...Greenhouse Effect The Greenhouse Effect is a natural process through which various gasses and water vapour in the atmosphere affects the earth’s climate. It is so named because it acts like a glass greenhouse for plants by preventing the incoming heat from the sun from leaving causing warming of the earth just as the inside of a greenhouse warms. The Greenhouse Effect can also be likened to being under a blanket in the sunshine; the body under the blanket will heat up and the blanket will keep the heat from escaping causing warming. The earth’s climate is driven by this continuous flow of energy from the sun, mainly in the form of visible light. About 30% is immediately scattered back into space, but most of the remaining 70% passes down through the atmosphere to warm the earth’s surface. Being much cooler than the sun, the earth does not give out energy as visible light. Instead, it emits heat in the form of infrared or thermal radiation. Greenhouse gases in the atmosphere block this infrared radiation from escaping directly from the surface to space. By absorbing infrared or ‘Heat’ radiation from the earth’s surface, “greenhouse gases” present in the atmosphere, such as water vapour and carbon dioxide, act as blankets over the earth’s surface, keeping it warmer than it would otherwise be. The existence of this natural “greenhouse effect” has been known for nearly two hundred years; it is essential to the provision of our current climate to which ecosystems and we humans...

...Greenhouse Gases – Laboratory Assignment Prepared by XX 9/29/12 PART ONE Test 1 1750, Average temperature coming in at 57 degrees. Nearly an one to one ratio as equal amounts of both carbon dioxide CO2 and Methane CH4. Nitrous Oxide N2O was virtually invisible. It was a clean environment and It would be interesting to see just how fresh the air would have been to breath back in that time frame. There we're only a small rural farms, no automobile fossil fuels being burned. Test 2 Current: Average temperature coming in at 59 degrees. Carbon Dioxide CO2 is still being developed at a much greater rate with every increasing levels. Methane CH4 is having a harder time escaping, as the lever of build up has thickened. Nitrous Oxide N2O under microscopic review testing is appears to block red photons from being released back int the atmosphere. While some escape, most are being trapped. (Currently the USGCRP data showed since the pre industrial age, CO2 increased by 40%, CH4 by 148% and N2O by 18%) The test model animation could be flawed in how it is depicting the information based on these numbers. Test 3 2050 is not shaping up to be a comfortable place with an average temperature at 63 degrees. N20 Nitrous Oxide, is not escaping, and yellow photons are remaining trapped as well. Carbon Dioxide is escaping at a moderate level, with approximately, 1 out of six molecules bouncing back to earth. It is an exponential build-up with increased pollutions from an expanded...

...Vanessa Montes February 1st 2016 Sci/256 Professor John Jacobs Approximately 4.5 billion years before the Earth has been formed. It is very difficult to describe or flashback the millions years before what was the climate in the Earth in a particular place on particular day. However, unfortunately based on the some clues still remain in the rock, ice, trees, corals, and definitely on the fossils. Based on these clues it is clearly indicated that the Earth climate has changed many time before. There was a time period when the whole planet was covered with ice. Now the scenario has been totally changed. If we flashback just last 650,000 years back, there was an increased level of environmental carbon-di-oxide (CO2) and temperature and simultaneously decreased the cyclical pattern. Scientists have been studies and analyze enormous experimental trials to find out the better way and to understand the climate change in this planet. Some of the selective ways are following various weather forecast departments’ for the purpose of receiving the weather information send back to the earth viz. weather stations (for the measurement of temperature, rainfall, wind speed, and humidity; weather balloons (just float in a very high altitude in the atmosphere with a transmitter); weather satellites (sent a satellite to the space for getting the information regarding rainfall, temperature, cloud cover, etc.; ice cores (if...

...The Greenhouse Effect Introduction Greenhouse effect refers to an atmospheric process by which short wavelenghts of the visible light from the sun pass through the atmosphere where they are absorbed or trapped. However, part of light emitted from the sun in form of long wave is re-radiated from heated objects on the earth’s surface in to the atmosphere. Presence of greenhouse gases in the atmosphere does not allow the radiations to pass through. The greenhouse gas molecules are more complex than any air molecule and their structure has high heat absorption capacity. The heat radiated back to the earth’s surface to modulate its temperature. According to Parsons, this process is essential in order to support life. if this does not occur, the temperatures on the earth surface would be below freezing point and plant or animal life would be supported. However, human activities in the past centuries have increased the concentration of greenhouse gases in the atmosphere which in turn have increased the average temperature on the earth’s surface. Greenhouse gases include water vapor, carbon dioxide, nitrous oxide and methane. According to a report released by IPCC in 2007, there was a significant increase in production of greenhouse gases between the 19th and 20th century. However, in the context of this paper greenhouse effect will be deciphered via different notions. Discussion Increase in Effect Increase in population has led to increased transportation and manufacturing. This...

