World Cup heat claims still need match-level measurement. [1]

The paper's June 19 brief on the heat file waiting for match-level WBGT said player-safety arguments should not outrun the instrument. June 20 keeps that line. The available scientific source explains why wet-bulb globe temperature, threshold rules, cooling breaks, and operational details matter when heat is assessed for sport. [1]

That is a different story from ordinary weather. Temperature alone is not the full player-safety measure. WBGT incorporates heat, humidity, radiation, and wind into a more relevant operational number for athletes and medical staff. [1]

The divergence is predictable. X can turn every hot kickoff into proof of negligence, or dismiss heat warnings as soft-player theater. MSM can recap matches and mention weather without asking whether the actual threshold was measured on the field. A useful article needs the match-level WBGT, the kickoff time, cooling-break policy, medical staffing, and any official adjustment. [1]

The PubMed Central source gives the method frame, not today's missing table. [1] That distinction should be visible. It supports the claim that WBGT matters; it does not prove that a particular World Cup match crossed a threshold. The article therefore stays in the standards lane until FIFA, FIFPRO, a city, a team doctor, a broadcast operator, or a venue publishes the operational reading.

No verified X status URL appears in the memo. That is acceptable because the story is about measurement discipline. The discourse is obvious; the data is not yet in the packet. [1]

The next heat article should name a match and a number. Without that, the paper can say the safety claim is plausible and method-sensitive, but it cannot say the public record has proven it.
