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
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
AS A RESULT, EARTH’S ENVIRONMENTS ARE LIKELY TO BE AT HIGHER RISK • Oceans • Polar regions • Deserts • Grasslands • Wetlands • Mountains • Forests • Cities
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
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
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
Possible Change in Earth’s Environment As Planet Earth warms up, • Desertification Increases
Possible Changes in Earth’s Environment As Planet Earth warms up, • Dust Storms may Increase
Natural Phenomena that Change our Environment Planet Earth is warming up, causing: • Droughts
Possible Changes in Earth’s Environment As Planet Earth warms up, • Rivers may dry up.
Possible Changes in Earth’s Environment As Planet Earth warms up, • Wildfires may Increase
Planet Earth is easily damaged by some of man’s actions, for example: Deforestation Possible Changes in Earth’s Environment
Implications for Planet Earth The potential risk to Planet Earth’s environments calls for: • Public policies that promote long-term community resilience
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
COMPREHENSIVE PUBLIC POLICIES MONITORING
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.
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
