> Our ancestor figured out air climatisation as well This is a large, expensive structure, proving my point. You can't just wear more free animal skins and be fine. > Point is that way more people die from cold than from heat. That is the point in Montreal, but that is not the point in Vietnam. Their climate is precariously hot already (with high wet bulb temperatures, unlike in Iran), so a small imbalance in the upper extremes can kill a lot of poor people who don't have access to A/C. That should be no problem in 30 years if they are allowed to migrate to cooler countries, but the conservatives inside those colder countries have and will effectively ban that possibility for the large majority of them due to xenophobic attitudes. It's a rather disgusting situation given that these are the same people that lobbied for the pro-fossil fuel policies that will have put these people in the hot Global South in that predicament to begin with.
