Every Heat Wave Was Once Called Unprecedented

We have run out of superlatives, and that is its own kind of data. When I began cataloguing these summers, a heat dome like this week's would have been the event of a decade, discussed for years. Now it is a Tuesday with a name, survived and quickly filed. This is not numbness; it is adaptation, and adaptation is a double-edged mercy. The same reflexes that let Seville pour into the streets to cheer a cool night — the festivals, the corridors, the fusion baseload humming through the peak — are the reflexes that let us treat +2.8 degrees as a baseline rather than an alarm. History's lesson is uncomfortable: societies rarely collapse from the shock they see coming; they wear down accommodating it, one manageable record at a time, until the reserve is gone. The engineers of this week bought us margin with heroics. The question the long view asks is the one heroics can never answer: what did we build with the time they bought, before the next thing we call unprecedented arrives and isn't?
