the greenhouse effect.

Global warming is a worldwide epidemic that in large part is directly caused by human activities. NASA defines global warming as “the unusually rapid increase in Earth’s average surface temperature[…] due to the greenhouse gasses released as people burn fossil fuels.” In the past 100 years, global temperatures have been rising because of the increasing amount of greenhouse gasses being released into the atmosphere. Greenhouse gasses, such as CO2, are released when humans burn fossil fuels such as coal. People may argue that climate change is a natural part of life and has occurred in the

Global warming is an increase in the temperature of the earth's weather. Global warming is also known as the green house effect. Global warming is a very serious world issue. Most humans are trying to do as much as they can to help stop global warming. Global warming has caused many problems to the earth in addition to the humans that live here on the earth. A problem caused by global warming is very hot summers. Some summers have had days that the temperature had reached 30*C. Another Problem that global warming has caused is the melting of polar ice caps. Global warming caused the polar ice caps to melt which will cause the ice to break free as well as melt in the sea, sea levels all over the world will rise. Lastly,

Climate change is defined as “a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.” Climate change has happened as a cycle throughout history, with ice ages occurring, and then warming. The earth naturally warms and cools, but due to the burning of fossil fuels the rate is growing exponentially.

Global Warming is caused by various things. However the main causes is by human activities such as burning of fossil fuels, land clearing, agriculture, increased volumes of carbon dioxide and greenhouse gases are believed to be the primary sources of global warming in the past five decades. It has been recently predicted by global warming scientists from the Intergovernmental Panel on Climate that the average temperatures of the globe could possibly increase between 1.4℃ and 5.8℃ by the year 2100. This temperature rise can and will possibly affect planet Earth in many different ways.

The focus of this section is to explore natural climate change- which occurs without any human influence. These natural processes have been around for thousands of years and still operate and influence the planet today despite the presence of human beings. These changes have occurred over multiple timescales and will continue to alter our climatic temperatures in the future. There is no single cause of the switch in climatic changes as many factors affect the atmospheric temperatures. Changes can occur slowly or operate very quickly over a shorter time span and either resulted due to external or internal factors. External factors include any change in solar radiation, asteroid impacts, slow movement of continents or tectonic processes. Internal factors are those within the earth itself, such as ice-albedo feedback or increases in volcanic activity. Along with these various mechanisms, there are also positive or negative feedback. Positive feedback means that it amplifies the initial change. It does not necessarily mean it is warming nor does it mean it is

Though gasoline cars make lives of humans easier to travel, it threatens the environment. Climate is defined as weather conditions existing in a particular area over a period of time. When changes in weather patterns start to occur, this is called climate change. Peter Singer describes carbon emissions would extinguish human life. Climate change is a disastrous event because there is a wide range of environmental impacts affecting life expectancy. In different geographical areas, climates will change if temperatures influence them to fluctuate. The major cause of climate change is human expansion of the greenhouse effect. Kolbert presents scientific research about climate change and global warming leading to a global catastrophe. Any process that causes the Earth’s temperature to become imbalanced affects the climate. While climate change is a natural process, purchasing a SUV and doing human activities of all kinds has impacted on the atmosphere by burning fossil fuels for energy.

U.S. Conditions like Florida and other states with a high range of hot spells are perfect

Scientists have discovered 'climate forcing’s ' influence variations in climate systems and based on the depth and period of such forcing’s the adjustments to climate may be in a shorter or longer earth cycle. Natural forcing’s like variations in earth 's orbit, solar variation, volcanic eruptions and motion of tectonic plates have influence on the Earth 's climate

Deforestation, the cutting and burning of a forest, also increases the amount of carbon dioxide into the atmosphere. A NASA page says that “when a forest is cut and burned to establish cropland and pastures, the carbon that was stored in the tree trunks (wood is about 50% carbon) joins with oxygen and is released into the atmosphere as CO2. CO2, is, of

As the delicate balance of time moves on, slight differences in the weather can be noticed. Anyone can see that there is a shift in the balance of the environment; heat waves, hurricanes, tsunamis and the like are occurring faster than ever. Given the name of “global warming”, it is a problem on a world wide scale and only the cooperation of everyone can it be fixed or at least slowed down. With the heat of the Earth rising, national landmarks as well as complete ecosystems are fading out, and the only way to help stop this is to be aware of global warming.
