Recommended: Causes of global warming
What is blue, green, and sustains an environment for living organisms to live? The answer is Earth; the planet of life where plants, animals, and humans breathe in the oxygen that comes from the atmosphere; knowing that we depend on oxygen to survive, preserving the atmosphere should be important enough to take care of it; sadly Earth is going through a global problem that is putting the atmosphere and the whole Earth in danger; that problem is called Global Warming. Global warming is used to describe increases in the average temperature of the Earth’s atmosphere and oceans; therefore this change is believed to be rapidly changing the Earth’s climate. Global warming not only changes the atmosphere, it changes the agriculture, energy, insurance …show more content…
Natural causes are Earth’s orbital tilt, which varies between 22 to 25 degrees around every 41,000 years which could cause the atmosphere of the Earth to fluctuate and temperature to rise. A natural cause of global warming is volcanic eruptions from volcanoes which release huge amounts of carbon dioxide, dust and debris into the atmosphere. Another natural cause is the sun’s activity which increases the planet’s temperature through sunspots and solar flares. According to Nathan Brown, “Solar radiation levels can have some impact on the Earth’s climate” (Brown). As radiation levels vary towards Earth, Earth’s climate changes and it affects the resources, environment and atmosphere. In the article, Global Warming, Global Warming, “When the Sun’s energy is at its peak, temperatures in both the lower atmosphere and the upper atmosphere become warmer” (Global Warming, Global Warming). As the sun’s energy raises so does the atmosphere temperature which allows for the change of weather on the planets in atmosphere. Wetlands and swamps release methane into the atmosphere which allows for trapping of the sun’s heat in the atmosphere which leads to global warming. Natural causes of global warming allow for glaciers, ice caps to melt, which can lead to rising sea levels which threatens the sea levels near the coast. In the article, Natural Hazard, Global Warming, “Water vapour in the form of clouds can either cool the Earth’s surface by blocking the sun’s rays, but can also increase the temperature of the Earth’s surface by acting as an insulating blanket” (Natural Hazard, Global Warming). Water vapour is one of the natural causes that happen when clouds are formed and it can either help relieve the global warming process or it can harm the atmosphere and increase global warming. These are the reasons natural causes affect global warming and how much it increases the temperature of the
“The modern form of the word environment comes from an older word that we hardly use anymore: environ, to surround, to form a ring around, to encircle” (Stoll 3). The meaning of the word environment did not become a major factor in the lives of humanity until 1945. The tragic events that led to the end of World War II sparked a chief movement in history: American Environmentalism. Global decision-making changed as well as human unity due to the mere purpose that fate of all people and the environment became intertwined (Stoll 1). I will further discuss the dramatic attempts made by some Americans to bring the importance of preserving our environment to the surface to show if and how we have evolved.
When the sun heats the Earth gases are released as well as water vapor. They go into the atmosphere and regulate the temperature. This is known as global warming or the greenhouse effect. Many of the environmental complications derive from the political and social involvement. The climate was not the only cause, but we had humans played a role on what had been occurring to the world. Earth has many different atmospheric layers that are influenced by the greenhouse gases. “Atmospheric concentrations of carbon dioxide have now increased nearly 30 percent since the beginning of the Industrial Revolution; methane levels have more than doubled; and nitrous oxide concentrations have risen by about 15 percent” (Fagan 209). The increase of these gases also enhanced the trapping of the heat. With more heat being trapped this lead to many coastlines to flood due to the melting of snow and ice. The increase of dangerous weather actions will pose as a threat also. These changes in the environment would eventually lead to political and social change of the people Overpopulation in certain areas and industry formation influence the greenhouse effect. We as a whole are destroying the place we live, the natural world. Although there are ways to prevent and reduce global warming, we cannot stop the natural occurrence of future climate. Climate is not the only factor, each individual that as
Firstly, global warming is said to be caused by the high levels of carbon dioxide released into the atmosphere by humans. Smoke produced by factories, vehicular exhaust, and the burning of fossil fuels such as coal in power plants are the primary sources of carbon dioxide. The theory is that carbon dioxide being released into the Earth's atmosphere is steadily building up because it cannot escape into space. The theory as to why the carbon dioxide in the atmosphere actually causes the Earth's average temperature to rise is outlined as follows:
The climate on the Earth is changing. Ice age is interleaved with the global warming. In the present age, the temperature of the Earth's climate system continues to rapidly increase and it leads to global warming. Global warming is the process of gradual growth of average annual temperature of the atmosphere of the Earth and World oceans. The average temperature on the Earth was increased by 0.6C. There are various reasons for global warming, such as human activities, natural events, increasing of gases, such as carbon dioxide in atmosphere and solar activity (Global warming).
The article “an introduction to climate change” describes in detail about the causes of climate change, and its potential effect on earth. According to this article, the global warming is due to the accumulation of carbon dioxide and other pollutants formed from burning fossil fuels that accumulate on earth’s atmosphere so that light rays are reflected back to the earth surface causing the atmospheric air to heat up. In addition, the article also gives some relevant solutions to global warming such as reducing air pollution and use of “clean energy.”
