The Effects Of Global Warming On Our Planet 's Ecosystem

The Earth’s climate has continuously changed throughout history. Most of the time, these climate changes are attributed to small variations in Earth’s orbit, which in turn changes the amount of solar energy reflected onto the planet. However, according to NASA, the current warming trend is of such significance because “most of it is very likely human-induced and proceeding at a rate that is unprecedented in the past 1,300 years.” Essentially, what happens is that sunlight passes through the atmosphere and warms the Earth’s surface. This heat is radiated back towards space. Most of the outgoing heat is absorbed by greenhouse gas molecules and re-emitted in all directions, warming the surface of the Earth and the lower atmosphere. Human activities, such as the burning of fossil fuels, emit are increasingly emitting greenhouse gases into the atmosphere.

Global warming is “the gradual increase in the overall temperature of the Earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide and other pollutants” (Global Warming). The current climate changes that are occurring all over the world have sparked a growing controversy on whether global warming is indeed a result of human activity. Many of these individuals who play a role in this controversy argue that the current climate changes are simply part of the patterns seen in the Earth’s geological history or that it is simply caused by an increase in the brightness of the sun. This point-of-view is understandable as humanity is dependent on the climate for survival. However, many climatologists and scientists have found that the current climate changes are much more worrisome than previous climate changes. They have found that carbon dioxide (CO2) levels have increased over the years, because of an increase in the use of coal, oil, and gas, and that the Earth’s current pattern of warming is greater and faster than that of prehistoric warming episodes.

Today we are debating the important topic of global warming. As the affirmative team, we strongly believe that global warming is caused by the actions of humans. But this is not just a belief, this is a fact. Global warming, by definition, is a gradual increase in the overall temperature of the earth 's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants. The greenhouse effect is the trapping of the sun 's warmth in a planet 's lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet 's surface. In simpler terms, this means that the pollution

Global warming can be defined as the increase in the earth's sea level due to an increase in surface temperature. In decades past, there have been debates on what can be causing global warming. Greenhouse gasses and ozone depletion are one of the most important factors that geologists are facing in the fight against global warming. It presents a major problem for not only geologists, but also for policy makers, foresters, scientists, and most definitely the inhabitants of the Earth. Greenhouse effects consist of natural processes in which the temperature of the earth stays habitable. There are also many medical issues and health hazards that can harm humans, due to global warming and climate change. The ozone is also a major defense

Climate change is an issue that is occurring not only in Canada, but all over the world. Climate change has been caused by natural reasons, but due to human activities, it has quickened the process of climate change. Burning of fossil fuels and cutting down trees increases the amount of carbon being emitted, which would be trapped in the ozone. From 1948 to 2013, Canada’s average temperature has increased by 1.6°C. This increase of the average temperature has changed the temperature during winter and spring and will continue to significantly change over the course of many years. Climate change could lead to very severe impacts to different regions. It could cause extreme weather events like droughts, but also heavy rainstorms. Climate

In the past fifty years, the average temperature has accumulated at the fastest rate in recorded history (“Introduction”). Global warming is a rapid increase in the earth’s average surface temperature. Since the Industrial Revolution began in 1750, everyday human movements have contributed substantially to climate change by adding CO2 and other gases that trap heat into the atmosphere (“Causes”). The earth’s temperature has increased drastically over the past few years. One of the causes is the greenhouse effect. The greenhouse effect occurs when gases are released by people burning fossil fuels; this is changing the world’s atmosphere and temperature immensely. Fossil fuels contain overwhelming amounts of carbon dioxide which leads to the heating of the planet. Humans also have been cutting down trees which help turn carbon dioxide into oxygen. This helps contribute to global warming. Over the years, research has shown that climate change is caused by humans’ manipulation.

Society should be educated about the causes of global warming due to the way people are treating the environment. According to a continuous study done by N.A.S.A. the Earth’s global temperature has risen by 0.8 degrees Celsius, 1.4 if converted into degrees Fahrenheit, since the year 1880. Currently sitting at 14.82 degrees Celsius, predicted to rise another 6.4 degrees Celsius during the 21st century, human activities continue to add carbon dioxide into the air. Global energy all depends on how much is radiated from the sun and how much is released back into outer space. When humans over produce CO2 some of the energy is unable to escape, causing a greenhouse effect continually heating the globe. Global Warming, also known as the Greenhouse effect, is a problem everyone will soon have to face.

Humans have caused most of the past century's warming by releasing heat-trapping gases as we power our modern lives. Called greenhouse gases, their levels are higher now than in the last 650,000 years (LIVESCIENCE). The “greenhouse effect” is the warming that happens when certain gases in Earth's atmosphere trap heat. These gases let in light but keep heat from escaping,

Global warming is the warming of our planet at an extreme rate. The Earth’s climate has warmed by 7.8OC since 1880. (Quick facts about science, 2015). What causes global warming? The cause of global warming is the carbon dioxide. This acts like a blanket. Protecting the earth, and heating the earth. Sun rays would normally bounce around the earth, but with the blanket, the sun rays heat the blanket which heats the earth. (Petersen Science Text Book by G. Linstead, W. Clarke, 2015). “Of all the wealthy countries, we are probably the most vulnerable,” says Professor Will Steffen, executive director of ANU’s Climate Change Institute. “We’re locked into another 0.5OC temperature rise due to past emissions, but what we do between now and 2050 is crucial for the magnitude and rate of climate change later this century and beyond,” he says. (ABC, 2015) Figure 1.0 shows the percentage of carbon emissions being emitted into the atmosphere. Humans are contributing more and more to the amount of carbon dioxide being emitted into the atmosphere because every person now has a car and each car releases 9 kilograms of carbon dioxide into our atmosphere. Every factory has huge pipes, which are used to emit thousands of kilograms of carbon dioxide into our atmosphere. This is leading to the cause of global warming because carbon dioxide attracts heat from the sun, which acts as a blanket, like a green house. With the layers of

