Threat of Global Warming
There are two burning questions that I feel need to be answered before exploring the aspects of global warming. They are what is the greenhouse effect and how does the green house effect contribute to global warming? Gases in the atmosphere are transparent to visible light but absorb infrared (heat) waves that are reradiated from the earth’s surface (Cunningham, Cunningham, Saigo 05). However, some greenhouse gases occur naturally in the atmosphere, while others result from human activities. Naturally occurring greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Carbon dioxide is released to the atmosphere when solid waste, fossil fuels (oil, natural gas, and coal), wood and wood products are burned. Methane is emitted during the production and transport of coal, natural gas, and oil and the raising of livestock.
The atmosphere, when loosely compared to the glass of a greenhouse, transmits sunlight while trapping heat inside is called the green house effect. The greenhouse effect is a natural atmospheric process that is necessary for life, as we know it. Too strong of a greenhouse effect that is caused by the burning of fossil fuels and deforestation, may cause harmful environmental change. The greenhouse effect is only troublesome when it gets too strong and warms things too much. And that’s just what scientists say has happened over the last 150 years or so as the people of industrialized nations have extracted Earth’s vast buried stores of fossil fuels and burned them.
Each greenhouse gas differs in its ability to absorb heat in the atmosphere. Methane traps over 21 times more heat per molecule than carbon dioxide, and nitrous oxide absorbs 27...

...appen if deforestation stopped entirely? Would the greenhouse effect stop immediately or would it take many, many years? We as humans are smart enough to stop doing things that will ultimately destroy human kind. Aren’t we? More studies must be done to find a definitive answer in order to save mankind. Or is this the way that history dictates that in this one million years global warming is inevitable?

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...
In order to talk about global warming, we must first learn what causes the greenhouse effect. The three most common greenhouse gases are water vapor, carbon dioxide, and methane. Many of the sun’s rays are absorbed by water vapor. Water vapor is a natural atmospheric gas and it accounts for “80 percent of natural greenhouse warming; the remaining 20 percent is due to other gasses that are present in very small amounts” (Murck, Skinner, and Porter 488).
Greenhouse gases are a number of gases contributing to global warming, which heats up the earth. The greenhouse gases that are emitted are carbon dioxide, methane, nitrous oxide and more. The greenhouse gases absorb infrared rays (heat) emitted from the Sun, which will be kept in the earth’s atmosphere rather than being reflected away into space, which helps the earth’s temperature to remain constant. The industrial world on earth contributes carbon dioxide by burning fossil fuels in factories. Fossil fuels give out carbon dioxide when burned and trees are cut down which also gives out carbon dioxide as plants absorb carbon dioxide.
Many factors have contributed to climate change, some natural such as vibrations in the orbit. However, scientific facts might lead us to believe that the vast majority is thanks to mankind. The greenhouse effect being one of them, such effect is defined as the trapping of the sun’s warmth in a planet’s lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet’s surface. For hundreds of years we have been aware that greenhouse gases such as CO2 trap heat but be

Global warming has a big impact on climate change. It happens when green house gases like carbon dioxide, water vapor, nitrous oxide and methane trap the heat and light from the sun in the earth surface (Global warming and its effects). This is how the temperature is increased. The green house effect is when the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere (Green house effect). This is like when heat is trapped in a car, o...
The most common type is air pollution , and it is the most dangerous one . For the people who live in big cities they are very familiar with air pollution . but there are different kind of air pollution ,some visible , some not which leads to global warming. Generally any substance that interrupts with the atmosphere and has a damaging effects on the atmosphere is considered air pollution. There is a lot of kinds of greenhouse gases .The most common or popular type is carbon dioxide. Carbon dioxide is the main pollutant that is warming earth . carbon dioxides is widespread , and it is associated with cars , planes , factories , and other human activities that involves fossil fuel and burning gasoline , such activities caused the level or ratio of carbon dioxides to raise in the atmosphere .So most of the living creature and species breathe carbon dioxide while it is in the air .Finally , CFCs which is used in radiators and cooling systems , and aerosol propellants. But now they are banned after the noticed affect they do on ozone layer . CFCs interacts with ozone and removes it then replaces it with other gases that is not needed in the atmosphere , or in another language it creates new gases that is harmful .

Climate change and Global warming is a big issue in the world today. One big thing is the Greenhouse Effect. The Greenhouse Effect is the capturing of the sun's warmth in the planet's lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation given off from the planet's surface. Greenhouse gases affect the temperature here on Earth by sunlight hitting the Earth. Then, carbon dioxide reflects the heat from the sun and traps the heat, keeping it on the Earth causing a rise in temperature.
Which is creating greenhouse gases, I will focus on the activities humans do that create green house gases and overall affect climate change. There are three main ways how humans create gases, they are, the burning and use of fossil fuels, agriculture some gasses animals exhale and the last main way is the improper disposal of garbage and the excess of garbage being created. The first of those three issues i’m going to cover is the burning of fossil fuels or the use of fossil fuels. Fossil fuels are formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years. Then people extract these fossil fuels from the ground and use and sell them as energy source for us to use.
A greenhouse gas is “a gas such as carbon dioxide, ozone, or water vapor that contributes to the warming of the Earth’s atmosphere by reflecting radiation from the Earth’s surface” . “The naturally occurring greenhouse effect is necessary to provide a warm atmosphere conducive to life on Earth“, but because human activities increase the greenhouse gases the green house effect is badly increasing causing the temperatures to rise . Greenhouse effect is the “warming of the Earth’s surface as a result of atmospheric pollution by gases” . Because global warming today is not only caused by coal, but by oil , methane , and other greenhouse gases, consumers today should decrease the use of greenhouse emitting things and look for more efficient options in order to prevent and possibly reverse global warming. Global warming affects everything from the ocean, plants, and animals because of the increase in temperature.
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...

The earth's atmosphere is made up of five layers of gases that act as a blanket covering the earth. This blanket keeps in some of these gases to keep the planet warm. It is called the greenhouse effect. This is because it acts like greenhouse windows by letting in sunlight to warm the surface and air, and hold in most of the solar generated heat.
However, one of the reasons that humans still carry out certain activities that continue to pose a threat to the environment such as deforestation is mainly for agricultural purpose, which is responsible for feeding the world’s 7.2 billion population. In that case, global warming will still remain as a growing t...
