Smoke is no longer the problem; the problem is heat. A real fire is hard to protect against. People think they know what it is—they use gas hobs and charcoal grills and believe they have tamed the flame, but even a small blaze can be terribly dangerous. A big one—room-sized, house-sized—is not just more of the same. It is a ferocious, consuming power, lethally radiant. If we are not rescued soon—if the fire is not extinguished—we will be baked in here like potatoes.
