That's continuing a trend of bigger, more destructive fires.
But to what extent are these fires natural and to what extent are they human-driven? (Video via CBS)
But, as with so many things, humans have disrupted this natural process and made it more destructive. (Video via National Wildfire Suppression Association)
Through suppressing regular fires, for agriculture and development, humans likely have increased the frequency of severe fires, by allowing forest litter — like dead leaves and branches — to accumulate.
That litter also allows greenhouse gases to accumulate, which means those severe fires are also contributing to climate change.
Which is in turn leaving forests dryer and hotter, making it a lot easier to start those severe wildfires.
Especially in Alaska, which is currently seeing its worst ever wildfire season and, as the country's only Arctic state, is also warming twice as fast as the rest of the U.S., according to Climate Central. (Video via KTVA, NASA)
But it doesn't look like suppressing those fires will stop anytime soon. Settlement of wildfire-prone areas in Colorado, for example, is only increasing, and the government spends some $3 billion to protect settlement every year. (Video via YouTube / Show My Property TV)
