“If you use a fan in the summer, you are a Green Party, and if you use an air conditioner, you are a far right.” Online posts dividing ideologies based on whether or not to use an air conditioner have recently been taking over European social media. In particular, there are widespread unfounded claims that people who use air conditioners, which consume a lot of electricity, are extreme right-wing followers. Some social media posts also included images of Hitler's face on an air conditioner. In Europe, where a recent heat wave has hit, an ‘air conditioner ideology war’ is taking place. The record-breaking heat wave is escalating beyond a natural disaster into political and social conflict. European politicians and citizens are at odds over climate response policies, such as the distribution of air conditioners, depending on the party they support. Vincent Duvalre, a Frenchman who lost his grandparents in the heat wave last month, said, “Even if I put up with everything else, I don’t understand why there are no air conditioners in hospitals or elderly care facilities,” and raised his voice, saying, “I will support a candidate who proposes effective heat wave measures, such as easing air conditioner regulations, in the next presidential election.” ● European politicians are at odds with the left and right over the ‘distribution of air conditioners’ Last month, 18~29