...Greenhouse Effect Greenhouse effect? What does greenhouse effect really means? According to Turnbull (2006), greenhouse effect is “the warming of earth’s atmosphere as a result of harmful gases in the air” (p. 325). It could be devastating if we let it to continue developing in our earth. We can reduce its existence even at our very own home. The 3R’s of environment, save electricity and also reducing the emission of harmful gases can reduce the level of greenhouse effect from our own home. Firstly, saving electricity at home is one of the ways to decline the level of greenhouse effect. According to Chong (2007), approximately 72% of electricity contributes to greenhouse gases. Just by turning off lights or fan when they are not in use by any people can reduce the temperature hence, reducing the level of greenhouse effect. Plus, installing solar panels on the rooftop of our houses to heat up our home and water can be a very effective way to save the use of electricity. Generally, use less electricity at home will bring down the percentage of this effect to happen. Secondly, reduce the emission of harmful gases can help shrink greenhouse effect. To illustrate, households should exclude the option of disposing their rubbish through opening burning in the lawn because burning of rubbish will emit harmful gases such as carbon monoxide and nitrous oxide. In addition, refrigerants in air-conditioners and refrigerator also help the growth of greenhouse effect as it releases...

...Think about a time when your car was parked in the middle of a parking lot, in the middle of the day. The minute you opened the car door, you must have felt currents of hot air blowing past you. The moment you sat down, you might have felt as if your car was burning the heat! This is a small, yet effective example of a process called the GREENHOUSE EFFECT. This effect involves a certain body of matter, be it a car, or a green house in which plants are grown, or the earth itself GRIPPING heat or radiation from another body, in our case – the sun. In case of the car, the glass enables the assimilation of the heat, and traps the heat inside, and does not let it out. Similarly, the earth's atmosphere contains certain gases called GREENHOUSE GASES such as Carbon Dioxide or water vapor or Ozone or Methane, which absorb the radiations we receive from the sun, and trap the heat from it inside. In other words, our atmosphere, which contains the green house gases acts like a blanket; it absorbs heat from the sun, and prevents the heat inside from going away from the earth's surface. The more greenhouse gases in the atmosphere, the more the heat gets trapped, the more the temperature rises. This phenomenon of increase in the average temperature of the Earth's near-surface air and oceans is called GLOBAL WARMING. So, what if the temperature rises? Due to global warming, there are serious, profound consequences that occur. These include: 1. Increased evaporation of water, which...

...Greenhouse effect From Wikipedia, the free encyclopedia Jump to: navigation, search A representation of the exchanges of energy between the source (the Sun), the Earth's surface, the Earth's atmosphere, and the ultimate sink outer space. The ability of the atmosphere to capture and recycle energy emitted by the Earth surface is the defining characteristic of the greenhouse effect. Another diagram of the greenhouse effect The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions. Since part of this re-radiation is back towards the surface and the lower atmosphere, it results in an elevation of the average surface temperature above what it would be in the absence of the gases.[1][2] Solar radiation at the frequencies of visible light largely passes through the atmosphere to warm the planetary surface, which then emits this energy at the lower frequencies of infrared thermal radiation. Infrared radiation is absorbed by greenhouse gases, which in turn re-radiate much of the energy to the surface and lower atmosphere. The mechanism is named after the effect of solar radiation passing through glass and warming a greenhouse, but the way it retains heat is fundamentally different as a greenhouse works by reducing airflow, isolating the warm air inside the structure so that heat is not lost by convection.[2][3][4] If an ideal thermally conductive blackbody was the...

...Argumentative Essay Is global climate change man made? Some would argue that climate changes are just stages of the Earth or doesn’t exist at all. Most would say that with all the people in the world and all the things that they do to Mother Nature that climate change is a man-made problem. In this essay, I’m going to explain both sides of the argument and give some facts about why they think that. First off, I think that climate change is man-made and it is from careless people on the earth that don’t think about the effects of things they do in the long run. We all leave some sort of carbon footprint. With population growing and getting out of control most people don’t realize a lot of the things they do are harmful to the planet. With more people, there is a need for more places to stay. People need homes and land so one of the major factors in climate change is deforestation. Another factor is the burning of fossil fuels like oil, natural gas, and coal. These energy resources are burned for electricity or refined to be used as heating or transportation usages. “Over the past 20 years, nearly three-fourths of human-caused emissions came from the burning of fossil fuels.” These things all have to do with letting too much carbon dioxide into the atmosphere. This is one of the major reasons of temperatures getting warmer. “Humans have increased atmospheric CO2 concentration by a third since the Industrial Revolution began.” Another factor in climate change is the release...

