    1. OUR FRAGILE PLANET EARTH Planet Earth may be at greater risk than ever before with the emergence of global warming and global climate change as possible future threats Walter Hays, Global Alliance for Disaster Reduction, University of North Carolina, USA

    2. PLANET EARTH IS WARMING UP AS A RESULT, LOCAL AND REGIONAL CLIMATES ARE LIKELY TO CHANGE LEAVING MANY CITIES WITH ENVIRONMENTS AT HIGHER RISK, ESPECIALLY FROM WEATHER-RELATED NATURAL HAZARDS

    3. AS A RESULT OF GLOBAL WARMING, - - - • Sea level will rise. • Coastal areas will be flooded • The frequency and intensity of severe windstorms may increase, with an associated increase in flooding from storm surge and rainfall and mudslides. • The frequency of wildfires may increase • Winter storms may be more intense

    4. AS A RESULT, EARTH’S ENVIRONMENTS ARE LIKELY TO BE AT HIGHER RISK • Oceans • Polar regions • Deserts • Grasslands • Wetlands • Mountains • Forests • Cities

    5. Possible Changes in Earth’s Polar Regions Warming of Planet Earth due to the apparent warming will likely cause: • Melting of polar ice caps, glaciers, and pack ice

    6. GREENLAND

    7. NORTHWEST TERRITORIES, CANADA

    8. WENGEN, SWITZERLAND

    9. KANAI FJORD, ALASKA

    10. SOUTH GEORGIA ISLAND

    11. MT KILIMANJARO, TANZANIA

    12. NORTHEAST USA: 1 METER RISE IN SEA LEVEL

    13. MANHATTAN ISLAND, NEW YORK CITY: AT RISK

    16. THE NETHERLANDS

    17. VENICE, ITALY

    18. HALONG BAY, VIETNAM

    19. FUNAFUTI,TUVALU

    20. Possible Changes in Earth’s Environments When Planet Earth receives more water in a short period than can be contained in the floodplains and wetlands, the result is: • Flooding

    21. Floods in Mozambique

    22. Planet Earth’s coasts are subjected to severe windstorms with large waves, storm surge, and heavy rainfall--large quantities of water, which cause: Drastic irreversible changes along the coast lines. Possible Changes in Earth’s Environments

    23. HURICANE KATRINA: NEW ORLEANS UNDER WATER, 2005

    24. HURRICANES DESTROY BARRIER ISLANDS

    25. TROPICAL STORM NOEL 235 MILES SW OF NASSAU: OCT 31, 2007

    26. 70 % OF MEXICO’S TABASCO STATE UNDER WATER: NOV 2, 2007

    27. TROPICAL STORM NOEL: HAITI, OCT 30, 2007

    28. Possible Change in Earth’s Environment As Planet Earth warms up, • Desertification Increases

    29. 1/6 OF WORLD’S POPULATIONS AFFECTED BY DESERTIFICATION

    30. Possible Changes in Earth’s Environment As Planet Earth warms up, • Dust Storms may Increase

    31. DUST STORM: AL ASAD, IRAQ: APRIL 27, 2007

    32. Natural Phenomena that Change our Environment Planet Earth is warming up, causing: • Droughts

    33. DROUGHT IN CHINA: 2007

    34. Possible Changes in Earth’s Environment As Planet Earth warms up, • Rivers may dry up.

    40. WILDFIRES IN SOUTHERN CALIFORNIA: OCTOBER 21,2007

    41. Planet Earth is easily damaged by some of man’s actions, for example: Deforestation Possible Changes in Earth’s Environment

    42. 1 ½ ACRES OF RAIN FOREST DISAPPEAR EVERY SECOND

    43. Implications for Planet Earth The potential risk to Planet Earth’s environments calls for: • Public policies that promote long-term community resilience

    44. FOUR PILLARS OF RESILIENCE • NATURAL HAZARDS • INVENTORY • VULNERABILITY • LOCATION • PREPAREDNESS • PROTECTION • EMERGENCY RESPONSE • RECOVERY IENCE RISK ASSESSMENT ACCEPTABLE RISK RISK UNACCEPTABLE RISK GOAL: DISASTER RESILIENCE DATA BASES AND INFORMATION COMMUNITY HAZARDS: GROUND SHAKING GROUND FAILURE SURFACE FAULTING TECTONIC DEFORMATION TSUNAMI RUN UP AFTERSHOCKS

    45. COMPREHENSIVE PUBLIC POLICIES MONITORING

    46. Protecting Planet Earth Planet Earth’s changes in exposure and risk over time call for: • Technology to monitor the causative factors, warn people, and protect property, and infrastructure.

    47. POLICIES FOR REDUCTION OF RISK • MONITORING (TRACKING CHANGES THAT MIGHT INCREASE THE RISK TO A CITY AND WARNING THE PEOPLE IN TIME FOR THEM TO GET OUT OF HARM’S WAY) AND PROTECT PROPERTY
