    • WELCOME to An Overview PRESENTATION on “ GLOBAL WARMING ” by P.Praveen Kumar
    • GLOBAL WARMING
    • Some Inconvenient Truths… Mumbai’s Nariman Point will be submerged by Year 2020 40% of Himalayan glaciers would vanish by Year 2035   50 million people in coastal belt will be displaced by year 2100         
    • Some Inconvenient Truths…
      • There is not enough time left , just 8 years to save the planet…
      • - Times of India, 8th May, 2007
      • These are not sayings of traditional monks or saints but by IPCC ( Intergovernmental Panel on Climate Change)-a UN body represented by 105 countries comprising of 30 of the world’s top scientists .
    • What is Global warming ?
      • Global warming -- a gradual increase in planet-wide temperatures
      • Earth has been hottest in at least 400 years, and possibly even the last 2,000 years.
      • Studies indicate that the average global surface temperature has increased by approximately 0.5-1.0°F (0.3-0.6°C) over the last century.
      • This warming is largely attributed to the
      • increase of greenhouse gases in the
      • Earth's upper atmosphere.
    •  
    • Earth’s temperature rise
      • In the year 1905- the average temperature of planet is 14 0 C has increased 2.5% an unusual rapid increase rate of 0.35 0 C.
      • Over the last 25 years, from 1970 to 2005, it went up to 4% (or 0.55 o C).
      • total increase in global average temperature represents a rise of 5.4% (or 0.74 o C) since 1750.
      • The key point is that especially since 1990, is that of a consistent, increasingly and unusually rapid, increase in global average temperatures.
    • IPCC Report states ..
      • Global warming is now Clear that human activity “very likely” has been the primary cause of rising temperatures worldwide since 1950.
      • The report summary also says that global warming is likely to continue for centuries, and that it is already too late to stop some of the serious consequences it will bring—even if mankind could somehow hold the line on greenhouse gas emissions worldwide starting from today.
    • GREEN HOUSE GASSES
      • The gas traps heat more effectively than all other gasses are known as Green house gasses, These will occur naturally in the environment and also result from human activities.
      • These gasses are:
      • Carbon Monoxide
      • Carbon dioxide
      • Nitrous oxide
      • Oxides of Sulphur
      • Methane gas
      • CFC gases
    • Carbon Monoxide Carbon monoxide is colorless, odorless and tasteless, but highly toxic. It combines with hemoglobin to produce carboxyhemoglobin , which is ineffective for delivering oxygen to bodily tissues.
    • Carbon dioxide ( Co 2 )
      • Next most abundant greenhouse gas that flows into atmosphere from many processes such as:
      • Burning of fossil fuels, solid wastes & wood products, gasoline vehicles, generation of electricity, deforestation (huge cutting of trees)
      • Volcanic eruptions
      • The respiration of human being which inhales oxygen & exhales CO 2
    • CO 2 Emissions to atmosphere
      • In the year 1750 about 281 molecules of CO 2 parts per million molecules in air ( ppm)
      • Today it is 390 ppm in air which reflects the increase of 33% CO 2 concentration in an atmosphere.
      • If current status prove accurate, by the year 2100 , CO 2 will reach concentrations of more than 970 ppm (this figure would be triple the levels prior to the industrial revolution).
    •  
      • A powerful insulating gas released primarily by burning fossil fuels. Nitrous oxide traps about 300 times more heat than does the same amount of CO 2 . The concentration of nitrous oxide in the atmosphere has increased 17% over pre-industrial levels.
      Nitrous oxide
    • Oxides of Sulphur
      • Sulfur dioxide (SO 2 ) results from the combustion of fuels containing sulfur or sulfurous chemicals.
      • If the SO 2 oxidizes in the atmosphere to sulfur trioxide (SO 3 ) it can combine with water to form sulfuric acid (H 2 SO 4 ) with stronger environmental chemical reactions.
