The wildfire in north-eastern Alberta was sparked on May 1 and, fed by hot weather and tinder dry terrain, quickly flared up to a massive wildfire that has been nicknamed "The Beast".

Officials warned only significant rainfall could fully halt its spread. The blaze has scorched a staggering 161,000 hectares, or 1610 square kilometres, officials said. To put that into perspective, from the coast to Mundaring, and from the Gnangara state forest in the north to Jarrahdale in the south, it would completely engulf Perth.

The Canadian blaze is so hot and so intense that it has formed its own weather system. The thundercloud produced by the blaze is creating its own lightning, and consequently setting more trees alight, CNN reports.

That's roughly the equivalent of evacuating the entire city of Mandurah. Officials have reported that at least 1600 properties in Fort McMurray had been destroyed. The blaze has scorched a staggering 161,000 hectares, or 1610 square kilometres, officials said.

Professor Bowman has just returned from Canada, where he had received a fellowship with the University of British Columbia to study fire ecology there. He agrees with fire expert Mike Flannigan from Alberta, who said that what was happening in Canada was entirely consistent with climate change. As a result, more of these types of huge fires could be expected. It sounds extreme, our cities could burn down, or parts of our suburbs could burn down, but it could happen. Professor David Bowman Professor Bowman said he was in western Canada at the start of the northern spring, which felt more like summer. Precipitation was low, about half of the average, and what snow there was melted early. April was exceptionally mild, with temperatures regularly in the 20s, while it even passed 30 degrees at the start of May. That is 15 degrees above the region's average May maximum.

"What I'm seeing all around the world now is clear evidence of the consequences of changing climate, which is adding that extra bit to an already messed-up problem," Professor Bowman said. "That's a key thing: all climate change is doing is making a really serious problem really, really serious. "Certainly this time of year [around Fort McMurray] there should have been a deep snowpack, and it should have just been a big soggy mess. "In modern times, the scale of this evacuation and the number of houses being burnt and the fact that the drama is still unfolding, I can't think of anything vaguely comparable in Australia. It's really the perfect nightmare." Professor Bowman said there were a couple of "really big take-home messages" for Australia from the situation in Canada.

One of those was realising that this could happen in Australian cities, and that residents needed to "take responsibility for living in these dangerous, flammable places". Residents needed to prepare their houses properly, have an evacuation plan, and not rely on the idea that "someone's going to come and put the fire out" if a bushfire did break out, he said. "I think the fire experts understand how bad things can get. What I think these fire events are doing is bringing right up into the consciousness of the general public the scale of this problem," he said. "Most people sort of have an awareness of it, but it's somebody else's problem and they're underestimating the risk. There just isn't a high level of situational awareness that this scale of catastrophe could happen. "Hopefully we can start cutting through and getting some serious traction and serious engagement. "Living in flammable environments is not 100 per cent safe and we're seeing a whole complex [group] of factors building up to the nightmare scenario. It sounds extreme, our cities could burn down, or parts of our suburbs could burn down, but it could happen."
