Richard Kaloust Greenhouse Effect on Earth

The Effect of Green House Gases

Richard Kaloust Effect Of Green House Gases By Eleanor B. Jhonsons.

Earth, the only planet in our solar system or as far as evidence indicates the only planet in the whole Universe that supports life, was not like as we see it now since its beginning. Earth has been able to give a safe home to life because of its unique place in the solar system; it’s neither too close to the Sun nor too far away. As Earth is situated away from the Sun preventing it from being a hell of a warm place, there was the possibility that it may have been freezing cold for life to form and flourish here. But thanks to the greenhouse gases present in Earth’s atmosphere that play their role in keeping it warm enough.

Greenhouse gases are those gases residing in Earth’s atmosphere that absorb and emit radiation and thus, keep Earth warmer. The ‘Greenhouse Effect’ is the natural process through which these atmospheric constituents absorb sunlight. Sun, the only star in our Solar System, emits light that reaches Earth’s atmosphere. The greenhouse gases in the atmosphere absorb the long wave radiation emitted by Sun which warms the atmosphere and these long wave radiations are emitted both upward and downward; the downward emission of radiation by atmosphere is called the ‘Greenhouse Effect’.

The greenhouse gases present in Earth’s atmosphere are water vapor, carbon dioxide, methane and ozone. Water vapor is the most abundant gas and plays the lead role in warming earth causing 36-70% of ‘greenhouse effect’. Carbon dioxide contributes 9-26%, methane 4-9% while ozone’s share is about 3-7%. Some of the other greenhouse gases present in much smaller quantities are sulfur hexafluoride, hydro fluorocarbons, chlorofluorocarbons, per fluorocarbons and nitrous oxide. Two of the major components of Earth’s atmosphere, oxygen and nitrogen are thankfully not greenhouse gases otherwise earth’s atmosphere would have been far warmer than it is now.

Although, these greenhouse gases have been playing a major role in providing life on Earth the perfect temperature to survive, since the Industrial Revolution human activities have caused increase in quantity of green house gases in the atmosphere. More greenhouse gases will trap more and more heat from Sun giving rise to the Global Warming phenomenon. Rising temperatures can be potentially hazardous to all kinds of life forms on Earth and a major cause for rapid melting of glaciers which in turn will cause sea level to rise submerging many coastlines worldwide. Although, environmentalists are forcing the issue and many Governments are taking steps in the right direction, it is not the greenhouse gases but human intervention in nature that is to be blamed.

Climate Change – The Coming Crisis

Richard Kaloust Coming Crisis of Climate Change by Jonathon Hardcastle.

While many contend that there are different reasons behind the changing of our climate, few can deny that our planet is going through a period of immense changes. While some may discredit the science, global warming is one of the main hypothesis for why our planet is heating up. In this article, we’ll try to explain some of the science behind global warming so that you can understand the problem more clearly.

According to numerous scientific studies, our planet’s surface temperature has increased by about 1 degree Fahrenheit within the last century. Most of this change has occurred in the past two decades, prompting the question: are our lifestyles accelerating this global change? The evidence definitely seems to point in that direction.

Many scientists point to the emission of greenhouse gases as one of the leading reasons that we are undergoing this global change. Carbon dioxide, methane, and nitrous oxide are some of the main compounds that we are releasing more and more, causing something known as the ‘Greenhouse Effect’. This occurs due to the fact that these gases tend to trap heat, and when they are released into our upper atmosphere, they trap some of the heat energy that would normally be reflected by our earth’s natural processes.

It’s an undisputed fact that there is more greenhouse gas in our atmosphere due to humanity. Since the beginning of the industrial revolution, it is estimated that the amount of carbon dioxide in the atmosphere has increased by as much as thirty percent. While a little greenhouse gas helps to keep our planet warm, the more and more that we release, the hotter the planet is going to get. That is an important fact to consider, being that our biosphere is finely tuned to live at the temperatures at which our planet currently operates. Many forms of both plant and animal life run the risk of extinction should the temperature change be accelerated. Fossil fuels are primarily responsible for the amount of greenhouse gases that we are releasing, and to help fix the problem, we are going to need to find an alternate source of energy, and quick. Research into alternative fuels has yielded several possible options, including the use of corn in the production of ethanol, which has already had proven usage in places such as Venezuela. The most accelerated period of temperature change has occurred in the past twenty years, and it’s clearly evident that we need to address this problem while we still can.

Global Warming Caused By the Green-House Effect

Richard Kaloust Global Warming Causes By George Christodoulou.

The green-house effect is the most important cause behind global warming. In fact global warming is known as the greenhouse effect. This phenomenon leads to an increase in the Earth temperature due to certain gases like CO2, nitrous oxide, and methane. These gases trap the energy from the sun and without them the heat would go back into space and Earth would be one massive iceberg. Since these gases warm the Earth, they are known as greenhouse gases.

In the last couple of decades, people have started using glass houses to grow plants in winter and these are called greenhouses. Typically, these houses will trap the heat from the sun. The glasses in the greenhouse let the light through and at the same time prevent the heat from escaping.

As a result, the greenhouse heats up to keep the plants alive in the winter. Similarly, the greenhouse gases in the Earths atmosphere work like the glass and prevent the heat from escaping. The sunlight enters piercing through the cloud of greenhouse gases and when it reaches the Earths surface, it is absorbed by land, water, and air.

After absorption the same energy is sent back into the atmosphere. Some of it remains trapped in the atmosphere due to the greenhouse gases and this energy makes the Earth warmer. Since there has been an increase in CO2 emissions in the last couple of decades, more and more heat is being absorbed in the atmosphere. This is increasing the temperature of the Earth gradually and causing global warming.
