The Warm Blue Dot : Evidence For Anthropological Global Warming

Does the high level of Carbon Dioxide (C02) possibly harm the Earth’s planetary biosphere, or has it already done so; in fact, many worldwide scientists have protested that the Earth is at its ‘tipping point’ but no efforts have been adapted to save the biosphere? A support of this controversial topic; congressional meeting and testimony, is from one of the top U.S. climate scientists, James Hansen to Former Vice President Al Gore, with an emphasis on the cause of C02. Beyond the ozone layer is atmospherically holey, Earth’s temperature is rising, and the climate changing conversely, one that people trivialized the most is: Global warming. Increasingly, subject to concern not only via online discussion, magazine and

The Great Warming is a book written by Brian Fagan that encompasses the environment and history pertaining to most of the human race between A.D. 800 and 1300. Not only does the book give a new dimension to world history by looking at climate history, but it also provides the reader with an ominous warning of the impact that climate change may have on the human race in the future. Fagan references many civilizations in the book that were affected by the rise in surface temperatures. He goes in depth with them individually to show just how worldwide this climate change was, how each civilization adapted or failed to adapt, and who the winners and losers were during this medieval warming period.

Scientists have given numerous warnings that human-caused, or anthropogenic, climate change is not only occurring now, but accelerating more quickly than predicted (Maibach, Myers, and Leiserowitz 295). Global warming contributes to climate change as a result of the release of greenhouse gases into the atmosphere (“Global Warming”). The level of greenhouse gases like carbon dioxide, methane, and nitrous oxide in the atmosphere has increased significantly over the years. Patterns of warming are sufficient to conclude that this increase has coincided with the start of the Industrial Revolution (“Global Warming”). By analyzing carbon dioxide pockets that have been trapped in Antarctic ice, scientists can assuredly confirm the correlation between recent warming

The Earth 's atmosphere has changed all through history. Just in the most recent 650,000 years there have been seven cycles of frigid progress and withdraw, with the sudden end of the last ice age around 7,000 years back denoting the start of the present day atmosphere period and of human development. The greater part of these atmosphere changes are credited to little varieties in Earth 's circle that change the measure of sun based vitality our planet gets. Exploratory proof for warming of the atmosphere framework is unequivocal. The present warming pattern is of specific criticalness in light of the fact that the vast majority of it is likely human-impelled and continuing at a rate that is exceptional in the previous 1,300 years. Earth-circling satellites and other mechanical advances have empowered researchers to see the comprehensive view, gathering a wide range of sorts of data about our planet and its atmosphere on a worldwide scale. This group of information, gathered over numerous years, uncovers the signs of an evolving atmosphere. The warmth catching nature of carbon dioxide and different gasses was shown in the mid-nineteenth century. Their capacity to influence the exchange of infrared vitality through the environment is the logical premise of numerous instruments flown by NASA. There is no doubt that expanded levels of nursery gasses must bring about the Earth to warm accordingly. Ice centers drawn from Greenland, Antarctica, and tropical mountain icy masses

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.

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.

Global warming has been a major concern and has greatly affected the environment around the world for years. Andrew Revkin stated in a New York Times article entitled “A Closer Look at Climate Panel’s Findings on Global Warming Impacts” that climate change throughout the 21st century will lead to increases in ill-health in many regions, as compared to a baseline without climate change. There have been a number of debates regarding this controversial topic, though most of the scientific community can recognize the existence of global warming. Many often question if this effect on the environment is caused by human activity or natural cycles. About 95 percent of scientific studies prove that global warming is essentially caused by man.

The Great Warming by Brian Fagan claims that environmental changes (most commonly prolonged droughts, El Niños, and La Niñas during the Medieval Warm Period) affect human civilization, including human’s trading abilities, overall movement, and quality of life. He examines the world’s ancient climate warming, known as the Medieval Warming, between the 10th and the 15th centuries, also mentioning the preceding and succeeding centuries. Fagan gathers his research using studies conducted by archaeologists, historians, and paleoclimatologists. Throughout his book, he refers to direct methods to study climate change, such as instrument records and historical documents, and indirect methods, such as ice, deep sea cores, coral records, and tree rings. Fagan digs into the rise and fall of multiple civilizations around the world as an effect of The Medieval Warming Period. As well as examining civilizations across the world, he attempts to connect the climate change patterns during The Medieval Warming Period to the current global warming faced today. The Great Warming discusses positive and negative connections between climate change and human civilizations across the world, starting in Europe and working its way into Asia, North America, South America, Africa, and even covering the arctic ice caps; however, throughout the book, Fagan has a hard time connecting his various ideas back to one main topic and can easily stray from his point about the effects of climate change.