Global warming is a gradual increase of the overall temperature of the earth’s atmosphere, caused by the greenhouse effect. In natural circumstances the heat that is radiated by the sun should be re-radiated by the earth’s surface, whereby most of the heat escapes into space. However, increased carbon dioxide emissions and other air pollutants by humans cause more heat to be trapped in the

During the past century, human activities have released large amounts of carbon dioxide and other greenhouse gases into the atmosphere. Most of the gases come from burning fossil fuels to produce energy. Greenhouse gases, such as carbon dioxide, is absorb and emits heat into the earth’s atmosphere, keeping the Earth warm enough to support life. However, human activities, such as burning fossil fuels, are adding large amounts of greenhouse gases to the atmosphere. Greenhouse gases are like a blanket around the Earth, trapping energy in the atmosphere and causing it to warm. This is called the greenhouse effect and it is natural and necessary to support life on earth. However, while greenhouse gases buildup, the climate changes and result in dangerous effects to human health and ecosystems. People have adapted to the stable climate we have enjoyed since the last ice age which ended several thousand years ago. A warmer climate can bring changes that can affect our water supplies, agriculture, power and transportation systems, the natural environment, and even our own health and safety. There are some climate changes that are unavoidable and nothing can be done about it. For example, carbon

Throughout history the Earth has warmed and cooled time and time again. Climate changes due to subtle shifts in orbit, the atmosphere or surface, changing, or the Sun’ energy varying. Now the force that has the greatest influence on Earth’s climate is humanity. Human activity since the Industrial Revolution has affected the climate because the burning of fossil fuels has an impact on the greenhouse effect. The greenhouse effect is a naturally occurring phenomenon, but due to human activity there are increased levels of greenhouse gases. The increased levels, trap the sun 's energy and it warms the planet’s surface above the normal temperature. It’s the equilibrium of the incoming and outgoing of the sun’s energy that make Earth habitable, but now there is an offset because more is being trapped. The offset is global warming. Global warming is the unusually rapid increase in Earth’s average surface temperature over the past century, primarily due to the greenhouse gases released by people burning fossil fuels. The arctic places are primarily impacted by global warming and place that arose with the most concern is Alaska. Alaska is home to wildlife and human inhabitants. The main concern is that Alaska is melting and will continue to melt in the future. If Alaska continues to be affected by global warming, then there will be a large impact on the state as a whole.

Since the industrial revolution, scientists keep telling the story that the earth is not what most people might think back then: “a mother”, to be feared and respected. Instead, science today gives man godlike power; the earth is a machine, and we are its engineer, masters. We can change the earth like Lego blocks; we extract from it whatever we want to make use of, without needing to think about the consequences on environment, animals, or people. Humans caused global warming. With the economy that was built to deny any responsibility for the environment and cover up the truth behind their disgusting selfishness, it is hard to start fixing the environment when many people do not even believe a problem exists. I believe that it all came from the overwhelming power of the industry to lie and blind people from what is right there. Related to “Two Economies” by Wendell Berry, the economy that we have is an economy without value; I learned the lesson from history, nothing without value can survive as time goes on. Many may still believe in the industrial revolution but to me it is definitely the end of the world.

The issue of global warming should be on the list of our top priorities. Studies show that the average of global temperatures have risen since the Industrial Revolution began. Since the Industrial Revolution, human emissions has quadrupled the frequency of certain heat extremes and many scientists have warned that a failure to bring greenhouse gases under control could eventually lead to a 62-fold increase in extreme heat blasts (Gillis Justin A17). Most of the increase is due to human activities, especially the burning of fossil fuels and deforestation. These activities contribute to a build-up in carbon dioxide and other gases in Earth’s atmosphere. The Earth’s atmosphere is made of gases like nitrogen, carbon dioxide and oxygen. These gases act as a blanket that covers and gives us warmth, but once these gases such as carbon dioxide absorbs heat, but does not release it back into space in which causes the increase in global temperature. This is called the greenhouse effect because it only traps heat but does not release it.

science shows that is exactly the case. In a report in 2001, the Intergovernmental Panel on Climate Change stated, "There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities”. Global warming comes as a direct result of the greenhouse effect- the trapping of the sun 's warmth in a planet 's lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet 's surface. Our Earth is able to maintain a sustainable temperature because of the Greenhouse effect. Without it, the planet would be adverse and completely uninhabitable. The greenhouse gases water vapor, carbon dioxide, methane, nitrous oxide, and ozone are natural gases that are present in the atmosphere. They cause little to no harm when they are balanced but overtime humans have overproduced them, causing temperatures to rise and a heap of other problems. The imbalance of greenhouse gases is caused by the burning of fossil fuels, deforestation, decomposing organic matter, the use of fertilizer, and CFC’s. In this essay, I will first discuss the specific causes of Global warming, then I will address the effects, and finally detail how we as a society can help save our environment from further damage.
