    apparently Nicole Kidman had some on her leg.

Climatic Hazards Summary
  • Tropical cyclones, hurricanes, typhoons
  • Tornadoes
  • Drought
  • El Nino Southern Oscillation (ENSO) and La Nina
  • The enhanced greenhouse effect (climate change)
  • Acid deposition
  • Ozone depletion
  • Modification of urban micro-climates
  • Modification of rural micro-climates

15
Climatic Hazards Event Key Questions
  • What are the headline facts and figures?
  • When? Where?
  • Why? What are the causes?
  • To what extent are human interactions with
    physical processes responsible for the hazard?
  • How does the hazard affect people and the
    environment?
  • What has been the human response?

16
Factors influencing the impact of climatic hazards
17
How do humans respond to climatic hazards?
18
Forecast vs. Prediction
  • Forecast is a relatively imprecise statement of
    time, place and nature of the expected event
    (Bishop)
  • Prediction is a relatively precise statement of
    the time, place and ideally the nature and size
    of the event, i.e. a precise forecast (Bishop)

19
Risk vs. Vulnerability
  • Risk is the level of exposure of a population to
    a particular hazard.
  • Vulnerability is the ability of a person or
    group to anticipate, cope with and recover from
    the impact of a natural hazard (Blaikie et al
    1994)
