During this period, all over the world is facing with one of the biggest problem, the Global Warming. Global Warming makes average level of Earth’s temperature increasing this is causing by two main phenomena; increasing of greenhouse gases levels all over the world and ozone depletion in the atmosphere. Greenhouse effect made up by several groups of gases that we know as greenhouse gases. In general, the levels of these gases were controlled by nature, so the level of the greenhouse gas was constant and in the appropriate amount but because of human activities such as fossil fuel combustion, intensive agriculture and over global population take role and disturb the nature activity. They were increasing the level of greenhouse gases around the world. Ozone depletion is when the layer of ozone becoming thinner and thinner by some type of gases such as chlorofluorocarbon (CFCs). So that mean greenhouse effect and ozone depletion related to each other by be the main cause that make Global warming happen.
Greenhouse gases have both advantage and disadvantage. Greenhouse gases are the several group types of gases that can be absorbing solar radiation in the atmosphere such as carbon dioxide, methane, and water vapor. Approximately 75% of the radiations that come from the sun were absorbed by greenhouse gases in the atmosphere. Moreover, about 50% of radiation that was absorbed by greenhouse gas was radiated downward to Earth surface. So because of this phenomenon sustained the overall Earth’s temperature limited it into the proper amount that all of the living thing can be lived. However, greenhouse gases could be the big deal if there are becoming too much. Since the Industrial revolution happen the human activities, fossil fuel comb...

..., and industrial revolution have increased greenhouse gasses in the atmosphere. Greenhouse gases are beneficial for the environment, without them humans wouldn't be able to live on earth. The job of greenhouse gases is to allow sunlight to come into the atmosphere, and then absorb infrared radiation to warm up the earth. The four main greenhouse gases are carbon dioxide, methane, water vapor, ozone, and methane. Among all the greenhouse gasses CO2 plays the an important role because it accounts for 80% of total greenhouse gas emission ( Gore, 2006). In Dr. Cowley’s study he noticed that when past radiance of the sun and volcanic activities were put into a computer model to simulate the energy flow from earth and to earth. The computer produced temperature matching those of the climate from a 1000 years ago. But temperature changed completely in the 20th century.
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
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...
A greenhouse gas is any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere. By increasing the heat in the atmosphere, greenhouse gases are responsible for the greenhouse effect, which ultimately leads to global warming. (EPA Environmental Protection Agency, 2014)

Air pollution and greenhouse gases are the reason for the planet as it is today; the reason why we see campaigns flooding the media informing us to ‘switch off’, ‘save the planet’ and ‘turn down the heat’ and the reason why the government is trying to develop a successful scheme, such as the carbon tax scheme, to reduce air pollution caused by major industries. Air pollution and greenhouse gases are the two immediate causes of global warming and climate change. Air pollution occurs when chemicals or particulate matter enter the atmosphere. They can cause damage to living organisms on the planet, as well as destruction to the natural and synthetic environment (Energy Environment.net 2008). Greenhouse gases are gases in the atmosphere that absorb infrared radiation emitted from the earth. They trap infrared radiation in the form of heat, and hence contribute to global warming. Anthropogenic greenhouse gases are a direct result of air pollution. They are the physical gases emitted that cause air pollution. Naturally occurring greenhouse gases also have an influence on the earth’s atmosphere, though it is not as conspicuous as anthropogenic causes. Together, air pollution and greenhouse gases are intensifying climate change and global warming on a world-wide basis.
The commonly debated “greenhouse effect” refers to “the global average temperature increase that has been observed over the last one hundred years or more” (Spencer). President Barack Obama addressed the issue in an effort to highlight its severity, "We have to all shoulder the responsibility for keeping the planet habitable, or we’re going to suffer the consequences – together” (Leader). The earth’s increasing atmospheric and oceanic temperatures result in climate changes due to cumulative amounts of carbon dioxide (CO2) in the atmosphere. As an outcome, researchers around the globe have established that the by-product of burning fossil fuels is the main culprit of the increasing temperatures. Global carbon emissions from fossil fuels have significantly increased since 1900, as shown above from a study carried out by the Carbon Dioxide Information Analysis Center.

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.
The “greenhouse effect” is the most prominent cause for the rise of global temperatures. According to the book, “Earth’s Changing Environment” the warming of the earth’s climate is due to a collection of gases in the atmosphere. There are various gases in our planets atmosphere, including: water vapor, carbon dioxide, nitrous oxide and methane. These gases, called greenhouse gases, absorb a large portion of the radiation from the sun and send it back to the ear...
Global warming is the gradual rise in temperature and oceans due to recent human activity. This is created by the production of too much carbon dioxide that is released into the earth’s atmosphere. The carbon dioxide, also known as a greenhouse gas, remains in the air trapping heat and gradually warming the planet. Other greenhouse gases such as: methane, nitrous oxide, and water vapor also contribute to this slow warming. According to Live Science, The state of these gases being trapped is called the greenhouse effect, which is one of the leading causes of global warming (Lallanillia). All the gases are created differently and have different effects on the earth. As for some greenhouse gases can be in the atmosphere for a short amount of time, other gases can remain in the atmosphere for thousands of
Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. This results in an increased evacuation of greenhouse gases. “Short-wave solar radiation sinks into the Earth's atmosphere and warms its surface while long-wave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by trace gases.” (2)
