There are mainly two separate arguments for global warming and climate change. Some people believe that global warming and climate change do exist, and humans may have caused these problems. Others believe that global warming and climate change are simply natural cycles of the earth, or simply does not exist. Global warming and climate change are argued both as environmental issues caused by humans, and also largely exaggerated natural occurrences.
Most people don’t understand that there is, in fact, a difference between global warming and climate change. Global warming and climate change are used interchangeably by many people, including political leaders. “Global warming” refers to higher global temperature averages that rise over a long period of time. “Climate change” refers to the results of increasing temperatures (global warming), which are changes in climate such as heat waves.
The first major belief is simply that global warming and climate change do exist. The number of hurricanes, heat waves, and other extreme weather patterns are increasing, which is supposedly a cause of climate change. We’ve all heard about the recent Hurricane Katrina, Hurricane Sandy, extreme droughts, etc. These extreme changes in weather, or catastrophic events are said to be causing climate change. Like I explained before, global warming causes climate change, and experts like Al Gore say that extreme weather patterns are a result of global warming, which is causing climate change. Also, according to National Geographic, “Average temperatures have climbed 1.4 degrees Fahrenheit (0.8 degree Celsius) around the world since 1880, much of this in recent decades, according to NASA's Goddard Institute for Space Studies.” This is basically showing ho...

...ooling. Scientists also discovered that aerosols wouldn't cause global cooling, but instead they would cause global warming. Finally, shortly after J. Murray Mitchell's research was published, scientists discovered that his trends were not global. The global cooling idea was relevant in the Northern Hemisphere, but the Southern Hemisphere was proven to be warming, not cooling. The global cooling debate was proven unreal.
Unlike the 1970's global cooling debate, global warming and climate change are still being studied and argued. Some argue that global warming and climate change could be caused by humans. Others say that global warming and climate change are just naturally occurring cycles of the earth. I think we can all agree that the earth is warming, but the question is, did humans cause this issue? And also, how much warming is enough to actually affect Earth?
Climate change and Global Warming are out of control. This means that, no matter what policies, processes or actions are implemented, the Earth as we know it will never be the same again. There is significant evidence to support this hypothesis. The dilemma becomes whether we can limit the damage and adapt to a new status quo or not. Rising sea levels and the damage caused by this phenomenon has irreversible impacts on coastlines worldwide. Damage to sensitive reef systems cannot be fixed. This also has permanent impacts of the ecology not just of those immediate areas but also the ocean as a whole.
Global Warming, much of what does or does not happen forty years from now rests on our actions or inactions taken between now and then. The crucial question is whether we should pour all our resources into mitigation – reducing our carbon emissions. According to scientists who study the climate there are other environmental problems; “we now face a global crises in land use and agriculture that could undermine the health, security, and sustainability of our civilization”.
Climate change describes the changes that are happening to the planet in different countries or regions (NASA, n.d.). Climate change is caused by global warming,
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 warming is a scientific, political, and controversial topic. Some believe it is catastrophic, a slow moving killer hiding in the shadows. Others do not even think twice about it as they race by in a Hummer. Global warming is the gradual increase of temperature throughout different climates. It is caused by the greenhouse gas effect in which greenhouse gases, like methane and carbon dioxide, reflect sunlight back and forth. This reflected ultraviolet light bounces between the earth and the ozone layer and becomes trapped, resulting in a gradual rise of temperature. Over time, the slow rise of temperature causes new climates throughout the globe. The article “What Megablazes Tell Us About the Fiery Future of Climate Change” by Tim Dickinson
Scientist have been studying global warming since the early 1800s, and now sixteen years later think they may have found a missing puzzle piece to the mysterious “global-warming hiatus.” So, what is global warming? According to Merriam-Webster Dictionary global warming is “an increase in the earth 's atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting especially from pollution.” So, what is greenhouse effect? According to the Merriam-Webster Dictionary the greenhouse effect is “the warming of the Earth 's atmosphere that is caused by air pollution. The greenhouse effect occurs when warmth from the sun is trapped in
According to Erik Conway of NASA, “Global warming refers to surface temperature increases, while climate change includes global warming and everything else that increasing greenhouse gas amounts will affect” (Conway). Recently the United States has experienced a drop in temperature. This past weekend I was walking with a friend. With nothing to talk about, the awkward silence was finally filled with a comment on the weather. He said, “It’s so incredibly cold! So much for global warming!!” What my friend, nor I at the beginning of the semester, did not understand was that “temperature change itself isn’t the most severe effect of changing climate. Changes to precipitation patterns and sea level are likely to have much greater human impact than the higher temperatures alone” (Conway). Thankfully the national media has begun to increasingly reference the more scientifically significant term: climate change.