      • If it happens it erode ionic balance of clay soils (Not useful to grow plants), it fade paints and change the pH of river and lake water which will harm the aquatic animals and organisms.
      • Methane gas is 23 times more efficient in trapping heat in the atmosphere than carbon dioxide.
      • Since the beginning of the industrial revolution , the amount of methane in the atmosphere has more than doubled.
      • 4 main sources to produce methane gas is  livestock( growing animals for meat) and livestock manure, rice farming , coal mining and landfills are the major sources of CH 4 emissions.
      Methane gas
    •  
      • In recent years it has been found that CFCs are most destructive to the environment.
      • It has been proved that CFCs are a major cause of depletion of the earth’s stratospheric ozone layer and contribute to the greenhouse effect (global warming).
      • The most shocking fact about CFCs is that they have exceptionally long atmospheric life which, in certain cases, even extends to 100 years.
      • The chlorine atom removed from CFCs reacts with ozone molecule (O 3 ) and converts it into oxygen molecule (O 2 ).
      • oxygen does not have the capacity to filter the highly intense ultraviolet radiations. Due to this the amounts of ultraviolet rays reaching the surface of the earth becomes very high and then causes excessive heating in the environment, called the Green house effect.
      Chlorofluorocarbons (CFCs):
    • IMPACT OF GLOBAL WARMING
      • As per scientists’ prediction the warmed world will be more humid & hot which will result in more water evaporation from earth.
      • Humid weather will enhance rainfall but with change pattern & high intensity.
      • Storm will be more strong & frequent.
      • Weather pattern are suspected to be less predictable and more extreme.
      CLIMATE
    • Melting Ice in the Arctic 1980 2002 2003 2004 2004 2002 2003 1980
      • Sea level world wide rose 10-20 cm in 20th century
      • In 21st century IPCC predicts a rise of 9 to 88 cm .
      • It will submerge 6% of Netherlands, 17.5% of Bangladesh and many Island will disappear.
      SEA LEVEL
    • AGRICULTURAL EFFECTS
      • Increase in temperature may cause a pole-ward Shift of agricultural zones and shift in growing seasons.
      • Equatorial zones, where agriculture is generally unproductive now, will deteriorate further.
      • In many areas currently fertile, like parts of south America, New Zealand, and Southern Africa, condition are Predicted to become more arid and crop yields to become more marginal.
      • Animals and plants will find difficult to escape or adjust to effect of warming because of less availability of space already occupied by human population.
      Effect on Animals
      • Approximately 20-30% of plants and animal Species assessed so far are likely to be at greater risk of extinction if increases in global Average temperature exceed 1.5 to 2.5 Celsius.
      • As per IPCC, more people will get sick or die from heat stress due to warmer nights.
      • Today 45% of world population is affected by mosquito carrying parasites. The percentage may increase to 60 if temperature rise rate remains same till 2030. Other diseases e.g. dengue fever, yellow fever and encephalitis will increase rapidly.
      • Allergies & respiratory disease grow as warmer air grows as it will be more charged with pollutants.
      Effects on Human health
    • EFFECT OF GLOBAL WARMING ON INDIAN CONTEXT
    • 30% Drop in per capita water availability by 2030 for Indians as a result a great dries become frequent.
    • Sudden and Violent Change at coastal:- sea level will rise 40 cm higher by 2100 and 50 million people in coastal India would be displaced by flooding
    • Wheat production will fall by 17% in India if the temperature rise by even half-a degree centigrade
    • The Himalayan glaciers may totally disappear causing catastrophic disruption
    • THE GLACIER MELT DOWN WILL FIRST RESULT IN RIVERS BEING FLOODED AND THEN DRYING UP.
      • WARMER OCEAN TEMPERATURE WOULD LEAD TO BLEACHING AND DESTROY VAST TRACTS OF INDIAN CORAL REEFS
      • OCEAN ACIDIFICATION WOULD LEAD TO SHELL DISSOLUTION, SEVERELY IMPACTING MARINE LIFE AND FISHERIES
    • 25% AMOUNT OF FLORA & FAUNA IN INDIA WOULD EXTINCT BY THE YEAR OF 2030.
