Climate Change, or “Global Warming,” has been a point of argument for many years. There are many theories for how and why the climate has changed and been affected. The big question is, Are humans really causing the climate to change or is it some other cause no one is willing to see? All around climate change or “Global Warming” is a cycle of the Earths atmospheric temperature, because statistics show that this cycle has been occurring for millions of years. There is no direct evidence supporting the claim that humans have any direct effect on global warming. The IPPC, Patrick Gonzalez, and Bharat Raj Singh have been giving people hand-picked information on climate change to control what we think. The people need to have all the information in order to make a sound decision on how they feel. There is yet be any discovery and scientific proof of what is actually causing global warming. There are a couple well known arguments that can be really convincing that humans are the cause. According to Gonzalez, the first is that through deforestation, humans have taken a key pathway that greenhouse gases are removed from the atmosphere. The second argument is that the industrial This statement is utterly untrue and can in no way be scientifically proven. The IPPC claims that there will be a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century (Many Climate Impacts Predicted by the IPPC Are Already Happening). This is a statement that brings much skepticism the winters are still cold and the news just the other day was saying that the country was experiencing record lows for this winter. The average global temperature has not increased since 1995 and has decreased since 2002 (Global Warming: Ten Facts and Ten Myths). So far it has been scientifically proven that the average global temperature has not
First, during the last few decades the Earth is experiencing greater rate of rising temperatures due to greenhouse gases that are being produced by human activities rather than because of environmental reasons, such as solar or volcanic activities. In 2006 the President of the National Academy of Sciences stated: “There is no doubt that the Earth is warming,” also he added that people are at least partly responsible for these changes in addition to regular factors (Cicerone, par.4). Natural factors have produced climate fluctuations on Earth for several million years. People have effected an atmosphere of the Earth just for nearly one hundred years, since Industrial Revolution has begun (Revkin 340). Of course, it is unfair to say that global warming is caused entirely by humans. For example, people can not have an impact on the position of Earth in relation to the sun, or on the galactic density, or such nature events as air emissions of volcanic gases. As a result of these environmental factors, Earth usually had higher rates of temperature fluctuations during the previous million years than it has in later centuries. On the other hand, people are responsible for the highest concentration of greenhouse gases during the last 650,000 years in the atmosphere due to industrial manufacturing, driven by the increase in consumer consumption (Lindsey, par.
Global temperatures have noticeably been rising since the mid 1800’s.The average temperature has increased by 0.6 ± 0.2°C since 1860 according to (John Sweeney, 2003)with accelerated warming apparent in the latter decades of the 20th century. The legitimacy of global warming had long been debated, however in a report by (IPCC, 2007) it states that warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice and rising global average sea level. Simulations on models such as EC-Earth provide us with predictions for future climate change. Depending on levels of emissions an increase of 1 to 5.5 degrees celsius is expected in average global temperatures by 2100.
Ever since the advent of weather observation and prediction technology in the past 150 years, science has created a consensus that the earth is getting warmer, and that human influence is to blame. Some even blame this change, known as global warming, for bouts of extreme weather including cyclonic storms, droughts, wildfires, and heat waves. These scientists (and much of the public) believe that our influence is the problem, as our emissions of carbon dioxide and other greenhouse gasses, the product of the usage of our fuels, are polluting the atmosphere and trapping energy from the sun within. However, a minority group, scientists and public skeptics alike, believe this warming trend is merely a coincidence with the earth’s naturally cyclical climate, and that the activists are overstating something they know little about. Many even agree that if the prospect of our influence were to be true, the effects are not at all that bad, unlike what it is hyped to be. Thus, global warming has become a debatable theory. Much like legislation that prevents schools from teaching evolution as anything more than a theory, now there are also laws that mandate that global warming be considered debatable, and to argue both sides of it (Jonas).
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 Earth's climate has changed significantly throughout history. In the last 700,000 years there have been seven cycles of glacial advance and retreat. With the abrupt end of the last ice age approximately 7,000 years ago the beginning of the modern climate era was born. In the last century the global sea level has risen 17cm. All three major global surface temperature reconstructions show that Earth has warmed since 1880. Most of this warming has occurred since the 1970s, with the 20 warmest years, having occurred since 1981 and with all 10 of the warmest years occurring in the past 12 years. There is no denying global warming. Once considered a conspiracy theory by the world’s leading governments, industries and populations; global warming
For a majority of people, it isn’t new news that the Earth’s climate is changing and increasingly getting warmer. For quite some time now, people have been arguing about what the actual causes are and what role humans have played in the current condition of the earth. A good bit of people seem to be in agreement that due to the actions of humans, the earth’s climate is increasingly getting worse and that if things don’t change, than everyone living on earth will be facing the consequences. However, this is not entirely true. The fault of climate change does not fall solely on the shoulders of mankind, but on the earth as well.
Climate change has been nothing, but controversial in the last fifty years. Climate change is a change in the average weather of a region or city. Scientists have opted to use the term "climate change" instead of global warming because as the Earth's average temperature changes, winds and ocean currents move heat around the globe in ways that can cool some areas, as well as warm others. There is an ongoing dispute about the effects of humans on the global climate and about what policies should be implemented to avoid possible undesirable effects of climate change. Ninety-seven percent of published scientific research concluded that climate change is real, problematic for the planet, and has been exacerbated by human activity. But what about the three percent that contradicts that?
