  • From 1900 to 2005, precipitation increased significantly in eastern parts of North and South America, northern Europe and northern and central Asia but declined in the Sahel, the Mediterranean, southern Africa and parts of southern Asia. Globally, the area affected by drought has likely increased since the 1970s. {1.1} SYR SPM p.1 More intense and longer droughts have been observed over wider areas since the 1970s, particularly in the tropics and subtropics. WG1 {3.8, 3.9} (SPM p.8) About 25% of Africa’s population (about 200 million people) currently experience high water stress. WG2 Chap 9 p.435

    2. 2. Global Warming is the increase of Earths average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth. This is a type of greenhouse effect./
    3. 3. Why is global warming happening? Pollution from coal, natural gas, and oil
    4. 4. Carbon Dioxide (CO2)Fossil fuels (coal, oil, natural gas)
    5. 5. Rising Sea Level Increased TemperatureHabitat Damage and Changes in Water Supply
    6. 6. Example of the Greenhouse Effect The Sun’s energy passes through the car’s windshield.This energy (heat)is trapped insidethe car and cannotpass back throughthe windshield,causing, the insideof the car to warmup.
    7. 7. This is where temperature have risen in the world.
    8. 8. How is global warming measured? Ice Core Data CO2 Measurements Before 1958 - Antarctica
    9. 9. The yellow represents warming, melting glaciers, flooding andrising of sea level. The red represents the spread of disease,earlier springs and population changes, heavy snowfalls, andflooding, droughts and fires.

    11. 11. The frequency of heavy precipitation events have increased over most land areas - Rainfall in Mumbai (India), 2005: 1 million people lost their homes
    12. 12.  “Penguin population decline. Penguin population have shrunk by 33% during the past 25 years in response to declines in their winter sea ice habitat.”
    13. 13. Fuel-Efficiency Solar PowerWind Power
    14. 14. What can you do to help solve the problem?
    15. 15. Turn off your computer or the TV when you’re not using it.Take shorter showers. Heating water uses energy. Keep rooms cool by closing the blinds, shades, or curtains.Turn off the lights when you leave a room. Use compact fluorescent bulbs.
    16. 16. What’s the CompactIncandescent difference? Fluorescent 500 lbs. of coal •1,430 lbs. CO2 pollution avoided •$30 saved
    17. 17. Dress lightly when it’s hot instead of turning up the air conditioning Or use a fan.Dress warmly when it is cold instead of turning up the heat. Offer to help your parents keep the air filters on your AC and furnace clean. Walk short distance instead of asking for a ride in the car. Plant a tree. Recycle.
    18. 18. Global warming is affecting plants,animals, humans and the earth. We need tolearn how to conserve our use of fossilfuels to minimize carbon dioxideproduction. This will slow down the effectsof global warming.