STATE THESIS & MAIN POINTS: I’m going to persuade you that going green is one solution you could do to help improve the environment by first explaining the problem, then by explaining the factors responsible for pollution, and lastly by listing ways that can help solve this problem.

Scientists have begun to say that we have to do more to protect our ecosystem, because our very existence is depending upon it. When the ecosystem is not functioning properly the continuation of plant, animal and human life ecosystems would be impossible. Life cycles can not function without ecosystems. The ecosystem provides us with clean air, water, habitats for fish and other services. They also aid in the mod...
Climate change is evidenced through shifts in the weather patterns such as winds, humidity and temperatures over certain durations. Natural climate changes occur less frequently and they are triggered by factors related geographical aspects as well as solar radiation. The earth’s movement on the orbit triggers changes in climate causing some areas to have higher temperatures than usual while others are significantly cold depending on the position of the earth on the orbit. The heat form the sun causes changes on the stratospheric ozone and it increases the amount of greenhouse gases. Heat from the oceanic crust also contributes to warming as a result of episodic hydrothermal venting (Liao & Sandeberg, 2012). Volcanic activity also causes a release of certain elements that may block the sun and also contribute to increase greenhouse gases in the atmosphere.
This is based upon the sunlight and volcano eruptions which plays an extreme factor. "Most often, global climate has changed because of variations from sunlight. Tiny wobbles in Earth’s orbit altered when and where sunlight falls on Earth’s surface. Variations in the Sun itself have alternately increased and decreased the amount of solar energy reaching Earth. Volcanic eruptions have generated particles that reflect sunlight, brightening the planet and cooling the climate. Volcanic activity has also, in the deep past, increased greenhouse gases over millions of years, contributing to episodes of global warming." (Global Warming, web.) However, I firmly believe that climate change is not only the result of natural causes alone. I think it is man-made and the major factors are from CO2, factories, and power plants burning coal/ oil, natural gas.
Global Warming is a condition caused by greenhouse gases and human activities. The increased concentration of greenhouse gases due to activities such as deforestation and fossil fuel burning is causing the Earth’s atmosphere and oceans to warm up. As a result of this, global warming has some serious effects in the shape of extreme weather, species extinctions, and rising sea levels. These effects can contribute to the changes that are taking place all over the world, most of which are dangerous enough to pose a threat to the survival of life on Earth in the future.
There needs to be a reduction if not extinction with the increasing amounts of carbon dioxide, methane, chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), per-fluorocarbons (PFCs) and nitrous oxide into the atmosphere because it is directly affecting global warming. The combustion of fossil fuels and greenhouse emissions mainly contribute to the increase of these gases. The longer we go without solving this global problem the more conflicts we will have in the future. Although global warming does make the earth warmer there is more to worry about than heating to death. Major concerns revolve around effects on agriculture, water resources, ocean level and coastal regions, and disease. Many scientists and experimenters still disagree with global warming using excuses such as ‘primitive’ climate models, which predict global warming trends, can not accurately simulate the Earth; it is too difficult because there are thousands of variables to consider. With the issue of global warming alternative sources of energy are looked for. “Data indicates that hydrogen is [the] only suitable future fuel.” (Williams, 102). Many scientists agree, but how long will it take for us to get there?
As Robert Frost once said, “ Some say the world will end in fire, some say in ice. From what I’ve tasted of desire I hold with those who favor fire.” This excerpt can relate to the idea of global warming. Global warming can be defined as an increase in the earth's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. During the past 10,000 years the earth has been in an ever-growing cycle that has significantly changed the climate. These changes are becoming more prevalent in our world today in the past 150 years. Scientists have been analyzing the causes and effects of the greenhouse effect and many other issues that global warming has presented. As John Houghton states in his book, Global Warming the Complete Briefing, on page 2 “ The 1980s and 1990s were unusually warm. Globally speaking, the decades have been the warmest since accurate records began somewhat over a hundred years ago and these unusually warm years are continuing into the twenty-first century.” There are countless records that show that our world as a whole is getting warmer, and the facts cannot be disputed. Everyone in the world today is experiencing the effects of global warming. These effects might be small now, but if we don’t protect our planet now then the consequences will greatly be increased.
Climate changes occur in our earth's atmosphere due to a buildup of greenhouse gases. Greenhouse gases can occur naturally as well as a result of human activities. The greenhouse gases are carbon dioxide, methane, and nitrous oxide. “Carbon dioxide is released into the atmosphere when solid waste, fossil fuels, and wood are burned.” (2) The gases help to warm the surface of the Earth. Each greenhouse gas absorbs heat differently. If natural gases did not occur, the temperature of the earth would be considerably cooler. “Problems can occur when higher concentrations of greenhouse gases are present in our atmosphere because they have enhanced our earth's heat trapping capability.” (3)
Scientists blame the greenhouse gas effect in combination with societies greenhouse gas emissions for the rising temperature. The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions. Since part of this re-radiation is emitted back towards the earth’s surface and the lower atmosphere, it results in an elevation of the average surface temperature above what it would be in the absence of the gases (Intergovernmental Panel on Climate Change).
