The Debate Of Global Warming

We only contribute 3.5% of all CO2 in the atmosphere, while the other 96.5% is released by natural sources. There is no denying that global warming exists. Global warming is, unfortunately, a fact of our lives as humans, but humankind is simply not the cause. It is a natural occurrence and will continue to happen even after we are gone from the earth’s surface.

Global warming is a constant topic that is frequently discussed throughout the world. Many people including environmentalist, study this topic to determine the seriousness and world impact. The typical understanding of this concept “global warming” is known to be the total long-term intensification in the temperature present in the atmosphere (3). When discussing this topic, it is still important to consider the fact if Global Warming is actually fact or fiction. In order to evaluate this controversial issue, one would need to discuss evidence for or against the idea of global warming. To further discuss this topic, one should evaluate valid sources that can support one’s conclusions.

The globe is being rocked by extreme weather and the hottest temperatures on record. As the average global temperature soars, there are floods, droughts, unusually cold winters, forest fires, and huge storms. Are all of these horrors being caused by human-induced global warming?

The essay “The Climate emergency” is based on a speech made by Al Gore at Yale University in April 2004 to a room full of students. Al Gore is the former Vice President of the United States under President Bill Clinton. He is also an environmental rights activist. In the beginning of the speech the former vice president shares a story about his trip to a Shoneys Restaurant with his wife Tipper to draw the audience in. (300-301). Once he captures their attention he is able to focus them on his real message.

Botkin assures his readers that evidence that global warming ill produce negative effects on the planet is very weak. He too presents scientific data to support his

For example, Nancy Nocare said: “ In the past 2000 years, we have seen the Roman Warm Period (warmer than today), the Cooler Dark Ages, The Medieval Warm Period (at least as warm as today), Little Ice Age ( that drove vikings out of Greenland) and most recently, a gradual 300 year warming to the present day. (many changes and none of which were caused by humans)”. Also, Over and over again, within virtually any time frame, we find the climate changing, for reasons we do not understand. Although, something we do know is that there are many more factors in play than simply the concentration of Co2 in the atmosphere. Factors such as, the shape and size of the Earth’s elliptical orbit around the Sun, activity from the sun, as well as the amount of wobble and tilt in the Earth’s axis among many others. She said: “Yes, using fossil fuels for energy has a side effect—increasing the amount of CO2 in the atmosphere. Okay. But what about the upside? In the case of fossil fuel that upside is enormous: the cheap, plentiful, and reliable energy that makes modern life possible, and at a scale no other energy source can match. The latest trend has been a warming one, but it began nearly a century before there were significant carbon dioxide emissions from burning fossil fuels. Also, there been no significant warming trend in the 21st century.

Another point Brian Sussman made was, since the little Ice Age global temperatures have risen only one degree and most of that occurred before 1940. According to data from NASA’s temperature record, the surface temperature on earth has increased since 1880 and leveled off between the 1940s and the 1970s. That would make sense, because the industrial revolution began around the 1880s. Also, in the last decade, our global temperatures have risen to the highest levels ever recorded. This information makes me lean toward the man-made side of the global warming argument.

Damon Matthews, a professor in Concordia University’s Department of Geography, found a direct connection between carbon dioxide and global warming. Matthew’s studies show that same global temperature increase, regardless of when or over what period of time the emission occurs. The effect of adding more carbon dioxide is predicted in the theory of greenhouse gases. Swedish scientist, Syante Arrhenius, first proposed the theory in 1896, based on earlier work by Fourier and Tyndall. At the same time, many scientists have reached the same conclusion. If we increase the amount of greenhouse gases in the atmosphere, the Earth’s temperature will increase. Energy is absorbed from the sun in the form of visible light and ultraviolet radiation. The earth then releases some of this energy as infrared radiation. Greenhouse gases in the atmosphere captures some of this heat, then re-emit it in all directions. During this process, carbon dioxide and other greenhouse gases keep the Earth’s surface 33 degree Celsius warmer than it would be without them. According to an ongoing temperature analysis conducted by a scientist at NASA’s Goddard Institute for Space Studies (GISS), the average global temperature on Earth has increased by about 0.8 degree Celsius. Since 1975, two-thirds of the warming has occurred at a rate of roughly 0.15-0.20 degree Celsius per decade.

