> With more cold deaths currently than heat deaths

I disagree even to that. Any numbers for that statement, at least rough dimensions?

And, given world average rising a few more °C, and we get a similar extreme weather condition persisting for few days like described here, but where wet bulb goes not just close/slightly but significantly over 35°C, what will that numbers be in poor.. but heck, even in rich countries?

You cannot be serious..

(Adding: Btw.. after all what models tell and we already see, we are in general not getting rid of extreme colds as well, but even getting also more persisting ones of these.. )
