Extreme Events are Hazardous to our health

  • Prolonged droughts fuel fires are releasing respirtory pollutants. In Southeast Asia, a high frequency of forest fires is likely to increase the risk of respiratory diseases.
  • Warmer climates, accompanied by doubling carbon dioxide will increase transmission capacity by 100 times for mosquitoes than in temperate zone.
  • Higher temperatures tend to increase bacterial levels and encourage the growth of toxic organisms, including those responsible for red tides (toxic algal outbreaks).
  • Increased temperatures, elevated atmospheric Co2 concentrations and longer growing seasons would enourage plant growth and pollen production. This will increase the risk of respiratory diseases.
  • Heat waves can reduce human productivity, and increase sickness and death.
  • Floods accelerate fungi growth, such as the house mould Stachybotrys atra, associated with lung disease among children.
  • Floods create mosquito-breeding sites : Malaria and Dengue prone areas are on the rise.
  • Heavy rainfall and floods flush dangerous microorgnisms, nutrients and pollutants into waterways.
  • Emergence of the new diseases. In some countries, diseases that were unheard of began to surface. These diseases are either associated with extreme drought or floods.
