How is it reductive? Literally speaking, climate change will most impact the people who benefited the least from the burning of fossil fuels. Those are the people who come from poor and hot countries in the global south and near the equator, who have historically burned far less fossil fuels per-capita, but nevertheless will be harmed the most per-capita given their climates are already precarious. Then, when the consequences boil over in a few decades and their countries become too hot to be healthily habitable, they will be banned from migrating to colder, richer countries by those countries' local conservatives, who will lobby government to restrict or ban immigration intake. What a sick and hypocritical situation that will be. Those rich and cold countries' wealth was generated by the fossil fuels that were burned that put those poor people in the global south in that awful predicament to begin with, and now they'll be stuck there to deal with the consequences that they didn't primarily create. It's a world-scale theft of opportunity, wealth and life.
