People talking about UK heatwave again and comparing to avg temp in most US states. People, a heatwave is a heatwave when the heat goes well above the norm, there's no point in comparing temperature from one place to another. Unless the comparison is to tell how worse it has got over time (e.g. having equator temperate when not near it). Can person from X survive heatwave at Y? Probably. But a better question would be, can person from X survive a heatwave at X? Because there will be one. Soon.
