A GWL of 1.5°C could result in 30,000 annual deaths due to extreme heat, with up to threefold the number under 3ºC GWL  . The risk of heat stress, including mortality and discomfort, is dependent on socioeconomic development . Heat stress risks will be lower under SSP1 than the SSP3 or SSP4 scenarios  . The incidence of heat-related mortality and morbidity will be highest in SEU, where their magnitude is also expected to increase more rapidly . WCE, NEU and SEU will experience accelerating negative consequences beyond 1.5°C GWL, particularly under SSP3 and SSP4 due to higher vulnerability compared with SSP1 . The number of heat-related respiratory hospital admissions is projected to increase from 11,000  to 26,000 annually , particularly in SEU mainly due to a relative increase in the number of extremely hot days . Cold spells are projected to decrease across Europe, particularly in Southern Europe, but do not compensate for the additional heat-related deaths projected .