    • What will we do as an individual… ???
      • R ecycle paper , plastic , newspaper, glass and aluminum cans.
      • By recycling half of your household waste, you can save 2,400 pounds(1088.6Kgs) of carbon dioxide annually.
      Reuse & Recycle
    • Use Less Heat and Air Conditioning
      • Setting your thermostat just 2 degrees lower in winter and higher in summer could save about 2,000 pounds(907.1Kgs) of carbon dioxide each year.
    • Change a Light Bulb
      • CFLs last 10 times longer than incandescent bulbs, use two-thirds less energy, and give off 70 percent less heat.
      • If every family in India replaces one regular light bulb with a CFL, it would eliminate 900 billion pounds of greenhouse gases, the same as taking 27.5 million cars off the road.
    • Use the "Off" Switch
      • Save electricity and reduce global warming by turning off lights when you leave a room, and using only as much light as you need.
      • And remember to turn off your television, video player, stereo and computer when you're not using them.
    • As an organization Change technology : Improve efficiency, use green energy, Utilize renewable energy and live without compromising
    • Drive Less and Drive Smart
      • Less driving means few emissions.
      • When you do drive, make sure your car is running efficiently
      • Every gallon of gas you save not only helps your budget, it also keeps 20 pounds(9.0Kgs) of carbon dioxide out of the environment .
    • Buy Energy Efficient Products
      • Home appliances now come in a range of energy efficient products
      • Avoid products that come with excess packaging, especially molded plastic and other packaging that can't be recycled. If you reduce your household garbage by 10 percent, you can save 1,200 pounds(544.3Kgs) of carbon dioxide annually.
    • Switch on from Non- Veg. to Vegetarian diet
      • The world’s top destroyer of the atmosphere is not the car or the factory – it is the meat eating human.
      • If you stop eating meat , you will stop the Gangetic glacier from melting and the Ganges  river will stop turning into a stream.
      • Take the power into your own hands.  You do not need machines or governments or international treaties. You can stop it today by yourself.
      The quickest way to stop the climate changing is by turning vegetarian. How simple it is. May be this is the ultimate lesson that nature is trying to teach us. Wickedness brings sorrow. Don’t kill and Don’t be killed. -Dr Rajendra Pachauri (Head of IPCC)
      • Each tree planted ‘offsets’ our environmental impact by ‘breathing’ in about 1 tonne of CO 2 emissions over its lifetime of 100 years. It is estimated that the average person needs to save about 7,000 kg of CO 2 per year. So planting just 7 trees each year by a single individual is one strategy for achieving this.
      Plant a Tree
      • Nature has given enough for every body's need but not for everybody’s greed .
      • -M.K. Gandhi
    • We will not be able to get the outer world in order, until we have first learned to get our inner world in order. Brahmakumaris’ Opinion at Johannesburg during UN meet
    • Mental Pollution Wars are not fought on battle fields but are first fought in minds.
      • THINK CLEAN, THINK GREEN!
      • Outer nature is a reflection of Inner nature
      • Inner Harmony is essential for outer Harmony
    • The Law of the Mind states that: Plant a thought, harvest a FEELING ; Plant a feeling, harvest an ACTION ; Plant an action, harvest a HABIT ; Plant a habit, harvest a CHARACTER ; Plant a character, harvest a DESTINY . PLANT A SEED OF THOUGHT
    • What We Want ? Choice is OURS ? A Planet- Peaceful A Planet-Devastated
    • LET’S DREAM AND WORK TOGETHER FOR A GREEN WORLD
    • Let’s stretch our hands to protect our planet right from this moment Save me Please!
    • LET’S GIFT A CLEAN AND GREEN PLANET TO OUR FUTURE GENERATION, SO THAT THEY CAN CHERISH Life is God’s Gift, and how we make it a gift to God
    • Any Questions Please ??