Climate change or colloquially known as global warming, now pose a new threat to civilization as the levels of greenhouse gases (GHG) are soaring to new levels. The most significant contributor to greenhouse gasses would be Carbon Dioxide (Co2). The levels of Carbon Dioxide (Co2) gas have risen to levels civilization has not seen before. As such, the effects of these levels are not known to civilization as data gathered from the ice cores drilled in the Antarctica only shows data up to 650,000 years ago. However we can conclude that present CO2 concentrations are higher compared to any time in the last 650,000 years (IPCC 2007). Current carbon dioxide concentrations are hovering around 389 parts per million (ppm) as of September 2011,

A second study states “Although some records are available from the 1600s and 1700s , systematic measurements of climate began in the mid-1800s. The data include measurements of surface temperature over land and the oceans, precipitation amounts, sea-ice extents, and global sea levels. Since the 1970s, satellite studies have provided additional data on temperature trends at Earth’s surface and through the layers of the atmosphere” (“Global Warming- Britannica”). The second source backs up the first source with exact quantitative data about changes in the first. (See pictures on page 6-7 ). The first topic of the United Nation’s Climate Change 2014 Synthesis Report is “Observed Changes and their Cause” which states “Each of the last three decades has been successively warmer at the Earth’s surface than any preceding decade since 1850” (“United Nations” pg 7). These three sources prove, through scientific observational facts, that the climate of the Earth’s surface is changing very rapidly, therefore, proving that through conclusive science the topic of climate changer is accurate.

Current data reveals that the concentration of Carbon Dioxide in the earth's atmosphere is approximately 387 parts per million, which is roughly a 31% increase in the period 1750 to 2009. Consequently, it is evident that such increases in temperatures have caused a warmer planet (7). It is also evident that it is impossible to reverse the developments of industrial revolution. This means that as the advancements of industrial revolution continue and as energy demands increases, it is possible that this trend of climate change will continue for decades to come (McAloon, 8). The consent of the climate research community is that it most likely already affects climate noticeably and will compel significant

In the last 100 years, Earth’s average temperature has risen by 1.4°F. The rising global temperatures have caused changes in weather and climate. Global warming refers to the ongoing rise in the average temperature near Earth’s surface. This is causing a climate change, which refers to any significant change (major change in temperature, precipitation, or wind patterns) in the measures of climate lasting for an extended period of time (several decades or longer). Due to this, it is projected that the temperature will rise from 2 to 11.5°F in the next hundred years (US EPA, 2014). The “drivers,” which are the principal causes making this occur, are very controversial. It is debated whether a change in temperature is due to the work of

In the 1960s, the warming effect of carbon dioxide gas became increasingly convincing. Scientific opinion favoured the warming viewpoint ever more during the next decade. And by 1990s, improved computer models and observational work confirmed that greenhouse gases were deeply involved in most climate changes and human-caused emissions were creating evident global warming (“A Brief History of Climate Change”).

Over the course of this class we have discussed the importance of climate change and the different factors that either help or harm the climate in different ways. We have discussed greenhouse gases, changes in earths orbit around the sun, and the fluctuating changes in the environmental temperature. Earth’s climate was healthier, cleaner, and possibly even warmer in past history. Climate change is not caused by any individual and not just changed on a whim, climate change occurs naturally. Human existence has contributed to the increase of global temperature and also the increase in the build up of CO2 in the atmosphere. Chapter 1 in the book states, “Unintended byproducts of agricultural, industrial, and other human activities can influence climate. Anthropogenic forcing occurs mainly by the way of additions of CO2 and other greenhouse gasses to the atmosphere”. Even though Earth’s climate did change well before humans were brought into existence, humans are exacerbating the condition of the climate with all the CO2 concentration that is being used everyday by things you might not see as being harmful. This paper will discuss the history of climate change throughout the years, the human affect, and what individuals can do to help the environment, along with what actions the government can take to lessen the climate from changing.

Have you ever wondered what could possibly be causing the change in our temperature? This essay delves into the meaning of climate change along with the human and natural processes that alter the globes atmospheric temperatures over a long period of time. It includes various mechanisms and feedbacks, the history of climatic change, human roles/impacts, as well as my own position on the subject.
