Global Warming is defined as the increase of the average temperature on Earth. As the Earth is getting hotter, disasters like hurricanes, droughts and floods are getting more frequent.Effects of Global Warming: Effects of Global Warming There are two major effects of Global Warming: Increase of temperature on the earth by about 3° to 5° C (5.4° to 9° Fahrenheit) by the year 2100. Rise of sea levels by at least 25 metres (82 feet) by the year 2100. (Melting of land ice)In the last ten years: In the last ten years It is responsible for the increase in: Storms Floods Raging forest fires Other effects ( Malaria returning into areas where it had been controlled earlier, heat waves, tornadoes, higher or lower agricultural yields )PowerPoint Presentation: Global Warming is caused by many things. The causes are split up into two groups: Man-made or anthropogenic causes Natural causes.Natural Causes: Natural Causes Natural causes are causes created by nature. One natural cause is release of methane gas from arctic tundra and wetlands. Methane is a greenhouse gas. Another natural cause is in the earth going through a cycle of climate change. This climate change usually lasts about 40,000 years.Man Made causes: Man Made causes Burning fossil fuel (release of CO2/Methane) Deforestation Industrial production Automobile emissions Mining (When coal /oil is mined, methane is released which occurs naturally in the ground) Other activities (rampant building of concrete structures and expansion of civil habitations)REASONS FOR GLOBAL WARMINNG: REASONS FOR GLOBAL WARMINNG Carbon Dioxide Carbon dioxide is the number-one reason for man-made climate change. Are Governments and business Houses now scrambling to reduce their carbon dioxide emissions ?CO2: CO2 Man-induced increase Since the beginning of the industrial revolution, the average amount of carbon dioxide in the atmosphere has increased by nearly 40 percent from an estimated 280 to more than 380 ppm (Parts per million volume) percent.CO2: CO2 In total, humans emit around 32 gigatons of carbon dioxide each year. Half of this stays in the atmosphere; the rest is absorbed by oceans and vegetation. With sharp increases in man-made CO2 emissions, the natural CO2 cycle gets thrown out of balance: vegetation can no longer transform the increased amount of CO2 into oxygen, and oceans are steadily reaching saturation level.CO2: CO2 carbon dioxide is also produced by the combustion of organic matter like coal , oil , wood, fermentation, and the respiratory process of living organisms.Greenhouse effect: Greenhouse effect What is greenhouse effect? Sun rays enter our atmosphere and shower on our planet. About one third of this solar energy is reflected back into the universe by shimmering glaciers, water and other bright surfaces. Two thirds, however, are absorbed by the Earth, thus warming land, oceans, and atmosphere.Greenhouse effect: Greenhouse effect However, earth also is releasing some energy back into the space thus keeping an equilibrium between the incoming and the reflected energy. This balance maintains temperature of the earth between the average stipulated values.Greenhouse effect: Greenhouse effect Much of this heat radiates back into space, but some of it is stored in the atmosphere. This process is called the greenhouse effect. Without it, the Earth’s average temperature would be a chilling around (-)18 degrees Celsius, even despite the sun’s constant energy supply.PowerPoint Presentation: What are Greenhouse Gases? Many greenhouse gases occur naturally, such as water vapours, carbon dioxide, methane, nitrous oxide, and ozone. Others such as hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6) are produced exclusively from human industrial processes. Human Activities and Greenhouse Gases : Human Activities and Greenhouse Gases Apart from CO2 ,other gases are also released into the atmosphere such as: Nitrous oxide emissions due to various agricultural, industrial processes and also when solid waste or fossil fuels are burned. Apart from being generated naturally from the ground, Methane is emitted when organic waste decomposes, whether in landfills or in connection with livestock farming. Methane emissions also occur during the production and transport of fossil fuels.Protective layer-Ozone : Protective layer-Ozone The ozone layer is a deep layer in the stratosphere , encircling the Earth. The layer shields the entire Earth from harmful UV radiation that come from the sun. Interestingly, it is also this UV radiation that forms the ozone in the first place. Ozone is a special form of oxygen, made up of three oxygen atoms rather than the usual two oxygen atoms. Ozone is a, corrosive, colourless gas which is easily produced by high-voltage electrical arc (spark plugs, Tesla coils, arc welders etc). (10% by Man made activities)Health related issues: Health related issues A number of consequences can result from increased levels of UV (Ultraviolet radiation) striking the earth, including: skin cancer, cataracts and damage to marine life . Increased UV radiation in the lower atmosphere, called the troposphere, can result in increased amounts of photochemical smog which is also a concern in some parts of the world.The culprits : The culprits Use of Chlorofluorocarbons(CFC) propellants in spray cans , hydrofluorocarbons (HFC) and ozone depleting substances (ODS) like halons (used in fire extinguishers),methyl bromide(pesticide),carbon tetrachloride and methyl chloroform ,which are widely used as refrigerants, insulating foams and solvents)OZONE LAYER: OZONE LAYER The ozone layer became more widely appreciated when it was realized that certain chemicals chloroflurocarbons , find their way up into the stratosphere where, through a complex series of chemical reactions, they destroy some of the ozone.The reaction: The reaction When CFCs and HCFCs reach the stratosphere, the ultraviolet radiation from the sun causes them