Forest fires raged in western Canada, Govt extended state of emergency

As forest fires raged in western Canada, the provincial government extended a state of emergency and announced aid for tens of thousands of people evacuated because of the disaster. 

Firefighting officials said, around 140 fires were burning in British Columbia on the Pacific coast, and more than half of them remained out of control. Four of those 140 — down from an earlier figure of 150 — are newly declared fires. All told the flames have forced at least 46,000 people from their homes.

British Columbia Premier John Horgan said, each household evacuated will receive aid of 480 dollars. That amount will double for families unable to return home over the next two weeks. He also said a state of emergency that was first declared July 7 and set to expire tomorrow will be extended by two weeks.

About Wildfires

  • A wildfire or wildland fire is a fire in an area of combustible vegetation that occurs in the countryside or rural area. Depending on the type of vegetation where it occurs,
  • a wildfire can be classified more specifically as a brush fire, bush fire, desert fire, forest fire, grass fire, hill fire, peat fire, vegetation fire, or veld fire.
  • Wildfires can be characterized in terms of the cause of ignition, their physical properties, the combustible material present, and the effect of weather on the fire.
  • Wildfires can cause damage to property and human life, but they have many beneficial effects on native vegetation, animals, and ecosystems that have evolved with fire. Many plant species depend on the effects of fire for growth and reproduction.

Causes

  • lightning
  • sparks from rockfalls
  • spontaneous combustion
  • volcanic eruption

Wild fire affects the atmospheric weather, climate, Ecology of forest, and nature  directly or undirectly such as Heat Waves, El Nino, droughts and cylindrical climate changes even it affects regional weather pattern such as high pressures ridges that can increase risk and ulter the behaviour of wild life dramatically.
