The Greenhouse Effect is the phenomenon by which heat from the earth’s atmosphere warms up the surface of a planet to an unusually high temperature. As we know, the planet is a relatively cool place, at least compared to its star system, and is in fact known as the “coolest” planet in our solar system. But its surface temperatures, which are often at least five times higher than those on our own world, may also be a factor in climate change.
Although the Green House Effect is generally thought of as the cause of climate change, other factors such as variations in the amount of sunlight reaching the earth, atmospheric humidity and wind speeds are also believed to play a role in our planet’s ability to retain heat. The phenomenon has been used in various forms of science fiction movies, and some scientists argue that it is actually the primary cause of how Earth’s climate changes.
One way to study the Green House Effect is by looking at temperature changes in different parts of the globe in relation to one another. Global warming theory says that global warming is caused by the increased emission of carbon dioxide in the atmosphere and this increase is primarily the result of burning fossil fuels. While there are many theories on how the Green House Effect works, the only way to know for sure is to go back to the basics: the earth’s temperature, and the amount of energy that getting into and out of it. The result is the greenhouse effect.
In simple terms, the greenhouse effect is created when a large amount of energy (or carbon dioxide) is emitted from a source, but is also being lost by the receiver. The result is a rise in temperature because the absorbed energy cannot be properly utilized. A decrease in pressure on the opposite sides of the absorption curve means that the greenhouse gas stays put while the temperature rises.
This is what makes greenhouse gases “green.” When they are allowed to stay in the environment, these gases act as a natural filter, absorbing most of the sunlight that comes into the earth and releasing it as heat. However, it is important to note that because greenhouses are kept open, the carbon dioxide from the air is not completely absorbed by the earth, but instead moves to other parts of the planet where it is more easily accessed and converted into carbon dioxide.
There are many types of greenhouse gases that can be released into the atmosphere. Greenhouse gases that are released into the atmosphere can be made by activities such as deforestation, agricultural practices, construction, landfills, and burning of fossil fuels. or even the exhaust of vehicles. These types of greenhouse gases are known as carbon dioxide emitters.
Other greenhouse gases are not produced by human activities and are expelled from the earth as snow, fog and rain. As the water content on earth increases, it takes up more carbon dioxide and thus makes it harder for the earth to absorb. There is also carbon dioxide in the atmosphere that is released by plants, as the plants and soil absorb carbon dioxide from the air as they grow.
Since it is difficult to measure the greenhouse gas levels in the earth’s atmosphere, scientists rely on the Greenhouse Effect to determine what their current state is. As a result, a constant measurement is required to determine the effect of human activity on the earth’s climate and, if necessary, to take action to prevent further deterioration.
There are a number of methods used to track the greenhouse gases being released into the environment. However, it is important to note that the global warming that is currently being experienced by many parts of the world is caused primarily by human activities, not by greenhouse gases. Scientists have yet to find a method of tracking greenhouse gases that is able to show the effect of human activity on the earth’s environment at the same time that greenhouse gases are being emitted from manmade sources.
Scientists are using a variety of techniques to determine greenhouse gases and the greenhouse effect. These include: infrared thermography; satellite imaging; infrared thermography using a laser beam; infrared thermography using a heat-absorbing material; and high-precision measurements through radio waves.
Greenhouse gases have been called one of the biggest threats to the earth’s environment today, and are the number one reason why the global warming debate has heated up. Because of the potential threat that the greenhouse gases pose to the environment, it is important that we protect our planet by decreasing the greenhouse gas levels in the air and reducing the number of greenhouse gases entering the atmosphere.