The “Child in the Basement” by David Brooks discusses an analogy. It is “a critique of American moral life.” Its basic themes are scapegoating, morality and duality of human nature, along with political ideology, this fiction story, covers the ideas of “ what happiness is? And what is the cost of happiness whereas the film “I Am” focuses on two practical and provocative questions: what’s wrong with our world, and what can we do to make it better?
Our world is always changing, so is our climate. Some changes are apparent, others not so much. Climate change is an important issue of concern in the twenty-first century. Environment, if it changes at all, evolves so slowly that the difference cannot be seen in a human lifetime (Wearth, 2014). Mostly all scientists predicted that it would take thousands of years for the planet to warm up due to emissions of carbon dioxide from fossil fuels called greenhouse gases. But in the past 200 years, things began to change. The rate and the amount of warming that is happening on this planet are unprecedented. Wearth says, “People did not grasp the prodigious fact that both population and industrialization were exploding in a pattern of exponential
Humans have caused global warming by doing many things but the main three are burning of fossil fuels and green house gas emission, deforestation, and excessive use of chemical fertilizers. Global warming is like a bad dream going worse.
Climate change is a long-term change in regional or global climate patterns. From the mid twentieth century to now, it has mostly been about a significant increase in average global temperatures. Climate change is a major issue in the world today, and a lot of people feel very differently about the cause of it. The common argument about it is whether climate change is a natural occurrence or if the recent increase in temperatures is because of humans. Climate change is a natural cycle in the Earth’s weather. Before humans started burning fossil fuels, there were still weather cycles on Earth that were as hot or hotter than what it is now. In fact, Earth’s weather now, is on pace with the previous weather patterns in history. Human emitted
The Earth is currently locked in perpetuating spiral of climate change. While the global climate has unarguably been changing since the dawn of it's manifestation, the once steadied ebb and flow of climate change has become increasingly more unpredictable.The risk of rising sea levels, and drought plaguing the fresh water supply, during the time that flooding and sporadic storm conditions turn once fully inhabited regions into uninhabitable death traps. Climate change catalyzed by human's increased production of carbon dioxide, is more noticeable than ever in our recorded history (United States, 2014 National Climate Assessment). Thankfully however, with the changing weather conditions due to carbon related emissions, the change in public opinion about their personalized influence on climate change is also increasing. Kevin Liptak Jethro Mullen, and Tom Cohen note that In reaction to the most recent governmental report on climate change, even the U.S. government believes that a stronger approach needs to be taken to correct our self-generated cataclysm.
The hottest recorded temperature was in 2005 which matched the temperature in 1998. Twice in the last decade we've had the hottest temperature on average ever recorded throughout history. Coincidence. I think not. The snows of the Kilimanjaro have basically vanished and in a couple decades Glacier National park is going to need a new name because by 2030 there will be no glaciers left in the whole park. The great Greenland icecaps are melting at an alarming pace, and sliding into the sea. Your right, who cares it's not like its happening near us. But by 2100 all our coastal states will look like Venice including ours. You won?t be alive but your children and grandchildren will. The sea level is expected to rise up to 23 inches in the next decade. There has been a 100 percent increase in intensity and duration of hurricanes and tropical storms since 1970 according to a 2005 MIT study. How much more evidence do we need before someone does something about this? For anyone who cares at all about the future, the gradual transformation of our earth is turning into a human-furnace that makes terrorism look like a game of monopoly. Think I'm kidding? By 2050, 15-37% of all plant and animal species could be extinct. Meaning it will be harder for plants to produce photosynthesis. No big right? Wrong. Without photosynthesis, oxygen can?t be made. Most of us in this room will be in our late 60?s by then with children and grandchildren. What does that mean for them? The air will be harder to breath and the temperature of earth will have increased by 2 degrees Fahrenheit. By 2050 up to 38% of water will be unable to hold underwater species because of rising temperature.
Global warming has become on of the most controversial issues in the media today. While most of the Western world countries have generally accepted the premise that man's chemical emissions in the atmosphere can and are affected by the world’s climate patterns, in the United States, the issue has become so politicized with many republicans challenging the science behind the theory. Global warming is a greenhouse effect whereby gases are trapped on the earth’s surface causing it to heat up (Maslin 14). It is based on the worldwide temperature records that have been maintained by human beings through their activities since the 1880,s. In addition, global warming is not only caused by human activities only but also through climate changes in solar radiance. The problem is that, humans continue to contribute to the global warming phenomenon. All citizens should work in reducing human activities that cause global warming and also support the development of nuclear power. Scientists deem that, global warming is mainly caused by human activities which accelerate the natural process by creating greenhouse gases in the atmosphere. Human activities have become a great contribution to the greenhouse effect and this means that climate changes are inevitable. They further argue that, if these activities continue and are not reduced, it will lead to more trapping of energy radiated from the earth and this will likely lead to extreme weather and global warming. Global warming should be at reduced levels or else, it will be catastrophic.
Global Warming One of the most substantial problems in the world today is global warming. This gradual warming of the earth is in occurrence at an extremely slow rate but it is happening. Many scientists believe that as human’s work and release greenhouse gases into the earth’s atmosphere, it can become dangerous for the long lasting life of humans and our environment. “Unless we take immediate action, the impacts of global warming will continue to intensify, grow ever more costly and damaging, and increasingly affect the entire planet - including you, your community, and your family” (“Global Warming Impacts”).
