Global warming is the rise of temperature of the Earth. The main cause of global warming is the greenhouse effect. The way humans behave is the reason that greenhouse gas trap more heat. Automobiles are the main cause of the greenhouse gases to to trap the heat. Global warming doesn’t completely mean a constant rise in temperature, it is mainly a change in temperature.in patterns.
The two major greenhouse gases include methane and carbon dioxide. Carbon dioxide and methane normally come from Earth’s atmosphere. The greenhouse gases are enhanced because of our human activity. The greenhouse gases are known as synthetic chemicals.
Our Earth has had at least five ice ages. The very first ice age we have had occurred nearly 2 billion years ago. Also, our most recent ice age started happening close to 3 million years ago. The most recent ice age is still happening today so technically we live in an ice age. An ice age is a long period of time when the planet is semi-cold and the earth is covered in giant sheets of ice in some areas. During an ice age we experience short flashes of very warm weather. Sometimes during the heat flashes the glaciers can melt.
The medieval warming period happened from about 950 through 1250. The medieval warming period was a time when the temperatures were risen in the North Atlantic region. The medieval warming period took place in the European middle ages. Recently after the medieval warming period there was a cooler time called the little ice age.
The little ice age lasted from 1250 to the end of the nineteenth century. It has been found that neither the little ice age or the medieval warming period were global, the two only took place in the North Atlantic region.

...gases to go into a strong effect. The greenhouse gases trap all of the heat in our atmosphere and make it hotter. Humans have let ultraviolet rays into the ozone layer. Destroying the ozone will make the Earth much hotter.
The temperature is rising at very fast speeds. In the last hundred years our Earth’s temperature has risen a full degree. The temperature is rising because of what us humans are doing to the environment.
Besides the greenhouse effect, one of the most harmful thing to global warming is the ultraviolet radiation. I agree that global warming is a moral issue because it is our fault. We have to work together to prevent global warming. We need to find a better way of transportation and better ways of not enhancing the greenhouse effect.

One of the main causes of the increase in Earth’s temperature is greenhouse gases. Greenhouse gases are gases that are trapped in the atmosphere. The gases consist of carbon dioxide, nitrous oxide, and methane. They trapped heat from the sun from returning back into the atmosphere. Over the last 100 hundred years we have increased the earth’s average temperature by 1.4 degree fahrenheit (Carey). This is mainly due to the fact we are producing ten times more greenhouse gas than before. It is exp...
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.
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
This process is called the greenhouse effect. The main gases are mostly carbon dioxide, water vapor, and methane. The problem now is that we are adding too much greenhouse gas to the atmosphere, especially carbon dioxide. These additions of carbon dioxide are known as carbon emissions. As the amount of carbon dioxide and other greenhouse gases in the atmosphere increases more and more heat ...
Greenhouse gas is a type of gas in atmosphere which absorb and emit radiation.Certain gases will block by atmosphere when escaping from the Earth and keeping the Earth warm.Therefore,this process is called Greenhouse Effect .The primary gases in the Earth are water vapour , carbon dioxide , methane , nitrous oxide and chlorofluorocarbons etc.However,human activities are changing the natural greenhouse.According to the IPCC Fourth Assessment Report issued on 2 February 2007 , it can be observed that there was a significant increase in globally averaged temperatures since the mid-20th century .One of the reason is the industrial revolution ,the develop...
The Little Ice Age is the name for the period of cooling spanning from 1400 to 1900 c.e. that took place after the Medieval Warm Period. Scientists believe that solar minimums and reversals in the Northern Atlantic Oscillation, a large atmospheric-circulation system that affects weather in the North Atlantic area including Europe, drove these changes (Encyclopedia Britannica, 2014). It is often assumed that the Little Ice Age had a global impact. However, in 2001, the Intergovernmental Panel on Climate Change put forth in a climate assessment report that though there were glacial increases in other parts of the world, they were not synchronous with the glacia...
