In the record breaking heatwave of July 2019 when the record temperature of 38.7C was achieved on 25th July, there were over 8,000 heat related deaths. That is a major incident in mortality and obviously cannot be ignored. If the current heatwave is sustained over a longer period of time and the UK record is challenged, expect incidence of heat related deaths to be even higher.
I agree extreme weather events are very interesting, and any new records will obviously grab anyone's attention. But the danger to human life cannot be ignored either. It's a case of being a little bit careful of what you wish for.
