Global fires are the sum of our choices. Climate change, ecology and fire suppression have combined to bring us the return of the ''urban firestorm''.

When the fire historian Stephen Payne says that we are now living in the ''Pyrocene,'' this is part of what he means : Forest fires are now burning twice as much tree cover, globally, as they did just 20 years ago, and the world is quickly inuring itself to that fact.

In parts of the world as far-flung as Fort McMurray, Alberta; Lahaina, Hawaii; Boulder County, Colo.; and now Valparaiso, Chile - where at least 15,000 homes have been destroyed - the new age of fire has produced what the climate scientist Daniel Swain has called the return of the ''urban platform.''

Of the 10 deadliest fires on Earth since 1900, five have occurred since 2018.

In Early February the deadliest South American wildfires in a century swept through Valparaiso, Chile, killing at least 112 people.

It was almost six months to the day since the deadliest American fires in a century killed more than 100 people where flames tore through Lahaina,in Maui, burning up much of the Hawaii's precolonial capital and forcing residents to jump into the ocean for safety, the flames leaping over them to ignite the boats docked in the harbor.

Two record-setting episodes of fire death in half a year might once have looked like a world historical ecological coincidence, but it has been a year of fire extremes - and a year in which the world has mostly whistled past them.

In the United States, mercifully little land burned - only 2.6 million acres, which was less than half the recent average.

But in Canada, fires are through more than twice as much forest as the country's previous modern record, the total burn scar large enough that more than half the world's countries could fit inside.

In Greece, one fire forced the country's largest ever evacuation, and another became the largest fire in the history of the European Union.

And in Australia, the bush fire season has burned over 150 million acres - three times the land burned last year in Canada and more than twice as much land as was destroyed in Australia's Black Summer of 2019-20.

Sydney Harbour was choked with smoke that ferries couldn't navigate the waters, at least a billion animals were consumed by flames and panicked evacuees had to be rescued from from a beach by military helicopters.

How did it get this way? The intuitive, conventional answer is climate change. But where people choose to live matters, too. And in the United States, especially, you increasingly hear a somewhat contrarian explanation that emphasizes fire suppression than warming.
