An inconvenient truth According to the movie I have watch in sm cinema last march 5‚2011. I have notice that Carbon dioxide and other gases warm the surface of the planet naturally by trapping solar heat in the atmosphere. This is a good thing because it keeps our planet habitable. However‚ by burning fossil fuels such as coal‚ gas and oil and clearing forests we have dramatically increased the amount of carbon dioxide in the Earth’s atmosphere and temperatures are rising. We’re already seeing

Water Management Describe Water Management and Use Ground water and surface water make up freshwater sources in the form of streams‚ rivers‚ and wells. Freshwater sources are becoming depleted. We are facing a growing global water shortage due to precipitation‚ runoff patterns‚ droughts‚ and ground water withdrawals. Water conservation is protecting the quantity and quality of the water resources‚ with expectations to reduce the total amount of water being used for various purposes. Water

Naturally occurring greenhouse gases include water vapor‚ carbon dioxide‚ methane‚ nitrous oxide‚ and ozone. Certain human activities‚ however‚ add to the levels of most of these naturally occurring gases: Carbon dioxide (CO2): released into the atmosphere when solid waste‚ fossil fuels (oil‚ natural gas‚ and coal)‚ and wood or wood products are burned. Methane (CH4): emitted during production and transport of fossil fuels (coal‚ natural gas‚ and oil‚) from the decomposition of organic wastes

because humans have been releasing more and more greenhouse gases into the atmosphere for a variety of reasons. We are doing this by burning fossil fuels. When fossil fuels are burned‚ they release harmful greenhouse gases into the atmosphere. These greenhouse gases then remain in the atmosphere‚ and trap most of the heat from the Sun‚ causing the global temperatures to increase. There are three main reasons for why humans are beginning to put more greenhouse gases into the atmosphere. The main thing

he contradicts that there was an extremely high level of carbon dioxide and that the greenhouse gases alone were not sufficient to compensate for the faint early sun. Instead Rosing turns to the idea that in Earth’s early history‚ the low albedo was what kept the planet warm along with little help of the greenhouse gases. The paper’s findings have given a proper explanation as to why the Earth was

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

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

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

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

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