What is Global Warming? Why is it important, or not important? Well, global warming is the gradual increase in the temperature of the earth’s atmosphere generally attributed by the increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants. Global Warming is real and is a current problem that we live with every day. Part of the cause of global warming is Study shows that the Earth’s temperature around the world has increased by more than 1 degree Fahrenheit since the late 1800s. In the Arctic about twice of the temperature around the world has also risen. This issue affects our daily temperature. Global warming has become a subject of political controversy. This debate has been subject to whether humans are at fault or if it is just a course of nature. Although many debates go on, questions of how to respond or help slow down the process of global warming are much more important focus. The main cause of global warming is the human contribution of the “greenhouse effect”. The Greenhouse effect is a cycle in which the temperature on Earth raises, during this, certain gases in the atmosphere trap energy. Global warming is a serious subject, very real subject that is being addressed and can be slowed down.
Over the course of human history, temperatures have significantly increased. From the 1980s to the 2000s, the increase has been the most noticeable. The average global temperature has raised approximately .5 degrees Celsius.
Global warming is occurring at a much faster rate and that is due to climate change. Climate change was what caused one of our greatest mass extinction that occurred during the Pleistocene era. Nevertheless, along with that mass extinction new species replaced the old ones and humans who drastically affected the environment. Climate
It seems that most of the warming started from the mid-twenty century is owing to greenhouse gases (GHG) such a carbon dioxide as a result of activities. European Environment Agency (2016, February 24) informed that the global temperature has risen
Global warming and global climate change is the study of future increases of temperature across the globe. Studying climate change refers to how the over- all climate will change such as the dry places getting dryer and the wet places getting wetter. Global climate is dependent on “the greenhouse effect a natural process that helps regulate temperature” (Easterling and Karl). In the past few centuries humans have had a monumental effect on increasing of greenhouse gases in the atmosphere. Climate change is result of the increase amount of the greenhouse gasses in the atmosphere such as methane, carbon dioxide, water vapor, nitrous oxide, and ozone. “Global temperature has rose approximately 1.4 degrees Fahrenheit over
Although it may not feel like it, we are currently in an ice age today. An ice age is just a period of time when the Earth’s climate faces a radical decrease in temperature and remains constant. Periods of colder temperature during an ice age have been called "glaciations" because they result in something being covered by glaciers or ice sheets. Intervals of warmer, irregular temperatures have been called "interglacials", which is what we are currently living in today (Eldridge and Biek). However, some scientists believe that the climate may dramatically decrease in the near future, and we could see glaciers return again like we did in the last glacial period. This last glacial period is referred to as “The Ice Age.” It was the most recent glacial period within our
It is known that in the last 650,000 years there have been seven cycles of glacial advance and retreat with the last one 7,000 years ago. This was when the modern climate era started which lead to the beginning of human civilization all
Global Warming is a condition caused by greenhouse gases and human activities. The increased concentration of greenhouse gases due to activities such as deforestation and fossil fuel burning is causing the Earth’s atmosphere and oceans to warm up. As a result of this, global warming has some serious effects in the shape of extreme weather, species extinctions, and rising sea levels. These effects can contribute to the changes that are taking place all over the world, most of which are dangerous enough to pose a threat to the survival of life on Earth in the future.
As Robert Frost once said, “ Some say the world will end in fire, some say in ice. From what I’ve tasted of desire I hold with those who favor fire.” This excerpt can relate to the idea of global warming. Global warming can be defined as an increase in the earth's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. During the past 10,000 years the earth has been in an ever-growing cycle that has significantly changed the climate. These changes are becoming more prevalent in our world today in the past 150 years. Scientists have been analyzing the causes and effects of the greenhouse effect and many other issues that global warming has presented. As John Houghton states in his book, Global Warming the Complete Briefing, on page 2 “ The 1980s and 1990s were unusually warm. Globally speaking, the decades have been the warmest since accurate records began somewhat over a hundred years ago and these unusually warm years are continuing into the twenty-first century.” There are countless records that show that our world as a whole is getting warmer, and the facts cannot be disputed. 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 be increased.