Climatologist Tim Ball argues this point in his article, The Science Isn’t Settles – The Limitations of Global Climate Models. Dr. Ball looks at the data of global temperatures and concludes that the earth’s atmosphere is actually cooling while in its cooling cycle, which is the complete opposite to the assumption that the atmosphere is heating up. In 1999 a petition was asked the U.S. Government to reject the environment treaty The Kyoto Protocol, which was signed by over 17,000 other scientists sharing the same views. These scientists view that there is no convincing scientific evidence around the idea of global warming and all of these conclusions are not justified. They believe that the human release of CO2 and other greenhouse gasses are not contributing to global warming and the climate change, instead the increase of CO2 is promoting plant and animal growth. Some other scientists argue that global warming is being blown way out of portion and its effects are so small we will not notice its effects. They believe this increasing in extensive publicity is an environmentalist scam for more recognition, power, and

Since 1975, the surface of the earth 's average temperature has risen by 0.9 degrees Fahrenheit; global warming caused by greenhouse effect has become the focus topic of the world. It has long been recognized academically that due to the burning of coal, oil, natural gas and so on the carbon dioxide is the main culprit of global warming. I watched a documentary, which called “The Great Global Warming Swindle.” In the documentary, the scientists pointed out that there is no direct evidence that carbon dioxide is the cause of global warming, global warming is more of propaganda, a kind of political activity. Normally, as an amateur people, should write this article emphasizes their neutrality, but actually, I agree with BBC.

Polar bears sweating, the Earth reforming into a volcano, and oxygen artificially supplied to the atmosphere is the future of tomorrow. It is unfortunately a consequence of our activities today. Global warming is an extremely adverse word and a great deal of controversy. It is all an interconnected process of globalization, hence having human activities cause global warming and destruction of the environment.

However, it is the argument that is against human activity being the primary cause of global warming that provides a superior explanation to this currently unknown global phenomena we call global warming. Despite the overbearing support against this argument, there is too much factual evidence about the complexity of the atmosphere and all of its elements that outweigh the predictions being made and then amplified significantly. Using supporting facts leads to a superior argument than using mathematic estimations, which consistently fail to meet their expected results. The changes in climate, including temperature change and rising sea levels, have all been happening for thousands of years providing historical evidence to show this change in climate as a natural occurrence. The most critical aspect of the argument is that rising levels of atmospheric CO2 do not necessarily cause global warming, which contradicts the core thesis of human-caused climate change as stated in a publication made on ProCon.org where the director of Greenpeace International Patrick Moore spoke on the relationship between the CO2 emissions from human activity and global temperature. He states that "there is some correlation, but little evidence, to support a direct causal relationship between CO2 and global temperature through the millennia” (ProCon.org). It is important to acknowledge that regardless what the actual

The first argument many individuals would make against global warming is that the current climate changes are simply part of the cycles seen in the earth’s geological history. Global warming would easily be proven correct if Earth’s temperature had been stable for the majority of its geological history. However, for over two million years, during the Ice Ages, Earth’s temperature rose and fell

The concept of global warming has become one of the most widely debated and controversial topics of our time. Scientists learned long ago that the earth’s climate has powerfully shaped the history of humanity. However, it is only in the past few decades that research has revealed that humans have a significant influence on the climate as well. A growing body of scientific evidence indicates that since 1950, the world’s climate has been warming, primarily as a result of emissions from the burning of fossil fuels and the destruction of tropical forests. More importantly, an article titled "Global Warming" published in the New York Times shows that methane, a gas that is emitted from landfills, livestock and oil gas facilities,

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.
