This study, led by scientists from Climate Analytics, an international climate science and policy institute, is first to show that just half a degree of extra warming between 1.5°C and 2°C makes a big difference in terms of heat stress risk posed to Muslims carrying out religious rites in Saudi Arabia during summer, where the mercury frequently climbs over 45°C even now.
