I know these heat waves are affecting Europe compared to the US because they don't have AC to deal with it. I don't understand why this isn't an issue for parts of the world where they also don't have AC but reach these temperatures all the time? I'm not criticizing the people affected, I'm genuinely curious what's different in Europe compared to equatorial populations without AC? Or do people die from heat all the time in less wealthy countries and we just don't hear about it? I'm really sorry to see a headline like this, I'm not skeptical or critical, I just want to understand the world better.
