I have noticed this too. It predictably appears whenever there is a heatwave. I also don't really see these articles reflecting reality - a lot of places have AC, its not really unaffordable to get a portable setup if you don't have one, and I don't know anyone refusing to get one because they are worried about the carbon emissions (especially here in France where electricity is almost all nuclear generated anyway). Yet there is a flood of articles and a predictable argument detached from reality every single time.
