Disaster Index: 5.8 Entry: Thermal Load, Pre-Brazil Cause: Scotland required to compete against Brazil in approximately 30°C heat — conditions outside normal preparation range for a nation whose climate averages 14°C in June. Category: Meteorological / Structural Evidence: Steve Clarke has confirmed heat management is an active concern. Scotland's qualifying campaign contained no fixture in comparable temperatures. Brazil have historically performed in this range. The gap is physiological before it is tactical. Historical precedent: Scotland 2–1 Morocco, St-Étienne, 1998. Heat was a documented factor in the second half. The score at half-time was 0–0. Affected parties: Outfield players carrying high-press or high-mileage roles. Squad depth at those positions. Immediate outlook: Manageable with correct preparation. The concern is not the temperature. The concern is what the temperature does to the margin. Filed: 22 June 2026 / pre-Brazil, Group A
