Sea levels have risen almost one footAIM: AIM To acquaint the class about “Global Warming” and discuss measures to be taken to Save the EarthPREVIEW: PREVIEW Part – I Understanding Global Warming Part – II Understanding Greenhouse Effect & Ozone Layer Depletion Part – III Causes G lobal Warming Part – IV Effects of Global Warming PART – V Solutions PART – VI Helping Hand by NCCWhat is this Global Warming: What is this Global Warming Global warming is when the earth heats upCauses - Global Warming: Causes - Global Warming Green House Effect Ozone Layer DepletionGreen House Effect: Green House Effect It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. Nitrous oxide Water Carbon dioxide Sulfur hexafluorideWhy it happens?: Why it happens? Burning carbon-containing fossil fuels produces carbon dioxide 37%PowerPoint Presentation: Nitrous oxide from fertilizers and other chemicalsOzone Layer Depletion: Ozone Layer Depletion Ozone is present in the stratosphere. The ultra violet rays of sun are absorbed by the ozone in the stratosphere and protects the Earth from the harmful ultraviolet raysOzone Layer Depletion - Causes: Ozone Layer Depletion - Causes The production and emission of CFCs, chlorofluorocarbons which are used in refrigerators, home insulation, plastic foam, and throwaway food containers.Global Warming - Effects: Global Warming - E ffects June 2002 Dec 2003 Colorado River, ArizonaGlobal Warming - Effects: Global Warming - E ffects June 2002 Dec 2003 Colorado River, ArizonaGlobal Warming - Effectss: Global Warming - E ffects s 1914 2004 Portage Glacier, AlaskaGlobal Warming - Effects: Global Warming - Effects Geographical effects Climate change Wildlife humansPowerPoint Presentation: The Arctic Ocean could be ice-free in summer by 2040 (U.S National Center for Atmospheric Research, 2006) “Society can still minimize the impacts on Arctic ice.” Dr. Marika Holland, National Center for Atmospheric Research 2000 2040 Melting Sea IcePowerPoint Presentation: Sea-level rise projections : a few inches to a few feet 2 ft: U.S. would lose 10,000 square miles 3 ft: Would inundate Miami Affects erosion, loss of wetlands, freshwater supplies Half of the world’s population lives along coasts Big question: Ice sheetsPowerPoint Presentation: As the temperature of oceans rise, so will the probability of more frequent and stronger hurricanes . Warmer waters and more hurricanesPowerPoint Presentation: Increased probability and intensity of droughts and heat wavesPowerPoint Presentation: Increase in frequent volcanic eruptions due to rise in temperaturesPowerPoint Presentation: Forest fire increased due to hot windsWildlife effects: Wildlife effectsEffects on human beings: Effects on human beingsPowerPoint Presentation: Human Health - S pread of disease As northern countries warm, disease carrying insects migrate north, bringing swine flu and other disease with them.Human Health and Agriculture: Human Health and Agriculture Agriculture – Main Source of Income Factors endangering the crops Precipitation Evaporation More People are going to starve 40-300 million people in addition to the 600 million already projected to be starving in 2060Human Health and Water Supply: Human Health and Water Supply With inc of annual precipitation and the amount of ice converted to freshwater from the polar ice caps there will be increased sea level 2100 of as 40 centimeters Rise in sea level will destroy human dwellings Places of agricultural production Sea-side aquifers resulting in depletion of general water supply for humankindHuman Health and Air Conditions: Human Health and Air Conditions The amount of smog that is created by nitrous oxide, the ground, will increase resulting in the fatally warm summer days increase the potential of lung infection which can lead to deathWhat can we do? - solutions: What can we do? - solutions HIGH TIME TO BE ALARMEDAdvantages of 3R’s: Advantages of 3R’s Reduction of wastages Less pollution Efficient use of resources Increase in energyPowerPoint Presentation: REDUCE USE Plastic bags and cups do not decompose so harmful to environment Paper bags and cups are eco friendly and easily decomposable Reduce the usage of cars for short distances Walk /use cycles for short distancesPowerPoint Presentation: Avoid turning up the air conditioner. Instead dress lightly or use a fan. Keep rooms cool by closing the blinds, shades, or curtains. Turn off the lights when you leave. Conserve electricity! DO NOT leave appliances on standbyPowerPoint Presentation: Turn to compact florescent light which saves more than 80% of energyPowerPoint Presentation: Use alternate energy courses Alternate energy sources Nuclear Wind Geothermal Hydroelectric Solar FusionNCC INITIATIVE: NCC INITIATIVE Creating awareness amongst the Cadet Awareness in the Parents One Cadet One treeTree Plantation Awareness Rally Earth day – 22 Apr Save the Electricity – 27 FebruaryTHE MAIN THING ONE CAN DO TO STOP GLOBAL WARMING IS TO BRING A CHANGE IN ATTITUDE AND BEHAVIOR. ONLY THEN WILL WE SURVIVE.: THE MAIN THING ONE CAN DO TO STOP GLOBAL WARMING IS TO BRING A CHANGE IN ATTITUDE AND BEHAVIOR. ONLY THEN WILL WE SURVIVE.PowerPoint Presentation: TRY TO SAVE OUR PLANET You do not have the permission to view this presentation. In order to view it, please contact the author of the presentation.
