Week 7: Extreme Weather

Disasters
1. Increase in frequency
2. Cost increase as frequency increase
3. Vulnerability increases with poverty, limited access to services and resources
Rates Overtime
1. 0.07 degrees per decade since 1880
Heatwaves
1. Increase due to high pressure, trapped air from Climate change
  1. Increased severity in urban areas, increased frequency
2. Risk for anyone in heat
  1. Heat exhaustion, heat stroke
Precipitation Events
1. Heavy rain caused by snowmelt, glacial outburst, coastal storms
  1. Flooding
2. Droughts
  1. Crop failure, soil erosion, dust storms, decreased water supplies,
    1. Fires

    1. Regulation of global cliamte
Hurricanes
1. Wind, rain, flooding, storm surge
  1. Post hurricane: rebuilding, infrastructure, decrease in human wellbeing
2. Caused by high humidity, no wind sheer, low pressure
3. Climate : storms retain higher destructive power for longer time
Sea ice melt
1. Raising sea level, extinction of small island nations, floods, storm surge
2. Polar vortex