to break apart and release chlorine atoms which react with ozone, starting chemical cycles of ozone destruction that deplete the ozone layer. One chlorine atom can break apart more than 100,000 ozone molecules.Theories of ozone depletion: Theories of ozone depletion Other theories Rockets into space Aircraft cause it to thin. Combustion exhaust and cooling towers Cutting down forests causes it to thin.LETS ACT NOW: LETS ACT NOWPowerPoint Presentation: Easy things to combat climate change……… See the light. Use compact fluorescent light bulbs. These energy-efficient bulbs help fight climate change because they reduce the amount of fossil fuels that utilities burn. You will save 100 pounds of carbon for each incandescent bulb that you replace with a compact fluorescent, over the life of the bulb . Tip -3 Tip -1PowerPoint Presentation: Easy things to combat climate change……… Recycle and use recycled products. Products made from recycled paper, glass, metal and plastic reduce carbon emissions because they use less energy to manufacture than products made from completely new materials. For instance, you'll save two pounds of carbon for every 20 glass bottles that you recycle. Recycling paper also saves trees and lets them continue to reduce climate change naturally as they remain in the forest, where they remove carbon from the atmosphere. Tip -4 Tip -2PowerPoint Presentation: Easy things to combat climate change……… Plant native trees . Trees absorb carbon dioxide from the air and use it as their energy source, producing oxygen for us to breathe. A tree in the temperate zone, found between the tropics and the polar circles can remove and store 700 to 7,000 pounds of carbon over its lifetime. A tree that shades a house can reduce the energy required to run the air conditioner and save an additional 200 to 2,000 pounds of carbon over its lifetime. Tip -5 Tip -3PowerPoint Presentation: Easy things to combat climate change……… Turn down the heat . Heating and air conditioning draw more than half of the energy that a home uses. Turn down the heat or air conditioning when you leave the house or go to bed. You can easily install a programmable thermostat that can save up money and carbon . Tip -6 Tip -4PowerPoint Presentation: Easy things to combat climate change……… Buy renewable energy . Electricity generation produces 40 percent of carbon emissions. A growing number of utilities generate electricity from renewable energy sources with solar panels, windmills and other technologies .

Reduce Your FoodprintPowerPoint Presentation: " Think.Eat.Save . Reduce Your Foodprint Mexico is going to Host World Environment Day under this Theme Theme for World Environment Day 5 th June 2013PowerPoint Presentation: World Environment Day 2013 World Environment Day is celebrated every year on 5 June in more than 100 countries. World Environment Day (WED) was established by the United Nations General Assembly in 1972 . WED is hosted every year by a different city and commemorated with an international exposition through the week of June 5. The United Nations Environment Programme (UNEP ) also created in 1972, uses WED to stimulate awareness of the environment and enhance political attention and public action.PowerPoint Presentation: The 2013 theme for World Environment Day is Think.Eat.Save ., with host country Mongolia. Think.Eat.Save is an anti-food waste and food loss campaign that encourages you to reduce your foodprint . According to the UN Food and Agriculture Organization (FAO), every year 1.3 billion tons of food is wasted. This is equivalent to the same amount produced in the whole of sub-Saharan Africa. 1 in every 7 people in the world go to bed hungry and more than 20,000 children under the age of 5 die daily from hunger. World Environment Day 2013PowerPoint Presentation: World Environment Day is a people’s event with colourful activities such as street rallies, bicycle parades, green concerts, essays and poster competitions in schools, tree planting as well as recycling and clean-up campaigns. World Environment Day is also a multi-media event which inspires thousands of journalists to write and report enthusiastically and critically on the environment. It is a visual event for those who organize and participate in seminars, round table meetings and symposia. On this day, individuals, non-governmental organizations, community and youth groups, business, industry and the media organize activities to renew their commitments to protect and develop the environment. They organize activities such as clean-up campaigns, tree planting, colourful street rallies, green concerts, essay and photo competitions in schools and recycling efforts. How we can Celebrate the Day……………….PowerPoint Presentation: What is meant by ……. Think.Eat.Save . Reduce Your Foodprint Think.Eat.Save – encourages you to become more aware of the environmental impact of the food choices you make and empowers you to make informed decisions. While the planet is struggling to provide us with enough resources to sustain its 7 billion people (growing to 9 billion by 2050), FAO estimates that a third of global food production is either wasted or lost. Food waste is an enormous drain on natural resources and a contributor to negative environmental impacts.PowerPoint Presentation: World Environment Day 2013 World Environment Day This year’s campaign rallies you to take action from your home and then witness the power of collective decisions you and others have made to reduce food waste, save money, minimize the environmental impact of food production and force food production processes to become more efficient. If food is wasted, it means that all the resources and inputs used in the production of all the food are also lost. For example, it takes about 1,000 litres of water to produce 1 litre of milk.Theme for World Environment Day 5th June 2013: Theme for World Environment Day 5 th June 2013WHAT IS REQUIRED TO BE DONE ?
