It only needs one day where the temperatures are significantly higher than in 1976 for the death rate to rise out of proportion to the rise in temperature.
The 1976 heatwave is understood to have been the cause of 20% "excess deaths" and there was a significantly increase in hospital emergency admissions from 24 June to 8 July 1976 than for the same period in 1975 or 1974. This compares to 59% excess deaths for the 2003 heatwave.

If these extra deaths do not cause you concern, that's fine, but do not pretend that 1976 did not have its victims, it is just that were all young and probably healthy, so unaware of all the old and ill who fell victim to it.

going on it would seem. The car park near to the beach is full and cars are parked up both sides of nearby roads. Not exactly staying home and keeping cool indoors, although I appreciate being by the sea is cooler but that is sirely as long as you keep in the shade of umbrella, wear a hat etc.
