Before the beginning of the first day of the December 2006 Hajj, 243 pilgrims had died, according to a statement by the Saudi government.[39] The majority of deaths were reportedly related to heart problems, exhaustion in the elderly and people with weak health, caused by the heat and tiring physical work involved in the pilgrimage. After the conclusion of the Hajj, the Nigerian government reported that 33 nationals had died mostly "as a result of hypertension, diabetes and heart attack", not due to epidemic illnesses, and rejected assertions that Nigerian pilgrims died in an accident on a road to Mina.[40] Egypt's official news agency has reported that by 30 December (10 Dhu al-Hijjah), 22 Egyptian pilgrims had died.[41] Four Filipino pilgrims in their 50s died during the pilgrimage of illnesses or other 'natural causes', and were buried in Mecca.[42] The Pakistani Hajj Medical Commission has announced that approximately 130 Pakistani pilgrims died during the Hajj season in Saudi Arabia, "mostly aged and victims of pneumonia and heart patients", and that 66 pilgrims were admitted to Saudi hospitals for similar ailments.
Also, not to downplay the reality of climate change, but dying of heatstroke in Saudi Arabia in June was not exactly beyond the pale 100 years ago either.
Every year, for quite some time going forward, is gonna be worse than the year before, and no safety limit or anything like that until we actually start doing something about it
