Fun facts: "killer bees" are also known as "africanized bees". In the 1970s there was great alarm in the US about the spread of africanized bee strains because they're so much more aggressive than European bees. There was even a terrible horror movie about it, but this particular catastrophe never materialized. I had a friend in graduate school in the '90s who was part of a team of scientists investigating the problem. It turns out that if you raise an africanized queen in a temperate climate, the bees she produces are no more aggressive than European bees; likewise, a European queen raised in a hot, tropical climate produces bees just as hyper-aggressive as typical africanized bees. So the entire thing was just bee racism all along. Bracism?

Of course global heating is going to make this a bigger problem everywhere, but fortunately we'll be fucked a lot worse by all the other problems this is going to produce.