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?
Throughout history climates have drastically changed. There have been shifts from warm climates to the Ice Ages (Cunningham & Cunningham, 2009, p.204). Evidence suggests there have been at least a dozen abrupt climate changes throughout the history of the earth. There are a few suspected reasons for these past climate changes. One reason may be that asteroids hitting the earth and volcanic eruptions caused some of them. A further assumption is that 22-year solar magnetic cycles and 11-year sunspot cycles played a part in the changes. A further possibility is that a regular shifting in the angle of the moon orbiting earth causing changing tides and atmospheric circulation affects the global climate (Cunningham & Cunningham, 2009, p.205). Scientific studies suggest that all these played a role in past global warming and cooling periods. Today, however, there is a lot of conflict on whether humans are causing a global warming that could be disastrous to humans and all species of plants and animals on this earth. This paper will first explain the greenhouse effect, then take a look at both sides argument, and, finally, analyze the effect of global warming on world-wide sustainability
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 continue 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 ocean. The average temperature on the Earth was increased by 0.6C. There are various reasons of global warming, such as human activities, natural events, increasing of gases, such as carbon dioxide in atmosphere and solar activity (Global warming). Nearly 200 countries have signed Kyoto Protocol and they must reduce four greenhouse gases, in order to struggle with global warming. There are several perspectives about effects of global warming on environment. In this essay will be considered the impacts and consequences of global warming . In the process, it will be clarified that there are positive and negative impacts of global warming.
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
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.
Global warming and the greenhouse effect are issues discussed by scientists all the time. A natural process that keeps earths temperature at a livable rate is called the greenhouse effect. The energy from the sun warms up the earth when the rays from the sun are absorbed by greenhouse gasses. The gasses then become trapped in the atmosphere. Carbon dioxide, water vapor, methane and nitrous oxide are the most common greenhouse gasses. Greenhouse gases cause the radiant heat of the sun to be trapped in the Earths lower atmosphere which causes global warming. If there weren’t any greenhouse gasses, the earth would be really cold due to very little sun rays being absorbed on the earth. Global warming can and will lead to several problems that affect the environment in which we humans live in. These problems can lead to warmer temperatures all around the world, it can endanger animals and the wildlife, and it can lead to widespread flooding from the glaciers melting. Here are a few more future effects that I will discuss in more detail about. Damage to human health, Severe stress on forests, wetlands, and other natural habitats, how fish will be affected. Global warming is a serious problem that will affect our generation when we are older.
Climate change is one of the most discussed topics of the twenty-first century. Although this subject is very often on the daily basis of lots of people, most of them do not know much about it. So let us define climate change. People think that climate change is the same thing as global warming. However, global warming only represents one aspect of climate that is temperature. Climate change is any significant change in temperature, precipitation, or a wind pattern that occur over several decades or longer.
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 increase. A main cause in the recent studies of global warming is the use of aerosols. Aerosols are a substance enclosed under pressure and able to be released as a fine spray, typically by means of propellant gas. An aerosol can range from hairspray all the way to dust particles in the air.
