    • The Media and Hollywood: Raising Awareness about Natural Disasters and Climate Change

    • Earthquakes Volcanoes Tornadoes
    • Hurricanes Floods Droughts
    • Winter Storms Wild Fires Thunderstorms
    NOAA 2007.
  • 4. Natural Disasters throughout History
  • 5. Frozen River: Thames
    • As early as 260 AD there are records showing that the River Thames in London froze regularly until it was embanked in the 19 th century.
    • Many deaths of people, flora and fauna were attributed to this condition even though joyous fairs were held upon the frozen surface. It last froze in 1814.
  • 6. FIRE !!!!
    • On 8 October 1887, in Peshtigo, Wisconsin, over
    • 1500 lives were lost, and over 3.8 million acres
    • burned in a forest fire.
  • 7. Winter Storms
    • The ‘Blizzard of 1888’ hit the East Coast in March, leaving 40 people dead, accumulations up to 5 feet.
    • Damage estimated at $20 million ($2 billion today ?)
  • 8. Floods
    • May 1889 in Johnstown, Pennsylvania: the collapse of the South Fork Dam left more than 2000 dead.
  • 9. Avalanche
    • 1 March 1910 in Wellington, Washington, 2 trains, snowbound at Stevens Pass in the Cascade Range, were swept off the tracks into a canyon 150 feet below, killing 56.
  • 10. Tornado
    • March 18 1925 in Missouri, Illinois and Indiana, the great “Tri-State Tornado”.
    • 689 dead, over 2000 injured, property damage estimated at $16.5 million.
  • 11. Drought
    • The drought of the 1930s was the longest drought of the 20 th
    • century. During 1934, dry regions stretched solidly from NY
    • and PA across the Great Plains to California coast. The great
    • “ dust bowl” covered 50 million acres on the south central
    • plains during the winder of 1935-36.
  • 12. 1900 Galveston Hurricane
    • 4 th September 1900: a tidal surge due to a
    • hurricane killed 6000-8000 Galvestonians.
  • 13. Trinity River Flood
    • Envisioned as a shipping canal from the Gulf of Mexico to Dallas.
    • Heavy rains on 17 th May 1949 caused the levees of the West Fork and Clear Fork to fail - leading to the loss of 10 lives.
  • 14. Costs of Natural Disasters
  • 15.  
  • 16. Facts & Figures – Natural Disasters
    • The costs are now 15X higher than they were in the 1950s.
    • Number of disasters has grown: fewer than 100 in 1975 to more than 400 in 2005.
    • Approx. 2.6 billion people were affected by natural disasters over the past 10 years, compared to 1.6 billion the previous decade.
  • 17. Financial Support – World Bank
    • 528 projects in the past
    • 20 years
    • $42,552 million in commitments
    • $26,281 million in
    • activities
    • Over 80% of the bank’s
    • disaster financing has addressed floods, earthquakes, and fires.
  • 18. Top 10 Surprising Results of Global Warming
    • Aggravated allergies ; warm temp. and CO2 effect plants to bloom early = more pollen.
    • Heading for the Hills ; mammalia species to higher elevation due to change in habitat.
    • Arctic in Bloom ; booming of Artic biota no longer trapped in ice.
    • Pulling the Plug ; 125+ lakes in the Artic have disappeared.
    • The Big Thaw ; layers of permanently frozen soil thawing out.
    • Survival of the fittest ; plants bloom earlier in the year, animals that wait until their usual time to migrate might miss out on all the food.
    • Speedier Satellites ; due to CO2 sparsed molecules in upper atmosphere will collide less frequently and tend to radiate energy away cooling the atmosphere allowing air to settle = less dense air = less drag on satellite orbit.
    • Rebounding Mtns ; Glaciers melting, the weight of mountains are lifting and surface slowly springing back. (i.e. Alps)
    • Ruined ruins ; natural disasters damaging irreplaceable sites.
    • Forest fire frenzy! Western U.S. office.

  • 19. Impact of Greenhouse Gas Emissions and Climate Change on Natural Disasters
  • 20. Francis and Hengeveld (1998)
  • 21. Theory: Greenhouse Gas Emissions and Climate Change
    • Alter the intensity and frequency of natural disasters
    • that are regulated by atmospheric and oceanic conditions
    • Yes: hurricanes and cyclones, droughts, floods, thunderstorms, wild fires, winter storms
    • No: volcanoes, earthquakes
    • Maybe: tornadoes (no decisive verdict yet)
    • Ok, but how?
  • 22. Different Mechanisms for Altering Natural Climatic Processes
    • Altering distribution of heat and energy; thereby, altering circulation patterns of the atmosphere and oceans (ex: thermohaline circulation)
    • Altering hydrological cycle: increased convection over warmer land and sea surfaces; warmer air holds more moisture that will fall down as precipitation
    • Example: Hurricanes and Tropical Storms need Sea Surface Temperatures of 27 ° C or more
  • 23. Changes in Sea and Land Surface Temperature NOAA 2007.
  • 24. Changes in Sea and Land Surface Temperature NOAA 2007.
  • 25. Francis and Hengeveld (1998)
  • 26. Changes in Precipitation NOAA 2007.
  • 27. Changes in Precipitation Francis and Hengeveld (1998)
  • 28. Changes in Precipitation Francis and Hengeveld (1998)
  • 29. Changes in Precipitation Francis and Hengeveld (1998)
  • 30. Possibly Aggregating the Problem: Milankovitch Cycles Brown and Lomolino (1998)
  • 31. Definitely Aggregating the Problem: Urbanization
    • Daniel Sarewitz and Roger Pielke, Jr.:
    • reduction in greenhouse gas emission is
    • important but will not reduce vulnerability to
    • natural disasters. Why?
    • Urbanization: More people living closer to coast and flood prone areas
  • 32. Results: Increased Frequency and Intensity of Climate Anomalies NOAA 2007.
  • 33. NOAA 2007.
  • 34. NOAA 2007.
  • 35. The Media and Hollywood: Raising Awareness about Natural Disasters and Climate Change
  • 36. Climate Change and Natural Disasters in Movies
    • Grapes of Wrath Twister
    • The Perfect Storm Absolute Zero
    • Day After Tomorrow Volcano
  • 37. Relevance of Mass Media to Disaster Management
  • 38.
    • Started by Laurie David, wife of Larry David (co-creator of Seinfeld and creator of Curb Your Enthusiasm)
    • A virtual march that is a non-political effort bringing Americans together to declare that global warming is here now and it’s time to act.
    • Videos include Leonardo DiCaprio, Martin Short, Robert F. Kennedy, Jr.
    “ Join the 670,948 supporters of the Stop Global Warming Virtual March, and become part of the movement to demand solutions to global warming now.”
  • 39. HBO Documentary
    • “ Heat waves. Melting glaciers. Rising sea levels. Catastrophic storms. Migrating viruses. Population displacement. Over the past 100 years, the mass consumption of fossil fuels, especially in America, has contributed to a dangerous warming of the earth that has adversely impacted the way we live. The cautionary documentary offers a guide to the effects of global warming in the United States. “
