Hurricanes explained: The Saffir-Simpson Scale
The Saffir-Simpson wind scale is used to classify Atlantic hurricanes into 5 categories. Learn what that means.
Wildfires are classified by the Environmental Protection Agency as natural disasters.
However, only 10-15% of them happen on their own in nature.
Most wildfires are caused by humans, and the most common causes are unattended camp and debris fires, discarded cigarettes, and arson. (source: National Geographic).

A wildfire, wildland fire or rural fire is an uncontrolled fire in an area of vegetation happening in rural areas.
Wildfires can rapidly burn millions of acres of land and can destroy everything—trees, homes, animals and humans in their paths. Families and whole communities that live in rural, wildfire-prone areas are in danger of losing their homes and having to flee for their own safety. Wildfires also have major health hazards, especially for people with existing breathing problems.
Breathing fire smoke can cause respiratory issues and coughing, wheezing and bronchitis. Another threat is carbon monoxide (CO). Inhaling CO reduces oxygen delivery to the body’s organs and tissues and can lead to headaches, nausea, dizziness and even premature death.

Climate change increases the occurrence and severity of wildfires.
Hotter weather, a result of climate change, makes forests and vegetation drier and therefore more prone to burning.
As a result, the average wildfire season is three and a half months longer than it was a few decades ago, and the number of annual large fires in the West has tripled.
As rising greenhouse gas emissions are increasing droughts and heat, more catastrophic wildfires are expected in the years to come, especially with the fire seasons getting longer.
Wildfire is the general umbrella term, whereas the term bushfire refers to an uncontrollable fire in bushland.
In simple terms, you can specifically refer to the type of wildfire depending on the vegetation present.
Australia is very prone to menacing bushfires.
The country’s climate is generally hot, dry and susceptible to drought.
At any time of the year, some parts of Australia suffer extremely damaging bushfires.
Bushfires tend to occur when light and heavy fuel loads in Eucalypt forests have dried out, usually following periods of low rainfall.
Have a look below at some facts and numbers about the devastating 2020 Australia bushfires.