...production, deforestation, land use and etc., are playing a significant role that produce a lot of greenhouse gases and intensify climate change as living in modern society. Oil, gas and coal are the main fossil fuels and energy sources in our daily life. It produces a large amount of greenhouse gases. The greenhouses gases could increase the surface temperatures and delay cooling in the atmosphere (Giddens, 2009). Hence, this phenomenon is called as greenhouse effect and which causes the climate change and global warming. Climate change is an issue which cannot be abandoned to the next generation (Francis, 2015). Therefore,...

...Introduction Global warming is a phenomenon that occurs when the earth’s atmosphere traps heat radiating from Earth toward space. Initially the sunlight transmitted was meant to pass through the atmosphere, warm the Earth’s surface, and otherwise pass freely into space. But most of the outgoing heat, however, is absorbed by the accumulated greenhouse molecules in the atmosphere and is re-emitted in all directions, ultimately leading to the warming of the planet. Over the past 50 years, the average global temperature has increased at an unsettling speed. Some human activities like mining and the burning of fossil fuels, emit CO2 and other greenhouse gases into the air. As we burn and mine more fossil fuels, greenhouse gases build up in the atmosphere...

...The Greenhouse Effect and Global Warming: Definition, Causes, and potential effects to humans, Plants, animal communities and natural resources. Discuss with illustrations. INTRODUCTION There's a delicate balancing act occurring every day all across the Earth, involving radiation the planet receives from space and the radiation that's reflected back out to space. Enormous amounts of radiation, primarily from the sun strikes the Earth's atmosphere in the form of visible light, ultraviolet, infrared and other types of radiation that are invisible to the human eye. About 30 percent of the radiation striking Earth's atmosphere is immediately reflected back out to space by clouds, ice, snow, sand and other reflective surfaces, according to NASA (National Aeronautics and Space Administration). The remaining 70 percent of incoming solar radiation is absorbed by the oceans, the land and the atmosphere. As they heat up, the oceans, land and atmosphere release heat in the form of infrared thermal radiation, which passes out of the atmosphere and into space. It is this equilibrium of incoming and outgoing radiation that makes the Earth habitable. Without this balance, the greenhouse effect sets in. Definition Greenhouse Effect: The warming of the atmosphere due to the increased amounts of greenhouse gases such as carbon dioxide, nitrous oxides and methane. These gases form a blanket over the Earth, trapping the energy or heat from the sun and preventing it from leaving the atmosphere...

...Greenhouse gases are a significant factor in global warming, a topic of great debate in America. A greenhouse gas, or GHG such as carbon dioxide, is a gas that is trapped in the atmosphere. They are key factors in the Greenhouse Effect, a warming process. Automobiles and transportation are one of the leading sources of GHG emissions following industrial production, both of which rely on the combustion of fossil fuels for power. Carbon dioxide is the main gas that is released from burning fossil fuels such as petroleum. The problem with gas emissions released by industrial production is hard to cap, however, the problem involving the amount of carbon emissions released can be significantly reduced by cutting back on the amount of individual driving. This is important because transportation is one factor in the warming process that we can control. Many assume that buying a hybrid is a solution to the warming problem. While this is helpful it is not a large enough solution to make a major impact. One way to help cut-backs significantly is to increase and expand on public transportation while making it more efficient and safer for the environment. This would result in fewer combustion vehicles on the road, and an overall reduction in GHG emission. There are a few different types of GHGs that are harmful to the atmosphere. The main greenhouse gases are carbon dioxide, methane, and nitrous oxide. The GHGs methane and nitrous oxide are not very relevant in the combustion...

...and consequences of the enhanced greenhouse effect and global climate change Figure [ 1 ] - The greenhouse effect diagram, http://www.ozcoasts.gov.au/indicators/images/oze_fs_009_02.jpg Figure [ 1 ] - The greenhouse effect diagram, http://www.ozcoasts.gov.au/indicators/images/oze_fs_009_02.jpg “The unprecedented increases in greenhouse gas concentrations, together with other human influences on climate over the past century and those anticipated for the future, constitute a real basis for concern” (American Geophysical Union, 2014). The Earth's surface temperature has to be just right for humans, not too cold and not too hot. Thanks to the natural greenhouse effect, which has kept the Earth warm. It’s a phenomenon where the earth's atmosphere traps solar radiation, caused by the presence in the atmosphere of gases such as carbon dioxide, water vapor, and methane that allow incoming sunlight to pass through but absorb heat radiated back from the earth's surface. As there are naturally occurring greenhouse gases in the atmosphere that help keep the Earth warm, added amounts of these gases leads to extra heat being trapped in the Earth’s atmosphere. These gases (carbon dioxide, methane etc.) are being added by human activities and are enhancing the greenhouse effect as shown in figure 1. The global climate change is causing many environmental consequences and will cause more. There are five gases that contribute to the enhanced greenhouse effect. These five gases are water...
