The statistics are alarming, but it’s difficult to imagine exactly how bad the situation is based solely on numbers. And since pictures paint a thousand words, here are some that illustrate exactly what they all mean.

As of writing, fires have killed people, destroyed homes, and damaged the natural habitats of the country’s unique wildlife, leaving many in danger. And according to experts, it looks like it won’t be put out any time soon .

A bushfire rages at an average speed of 22.53kph (14mph). That’s two times faster than a forest fire, which is usually at 10.78kph (6.7mph). It’s much faster than most people can run — about double the average running speed (9.81kph or 6.1mph) — which is why it’s so dangerous. Bushfires usually spread faster depending on the humidity, topography, wind, and temperature.

Australia is getting hotter

The country broke its all-time temperature record twice in December last year. An average maximum of 40.9°C was recorded on December 17, which was topped just a day later when it hit 41.9°C. These both beat the 40.3°C record set in 2013. And it’s bound to get even hotter, as temperatures usually peak in January and February.

Just how hot is 40 degrees? The optimum air temperature for the body is between 18°C and 24°C, according to the World Health Organization. Research shows that 40°C is dangerous to human health as the body struggles to cool itself, and could lead to death. In 2003, during the European heatwave that killed 70,000 people, temperatures in some areas repeatedly reached 40°C.
