Okay the problem is when you know it's just going to get hotter on average, it's already almost hot enough to kill people, and the weather changes frequently and increasingly unpredictably
You people shouldn't be seeing this as "oh it's the hot week of summer we just need to be stoic and British about it" and instead see it as "there's going to be increasing instances of Its So Hot Everybody Is Dying and we should Do Something About That"
