The Greenhouse Effect ... Reducing greenhouse gas emissions is vitally important. The same is happening with livestock: climatic changes are directly affecting important species in multiple ways: reproduction, metabolism, diseases, etc. Concentrations are increasing at a rate of about 2–3 ppm/year. Over the past several millennia the average Earth temperature has been about 15 °C (59 °F). Greenhouse gases include water vapour, carbon dioxide, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons (CFCs). I don't think anyone has ever said it can't. This is the enhanced greenhouse effect, which is contributing to warming of the Earth. Invariably, there are both negative and positive effects of greenhouse effect. As we will see in section 7.3, simple theory shows that a rise in greenhouse gases should result in surface warming; the uncertainty lies in the magnitude of the response.It is well established that the global mean surface temperature of the Earth has increased over the past century by about 0.6 K. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.The absorbed energy warms the atmosphere and the surface of the Earth. As the average temperature of the earth is steadily increasing, the polar ice caps are rapidly undergoing a melt down. In the absence of this gas, plants will be unable to produce food. In fact, it is the human interference that has ruined the balance between the incoming and outgoing radiation, due to increased CO2 which is problematic.It is no surprise that human existence and life is only possible at a certain temperature. The greenhouse effect is defined by absorbing and reradiating infrared. Well, the answer is not too difficult to guess. As the amount of CO2 is increasing so is its power to entrap solar radiation and direct it to the earth’s surface. On the other hand, their ability to bounce of a fair share of the radiation, help the human life avoid an unpleasantly hot and unbearable atmosphere. In fact, some countries which have lower temperatures artificially replicate this mechanism to construct greenhouse buildings to create pleasant temperate conditions.It is true that the greenhouse effect is a boon to maintaining the earth’s habitable temperature and has multiple other benefits. Simply because the greenhouse gases are able to entrap the solar radiation and bounce it back to the earth’s surface, is the reason the earth hasn’t frozen yet. ... due to increased CO2 which is problematic. The greenhouse effect has kept the Earth’s average temperature a good deal higher for billions of years, making it possible for life as we know it to evolve. Most climate scientists believe that these changes are linked to a wide range of human activities. Some of the top benefits of greenhouse gases are as follows- How the greenhouse effect functions is a two way process. Additionally, the existence on the polar caps of penguins and polar bears is under deep threat,Photosynthesis, the process by which plants create their own food and in turn initiate the food chain for existence depends upon 3 important elements. In fact doubling of the atmospheric carbon dioxide levels can result in 32% increase in agricultural yields.While the greenhouse effect maintain the temperature, its increase directly translates to rising temperatures. The intensity of hurricanes will be greater due to the greenhouse effect. Secondly, assignments on advantages and disadvantages of greenhouse effect can sensitize students about the need of the hour and help them realize how small steps they take can go a long way to preventing the increase in the greenhouse effect.Imagine a sieve that you use at home to filter milk and dispose off the impurities. Carbon dioxide levels are substantially higher now than at any time in the last 750 000 years. Firstly, being topical in nature, it is important for students to be aware about what is happening at the environmental level. For centuries, this process has been in play to maintain the earth’s temperature. This invariably increases the earth’s temperature.It is a well known fact that oceans absorb CO2 and maintain the alkalinity.
