On Thursday afternoon, in the space of a few hours just a day before the new year, 100-plus-mph winds carried the most destructive fire in Colorado history through the suburban sprawl of greater Denver, destroying much of the towns of Louisville and Superior and forcing tens of thousands to flee, including many who had entered shopping malls from sunny skies just a few minutes before. As many as 1,000 homes were destroyed. Two people currently remain missing; if the death count stays at zero, Colorado governor Jared Polis said Friday, it would be “a New Year’s miracle.”

By the standards of the megafires and gigafires of the last few years, the Marshall Fire was quite small — 6,000 acres, all told, once it was finally, poetically, brought to an end by snowfall on New Year’s Eve. But following the driest and second-warmest fall in 150 years, the devastation was harrowing out of proportion to its scale, since, unlike most wildfire, it was not in wildland or forest but was — as the climate scientist Daniel Swain, who lives in Boulder, put it — an “urban firestorm.”

That may sound like hyperbole, but on Friday the governor echoed the language: “It wasn’t a wildfire in the forest, it was a suburban and urban fire. The Costco we all shop at, the Target we buy our kids’ clothes at — all damaged.” In fact, though the fire did not begin there, it quickly jumped to a strip of big-box stores and their parking lots — to most Americans perhaps the very picture of an inflammable Anthropocene.* But as Swain told me on Friday when we spoke by phone, “Fire finds a way.” The way, typically, is wind; during the Marshall Fire, it carried flames and embers at hurricane-force speed for eight straight hours, consuming “football-field lengths of land in seconds.” [Continue reading…]
