2 Outline Introduction Definition Greenhouse means? Greenhouse Gases. The changes in the atmosphere’s concentration of greenhouse gases can affect the Earth's temperatureHow does Greenhouse Effect occur?Negative effectsHypotheses about the Greenhouse EffectEffects of Global Warning on LifePossible solutions: How to reduce The Green House Effect?Conclusion
3 The Green House EffectThe greenhouse effect is a term that describes how natural gases in the earth's atmosphere reduce the amount of heat escaping from the earth into the atmosphere.The more of these gases there are, the more the Earth heats up.
4 Greenhouse means? Most greenhouses look like a small glass house. Greenhouses are used to grow plants, especially in the winter.
5 Greenhouse Gases Water vapor Carbon dioxide (CO2) Methane (CH4) Nitrous oxide (N2O)Carbon monoxideOzoneHalocarbonsSmoke and Dust
6 Carbon Dioxide in the atmosphere Photosynthesis balance to keep the amount of atmospheric carbon relatively stable.Industrialization, has contributed additional carbon dioxide to the environment.
7 How does Greenhouse Effect occur? Solar energy is absorbed by the Earth and the oceans.Reradiates back on out into the atmosphere, into stratosphere.The burning of fossil fuel create a veil in the atmosphere
8 Negative EffectsDroughts in most of the agricultural areas in the world.
9 Negative EffectsThe melting of the polar ice caps and subsequent flooding of coastal areas.
10 Hypotheses about the Greenhouse Effect. The Global Warming is taking place.The Global Cooling is going to occur.Neither Global Warming nor Cooling will occur or has been occurring.
11 Effects of Global Warning on Life Climate Change and global WarmingRise of sea LevelIncrease of diseaseEnvironmental ChangingIncrease of natural disasters
12 How to reduce the Greenhouse Effect BY THE GOVERNMENT:Stabilization of the population growth.Reduction of air pollution from industries (international agreements)Reduction of desertification and protection of the rainforest against the clearance (national programs)Finding alternative fuel
13 How to reduce the Greenhouse Effect BY PEOPLE:Reduce the use of fossil fuelStop the clearance of the forestFollow the recommendations to reduce the emission of Greenhouse gases.
14 How to reduce the Greenhouse Effect BY USBe well inform about the consequences of Greenhouse EffectChange your lifestyle habits to help save the environmentPlant trees.Eliminate the use of CFCs
15 ConclusionCutting down forest and burning fossil fuels create more CO2 in the air.When there are more greenhouse gases, more heat is radiated towards Earth’s surface, this produce Global warming.Even global temperature changes of less than 1 degree can cause problems, like sea level rise and changes in rainfall.Find solutions such as: reduce population, reduce air pollution, stop desertification.
