the current rate of change due to human activity is unprecedented during at least the last 10‚000 years. The projected range of temperature rise is wide because it includes a variety of possible future conditions‚ such as whether or not we control greenhouse gas emissions and different ways the climate system might respond. Temperatures over the US are expected to rise more than over the globe as a whole because land areas closer to the poles are projected to warm faster than those nearer the equator

2013 Greenhouse Effect Today‚ the world is suffering because of the global warming‚ and this phenomenon has a relationship with Green House effect. First of all‚ the principle of green house effect is based on the wave length of radiation. Higher temperature objects emit radiation that has short wavelength. On the contrary to this‚ lower temperature objects emit radiation that has longer wavelength. Based on this fundamental‚ people can raise any crops in any seasons in greenhouse. The radiation

efficient solutions of this problem are a moratorium of deforestation‚ a universal carbon tax and international cooperation. Global warming is a tendency which there is an increase in earth’s surface temperature which is caused by excess greenhouse gas emissions. The phenomena of this problem are the change of global climate‚ the melting of ice cap and the increase in sea level. A research organization reported that “in the 20th century the average global surface temperature has increased

are still a major part of it. Greenhouse gases‚ such as carbon dioxide‚ absorb and emit heat in the atmosphere‚ keeping Earth warm enough to support life. However‚ human activities‚ such as burning fossil fuels‚ are adding large amounts of greenhouse gases to the atmosphere. Earth must get rid of energy at the same rate it receives energy. More greenhouse gases mean that more heat is being held in the atmosphere‚ which in turn makes temperatures higher. All the greenhouse gases people have added to

Consequences of greenhouse-effect temperature rises Predicting the consequences of global warming is one of the most difficult tasks for the world’s climate researchers. This is because the natural processes that cause rain‚ hail and snow storms‚ increases in sea level and other expected effects of global warming are dependent on many different factors. It is also difficult to predict the size of the emissions of greenhouse gases in the coming decades‚ as this is determined to a great extent by

into the atmosphere as warm‚ long-wave radiation. The atmosphere of earth is full of so-called greenhouse gases such as water vapor‚ carbon dioxide‚ ozone‚ methane‚ and nitrous oxide that act like a blanket‚ trapping some of the heat radiating from the land and oceans and preventing too much energy from escaping into space. The gas blanket works in much the same way as the glass panels of a greenhouse‚ serving to trap energy and keep temperatures at a steady level. The trapped heat keeps earth at

technologies. These are characterized by a lesser reliance on fossil fuels. (Sisco P.‚ 2006‚ p. 48) Greenhouse gases are emitted into the atmosphere as a result of the increased energy consumption. The energy was obtained by driving and using electricity and through other activities. These activities are used to support the quality of life including such aspects as growing food and raising livestock. Greenhouse gas emissions are the things that can be minimized through simple measures. These include the

They’ve looked at the natural cycles and events that are known to influence climate. But the amount and pattern of warming that’s been measured can’t be explained by these factors alone. The only way to explain the pattern is to include the effect of greenhouse gases (GHGs) emitted by humans. To bring all this information together‚ the United Nations formed a group of scientists called the Intergovernmental Panel on Climate Change‚ or IPCC. The IPCC meets every few years to review the latest scientific

form of infrared waves. Due to the presence of greenhouse gases such as water vapor‚ carbon dioxide‚ methane‚ and nitrous oxide‚ most of this radiation is trapped in the atmosphere. This is nature’s way of keeping the Earth at a comfortable temperature; without it‚ this planet would be too cold to even live in. You cannot exactly say they are harmful; it’s just that now we have greatly increased the amount of carbon dioxide (CO2) along with other greenhouse gases‚ thereby thickening the atmosphere trapping

4 EFFECTS 5 WHAT CAN I DO? 6 BIBLIOGRAPHY 7 The issue The worldwide community has reached an agreement about the global climate; the world is undoubtedly warming. This warming is the result of emissions of carbon dioxide and other greenhouse gases from human activities‚ such as industrial processes‚ changes in land use‚ and deforestation. If we continue‚ the temperature is expected to rise by 400% by 2100‚ and warming in the U.S. is expected to be even higher. This warming will have
